certain situations if polyphonic data was passed from "note" handler to
Bumped version (2.1.1.svn64).
* NKSP parser: Fixed crash if unary '-' operator was used on a non-number
NKSP parser: Raise parser error if either unary '-' or '+' operator was
used with a non-number data type.
Tests: Added test cases for the fixed issues described above.
Bumped version (2.1.1.svn63).
* Test Cases: Fixed deadlock of Condition test on Linux.
NKSP: Fixed built-in exit() function to behave as return statement.
VM API: Introduced new signal STMT_RETURN_SIGNALLED.
NKSP exit() function: signal STMT_RETURN_SIGNALLED instead of
NKSP AST: Introduced common base class 'Subroutine' for 'EventHandler'
and for new 'UserFunction' class.
NKSP parser: Use 'UserFunction' class instead of 'Statements' class
for user declared NKSP functions.
ScriptVM: Handle new STMT_RETURN_SIGNALLED signal by unwinding the
stack to previous, calling subroutine.
NKSP tests: Added test cases for exit() acting as return statement.
Bumped version (2.1.1.svn62).
* Fixed rare crash when switching between instruments that had instrument
Bumped version (2.1.1.svn61).
* NKSP language: emit warning if an array variable was declared with bigger
array size than amount of initial values been assigned, and initialize the
missing array elements with zero in this case.
Bumped version (2.1.1.svn60).
NKSP: Relaxed array variable declaration.
NKSP: Just throw a warning, not an error if an array variable of
size zero was declared.
NKSP: Allow omitting explicit array size on array variable declaration
if combined with immediate value assignment
(e.g. declare %foo := ( 1, 2, 3 ) ).
Bumped version (2.1.1.svn59).
* Fixed compilation error with Bison >= 3.6.0.
Bumped version (2.1.1.svn58).
* NKSP: Fixed crash when undefined variable was referenced.
Bumped version (2.1.1.svn57).
Ref<> smart pointer class is now thread-safe.
Require C11 compliant compiler.
Ref<> class: Implemented lock-free & wait-free thread-safety.
Ref<> class: Use portable format specifier %p for pointers.
Bumped version (2.1.1.svn56).
* Ref<> class: prevent compiler error if T == T_Base
(due to method signature duplicate).
Bumped version (2.1.1.svn55).
Fixed deadlocks (e.g. when restarting engines).
Individual thread implementations (e.g. disk thread, etc.):
Disable thread cancellation on critical sections, e.g. when holding
mutex locks, to prevent deadlocks if thread is stopped and/or
Added TestCancel() calls to thread implementations if missing.
No need to wrap Thread::TestCancel() calls into
CONFIG_PTHREAD_TESTCANCEL macro conditions (since TestCancel() is
already a stub on systems which don't have pthread_testcancel()
If compiled for debugging: give each thread a human readable name
to simplify debugging of multi-threading issues.
DiskThreadBase: TestCancel() and pthread_testcancel() calls are
per-se redundant, so only call TestCancel().
Added missing override keywords to silent compiler warnings.
Bumped version (2.1.1.svn54).
Mutex class: Implemented bug detection and deadlock debugging features.
Bug detection: By enabling macro DEBUG_MUTEX at compile time and
calling new method setDebugEnabled(true) at runtime, automatic bug
detection features are activated which e.g. raise an assertion fault
if a thread attempts to Unlock() a thread it does not own a lock on,
or when locking more than once while not using mutex type RECURSIVE
and much more.
Deadlock debugging: Also if these features were activated like
described above, the most recent mutex lock is recorded by capturing
the name of the thread and the precise call stack which caused the
mutex lock. This information can be used to identify the exact
situation that lead to a dead lock efficiently with a debugger.
Bumped version (2.1.1.svn53).
Thread class: Added new methods (POSIX implementation only yet):
Added methods pushCancelable() and popCancelable() for allowing to
prevent thread being terminated on critical sections.
Added methods name(), nameOfCaller() and setNameOfCaller() to allow
assigning threads human readable names for debugging purposes.
configure: Always check for availability of pthread_testcancel()
and use it if so (previously it was only used if explicitly enabled
by configure script option).
Raise a compiler warning if pthread_testcancel() is not available.
Bumped version (2.1.1.svn52).
* Implemented global backtraceAsString() function for debugging purposes
(POSIX systems only, no Windows implementation yet).
Bumped version (2.1.1.svn51).
* NKSP: Fixed re-entrant issue with function calls which caused wrong
result values if the same function was called multiple times in a term
(specifically if metric prefixes were used).
Tests: Added NKSP core language test cases to guard this fixed issue.
Bumped version (2.1.1.svn50).
* NKSP: Fixed intermediate function result values never having reflected
any standard measuring unit type.
Tests: Guard this fixed NKSP issue by test cases.
Bumped version (2.1.1.svn49).
* NKSP: Fixed incorrect EG times if standard measuring unit was
passed to built-in functions "change_attack()", "change_decay()"
Bumped version (2.1.1.svn48).
* Added configure checks whether C++ compiler supports so called
Bumped version (2.1.1.svn47).
NKSP: Added support for 'patch' variables.

(as new dedicated keyword 'patch').
NKSP parser: capture locations of 'patch' variable declarations
in script's source code.
ScriptVM: Allow patching 'patch' script variables by replacing
their default assignment expression with a supplied replacement
variable initialization expression by optional 2nd argument when
ScriptVM: Allow retrieval of default initialization expressions
of all 'patch' variables by optional 3rd argument when calling
loadScript() (i.e. for instrument editors).
gig engine: Implemented support for loading real-time instrument
scripts with 'patch' variables bundled with gig instruments.
Bumped version (2.1.1.svn46).
NKSP parser: track code locations also by raw byte position and length.
NKSP VM API: Added member variables 'firstByte' and 'lengthBytes' to
NKSP Editor API: Added methods firstByte() and lengthBytes() to
NKSP VM language parser: track all positions also by raw byte offset
and length (along to the already existing tracking by line/column).
NKSP editor syntax highlighting scanner: track all positions also by
raw byte offset and length (along to the already existing tracking by
Bumped version (2.1.1.svn45).
NKSP: Reduced code for parsing NKSP variable declarations:
Use 2 generalized grammar rules with optional components (i.e. optional
value assignment and optional variable qualifiers) instead of previous
linear combinations of grammar rules, which also fixes some edge case.
Bumped version (2.1.1.svn44).
Fixed potential crash with high pitch at end of RAM playback:
AbstractVoice: variable 'cachedsamples' is already in sample points,
so the previous division by amount of audio channels, allowed RAM
playback to exceed beyond the amount of samples being cached.
Bumped version (2.1.1.svn43).
* Fixed playing noise at the end of a disk stream under certain
Bumped version (2.1.1.svn42).
* Fixed crash when editing key groups (a.k.a. exclusive groups)
with an instrument editor during playback.
Bumped version (2.1.1.svn41).
* gig engine: If minimum cutoff is defined, remap cutoff controller CC
values to really span the entire possible cutoff range (to avoid a
dead controller zone).
Bumped version (2.1.1.svn40).
* gig engine: Fixed potential crash with polynomial interpolator
and max. pitch.
Bumped version (2.1.1.svn39).
* NKSP: Removed upper value constraint for 2nd argument of built-in
functions "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
"change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
"change_pitch_lfo_depth()", to allow e.g. passing value 2000000
to double the LFO frequency / resonance / cutoff frequency.
Bumped version (2.1.1.svn38).
NKSP: Fixed crash with built-in functions returning an array.
Calling built-in functions returning an array type was broken and
caused a crash when built-in function's NULL (supposed to be array)
result value was used by the script VM.
Bumped version (2.1.1.svn37).
Fixed compile errors with C++17:
std::ptr_fun was removed from STL in C++17,
use C++11 lambda expression instead.
std::mem_fun and std::bind2nd were removed from STL in C++17,
use C++11 lambda expression instead.
Bumped version (2.1.1.svn36).
* Added support for 'null function RPN/NRPN' (which is RPN/NRPN
parameter MSB=127 and LSB=127, and which is disabling subsequent
data entry/increment/decrement CC messages.
Bumped version (2.1.1.svn35).
* Added support for MIDI CC #96 (data increment).
Added support for MIDI CC #97 (data decrement).
Bumped version (2.1.1.svn34).
Implemented support for compressed RPN/NRPN message sequences:
Allow processing MIDI data entry messages without having to be
preceded strictly always by RPN/NRPN parameter selection messages
prior to each value change (i.e. data entry CC).
Bumped version (2.1.1.svn33).
* NKSP: Fixed certain built-in variables having returned
some (seemingly random) metric unit factor (instead of none).
Bumped version (2.1.1.svn32).
* NKSP: Implemented built-in script function "set_rpn()".
NKSP: Implemented built-in script function "set_nrpn()".
Bumped version (2.1.1.svn31).
NKSP: Added support for RPN and NRPN event handlers:
NKSP language: Added support for RPN event handler
("on rpn ... end on" in instrument scripts).
NKSP language: Added support for NRPN event handler
("on nrpn ... end on" in instrument scripts).
Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
may be read from the new RPN/NRPN script handlers to get the (N)RPN
parameter that had been changed and its new value.
Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
which are identifying the new (N)RPN handlers as such at script runtime.
Bumped version (2.1.1.svn30).
Added support for MIDI CC #38 (data entry LSB):
Combine data entry MSB and data entry LSB events' values to one 14-bit
value, which allows higher resolution (N)RPN value handling.
Handle now hard coded RPN events in separate method
Handle now hard coded NRPN events in separate method
Bumped version (2.1.1.svn29).
EngineChannel: Overhaul of RPN / NRPN related methods:
Added new *Rpn*Parameter*() methods as replacement for previous
*Rpn*Controller*() methods and marked the old ones as deprecated.
Added new *Nrpn*Parameter*() methods as replacement for previous
*Nrpn*Controller*() methods and marked the old ones as deprecated.
The new GetMidiRpnParameter() and GetMidiNrpnParameter() methods
return their result as common (in MIDI world) 14 bit representation
of sender's MSB and LSB values, instead of the uncommon 16 bit
representation of the old GetMidiRpnController() and
Bumped version (2.1.1.svn28).
* Event:Init(): memset() entire Event::Param union to zero instead of trying
to do that for its individual members; the latter became error prone due
to the union's growing complexity meanwhile.
Bumped version (2.1.1.svn27).
* NKSP: Added built-in script functions "msb()" and "lsb()".
Bumped version (2.1.1.svn26).
* gig engine: Fixed cutoff controller handling for new filter types.
Bumped version (2.1.1.svn25).
* gig format extension: Support for additional filter types:
lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
Bumped version (2.1.1.svn24).
* Using now cubic interpolation as resampling algorithm by default; and
linear interpolation is deprecated now.
Bumped version (2.1.1.svn23).
* gig format extension: Added support for different LFO wave forms
(currently either sine [default], triangle, saw or square).
gig format extension: Added support for LFO phase displacement
gig format extension: Added support for flipping LFO polarity on LFO 3
(in the original gig format this was only available for LFO 1 and LFO 2).
Bumped version (2.1.1.svn22).
* Gig engine: Changed default wave form for all 3 LFOs to sine
(instead of triangle; see discussion "GigaStudio LFO
compatibility" on mailing list from 2019-09-26 for details).
Bumped version (2.1.1.svn21).
* Gig engine: changed LFO start levels; LFO1 and LFO2 both to mid,
LFO3 to max. start level (see discussion "GigaStudio LFO
compatibility" on mailing list from 2019-09-26 for details).
Bumped version (2.1.1.svn20).
Refactored LFO class names and their header file names:
Renamed PulseLFO -> LFOPulse, LFOSawIntMath -> LFOSawIntMathNew,
SawLFO -> LFOSawIntMathOld, SineLFO -> LFOSineBuiltinFn,
LFOSine -> LFOSineNumericComplexNr, SquareLFO -> LFOSquarePulse.
Separated LFOSquarePulse (previously "SquareLFO") to its own
Renamed type LFOSigned -> LFOTriangleSigned.
Renamed type LFOUnsigned -> LFOTriangleUnsigned.
Bumped version (2.1.1.svn19).
Added new LFO implementations:
Added int math square LFO implementation.
Added int math saw LFO implementation.
Added numeric complex nr sine LFO implementation.
Added public API C++ class "LFO", which is a cluster class
encapsulating all the sampler's LFO implementations to be used by
3rd party applications (e.g. by Gigedit).
Marked class LFOTriangleDiHarmonic as deprecated
(will be removed in future).
Added LFOAll.h which includes all LFO implementation's header files.
Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
algorithm (since result of 2nd run was not accumulated).
Added benchmark for saw wave (benchmarks/saw.cpp).
Added benchmark for sine wave (benchmarks/sine.cpp).
Added benchmark for square wave (benchmarks/square.cpp).
Increased amount of benchmarks runs by factor 6 to achieve benchmark
times which are large enough on modern systems.
Cleanup of LFO APIs.
Bumped version (2.1.1.svn18).
* LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
behaviour for start_level_mid.

"floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
"sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
Bumped version (2.1.1.svn14).
NKSP: Built-in instrument functions fixes & hardening:
Fixed the following built-in functions having misinterpreted values given
with unit type (for their 2nd argument) as if they were relative values
(that is as if they were passed without a unit type): "change_attack()",
"change_decay()", "change_release()", "change_cutoff_attack()",
Fixed the following built-in functions having applied completely wrong
'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
respective EGs being their modulation sink assume uint data type with
value range 0..1000 instead of 0.0..1.0.
Added individual parse-time checks of function arguments for the following
built-in functions: "play_note()", "note_off()", "set_event_mark()",
"delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
"change_decay()", "change_release()", "change_cutoff_attack()",
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
Don't abort function call if unit type was used and at the same time
'final' operator was omitted for the primary value argument of the
following built-in functions: "change_cutoff()", "change_attack()",
"change_decay()", "change_release()", "change_cutoff_attack()",
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
"change_pan_time()", instead imply 'final'ness at runtime and raise an
appropriate parser warning at parse time.
Bumped version (2.1.1.svn13).
NKSP: Real number support for core instrument built-in functions.
NKSP: Built-in function "play_note()" accepts now real numbers and
seconds as unit type as well for its 3rd and 4th function arguments.
NKSP: The following built-in functions accept now real numbers as well for
their 2nd function argument: "change_vol()", "change_tune()",
"change_cutoff()", "change_attack()", "change_decay()",
"change_release()", "change_sustain()", "change_cutoff_attack()",
"change_vol_time()", "change_tune_time()", "change_pan_time()",
"fade_in()", "fade_out()", "change_play_pos()".
NKSP: Fixed built-in function "change_play_pos()" not having accepted
metric prefixes at all.
Bumped version (2.1.1.svn12).
* NKSP language: Fixed assignment to array variables which was
broken by floating point support introduction (svn r3573).
Test cases: Added NKSP int array and real array tests for value
assignment and initialization of arrays.
Bumped version (2.1.1.svn11).
NKSP: Cleanup regarding multiple data types for built-in function args.
NKSP VM API cleanup: Get rid of legacy method
VMFunction::argType(vmint iArg) which was already superseded by its new
replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
NKSP parser: if wrong argument type was passed to a built-in function and
that built-in function accepts more than one data type for the argument,
then show all supported data types as parser error message.
Bumped version (2.1.1.svn10).
* NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
as convenient methods for automatically converting values to expected
metric value basis.
NKSP built-in function "wait()" accepts now both integers and real numbers
Bumped version (2.1.1.svn9).
NKSP: Allow more wider support of standard measuring units & 'final'ness.
Raised compiler requirement to be C++14 compliant (due to severe
restrictions regarding C-style aggregate initializer lists in C++11
which are now massively used throughout the code base).
NKSP VM API: Allow units and 'final'ness to be returned as result from
built-in functions (added methods VMFunction::returnUnitType() and
VMFunction::returnsFinal() for that purpose which must be implemented by
built-in function implementations).
NKSP language: Allow metric unit prefixes of numeric scalar and array
variables to be changed freely at runtime (unlike unit types like Hz etc.
which are still sticky parse-time features of variables which cannot be
changed at runtime for the intentional sake of determinism).
NKSP language: 'final' values are prohibited for array variables for now
(attempt causes a parsers error).
NKSP language: expressions with unit types (e.g. Hz) are prohibited for
conditions of runtime control structures like if(), while(), select()
(attempt causes a parser error).
NKSP VM API: Allow built-in functions to perform their own, individual
parse time checks of arguments going to be passed to the function at
runtime (added method VMFunction::checkArgs() for that purpose).
NKSP language: raise parser warning if only one operand of binary
operators (like logical 'or' comparison) contain a 'final' value (because
it would always yield in a 'final' result in such cases).
NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
different metric unit prefixes, which will behave as expected (e.g.
result of expression '1000us < 2ms' is true).
NKSP language: Allow adding values with different metric unit prefixes
(e.g. result of expression '100Hz + 5kHz' is '5100Hz').
NKSP language: Allow subtracting values with different metric unit
prefixes (e.g. result of expression '1ms - 20us' is '980us').
NKSP language: Allow multiplying with any metric unit prefixes
(e.g. result of expression '2k * 3ms' is '6s'), however multiplications
with unit types on both sides (e.g. '2s * 2s') is still prohibited since
we don't have any considerable practical use for a term like '4s^2'
(hence any attempt multiplying two unit types still causes parser error).
NKSP language: Allow dividing by any metric unit prefixes and allow
division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
yields in unit free result '8'). So this is now a way to cast units away
e.g. for passing the result to other expressions, certain function calls
or variables which are not accepting any units (or that specific unit).
NKSP language: integer arrays and real number arrays can now be converted
to strings (e.g. for dumping their content with message() calls for
script debugging purposes).
NKSP language: expressions and variables with units are now correctly
casted to strings (e.g. with message() calls).
NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
floating point tolerances into account.
NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
'VMIntArrayExpr' and 'VMRealArrayExpr'.
NKSP VM API: replaced all unitPrefix() (parse time) methods by
unitFactor() (runtime) methods.
Built-in function "exit()" supports now returning units and 'final'ness
exclusively for test cases.
The following built-in functions support now units as well: "abs()",
"random()", "inc()", "dec()", "in_range()", "min()", "max()",
"real_to_int()", "int()", "int_to_real()" and "real()".
Built-in functions "array_equal()", "search()" and "sort()" support now
real number arrays (correctly) as well.
Added individual parse time checks of arguments to be passed to built-in
functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
"array_equal()" and "search()" specific for their individual purposes.
Test cases: Added massive amount of NKSP test cases for standard
measuring units and 'final' operator usage cases.
Test cases: Added NKSP test cases for (floating point tolerance aware)
real number equalness / unequalness comparison.
Bumped version (2.1.1.svn8).
NKSP: Introducing variable return type for built-in functions.
Changed method signature VMFunction::returnType() ->
VMFunction::returnType(VMFnArgs* args) to allow built-in
functions to proclaim a different result value type depending
on the arguments to be passed to the function.
Built-in script function abs() optionally accepts and returns
Built-in script functions min() and max() optionally accept
real number arguments and return real number as result in that
Added real number test cases for the built-in abs(), min() and
Bumped version (2.1.1.svn7).
NKSP: Added some initial floating point test cases.
RTMath: Implemented floating point comparison methods
fEqual32(float,float) and fEqual64(double,double)
which take the expected floating point tolerances
NKSP: Allow built-in exit() function to potentially
accept real type argument as well.
NKSP: Added real number test cases for built-in
functions exit(), int_to_real(), real(), real_to_int()
and int(), as well as for the plus, minus and negate
NKSP: Cleanup of class inheritance scheme.
scriptvm/tree.h: Mark all relevant classes with C++11 'final' keyword.
scriptvm/tree.h: StringLiteral class has no need for virtually.
NKSP: Introducing floating point support.
NKSP language: Added support for NKSP real number literals and
arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
NKSP language: Added support for NKSP real number (floating point)
script variables (declare ~foo := 3.4).
NKSP language: Added support for NKSP real number (floating point)
array script variables (declare ?foo := ( 1.1, 2.7, 49.0 )).
NKSP built-in script function "message()" accepts now real number
argument as well.
Added built-in NKSP script function "real_to_int()" and its short
hand form "int()" for casting from real number to integer in NKSP
Added built-in NKSP script function "int_to_real()" and its short
hand form "real()" for casting from integer to real number in NKSP
Bumped version (2.1.1.svn6).
NKSP: Bug fixes regarding new measurement units feature:
Fix: Engine internal Fade of script synthesis parameters volume, pitch
and pan were not rendered at all.
Fix: Backward compatibility of built-in function arguments without a
metric unit prefix was broken (resulted in incorrect value
Fix: built-in script function change_play_pos() resolved wrong arguments.
Bumped version (2.1.1.svn5).
* NKSP script editor API: Added support for detecting standard unit tokens
and their potential metric prefix token.
NKSP: Added standard units support for numbers and final "!" operator:
NKSP strictness: Variable names, function names and preprocessor condition
names must start with a regular character (a-z or A-Z); starting them with
a digit or underscore is no longer allowed.
NKSP parser fix: equal comparison operator "=" and not equal comparison
operator "#" must only accept integer operands.
NKSP language: Implemented support for standard units like Hertz, seconds,
Bel including support for metric unit prefixes; so one can now e.g.
conveniently use numbers in scripts like "5us" meaning "5 microseconds",
or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
"minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
NKSP language: Introduced "final" operator "!" which is specifically
intended for synthesis parameter values to denote that the synthesis
parameter value is intended to be the "final" value for that synthesis
parameter that should explicitly be used by the engine and thus causing
the sampler engine to ignore all other modulation sources for the same
synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
variable or formula with this new "!" operator the expression is marked as
Bumped version (2.1.1.svn4).
* NKSP: Introducing 64 bit support for NKSP integer scripts
variables (declare $foo).
Require C++11 compiler support.

* Test cases: Fixed thread tests segfaulting on Linux.
* Added test cases for NKSP core language aspects and core built-in
NKSP: Added method ScriptVM::setExitResultEnabled() which allows
to explicitly enable the built-in exit() function to optionally
accept one function argument; the value of the passed exit()
function argument will then become available by calling
VMExecContext::exitResult() after script execution.

Bumped version (2.0.0.svn68).
* Got rid of resembling an ancient GSt misbehavior which did not pitch at
all if an up-pitch of more than 40 semi tones was requested (I don't

intuitive behavior if used in combination with "change_vol_time()" or
"change_tune_time()" respectively: now tuning/volume changes are only
assigned (without delay) immediately to a new note if the respective
timing function has not been called before, otherwise the volume/tuning
changes are automatically faded (before, only the event's time stamp was
Bumped version (2.0.0.svn50).

* NKSP: Fixed all change_*() built-in script functions to apply their
synthesis parameter changes immediately in case the respective note
was triggered at the same time, instead of scheduling the parameter

and note_off(), which must be distinguished engine internally
from "real" MIDI note on/off events in order to avoid
misbehaviors like hanging notes.
Bumped version (2.0.0.svn13).

(CC #64) events.
Fix: Release trigger voices can now also distinguish correctly between
note-off and sustain pedal up events.
Bumped version (2.0.0.svn10).
* NKSP language grammar correction: allow empty event handler bodies
like "on note end on".
Bumped version (2.0.0.svn9).

auto detect whether it (sh/c)ould output its messages in color.
Fixed behavior of built-in script function "ignore_event()".
Bumped version (2.0.0.svn4).
* All engines: Active voices are now internally grouped to "Note" objects,
instead of being directly assigned to a keyboard key. This allows more
fine graded processing of voices, which is i.e. required for certain
instrument script features.
Built-in script function "play_note()": Added support for passing
special value -1 for "duration-us" argument, which will cause the
triggered note to be released once the original note was released.
Bumped version (2.0.0.svn3).
* All engines: Implemented scheduler for delayed MIDI events and for
suspended real-time instrument scripts.
Real-Time instrument scripts: Implemented support for built-in "wait()"
function's "duration-us" argument, thus scripts using this function are
now correctly resumed after the requested amount of microseconds.

"play_note()" function's "duration-us" argument, thus notes triggered
with this argument are now correctly released after the requested amount
Real-Time instrument scripts: Fixed crash which happened when trying to

Real-Time instrument scripts: Script events were not cleared when
engine channel was reset, potentially causing undefined behavior.
All engines: Attempt to partly fix resetting engine channels vs.
resetting engine, an overall cleanup of the Reset*(),
ConnectAudioDevice(), DisconnectAudioDevice() API methods would still be
desirable though, because the current situation is still inconsistent
and error prone.
Bumped version (2.0.0.svn2).

and controller number was set to aftertouch value instead.
gig Engine: Fixed handling of "smartmidi" dimension, which
was recognized as "unknown" dimension.
Fixed script function gig_set_dim_zone(): was accessing
ls_instr_script command line tool: is now not limited to
core language scripts, but can now also parse sampler format
dependent instrument scripts, with the respective specific

ScriptVM: Fixed runtime behavior of "and" and "or" binary
script expressions, which also evaluated the right hand side
of the expression even if the left hand side already failed
the overall expression semantic to become true.

used so far).
Gig Engine: Fixed support for 'aftertouch' attenuation controller.
Bumped version (1.0.0.svn39).

show them right to the current command line immediately while typing
(no double tab required for this feature, as it would be the case in
LSCP shell: fixed sluggish behavior when doing tab auto complete
LSCP shell: fixed conflicting behavior between keyboard input and
LSCP server evaluation result, that caused an inconsistent screen
output (keybord input is now never printed directly on screen, only
the result returned from LSCP server)
* LSCP Server: Fixed bug in LSCP grammar definition which caused a
statement like "GET SERVER INFOasdf\n" to be accepted as valid
statement (was so far practically irrelevant, however it caused
problems with the following new LSCP shell's auto completion
LSCP shell: improvement of auto completion feature, which now
not only resolves the next LSCP command token, but the longest,
unique sequence of LSCP commands expected next. Accordingly it
can now auto complete an entire line.

obvious and trivial LSCP syntax mistakes, support for
auto-completion by tab key and visual completion suggestion
Bumped version (1.0.0.svn29).
* WIP: Introducing the LSCP shell: for now, providing color
highlighting while typing (indicating correct part bold white,
incorrect part red, and turning green when the command is
complete. The shell application is implemented as thin client,
that is the parser work is performed on sampler side and the
shell application is just providing output formatting.
Bumped version (1.0.0.svn28).
* JACK audio driver: return JACK server's current sample rate
as default value for audio device parameter "SAMPLERATE"

on some recent compilers).
* Added support for multiple MIDI input ports per sampler channel (added
various new C++ API methods for this new feature/design, old C++ API
methods are now marked as deprecated but should still provide full
behavior backward compatibility).
LSCP Network interface: Added the following new LSCP commands for the new
feature mentioned above: "ADD CHANNEL MIDI_INPUT",
"REMOVE CHANNEL MIDI_INPUT" and "LIST CHANNEL MIDI_INPUTS". As with the
C++ API changes, the old LSCP commands for MIDI input management are now
marked as deprecated, but are still there and should provide full behavior

max. 100 audio channels) for most audio drivers
* minor code refactoring of win32 Condition code
preparations for release 0.5.1

* seems mingw has problems with accessing static variables from another
static (noinst) libtool library, at least it prevented it from producing
the liblinuxsampler.dll and just created a static archive
fixed Perl script which automatically updates our LSCP spec source file
(lscp.xml), it didn't remove multi line C++ code
* Added support for monitoring the total number of active disk streams
(new LSCP commands: GET TOTAL_STREAM_COUNT,

within apostrophes as well
* win32 port, work in progress:
added MME MIDI Input driver
changed return type of getSample() from int to int32_t

since this function is currently only used in the stream's
qsort() compare function, it did trigger any bugs
cubic interpolation now works in 24bit mode too
faster method to read 24bit words on little endian machines (x86):
replaced 3 byte reads + shifts with a 1 unaligned 32bit read and shift

added autoconf check for pthread bug found on certain NPTL-enabled
glibc versions (see Gentoo bug report #194076)

- global.h now only covers global definitions that are needed for the C++
API header files, all implementation internal global definitions are now
- atomic.h is not exposed to the C++ API anymore (replaced the references
in SynchronizedConfig.h for this with local definitions)

which caused all subsequent command line switches to be ignored
the default location of the instruments DB file can now be overridden
with ./configure --enable-default-instruments-db-location=/foo/bar.db
instruments DB feature can be disabled at compile time with
./configure --disable-instruments-db (i.e. for cross compilation)

plugin directory is not empty (fixes bug #54)
* added highly experimental code for synchronizing instrument editors
hosted in the sampler's process to safely edit instruments while playing
without a crash (hopefully) by either suspending single regions wherever
possible or - if unavoidable - whole engine(s)
disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
instead of fix values
removed legacy Makefiles in meanwhile deleted src/lib directory and its
bumped version to 0.4.0.7cvs
* minor assembly fix in x86 features detection (don't use the PIC
register, to avoid relocations in the text segment at runtime)
* A notification event is now sent when the
instrument loading on a sampler channel failed
* added default min and max values to restrict the number of allowed
audio output channels and MIDI input ports
the connection to the PCM interface is now closed when destroying
an audio output device
* ensure that a notification event is sent when already
loaded instrument is assigned to another sampler channel

altering the ALSA_SEQ_BINDINGS parameter.
Introduced a NONE keyword for unsubscribing from all bindings
(e.g. SET MIDI_INPUT_PORT_PARAMETER 0 0 ALSA_SEQ_BINDINGS=NONE).

* LSCP server returns verbose syntax errors (line and column where
syntax error occured, the unexpected character and the actually
expected, possible character(s), the latter only if less than 5
* fixed some minor memory leaks
* filename arguments in LSCP commands now allow to use escape
sequences, that is directly literal as one of: \', \", \\, \n, \r,
\f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
code value like \xf2) (fixes bug #24)
parser now supports extended ASCII character set
(up to ASCII code 255, i.e. includes now umlauts and accents)
LSCP parser C++ files are now automatically regenerated when
yacc input source file (lscp.y) was modified
* fixed compile time error for old Bison versions
(i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
* minor fix in our automatic stack trace mechanism on crashes, the
main process did not wait for the stack trace process to finish
and thus killed the whole application before the stack trace was
completely shown on the console
* small fix for previous Thread change: don't try to change static
priority for non-RT threads
* fixed several issues in fundamental "Thread" class: set scheduling
policy and priority on thread level, set a minimum stack size for
thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
threads simply inherited properties of starting thread instead of
setting their own policy and priority
updated and fixed test cases (haven't been touched in a while, but
are now all running successfully through all cases)
* minor Debian packaging fix: abort package build process when
Makefile.cvs failed (only relevant to CVS versions of LS)

need to have bison (or another yacc-compatible parser generator)
installed to be able to compile LS from CVS
* added highly experimental support for on-the-fly instrument editing
within the sampler's process (by using instrument editor plugins),
you'll notice the new "Registered instrument editors:" message on
startup, the plugin path can be overridden at compile time with
added a new LSCP command "EDIT INSTRUMENT <sampler-channel>" to spawn
a matching instrument editor for the instrument on the given sampler
channel (LSCP command syntax might be subject to change soon)
config.h is not going to be installed along with liblinuxsampler's
API header files anymore (not necessary anymore)
take care of $(DESTDIR) when creating the instruments DB on 'make
install' rule (needed for packaging and cross compilation)

(patch by Toshi Nagata)
* fixed some more EG bugs that could cause noises or crashes
* Added new field - DEFAULT to the
GET MIDI_INSTRUMENT_MAP INFO command response
* Added new LSCP command - SET FX_SEND NAME
The default map is now the first available map
* Implemented new, improved notification system
* Added new notification events for tracking
effect send changes and global volume changes
* the ALSA audio output driver parameters now reflect the correct
parameter value ranges for the respective selected sound card
(patch by Till Wimmer, a bit fixed and extended)
bumped version to 0.4.0.4cvs
* by default now all "MAP MIDI_INSTRUMENT" LSCP commands (also the
"PERSISTENT" ones) block until the respective mapping is completely
established in the sampler, added a new argument though to allow
explicit mapping in the background ("MAP MIDI_INSTRUMENT NON_MODAL")
LSCP documentation updated
* EG fine tuning: when attack is zero the EG starts at a level above
max sustain level, which means that there is a decay phase even if
sustain is 100%
* for now just set all notes off when receiving a MIDI coarse tuning
message to prevent hanging notes when transposing while playing
* handle MIDI coarse tuning messages (MIDI RPN #0 MSB, #2 LSB),
currently lazy implementation, transpose value is simply added on the
note on/off values instead only at the mandatory places, thus when
altering transpose while playing, voices can unintendedly survive
* bugfix: sampler crashed when trying to persistently map a not existent or
corrupt .gig file ("MAP MIDI_INSTRUMENT ... PERSISTENT")
behavior fix: reset FX send levels i.e. when receiving a MIDI "reset all
bumped version to 0.4.0.3cvs
* EG fix: a release value of zero could cause noises or crash
fix of previous thread safety fix, which in some cases locked the
* playback is no longer disabled during instrument loading
all notes playing on a channel that changes its instrument keep
playing with the old instrument until they get a note off command
new thread safety fix for lscp "load engine" and "set channel audio
* bugfix regarding FX Sends: when more than one sampler channel used FX
sends, only the audio signal of the last sampler channel made it into the
final output signal
fixed small autoconf compilation issue on certain systems (complained
about missing AM_PATH_ARTS macro)
* extended response of LSCP command "GET FX_SEND INFO" to return the FX
Send's MIDI controller and current send level and added two new LSCP
commands "SET FX_SEND MIDI_CONTROLLER" and "SET FX_SEND LEVEL"
* create IDs for FX Send entities in a logical sequence on a per sampler
* Fixed a memory leak due to EngineFactory::Destroy() not doing it
as an actual destructor and just removing the engine instance from
factory stock and all instances allocated via EngineFactory::Create()
never got delete'd and thus their destructors never called. This bug
was evident while having many mapped instruments and querying the
instrument status via GET MIDI_INSTRUMENT INFO command, eating up
system memory very quickly and never let it go.
* further bugfixes regarding MIDI instrument LSCP commands
("LIST MIDI_INSTRUMENTS ALL" reflected same bug as the
previously fixed "LIST MIDI_INSTRUMENTS" command and
"GET MIDI_INSTRUMENT_MAP INFO" result was not
terminated by a "." line)
* delete all MIDI instrument maps when a sampler-reset is issued
(i.e. on a "RESET" LSCP command)
* bugfix: LSCP command "LIST MIDI_INSTRUMENTS" returned wrong bank number
* global volume can now be altered at runtime
(added two new LSCP commands for this, LSCP specs updated)
* fixed noise which occured while using effect sends
* implemented effect sends (also added new LSCP commands for this feature,
updated LSCP spec document along with this commit batch as well)
* bugfix: sampler was limited to load max. 200 instruments in the
background (replaced RingBuffer FIFO by a std::list FIFO)
* Added new notification events for tracking audio/MIDI device changes,
MIDI instrument map changes and MIDI instrument changes
* fixed bug on adding MIDI instrument maps
* revised and extended MIDI instrument mapping feature to allow managing
arbitrary amount of maps and assigning each sampler channel individually
to one map (this commit batch includes LSCP spec document update and
respective implementation on LS side)
* fixed crash occuring in conjunction with the new 'MAP MIDI_INSTRUMENT'
LSCP command (cause: RingBuffer was not able to do deep copies)
* fixed crash occurring on certain LSCP scripts (Bug 39)
* store volume for each MIDI instrument mapper entry individually instead
of managing the volume as shared setting with the respective instrument
entry of its InstrumentManager
* if a filter is used and EG2 finishes before EG1, let the voice die
when EG2 has finished (this fixes a problem with clicks and voice
starvation for some gigs)
* implemented MIDI instrument mapping according to latest LSCP draft
* updated LSCP specification: added new command set for
managing MIDI instrument mappings, bumped LSCP spec
version to v1.2
(not implemented on server side yet)
* preparations for release 0.4.0
* fixed mutex initialization bug
* fixed crash when instrument loading failed previously on the same
sampler channel (fixes bug #36)
* small fix of LFO1 behaviour (dampening from max volume instead of
amplifying from 0)
added checks for bad MIDI data
* little configure.in fix for PPC
(patch by Ebrahim Mayat)
* The engine names are again encapsulated
into apostrophes as is said in the specification
* Commands returned by LinuxSampler in echo mode
are now terminated with <CR><LF> instead of <LF>
* MIDI driver API extension for MIDI drivers which already supply exact
time stamps for events (i.e. for offline rendering based MIDI drivers)
* real support for 24 bit samples - samples are not truncated to 16
support for aftertouch (channel pressure, not polyphonic aftertouch)
* src/Sampler.h, src/Sampler.cpp: allow 3rd party applications to
retrieve available drivers and sampler engines
src/linuxsampler.cpp: show available engines on startup (on the console)
* various fixes to allow liblinuxsampler to be used
(as a native C++ library)
* new filter implementation, which is more accurate and supports all
filter types including bandreject and lowpass turbo
* packaging changes:
- changed deprecated copyright attribute to license; added ldconfig
to post-(un)install steps; added devel package for liblinuxsampler;
to linuxsampler.spec (RPM)
* gcc 4.1 compilation fix
* sample loop parameters are now taken from the DimensionRegion
instead of the wave chunk
fixed keyswitching for v3 gigs with a number of keyswitch splits not
equal to a power of two
* added compile time options to allow disabling the various audio and MIDI
drivers (./configure --disable-foo-driver)
* added synthesis benchmark for gig::Engine
* added compile time option to disable processing of All-Notes-Off
* more thread safety fixes: another fix for lscp "load engine" and
midi thread. Sysex midi protected against lscp. Instrument loader
thread protected against lscp thread.
* fixed concurrency problems between the main thread doing
lscp notifications and the lscp thread
bug fix: the LFOs were not properly initialized
* fixed some concurrency problems between the lscp thread and the
audio/midi threads for these commands: load engine, set channel
audio output device, set channel midi input device/port/channel and
remove channel. Thanks to Vincent Bongiorno for bug reports and
removed an autotools warning
fixed an iterator bug
minor code clean-ups
* added aRts audio output driver (by no means RT safe)
* fix of silly bug introduced in recent memory fix: all devices were
destroyed instead of just the one asked for in the Sampler::Destroy
* fixed some invalid iterator errors
* fixed some memory management errors
* added smoothing of volume changes caused by control change messages
fine tuning of the crossfade volume curve
* fixed global pan (CC10) which hasn't been working for a while
fine tuning of the curves for volume (CC7) and pan (CC10 and gig
added support for the "attenuation controller threshold" gig
* added linear interpolation of volume modulation inside a
subfragment; this prevents clicks during voice stealing. Can be
switched off with the --disable-interpolate-volume configure option.
* implemented portamento mode and solo mode (a.k.a 'mono mode'):
all modes can be altered via standard GM messages, that is CC5 for
altering portamento time, CC65 for enabling / disabling portamento
mode, CC126 for enabling solo mode and CC127 for disabling solo mode
fixed EG3 (pitch envelope) synthesis which was neutral all the time
configure.in: do not automatically pick optimized gcc flags if the user
already provided some on his own (as CXXFLAGS)
* bugfix in LSCP parser which was confused by space(s) within device
(e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
changed version to 0.3.3cvs
* src/common/optional.h: fixed '=' operator which did not return anything
* Bug-fixes: pitch changes larger than one octave didn't work. Looped
samples small enough to fit in RAM didn't work.
* minor EG fine tuning: attack time now has a minimum value to prevent
* fixed voice stealing - stolen voices weren't killed
* fixed the notification messages delay due to lack of
network activity (fixes bug #26)
* Filter tuning: calculation of cutoff frequency and bandwidth
improved. Removed use of "BasicBPFilter". Changed bandpass filter
from constant peak to constant skirt. Use gig parameter Resonance if
no resonance controller is set. Removed keyboard tracking influence
* EG fixes: the length of "attack hold" stage was wrong. Release stage
can now start before attack stage ends. Cancel release didn't work
when sustain was zero.
* fixed event handling bug which was introduced by the recent synthesis
optimizations (events were only processed for the first active voice)
added global volume attenuation of -9 dB (0.35f) to prevent clipping
which can be overridden with --enable-global-attenuation
* Added new LSCP commands: GET TOTAL_VOICE_COUNT,
GET TOTAL_VOICE_COUNT_MAX, SUBSCRIBE/UNSUBSCRIBE TOTAL_VOICE_COUNT
* Added support for sostenuto pedal
* src/drivers/MidiInputPort.cpp: fixed legacy SysEx code which caused
dispatching of MIDI SysEx messages several times instead of once
src/engines/gig/Engine.cpp: fixed bug in SysEx handling
(patch by Juan Linietsky)
* synthesis core optimizations
* fixed endless loop which occured on MIDI control change
and pitch bend events
* bug fixes for the new EG implementation
* extensive synthesis optimization: reimplementation of EGs and LFO(s),
removed synthesis parameter prerendering and the synthesis parameter
matrix in general, splitting each audio fragment into subfragments now
where each subfragment uses constant synthesis parameters
(everything's still very buggy ATM)
* Added CHANNEL_INFO notification when engine is assigned to
sampler channel with no midi and audio device set (Fixes bug #22)
* improved filter cutoff calculation by adding support for the
following gig parameters: Cutoff freq (used when no cutoff
controller is defined), Control invert, Minimum cutoff, Velocity
curve and Velocity range. The keyboard tracking now also scales
cutoff frequency, not just resonance.
* fixed little inconsistency: LSCP commands 'LIST AVAILABLE_ENGINES' and
'GET CHANNEL INFO' returned different names for the gig::Engine,
returning now only 'GIG'
* Added configure option --enable-process-muted-channels
which can be used to enable the processing of muted channels
* Fixed app exit on Broken pipe error (Fixes bug #20)
* support for muting sampler channels and solo mode of the same, two new
LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
introduced for this (patch by Grigor Iliev, a bit adjusted)
* install necessary development header files for allowing 3rd party
applications to link against liblinuxsampler
liblinuxsampler's API documentation can be generated with 'make docs'
* fine tuning of the EG modulation parameters
* preparation for bugfix release 0.3.3
* if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
then simply show a warning about possible click sounds and reduce the
volume ramp down appropriately instead of cancelling the audio device
* minor efficiency fix (LFO preprocessing was performed even though the
respective LFO was disabled by the instrument patch)
* gcc 4.0 compilation fixes
* final preparations for bugfix release 0.3.2
* update MIDI channel info on program change
* don't reset volume, pan, pitch and MIDI controller values on instrument
or audio output device change
send 'CHANNEL_INFO' LSCP event on MIDI program change messages
* fixed minor issue with null/silence samples
(those stole voices even though they don't need a voice at all which
resulted in "voice stealing didn't work out" messages)
* fixed a key group bug which caused undefined behavior in conjunction with
stolen voices (this case was usually followed by a "killed voice
survived" or "voice stealing didn't work out" error message)
* added cmdline options for lscp address and port
* another voice stealing fix
(endless loop occured when voices were stolen from other engine channels)
* LSCP server: fixed LSCP event "CHANNEL_INFO" notification
(e.g. did not notify on volume changes)
* don't reset scale tuning on instrument or audio output device change
* fixed 'make dist' build rule to include all necessary files
* revised voice stealing (fixes crash caused by voice stealing)
* RPM .spec script added to repository.
* volume of release triggered samples now depends on note-on velocity,
note length and gig parameter "release trigger decay" instead of
* fixed some crashs in LSCP server
(patch by Grigor Iliev, fixes #19)
* hand-crafted assembly optimization code can be disabled with
'./configure --disable-asm' (definitely not recommended)
* support for the gig parameters for "release velocity response"
curves, which means the decay and release times now depends on
velocity. The softer velocity, the longer release.
fine tuning of the envelope curves. Decay1 and release now have two
parts, first linear and then exponential at the end.
* updated autotools build files for conditional compilation of CoreMIDI
(OS X) and MidiShare (Linux, OS X, Windows) drivers
* multiport and control file fixes
* altered and fixed debian packaging

* (re)implemented voice stealing algorithm "oldestvoiceonkey" and made it
the default voice stealing algorithm
added new LSCP command "GET SERVER INFO" which currently returns
description and version about this sampler
added some API documentation comments
* Little LSCP API change: renamed events "CHANNELS" -> "CHANNEL_COUNT" and
"INFO" -> "CHANNEL_INFO" to be more meaningful (patch by Grigor Iliev).
* tiny fix in LSCP parser; returned prefix "Err" instead of "ERR" on syntax
errors (patch by Grigor Iliev)
* All compile time options are now centrally alterable as arguments to the
./configure script. All options are C Macros beginning with CONFIG_
prefix and will be placed into auto generated config.h file.
* Implemented MIDI program change as general, engine independant solution.
The program number will determine the sampler channel to which the MIDI
device will be connected to and the given MIDI channel defines on which
MIDI channel that sampler channel should listen to. Also the program
change will disconnect probably established connection from the previous
program change event.
* ALSA driver: fix of previous ALSA fix ;-)
* [bug #9] Fixed for a LSCP command syntax convention
consistency, regarding the enumeration of available
sampler engines, Audio and MIDI drivers; this has
affected the semantics of the following commands:
which are now returning an integer count of engines
and drivers, respectively, while the following
new commands are now being introduced:
taking on the previous functionality, returning
a comma separated list of names.
LinuxSampler version bumped to 0.3.1.
* implemented progress indicator for loading instruments
(can be polled with "GET CHANNEL INFO", field "INSTRUMENT_STATUS")
* ALSA audio driver: don't block when trying to create audio device
* autotools build fixes for PPC architecture
* removed statically included libgig sources from the LinuxSampler code
base - you now have to compile and install libgig separately
added -Wreturn-type gcc switch to avoid bugs with no returns on non void
functions in future
* updated unit tests
* little correction in LSCP specification document (patch by Grigor Iliev)
* fixed bug in MMX/SSE(1) implementation of the sample loop code (caused
RAM-only voices to crash when entering the sample's loop section under

the ALSA sequencer ID of a port (read only)
* fixed segmentation fault on "GET CHANNEL INFO" commands which occured
when an engine type was selected but no audio device connected yet to
the sampler channel (fixes bug #4)
* fixed event leak (events sent to inactive keys were not freed)
implemented MIDI channel mode messages "All Sound Off", "Reset All
Controller", "All Notes Off" (fixes bug #5)
* fixed another crash under heavy load which was accidently introduced with
the previous commit - events have to be processed completely on all
engine channels before audio is rendered (fixes bug #7)
* spawning layered voices now within a loop instead of recursively (fixes
segmentation fault under heavy voice count load and reduces stress on the
voice stealing operates on all engine channels now
limit voice stealing to MAX_AUDIO_VOICES thefts per audio fragment cycle
fixed keygroup handling (layered voices could kill each other)

implemented MIDI Control Change 10 (Panpot)
* fixed some segfaults (which occured on EngineChannel destruction)
InstrumentResourceManager: recache small samples if their current
number of silence sample points are not sufficient enough for the used
audio output device
src/linuxsampler.cpp: voice / streams statistics on the console is back
again (can be turned on with command line switch --statistics)
* fixed a bug in the low-level thread synchronizing code, that made
loading of very small gig files sometimes fail
* gig::Engine: fixed silence (engine channels' events were not imported
into the engine, fixed undesired creation of new gig::Engine instances
(and disk threads)
AudioOutputDevice: reverted behavior to render per Engine instance (and
not per EngineChannel instance)
* design change: using now one sampler engine instance and one disk thread
instance for all sampler channels that are connected to the same audio
output device (and are using the same engine type of course)
added EngineFactory / EngineChannelFactory to remove the annoying build
dependencies e.g. of the lscpserver to the actual sampler engine
bumped version to 0.3.0 (current CVS state is still quite broken,
previous, stable CVS version was tagged as "v0_2_0" and is also available
as source tarball)

* fixed a bug that caused noise at end of samples
* fixed possibility that memory got not locked
immediately set instrument status when calling LOAD INSTUMENT NON_MODAL
* fixed segfault and freeze of LSCPInstrumentLoader thread
* lscpserver: we now only use one instrument loader thread; commands for
loading instruments in the background wait in a queue to be processed one
by one to avoid possible race conditions and to improve I/O efficiency
fixed possible race condition while streaming with multiple disk threads
by using an own decompression buffer for each disk thread
libgig: fixed some memory leaks caused by non virtual base constructors
* small fix for building with old JACK versions (0.94 and earlier)
* updated spec for INSTRUMENT_NAME
* Added INSTRUMENT_NAME to GET CHANNEL INFO command result set

used to assign an arbitrary name to the JACK client, it's now possible to
create multiple JACK audio output devices simultaniously for LS
src/network/lscpserver.cpp: fixed little bug in
'SET CHANNEL AUDIO_OUTPUT_CHANNEL' (altering of audio routing)
implementation, cleanup of error messages

occasionally, caused by random biquad parameters which lead to unstable
filter equation and thus to infinit filter output results)

(patch by Andreas Persson)
* libgig: fixed vcf_type_lowpassturbo value, fixed crossfade points order
gig::Voice: fixed special crossfade case 0,0,0,0 which actually means no
* Fix for a core. SET CHANNEL AUDIO_OUTPUT_CHANNEL needs
to check if audio output device exists.

without multiplying it by 10.
* Fix a basic diskthread multichannel issue.
* Initialize the synthesis mode bitmask properly
* Fixed bug with mixed channel creation
* fixed endless loop at the end of sample playback
(patch by Andreas Persson)

for the current synthesis case in the main synthesis loop
support for MMX and SSE(1) in the core synthesis algorithms (CPU feature
detection at runtime, only x86 so far)
* introduced 'synthesis mode' to reduce the amount of code and conditionals
for the current synthesis case in the main synthesis loop
support for MMX and SSE(1) in the core synthesis algorithms (CPU feature
detection at runtime, only x86 so far)

offsets are truncated to 32 bit, 24 bit samples are truncated to 16 bit
and additional articulation informations are ignored at the moment
(patch by Andreas Persson)
* libgig: applied patch by Andreas Persson which improves accuracy of all
three velocity response curves

differentiation if event might happened before or after current fragment
* applied patch from James Klicman which fixes some issues in configure.in

* configure.in: added check for UNIX98 compatibility, check if there's at
least one supported MIDI input and audio output system available, added
conditionals for ALSA and JACK

respectively if they're supported by the system
MidiInputDeviceFactory.cpp, AudioOutputDeviceFactory.cpp: little
workaround for reported linker problem

from signed 7 bit to signed 8 bit)
src/linuxsampler.cpp: stacktrace is now automatically shown on fatal
errors (that is segmentation faults, etc.), gdb should be installed for
this to work
gig::Voice: tiny accuracy fix of pan calculation
replaced old pool classes by completely new ones which now offer
* gcc-c++ 3.4.1 compability fixes.
* Fixed a hang in stage_fadeout
* fixed another bug in EGADSR which caused clicks when voices were killed
near the audio fragment end
* changed curve type from exponential to linear in stage 'end' of
EGADSR (fixes click sounds at the end of voices)
* added first two experimental voice stealing algorithms ('oldestkey' -
which just steals the oldest voice on the oldest key and 'keymask' - which
tries to pick the oldest voice on the same key where the new voice should
be spawned, if it fails it behaves like 'oldestkey'), the desired algorithm
can be selected at compile time (see Engine.h) will be configurable via
LSCP soon though
* Small fix to pan coeff. calculation.
(LS was silent with gigs where pan was 0).
* support patch panorama info
* added support for scale tuning via MIDI GS system exclusive message

spawned when a key was released)
libgig: bugfix in dimension region switching

MIDI controller values into account
* src/network/lscp.y: fixed symbol 'midi_input_channel_index' to allow
keyword 'ALL' for the respective LSCP commands
* ALSA audio driver: bugfix in device parameter 'CARD' which caused an
error message if used in conjunction with 'CREATE AUDIO_OUTPUT_DEVICE'
JACK audio driver: fixed minor JACK port name issue and the device was
not activated by default on creation which caused it to render solely

binary fields, spuriously created new elements in maps while trying to
find map members)

"NAME" which now updates the registered ALSA seq port name as well, fixed
port parameter "ALSA_SEQ_BINDINGS" to allow more than one binding
src/network/lscp.y: fixed symbol STRINGVAL (that is strings encapsulated
into apostrophes) which didn't allow space characters
changed all driver names and driver paramaters to upper case
fixed typo in LSCP documentation
(section 5.3.12, was: "SET MIDI_INPUT_PORT PARAMETER",
should be: "SET MIDI_INPUT_PORT_PARAMETER")
* completely removed the lex scanner and replaced it by pure yacc rules
for all terminal symbols (that is command keywords and variables) to
avoid misunderstandings while parsing (e.g. recognition of command
keywords in string arguments)
src/drivers/audio/AudioChannel.cpp: changed channel parameter 'Name' to
'NAME' as defined in the LSCP documentation
* src/drivers/DeviceParameter.cpp: fixed return values for
classes 'DeviceRuntimeParameterString' and 'DeviceCreationParameterString'

'DeviceCreationParameterString' and 'DeviceCreationParameterStrings'
which returned the default value(s) not encapsulated into apostrophes
src/network/lscpserver.cpp: fixed implementation of LSCP commands
"GET MIDI_INPUT_DRIVER_PARAMETER INFO" and
"GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO"
* src/linuxsampler.cpp: tidied up a bit, "initialization completed"
message shown only after the server is actually running
src/testcases/: print the name of each test suite before running the
tests of the suite, added first tests against the LSCP server using a
socket connection to the LSCP server (tests for the following LSCP
commands: "ADD CHANNEL", "GET CHANNELS", "REMOVE CHANNEL")
* implemented "SET ECHO" LSCP command
* src/Sampler.cpp: changed sampler channel index allocation from consistent
channel index allocation to incrementing channel index allocation, that is
it doesn't fill channel index gaps anymore (to avoid race conditions)
implemented "LIST CHANNELS" LSCP command
* src/linuxsampler.cpp: print out LinuxSampler version and show all
registered MIDI input drivers
renamed class 'InputOutputDevice' -> 'Device'
* moved directory '/src/audiodriver' -> '/src/drivers/audio'
moved directory '/src/mididriver' -> '/src/drivers/midi'
* Get rid of the timeout on select()
* GET MIDI_INPUT_PORT_PARAMETER INFO command
* Added MISCELLANEOUS event to help debugging client/server
interaction. It spits out every line received by the server.
* Reworked the infrastructure to allow for parameter
registration and creation
Changed alsa audio output and midi drivers
to work with new infrastructure
* moved ToString to common
Implemented handling of multiple connections
Implemented guts for event subscription/unsubscription
Illustrated event notification sending by sending MISC events
when connections are established or terminated.
* Do not use accessor operator for the map unless
the element accessed already exists
* Small enhancement to mutex class to support Trylock()
* Unconsolidaded MIDI input related channel commands are back:
SET CHANNEL MIDI_INPUT_DEVICE <chan> <midi-device>
SET CHANNEL MIDI_INPUT_PORT <chan> <midi-port>
SET CHANNEL MIDI_INPUT_CHANNEL <chan> <midi-chan>
Still useful for compability with legacy clients, an almost
deprecated command gets re-implemented:
SET CHANNEL MIDI_INPUT_TYPE <chan> <midi-driver>
Optional parameter list on MIDI input device creation fixed,
but not quite fully effective yet:
CREATE MIDI_INPUT_DEVICE <midi-driver> [<key>=<val>...]
* Removed/cleaned up some left over stuff
Fixed midi port name parameter (no longer static)
* Updated parser, lscp server and sampler class for new MIDI_INPUT
Minor fixes (and major new bugs) here and there
Consolidated 3 SET CHANNEL MIDI_xxx commands into one:
SET CHANNEL MIDI_INPUT
* Fixed object deletion
* Updated MIDI infrastructure similar to what was previously
done with the AUDIO
Implemented Alsa driver using new infrastructure
TODO: MacOS drivers!
* added directory 'Documentation'
network protocol document now under CVS, converted from latest document
into XML (Documentation/lscp.xml), lscp.xml is compliant to RFC 2629 and
can be converted into HTML or RFC common ASCII format by using 'xml2rfc'
* SET CHANNEL AUDIO_OUTPUT_TYPE <chan> <driver> command is back!
creates an audio output device instance of the given driver type
('Jack' or 'Alsa') with default parameters if none exists,
otherwise it just picks the first available device and assign
it to the intended sampler channel.
The AudioOutputDevice class get's a new pure virtual method,
Driver(), which is implemented on both of the existing inherited
classes, AudioOutputDeviceAlsa and AudioOutputDeviceJack, with
the sole purpose to return the driver type name as a String
('Alsa' and 'Jack', respectively).
The quoting on the filename argument for the LOAD INSTRUMENT
command has been made optional; you can have both ways, with
single quotes or none, keeping compability with older LSCP
An additional sanity check is made on LOAD INSTRUMENT, whether
the sampler channel has an audio output device assigned, thus
preventing the server from crashing on instrument file load.
The GET AUDIO_OUTPUT_DEVICE INFO now includes the missing
'driver' item, as predicted by the draft protocol document.
* Added implementation for SET CHANNEL AUDIO_OUTPUT_DEVICE
* LOAD INSTRUMENT NON_MODAL
* Fixes and hacks to make CREATE AUDIO_OUTPUT_DEVICE work
* Fix for CREATE_AUDIO_OUTPUT_DEVICE with all default params
Fix for GET AUDIO_OUTPUT_DEVICES resultset
Support for BACKGROUND loading
* Changed LSCPServer::LoadInstrument() signature, which adds a new
boolean argument (bool bBackground) where the loading mode maybe
selected, whether modal (the default), or modeless (in background).
* Update audiodriver to supply parameters in compliance
with the latest LSCP spec
* Update parser to comply with the latest spec
* small but important typo fix in optional.h
* Load Instrument patch applied; this patch makes the
LOAD INSTRUMENT command to return immediately,
almost/always with an OK response, while spawning
the proper instrument file loading in the background.
New INSTRUMENT_STATUS field on GET CHANNEL INFO result
set; the instrument status value holds the load progress
percentage if positive, otherwise a negative value is
evidence of a load exception error.
VERSION is now set to 0.2.
* Remove calls to pure virtual from constructor of base class
to avoid runtime failure. InitWithDefault() will have to be called
from the constructor of the class where virtuals are implemented.
* src/common: added template class 'optional<>' which can be used e.g. as
return type whenever a value might be returned, but don't has to; this
template class pretty much acts like a pointer of the given type, but is
much more safer than a simple pointer
src/audiodriver: added static class AudioDeviceFactory to create audio
devices at runtime by using a string and to obtain driver informations
of drivers at runtime, driver classes should simply use the macro
REGISTER_AUDIO_OUTPUT_DRIVER(DriverName,DriverClass) in their cpp file
to register the driver to LinuxSampler (no changes needed anymore in the
LS code to add a new audio output driver)
src/drivers: added classes to dynamically manage driver parameters; there
are two different kinds of parameters: parameters which are need to
create a new device (DeviceCreationParameterX) used to e.g. create an
audio output device or a MIDI input device and parameters which are only
available at runtime, means when a device is already created
(DeviceRuntimeParameterX) which will be e.g. used as audio channel
parameters and MIDI port parameters
src/linuxsampler.cpp: all registered audio output drivers will be shown
on the console on startup
src/network: implemented configuration of audio output devices via LSCP
* Error handling in resultset class, rewrite lscpserver to use resultset.
* Added LSCP command GET CHANNEL INFO
* Added methods for CHANNEL_INFO command
* LSCP allows now comment lines, that is lines starting with a hash ('#')
src/engines/gig/Voice.cpp: fixed "SET CHANNEL VOLUME" bug
* Do polynomial interpolation computation in float
* src/engines/gig/Voice.h: fixed bug which caused to hear only one audio
* Correct KeyOn with velocity = O bug
* New type_core_midi and type_midishare types
* First import of MidiShare device
* biquad filter parameters are now calculated outside the interpolate
loop for better performance
couple of loop unroll optimizations
filter is now enabled by default
cubic interpolation is now enabled by default
reduced debug level to 1 to lower verbosity
raised default limit for voices to 128
raised default limit for streams to 150
added some compiler optimization flags (-ffast-math -march -mcpu)
* Fixed SET CHANNEL MIDI_INPUT_CHANNEL lscp command.
* Adding LSCP command SET CHANNEL MIDI_INPUT_PORT. First attempt.
* src/audiodriver/AudioOutputDeviceJack.cpp: fixed another stupid bug that
caused a segmentation fault when the Jack audio driver was loaded
* src/Sampler.cpp: fixed 3 stupid but fatal bugs that left in the rush (in
method SamplerChannels(), CreateAudioOutputDevice() and
src/network/lscpserver.cpp: implemented LSCP command
'SET CHANNEL MIDI_INPUT_CHANNEL'
src/Sampler.h: moved enums 'audio_output_type_t', 'midi_input_type_t'
and 'engine_type_t' into the respective base classes
('AudioOutputDevice', 'MidiInputDevice', 'Engine')
* src/common/Thread.cpp: threads are now stoppable even if they are
waiting for a condition
src/common/Condition.cpp: fixed little misbehavior of Set() method,
which locked the Condition object on return
src/testcases: added a couple of new unit tests (against classes
'Mutex', 'Condition' and 'Thread')
* src/common/Thread.cpp: method StartThread() now blocks until thread
actually runs, mlockall() will only be applied for realtime threads
initiated automatic unit tests against the LinuxSampler codebase
(see src/testcases): already added a couple of tests for the Thread and
Mutex classes, you have to explicitly compile the unit tests by running
'make testcases' (you need to have cppunit installed though) and then you
can run the console version of the test runner by calling
src/Sampler.h: added API documentation
* completely restructured source tree
implemented multi channel support
implemented instrument manager, which controls sharing of instruments
between multiple sampler engines / sampler channels
created abstract classes 'AudioOutputDevice' and 'MidiInputDevice' for
convenient implementation of further audio output driver and MIDI input
driver for LinuxSampler
implemented following LSCP commands: 'SET CHANNEL MIDI INPUT TYPE',
'LOAD ENGINE', 'GET CHANNELS', 'ADD CHANNEL', 'REMOVE CHANNEL',
'SET CHANNEL AUDIO OUTPUT TYPE'
temporarily removed all command line options
LSCP server is now launched by default
* Fixed bug in AskForCreatedStream(). Cored if stream was not created.
* added Envelope Generator 2 and 3 (filter cutoff EG and pitch EG) for
accurate .gig playback
fixed accuracy of pitch calculation
changed filter cutoff range to 100Hz..10kHz with exponential curve, this
value range can also be adjusted on compile time by setting
FILTER_CUTOFF_MIN and FILTER_CUTOFF_MAX in src/voice.h to desired
src/lfo.h: lfo is now generalized to a C++ template, which will be useful
especially when we implement further engines
* implemented all three low frequency oscillators (LFO1 = volume,
LFO2 = filter cutoff frequency, LFO3 = pitch) for accurate .gig playback
* added filters (lowpass, bandpass and highpass), note that filter code is
currently disabled by default, you have to explicitly enable it in
src/voice.h by setting define ENABLE_FILTER to 1
src/eg_vca.cpp: Decay_1 stage now using exponential curve
* src/eg_vca.cpp: added following transitions to the envelope generator:
'Attack_Hold' -> 'Release', 'Decay_1' -> 'Release' in case of a release
EG1 parameters 'Attack Time', 'Release Time' and 'Sustain Time' are now
controllable by a MIDI controller defined in the .gig file
src/voice.cpp: fixed bug in pitch calculation which caused new triggered
voices to be played back without honoring the current pitch bend value
* implemented parser for the LinuxSampler control protocol (LSCP) by using
flex / bison (where src/network/lscp.l is the input file for lex / flex
and src/network/lscp.y is the input file for yacc / bison), parser and
scanner can be regenerated by 'make parser'
implemented LSCP network server (only single threaded so far), LSCP
server will be launched if LinuxSampler was started with "--server" flag,
implemented the following LSCP commands so far: "LOAD INSTRUMENT", "GET
CHANNEL VOICE_COUNT", "GET CHANNEL STREAM_COUNT", "GET CHANNEL
BUFFER_FILL", "SET CHANNEL VOLUME" and "RESET CHANNEL"
disk thread now started within the engine
* implemented bidirectional voice state transition, means voice state can
switch arbitrary times between 'Sustained'<-->'Released' within it's life
time, thus the release process of a voice can be cancelled
src/eg_vca.cpp: extended envelope generator by additional states
('Attack_Hold', 'Decay_1' and 'Decay_2')
applied patch from Vladimir Senkov which adds new command line parameters
('--jackout', '--alsaout' and '--samplerate')
configure.in: fixed compiler warning
* introduced time stamped events
implemented jitter correction
added pitchbend wheel support
src/audiothread.cpp: using voice pool instead of a voice array, makes
voice allocation more efficient and code more readable
src/rtelmemorypool: redesigned, added some new methods and pool is now
derived from list
* Added JACK support: Audio rendering process is now callback based and
independant of used audio output system. Interfaces to other audio output
systems can be added by creating a class derived from abstract base class
'AudioIO' and embedding the new class into linuxsampler.cpp.
src/audiothread.cpp: applied patch from Vladimir Senkov which fixes
hanging notes in conjunction with the sustain pedal
* implemented amplitude envelope generator
src/voice.cpp: some .gig instruments still sounded detuned, I hope
finally to have this fixed now
* src/gig.cpp: fixed looping informations ('LoopStart', 'LoopEnd' and
src/voice.cpp: pitch sample according to keyboard position only if
keyrange > 1 key, this was the reason that some gig files were horrible
src/audioio.cpp: bigendian specific fix
src/ringbuffer.h: removed kernel header dependency by adding own atomic.h
* implemented looping; RAM only loops (that is loops that end within the
cached part of the sample) are handled in src/voice.cpp whereas
disk stream looping is handled in src/stream.cpp and is mostly covered
there by the new ReadAndLoop() method in class 'Sample' from src/gig.cpp
* added command line switch --volume to set the global volume level
added command line switch --inputclient to connect to an Alsa sequencer
input client on startup (e.g. a MIDI port with a keyboard)
added command line switch --instrument to select an instrument in case
the instrument file provides more than one instrument
* src/audioio.cpp: added support for Alsa 1.0.0
src/audiothread.cpp: fixed several bugs in sustain pedal handling
src/diskthread.cpp: fixed several bugs which occured under extreme
conditions (endless loop in audiothread, freezing the whole application,
outage of available disk streams)
src/voice.cpp: fixed cubic interpolation (disabled by default; you can
enable it by setting USE_LINEAR_INTERPOLATION to 0 in src/voice.h)
src/configure.in: added check for Alsa version
* implemented velocity->volume mapping: samples are now played back with a
volume appropriate to the velocity of the triggered key, the velocity
curve transformation functions (in src/gig.h) used for this are so far
only an approximation to the ones from Gigasampler
* rewrote sustain pedal handling: instead of just queuing the note-offs I
added a sustain pointer for each midi key which starts to point to the
first active voice on the respective key and increments to the next voice
on the key when a note-off arrived, the release velocity value will
immediately be stored in the respective voice object (this also fixes the
segmentation fault issue when the sustain pool was full)
* src/voice.cpp: fixed bug which caused a voice not free it's disk stream
when the whole sample was already played back and the voice was going to
free itself resulting in outage of unused disk streams after a while
src/audioio.cpp: implemented automatic fallback to ALSA plughw when the
sound card doesn't support one of the hardware parameters
src/linuxsampler.cpp: solved segmentation fault issue when receiving a
SIGINT which was caused due to the fact that all threads entered the
signal handler (there still seems to occur a segfault on some certain
added print out of all-time maximum usage of voices and streams and the
current number of unused streams
src/thread.cpp: the StopThread() method will now block until the
associated thread actually stopped it's execution
* src/gig.cpp: fixed bug in decompression algorithm which caused it not to
detect the end of a stream and let the disk streams reload forever also
resulting in strange sounds at the end of disk voices (concerned only
playback of compressed gig files)
src/audiothread.cpp: deallocation of voices when they reached the end of
playback (thus e.g. when sustain pedal is pressed and a disk stream
reached it's end)
various endian corrections needed for non intel systems
introduced debug level, you can set the debug level and thus the
verbosity of LinuxSampler in src/global.h
* src/audiothread.cpp, src/audiothread.h: added Sustain Pedal support
implemented by postponing note-offs and leting multiple voices play
on the same MIDI key.
added the RTELMemoryPool Class which is a fast RT-safe memory allocator
and list manger
src/linuxsampler.cpp: added a voice and stream counter debug message
* transition from plain Makefile to autotools, source files moved to src/
configure.in: added test for x86 architecture
src/voice.h: x86 specific asm optimization for double to int casts only
if compiling for x86 architecture
