81
82 * packaging changes:
83 - added Mac OSX XCode project files (patch by Toshi Nagata)

108 - added missing parameter initalizations in sample, region and
109 instrument constructors
110 - clear unused fields when saving samples and regions
111 - fixed write support bugs: v3 dimension limits and chunksize
112 weren't saved, leverage controller of type controlchange
113 couldn't be saved, group name list chunk was placed wrong,
114 dimension region chunks also placed wrong
115 - added initialization of some fixed info strings in file and
116 instrument

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

166 - added support for custom splits points for other dimensions than
167 velocity (gig v3 feature)
168 - added "smart midi" and "round robin keyboard" dimensions
169 - added new method File::DeleteGroupOnly() which only deletes the given
170 group but moves all its members to another group, the other method,
171 that is File::DeleteGroup() now removes not just the group, but also
172 all the samples that belong to that group
173 - fixed crash which occured on interfering File::DeleteSample() and
174 File::GetNextSample() calls (due to iterator invalidation)
175 - fixed group names which were not saved

177 with the group
178 - added Instrument::MoveRegion method
179 - fixed constructor for Region, which did not initialize correctly
180 when used from Instrument::AddRegion
181 - when saving, override the gig::Regions sample reference simply by
182 the region's first dimension region's sample (avoids an exception
183 when trying to save a new instrument)

185 dimension definition fields
186
187 * src/DLS.cpp, src/DLS.h:

320 articulation informations are ignored at the moment
321 (patch by Andreas Persson)
322 - added some file format compatibility checks
323 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

378 SuSE and Fedora)
379 - fixed generation of Doxygen API documentation (now also included in
380 RPM and Debian packages)
381
382 * src/gig.cpp, src/gig.h:
383 - fixed / improved accuracy of all three velocity to volume
384 transformation functions a.k.a. 'nonlinear','linear','special'
385 (patch by Andreas Persson)
386 - denormals are filtered from the velocity to volume tables
387 - bugfix for dimension region switching (wrong handling of the release
388 trigger dimension, no bit range check for dimensions of split type

410 - added libgig.spec and libgig.pc package configurations for generating
411 Redhat packages
412 - header files included on installation.
413 - autotools-generated files removed from CVS repository.
414 - added support for generating Debian packages
415 - version of shared library can be set in configure.in
416
417 Version 0.7.0 (3 May 2004)
418
419 * general changes:
420 - various big endian specific corrections
421 (successfully tested now on PPC)
422 - minor adjustments to avoid compile errors on some systems
423 (using now pow() instead of powl() and --pedantic g++ compiler switch)
424 - libtoolized the library
425 - added man pages for the command line tools
426 (gigextract, gigdump, dlsdump, rifftree)
427
428 * src/gig.cpp, src/gig.h:
429 - fixed bug in decompression algorithm which caused it not to detect
430 the end of a stream
431 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
432 takes the MIDI key velocity value as an argument and returns the
433 appropriate volume factor (0.0 ... 1.0) for the sample to be played
434 back, the velocity curve transformation functions used for this are
435 only an approximation so far
436 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
437 'Sample::LoopSize' which reflected wrong values
438 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
439 measured in sample points instead of byte offset
440 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
441 'Sample::FineTune'
442 - added class attribute 'Sample::LoopSize'
443 - added method GetInstrument(uint index) to class 'File'
444 - added ReadAndLoop() method to class 'Sample' which is an extension to
445 the normal Read() method to honor the sample's looping information
446 while streaming from disk
447 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
448 'eg2_ctrl_t': replaced this huge enumeration by a structure which
449 reflects the MIDI controller number in case of an ordinary control
450 change controller (this saves a huge switch-case block in the
451 application of the library user)
452 - renamed following attributes in class 'DimensionRegion':
453 'AttenuationContol' -> 'AttenuationController',
454 'InvertAttenuationControl' -> 'InvertAttenuationController',
455 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
456 - minor fix in API documentation for method GetVelocityAttenuation() in
457 class 'DimensionRegion'
458
459 * src/RIFF.cpp, src/RIFF.h:
460 - added additional API documentation
461 - minor fix in Chunk::Read() method (only a minor efficiency issue)
462
463 * src/gigdump.cpp:
464 - added printout of samples' looping informations
465
466 Version 0.6.0 (3 Nov 2003)
467
468 * initial release
