34 - fixes for building with Visual C++
35 - minor fix in configure for building DLL on Windows

57 of derived class RIFF::File, which is bad, and caused crashes
58 when using Visual C++
59 - bugfix: files that contain zero length RIFF lists were not read
60 correctly (fixes #127) (bug was introduced 2009-03-13)
61

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

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

158 - custom velocity splits now works for gig v3 files too
159 - added support for custom splits points for other dimensions than
160 velocity (gig v3 feature)
161 - added "smart midi" and "round robin keyboard" dimensions
162 - added new method File::DeleteGroupOnly() which only deletes the given
163 group but moves all its members to another group, the other method,
164 that is File::DeleteGroup() now removes not just the group, but also
165 all the samples that belong to that group
166 - fixed crash which occured on interfering File::DeleteSample() and
167 File::GetNextSample() calls (due to iterator invalidation)
168 - fixed group names which were not saved
169 - fixed group destructor which did not remove the RIFF chunk associated
170 with the group
171 - added Instrument::MoveRegion method
172 - fixed constructor for Region, which did not initialize correctly
173 when used from Instrument::AddRegion
174 - when saving, override the gig::Regions sample reference simply by
175 the region's first dimension region's sample (avoids an exception
176 when trying to save a new instrument)
177 - fixed AddDimension() method which did not fill out all mandatory
178 dimension definition fields
179
180 * src/DLS.cpp, src/DLS.h:
181 - added Instrument::MoveRegion method

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

373 RPM and Debian packages)
374
375 * src/gig.cpp, src/gig.h:
376 - fixed / improved accuracy of all three velocity to volume
377 transformation functions a.k.a. 'nonlinear','linear','special'
378 (patch by Andreas Persson)
379 - denormals are filtered from the velocity to volume tables
380 - bugfix for dimension region switching (wrong handling of the release

409
410 Version 0.7.0 (3 May 2004)
411
412 * general changes:
413 - various big endian specific corrections
414 (successfully tested now on PPC)
415 - minor adjustments to avoid compile errors on some systems
416 (using now pow() instead of powl() and --pedantic g++ compiler switch)
417 - libtoolized the library
418 - added man pages for the command line tools
419 (gigextract, gigdump, dlsdump, rifftree)
420
421 * src/gig.cpp, src/gig.h:
422 - fixed bug in decompression algorithm which caused it not to detect
423 the end of a stream
424 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
425 takes the MIDI key velocity value as an argument and returns the
426 appropriate volume factor (0.0 ... 1.0) for the sample to be played
427 back, the velocity curve transformation functions used for this are
428 only an approximation so far
429 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
430 'Sample::LoopSize' which reflected wrong values
431 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
432 measured in sample points instead of byte offset
433 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
434 'Sample::FineTune'
435 - added class attribute 'Sample::LoopSize'
436 - added method GetInstrument(uint index) to class 'File'
437 - added ReadAndLoop() method to class 'Sample' which is an extension to
438 the normal Read() method to honor the sample's looping information
439 while streaming from disk
440 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
441 'eg2_ctrl_t': replaced this huge enumeration by a structure which
442 reflects the MIDI controller number in case of an ordinary control
443 change controller (this saves a huge switch-case block in the
444 application of the library user)
445 - renamed following attributes in class 'DimensionRegion':
446 'AttenuationContol' -> 'AttenuationController',
447 'InvertAttenuationControl' -> 'InvertAttenuationController',
448 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
449 - minor fix in API documentation for method GetVelocityAttenuation() in
450 class 'DimensionRegion'
451
452 * src/RIFF.cpp, src/RIFF.h:
453 - added additional API documentation
454 - minor fix in Chunk::Read() method (only a minor efficiency issue)
455
456 * src/gigdump.cpp:
457 - added printout of samples' looping informations
458
459 Version 0.6.0 (3 Nov 2003)
460
461 * initial release
