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

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

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

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

198 dimension definition fields
199
200 * src/DLS.cpp, src/DLS.h:

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

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

386
387 * packaging changes:
388 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

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

405 - added class attribute 'Layers' to class 'gig::Region'
406 - symbol prototyping of gig::Region (fixes build failure with qsampler)
407

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