libgig Subversion History
* Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
destructors. Added new virtual method DeleteChunks() to those classes
for this which must be explicitly called instead to remove their RIFF
Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
of zero; which is unsafe per se.
Added C++11 "override" keyword where appropriate.
DLS.cpp, DLS.h: Added new abstract interface base class DLS::Storage
which is derived by the respective classes for implementing (the old)
UpdateChunks() and the new DeleteChunks() method.

Bumped version (4.0.0.svn6).
* Using now native integer size where appropriate.
Bumped version (4.0.0.svn5).

monolithic file, otherwise if .gig file is < 2 GB check for "extension"
files (.gx01, .gx02, ...) instead.
Bumped version (4.0.0.svn4).
* gig.cpp/.h: GIG FORMAT EXTENSION: Added support for saving gig file
larger than 4 GB as one single monolithic gig file. A new custom RIFF

from old ones which were splitted over several (.gx01, .gx02, ...)
"extension" files before.
DLS.cpp/.h: Sample class: wave pool offsets are now 64 bits (to allow
support for files larger than 4 GB).
RIFF.cpp/.h: Addded support for RIFF files larger than 4 GB, by default
the required internal RIFF file offset size is automatically detected
(that is RIFF files < 4 GB automatically use 32 bit offsets while
files >= 4 GB automatically use 64 bit offsets), a particular offset
size can be forced with a new option added to the RIFF File constructor
RIFF.cpp/.h: When saving a modified, grown RIFF file, the temporary file
size during Save() operation will no longer be larger than the final
grown file size.

files. Note that this might require manual adjustments to projects
linking statically against libgig
(see https://wiki.debian.org/ReleaseGoals/LAFileRemoval for details).

to avoid clash with definition in i.e. windows.h
* preparations for release 3.1.0
* src/gig.cpp, src/gig.h: fixed behavior regarding the newly added support
for sample groups, the initial implementation assumed a group index of 0
in the .gig file to mean "no group assigned" and thus the possibility
that there might not be a group at all, but in fact the .gig format
assumes always at least one group (the default group), thus a group index
of 0 means "member of default group"
* support for Gigasampler's sample groups added
* added DLS INFO string Subject and fixed string Media
fixed SamplePeriod calculation
* fixed and expanded initial test cases
* bugfix: sampler parameters UnityNote, FineTune, Gain, SamplerOptions and
SampleLoops were not stored when trying to save DLS or .gig files
* several fixes for the write support

of Gigasampler write support)
* src/gigdump.cpp: print global file informations

instead of the wave chunk
keyswitching dimension is changed from split type "normal" to "bit"
* added support for more than one custom velocity split inside a
* preparations for release 3.0.0
* fixed bug introduced in previous commit - info strings weren't
* fixed some memory management errors, one of them was causing a crash
when a multi-file gig was deallocated
* src/RIFF.cpp: bugfix in File::Save() methods which did not ensure that
the whole RIFF tree was already built before writing which caused opening
an existing file and saving it afterwards to write just an empty file
* recommited bugfixes regarding .gig write support
(that commit batch got lost due to the recent CVS server defect)
* src/gig.cpp, src/gig.h:
- added write support (highly experimental)
- removed unnecessary definitions from header file

src/gigdump.cpp: show correct amount of dimension regions instead of 32
(patch by James Wylder)
- further bugfixes regarding DLS write support
- show for every region the name of the referenced sample
- show file name in quotation marks
* bugfixes for the last commit batch
* src/RIFF.cpp, src/RIFF.h:
- Chunk::LoadChunkData() can now be called again to resize the buffer
after a Chunk::Resize() and before the File::Save() call to allow
placing the new data in the chunk's write buffer and perform the
resize and write operations in one rush
- fixed loading of Articulation Connections (<artl> list chunks were
seeked instead of ordinary <artl> data chunks)
- added write support (highly experimental)
* fixed write support in RIFF classes
* added write support (only to the RIFF classes yet)
* support for the gig v3 feature to have a number of dimension splits
not equal to a power of two

library units (RIFF,DLS,gig)
all tools now offer a command line switch -v to show the tools revision
and the used libgig version
man pages are now auto generated with the correct libgig version
* src/gig.h, src/gig.cpp: API change of progress callback

with Read() and ReadAndLoop() to avoid race conditions in case of
multiple streaming threads
fixed some memory leaks caused by non virtual base constructors
* fixed conditional linkage of either libsndfile or libaudiofile
(if none of the two exist, configure will abort)
* src/gig.cpp: Fixed mono decompression.
* src/gig.cpp, src/gig.h, src/gigextract.cpp: Support for compressed
mono samples. Experimental support for compressed 24 bit
samples. Fixes for decompression on big-endian CPUs. Fix for bug
that truncated end of compressed samples.
- another memory leak fix
- duplicated memory free fix
- tiny fix in decompression buffer reallocation
(patch by "Gene" a.k.a Anders Alm)

to their region(s) or dimension region(s) (patch by Andreas Persson)
* src/gig.cpp: fixed some memory leaks (patch by Gene Anders)
* src/gig.h, src/gig.cpp: support for up to 8 dimensions as introduced by
Gig V3 (patch by Andreas Persson)
* src/gig.cpp, src/gig.h:
- fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
never used, because the necessary check was made before initialization)
- fixed crossfade points order (structure for big endian and little
endian systems was interchanged)
* src/gigdump: added output of UnityNote and FineTune
* src/DLS.cpp, src/gig.cpp: experimental support for Gigasampler v3 format;
64 bit file offsets are truncated to 32 bit, 24 bit samples are truncated
to 16 bit and additional articulation informations are ignored at the
moment, added some file format compatibility checks
(patch by Andreas Persson)
* gig.h oneliner forward declaration of gig::Region.
Fixed man pages automake install rule.
Doxygen documentation fix (make docs).
* src/gig.cpp, src/gig.h: applied patch by Andreas Persson which improves
accuracy of all three velocity response curves
* src/gig.cpp, src/gig.h: added class attribute 'Layers' to class 'Region'
src/gigdump.cpp: replaced printout of DLS Region layer by printout of
amount of Gigasampler layers
* src/gig.cpp: fixed panorama value in DimensionRegion (invalid conversion
from signed 7 bit to signed 8 bit)
src/gigdump.cpp: added printout for panorama value for each
* bugfix for dimension region switching (wrong handling of the release
trigger dimension, no bit range check for dimensions of split type
* src/gigdump.cpp: added printout of crossfade definitions
* src/gig.h, src/gig.cpp: fixed / improved accuracy of all three velocity
to volume transformation functions (a.k.a. 'nonlinear','linear',
'special'), denormals are filtered from the velocity to volume tables

* added printout for dimension informations to the 'gigdump' tool
(amount, type, bits, zones)
* added support for libsndfile to the 'gigextract' tool
* renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
* added support for generating Debian packages
version of shared library can be set in configure.in
* packaging changes:
- added libgig.spec and libgig.pc package configurations.
- header files included on installation.
- autotools-generated files removed from CVS repository.

added man pages for the command line tools
(gigextract, gigdump, dlsdump, rifftree)
minor preparations for libgig release 0.7.0 (updated Changelog, etc.)
* src/gig.h: changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
'eg2_ctrl_t': replaced the huge enumeration by a structure which reflects
the MIDI controller number in case of an ordinary control change
controller (this saves a huge switch-case block in the application of the
src/gig.h: renamed following attributes in class 'DimensionRegion':
'AttenuationContol' -> 'AttenuationController',
'InvertAttenuationControl' -> 'InvertAttenuationController',
'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
src/gig.cpp: minor fix in API documentation for method
'GetVelocityAttenuation()' in class 'DimensionRegion'
* src/gig.cpp: attributes 'LoopStart', 'LoopEnd' and 'LoopSize' in class
'Sample' reflected wrong values
updated Make files (autoconf 2.58, automake 1.6.3)
* src/gig.cpp, src/gig.h: added ReadAndLoop() method to class 'Sample'
which is an extension to the normal Read() method to honor the sample's
looping information while streaming from disk
src/RIFF.cpp: minor fix in Chunk::Read() method (only a minor efficiency
src/gigdump.cpp: added printout of samples' looping informations
* gig.h, gig.cpp:
changes in class 'Sample':
- fixed loop attributes which reflected wrong values
- attributes 'LoopStart' and 'LoopEnd' are now measured in sample points
instead of byte offset
- renamed misleading attribute name 'MIDIPitchFraction' to 'FineTune'
- added attribute 'LoopSize'
changes in class 'File':
- added method GetInstrument(uint index)
* src/gig.cpp, src/gig.h: added method GetVelocityAttenuation() to class
DimensionRegion which takes the MIDI key velocity value as an argument
and returns the appropriate volume factor (0.0-1.0) for the sample to be
be played back, the velocity curve transformation functions used for this
are only an approximation so far
* src/gig.cpp: fixed bug in decompression algorithm which caused it not to
detect the end of a stream
various endian corrections (successfully tested now on ppc)
minor adjustments to avoid compile errors on some systems
(using now pow() instead of powl() and --pedantic g++ compiler switch)
src/RIFF.cpp, src/RIFF.h: added additional API documentation
