31 - fixes for building with Visual C++
32 - minor fix in configure for building DLL on Windows
33

35 - added partial support for MIDI rules, only the Controller
36 Triggered rule is supported so far
37 - bugfix: removed another iterator invalidation in DeleteSample
38 - bugfix in Sample::LoadSampleData*(): reset sample read position to

98 - added missing parameter initalizations in sample, region and
99 instrument constructors
100 - clear unused fields when saving samples and regions
101 - fixed write support bugs: v3 dimension limits and chunksize
102 weren't saved, leverage controller of type controlchange
103 couldn't be saved, group name list chunk was placed wrong,
104 dimension region chunks also placed wrong
105 - added initialization of some fixed info strings in file and
106 instrument
107 - write support: files created by libgig will now have the RIFF
108 chunks in correct order

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

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

310 articulation informations are ignored at the moment
311 (patch by Andreas Persson)
312 - added some file format compatibility checks
313 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

368 SuSE and Fedora)
369 - fixed generation of Doxygen API documentation (now also included in
370 RPM and Debian packages)
371
372 * src/gig.cpp, src/gig.h:
373 - fixed / improved accuracy of all three velocity to volume
374 transformation functions a.k.a. 'nonlinear','linear','special'
375 (patch by Andreas Persson)
376 - denormals are filtered from the velocity to volume tables
377 - bugfix for dimension region switching (wrong handling of the release
378 trigger dimension, no bit range check for dimensions of split type

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