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

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

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

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

188 dimension definition fields
189
190 * src/DLS.cpp, src/DLS.h:

324 (patch by Andreas Persson)
325 - added some file format compatibility checks
326 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

381 SuSE and Fedora)
382 - fixed generation of Doxygen API documentation (now also included in
383 RPM and Debian packages)
384
385 * src/gig.cpp, src/gig.h:
386 - fixed / improved accuracy of all three velocity to volume
387 transformation functions a.k.a. 'nonlinear','linear','special'
388 (patch by Andreas Persson)
389 - denormals are filtered from the velocity to volume tables
390 - bugfix for dimension region switching (wrong handling of the release

413 - added libgig.spec and libgig.pc package configurations for generating
414 Redhat packages
415 - header files included on installation.
416 - autotools-generated files removed from CVS repository.
417 - added support for generating Debian packages
418 - version of shared library can be set in configure.in
419
420 Version 0.7.0 (3 May 2004)
421
422 * general changes:
423 - various big endian specific corrections
424 (successfully tested now on PPC)
425 - minor adjustments to avoid compile errors on some systems
426 (using now pow() instead of powl() and --pedantic g++ compiler switch)
427 - libtoolized the library
428 - added man pages for the command line tools
429 (gigextract, gigdump, dlsdump, rifftree)
430
431 * src/gig.cpp, src/gig.h:
432 - fixed bug in decompression algorithm which caused it not to detect
433 the end of a stream
434 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
435 takes the MIDI key velocity value as an argument and returns the
436 appropriate volume factor (0.0 ... 1.0) for the sample to be played
437 back, the velocity curve transformation functions used for this are
438 only an approximation so far
439 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
440 'Sample::LoopSize' which reflected wrong values
441 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
442 measured in sample points instead of byte offset
443 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
444 'Sample::FineTune'
445 - added class attribute 'Sample::LoopSize'
446 - added method GetInstrument(uint index) to class 'File'
447 - added ReadAndLoop() method to class 'Sample' which is an extension to
448 the normal Read() method to honor the sample's looping information
449 while streaming from disk
450 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
451 'eg2_ctrl_t': replaced this huge enumeration by a structure which
452 reflects the MIDI controller number in case of an ordinary control
453 change controller (this saves a huge switch-case block in the
454 application of the library user)
455 - renamed following attributes in class 'DimensionRegion':
456 'AttenuationContol' -> 'AttenuationController',
457 'InvertAttenuationControl' -> 'InvertAttenuationController',
458 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
459 - minor fix in API documentation for method GetVelocityAttenuation() in
460 class 'DimensionRegion'
461
462 * src/RIFF.cpp, src/RIFF.h:
463 - added additional API documentation
464 - minor fix in Chunk::Read() method (only a minor efficiency issue)
465
466 * src/gigdump.cpp:
467 - added printout of samples' looping informations
468
469 Version 0.6.0 (3 Nov 2003)
470
471 * initial release
