93
94 Version 3.2.0 (14 Oct 2007)
95
96 * packaging changes:
97 - added Mac OSX XCode project files (patch by Toshi Nagata)

107 lengths can be specified for each INFO chunk
108 - added Resource::GenerateDLSID function
109 - write support fix: allow regions without mapped samples
110 - added method SetKeyRange() to the Region class which should be used

122 - added missing parameter initalizations in sample, region and
123 instrument constructors
124 - clear unused fields when saving samples and regions
125 - fixed write support bugs: v3 dimension limits and chunksize
126 weren't saved, leverage controller of type controlchange
127 couldn't be saved, group name list chunk was placed wrong,
128 dimension region chunks also placed wrong
129 - added initialization of some fixed info strings in file and
130 instrument
131 - write support: files created by libgig will now have the RIFF
132 chunks in correct order

140 instruments
141 - write support: improved the default values for dimension region
142 parameters
143 - more write support fixes: crossfade parameters were not saved,
144 v3 dimension limits were not correctly initialized and saved
145 when dimensions were added or deleted, v3 wave pool offsets were
146 not saved correctly
147 - write support: 24 bit samples can now be written
148 - write support: version 3 is now the default for new files
149 - more write support fixes: the 3ewg chunk is now bigger for v3,
150 dimension regions without mapped samples are now allowed, 3gnl
151 list in v3 files now always has 128 entries, several parameters
152 where incorrectly saved due to an operator precedence mistake
153 - DeleteSample now removes all references to the deleted sample
154 - AddDimension now copies all parameters from existing dimension
155 regions and also makes sure that the samplechannel dimension is
156 placed first in the list of dimensions.
157 - added method GetParent() to class 'DimensionRegion', which returns its
158 parent Region
159 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
160 unused areas
161 - added various setter methods to DimensionRegion class which take care
162 of updating lookup tables / caches.

179 - custom velocity splits now works for gig v3 files too
180 - added support for custom splits points for other dimensions than
181 velocity (gig v3 feature)
182 - added "smart midi" and "round robin keyboard" dimensions
183 - added new method File::DeleteGroupOnly() which only deletes the given
184 group but moves all its members to another group, the other method,
185 that is File::DeleteGroup() now removes not just the group, but also
186 all the samples that belong to that group
187 - fixed crash which occured on interfering File::DeleteSample() and
188 File::GetNextSample() calls (due to iterator invalidation)
189 - fixed group names which were not saved
190 - fixed group destructor which did not remove the RIFF chunk associated
191 with the group
192 - added Instrument::MoveRegion method
193 - fixed constructor for Region, which did not initialize correctly
194 when used from Instrument::AddRegion
195 - when saving, override the gig::Regions sample reference simply by
196 the region's first dimension region's sample (avoids an exception
197 when trying to save a new instrument)
198 - fixed AddDimension() method which did not fill out all mandatory
199 dimension definition fields
200
201 * src/DLS.cpp, src/DLS.h:
202 - added Instrument::MoveRegion method

205
206 * src/RIFF.cpp, src/RIFF.h:

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

334 articulation informations are ignored at the moment
335 (patch by Andreas Persson)
336 - added some file format compatibility checks
337 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

387
388 * packaging changes:
389 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

391 - fixed man pages automake install rule (which didn't work on Mandrake,
392 SuSE and Fedora)
393 - fixed generation of Doxygen API documentation (now also included in
394 RPM and Debian packages)
395
396 * src/gig.cpp, src/gig.h:
397 - fixed / improved accuracy of all three velocity to volume
398 transformation functions a.k.a. 'nonlinear','linear','special'
399 (patch by Andreas Persson)
400 - denormals are filtered from the velocity to volume tables
401 - bugfix for dimension region switching (wrong handling of the release
402 trigger dimension, no bit range check for dimensions of split type

424 - added libgig.spec and libgig.pc package configurations for generating
425 Redhat packages
426 - header files included on installation.
427 - autotools-generated files removed from CVS repository.
428 - added support for generating Debian packages
429 - version of shared library can be set in configure.in
430
431 Version 0.7.0 (3 May 2004)
432
433 * general changes:
434 - various big endian specific corrections
435 (successfully tested now on PPC)
436 - minor adjustments to avoid compile errors on some systems
437 (using now pow() instead of powl() and --pedantic g++ compiler switch)
438 - libtoolized the library
439 - added man pages for the command line tools
440 (gigextract, gigdump, dlsdump, rifftree)
441
442 * src/gig.cpp, src/gig.h:
443 - fixed bug in decompression algorithm which caused it not to detect
444 the end of a stream
445 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
446 takes the MIDI key velocity value as an argument and returns the
447 appropriate volume factor (0.0 ... 1.0) for the sample to be played
448 back, the velocity curve transformation functions used for this are
449 only an approximation so far
450 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
451 'Sample::LoopSize' which reflected wrong values
452 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
453 measured in sample points instead of byte offset
454 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
455 'Sample::FineTune'
456 - added class attribute 'Sample::LoopSize'
457 - added method GetInstrument(uint index) to class 'File'
458 - added ReadAndLoop() method to class 'Sample' which is an extension to
459 the normal Read() method to honor the sample's looping information
460 while streaming from disk
461 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
462 'eg2_ctrl_t': replaced this huge enumeration by a structure which
463 reflects the MIDI controller number in case of an ordinary control
464 change controller (this saves a huge switch-case block in the
465 application of the library user)
466 - renamed following attributes in class 'DimensionRegion':
467 'AttenuationContol' -> 'AttenuationController',
468 'InvertAttenuationControl' -> 'InvertAttenuationController',
469 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
470 - minor fix in API documentation for method GetVelocityAttenuation() in
471 class 'DimensionRegion'
472
473 * src/RIFF.cpp, src/RIFF.h:
474 - added additional API documentation
475 - minor fix in Chunk::Read() method (only a minor efficiency issue)
476
477 * src/gigdump.cpp:
478 - added printout of samples' looping informations
479
480 Version 0.6.0 (3 Nov 2003)
481
482 * initial release
