32
33 Version 3.3.0 (30 Jul 2009)
34

37 - fixes for building with Visual C++
38 - minor fix in configure for building DLL on Windows

76 Version 3.2.0 (14 Oct 2007)
77
78 * packaging changes:
79 - added Mac OSX XCode project files (patch by Toshi Nagata)

99 - fixed segmentation fault in the gig::File destructor sequence which
100 happened when gig::Group informations were accessed before

104 - added missing parameter initalizations in sample, region and
105 instrument constructors
106 - clear unused fields when saving samples and regions
107 - fixed write support bugs: v3 dimension limits and chunksize
108 weren't saved, leverage controller of type controlchange
109 couldn't be saved, group name list chunk was placed wrong,
110 dimension region chunks also placed wrong
111 - added initialization of some fixed info strings in file and
112 instrument
113 - write support: files created by libgig will now have the RIFF
114 chunks in correct order
115 - write support: two previously unknown fields in dimension
116 definition are now saved
117 - added constants for gig file versions

121 - write support: DLSID is now generated on the file and the
122 instruments
123 - write support: improved the default values for dimension region
124 parameters
125 - more write support fixes: crossfade parameters were not saved,
126 v3 dimension limits were not correctly initialized and saved
127 when dimensions were added or deleted, v3 wave pool offsets were
128 not saved correctly
129 - write support: 24 bit samples can now be written
130 - write support: version 3 is now the default for new files
131 - more write support fixes: the 3ewg chunk is now bigger for v3,
132 dimension regions without mapped samples are now allowed, 3gnl
133 list in v3 files now always has 128 entries, several parameters
134 where incorrectly saved due to an operator precedence mistake
135 - DeleteSample now removes all references to the deleted sample
136 - AddDimension now copies all parameters from existing dimension
137 regions and also makes sure that the samplechannel dimension is
138 placed first in the list of dimensions.
139 - added method GetParent() to class 'DimensionRegion', which returns its
140 parent Region
141 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
142 unused areas
143 - added various setter methods to DimensionRegion class which take care
144 of updating lookup tables / caches.
145

161 - custom velocity splits now works for gig v3 files too
162 - added support for custom splits points for other dimensions than
163 velocity (gig v3 feature)
164 - added "smart midi" and "round robin keyboard" dimensions
165 - added new method File::DeleteGroupOnly() which only deletes the given
166 group but moves all its members to another group, the other method,
167 that is File::DeleteGroup() now removes not just the group, but also
168 all the samples that belong to that group
169 - fixed crash which occured on interfering File::DeleteSample() and
170 File::GetNextSample() calls (due to iterator invalidation)
171 - fixed group names which were not saved
172 - fixed group destructor which did not remove the RIFF chunk associated
173 with the group
174 - added Instrument::MoveRegion method
175 - fixed constructor for Region, which did not initialize correctly
176 when used from Instrument::AddRegion
177 - when saving, override the gig::Regions sample reference simply by
178 the region's first dimension region's sample (avoids an exception
179 when trying to save a new instrument)
180 - fixed AddDimension() method which did not fill out all mandatory
181 dimension definition fields
182
183 * src/DLS.cpp, src/DLS.h:
184 - added Instrument::MoveRegion method

186 causing an exception when trying to save a new instrument
187
188 * src/RIFF.cpp, src/RIFF.h:

255 - added write support
256 - Chunk::LoadChunkData() can now be called again to resize the buffer
257 after a Chunk::Resize() and before the File::Save() call to allow

316 articulation informations are ignored at the moment
317 (patch by Andreas Persson)
318 - added some file format compatibility checks
319 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
320 never used, because the necessary check was made before

369
370 * packaging changes:
371 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
372 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
373 - fixed man pages automake install rule (which didn't work on Mandrake,
374 SuSE and Fedora)
375 - fixed generation of Doxygen API documentation (now also included in
376 RPM and Debian packages)
377
378 * src/gig.cpp, src/gig.h:
379 - fixed / improved accuracy of all three velocity to volume
380 transformation functions a.k.a. 'nonlinear','linear','special'
381 (patch by Andreas Persson)
382 - denormals are filtered from the velocity to volume tables
383 - bugfix for dimension region switching (wrong handling of the release
384 trigger dimension, no bit range check for dimensions of split type

406 - added libgig.spec and libgig.pc package configurations for generating
407 Redhat packages
408 - header files included on installation.
409 - autotools-generated files removed from CVS repository.
410 - added support for generating Debian packages
411 - version of shared library can be set in configure.in
412
413 Version 0.7.0 (3 May 2004)
414
415 * general changes:
416 - various big endian specific corrections
417 (successfully tested now on PPC)
418 - minor adjustments to avoid compile errors on some systems
419 (using now pow() instead of powl() and --pedantic g++ compiler switch)
420 - libtoolized the library
421 - added man pages for the command line tools
422 (gigextract, gigdump, dlsdump, rifftree)
423
424 * src/gig.cpp, src/gig.h:
425 - fixed bug in decompression algorithm which caused it not to detect
426 the end of a stream
427 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
428 takes the MIDI key velocity value as an argument and returns the
429 appropriate volume factor (0.0 ... 1.0) for the sample to be played
430 back, the velocity curve transformation functions used for this are
431 only an approximation so far
432 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
433 'Sample::LoopSize' which reflected wrong values
434 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
435 measured in sample points instead of byte offset
436 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
437 'Sample::FineTune'
438 - added class attribute 'Sample::LoopSize'
439 - added method GetInstrument(uint index) to class 'File'
440 - added ReadAndLoop() method to class 'Sample' which is an extension to
441 the normal Read() method to honor the sample's looping information
442 while streaming from disk
443 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
444 'eg2_ctrl_t': replaced this huge enumeration by a structure which
445 reflects the MIDI controller number in case of an ordinary control
446 change controller (this saves a huge switch-case block in the
447 application of the library user)
448 - renamed following attributes in class 'DimensionRegion':
449 'AttenuationContol' -> 'AttenuationController',
450 'InvertAttenuationControl' -> 'InvertAttenuationController',
451 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
452 - minor fix in API documentation for method GetVelocityAttenuation() in
453 class 'DimensionRegion'
454
455 * src/RIFF.cpp, src/RIFF.h:
456 - added additional API documentation
457 - minor fix in Chunk::Read() method (only a minor efficiency issue)
458
459 * src/gigdump.cpp:
460 - added printout of samples' looping informations
461
462 Version 0.6.0 (3 Nov 2003)
463
464 * initial release
