24 - fixes for building with Visual C++
25 - minor fix in configure for building DLL on Windows
26
27 * src/gig.cpp, src/gig.h:
28 - added partial support for MIDI rules, only the Controller
29 Triggered rule is supported so far
30 - bugfix: removed another iterator invalidation in DeleteSample
31 - bugfix in Sample::LoadSampleData*(): reset sample read position to
32 sample start before trying to (re)load sample data from file (#82)
33 - bugfix: EG3 depth parameter was not saved correctly
34 - fixed crash which occured when streaming a gig sample with
35 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)

38 - bugfix: saving to the same file after the file size had been
39 increased made the file corrupt (#82)
40 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
41 is not written physically yet (#82)
42 - bugfix: saving to the same file after the file size had been

47 of derived class RIFF::File, which is bad, and caused crashes
48 when using Visual C++
49 - bugfix: files that contain zero length RIFF lists were not read
50 correctly (fixes #127) (bug was introduced 2009-03-13)
51

60 applications to retrieve very superficial informations like amount of
61 instruments and their names in a very fast way
62
63 Version 3.2.0 (14 Oct 2007)
64
65 * packaging changes:
66 - added Mac OSX XCode project files (patch by Toshi Nagata)

91 - added missing parameter initalizations in sample, region and
92 instrument constructors
93 - clear unused fields when saving samples and regions
94 - fixed write support bugs: v3 dimension limits and chunksize
95 weren't saved, leverage controller of type controlchange
96 couldn't be saved, group name list chunk was placed wrong,
97 dimension region chunks also placed wrong
98 - added initialization of some fixed info strings in file and
99 instrument

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

148 - custom velocity splits now works for gig v3 files too
149 - added support for custom splits points for other dimensions than
150 velocity (gig v3 feature)
151 - added "smart midi" and "round robin keyboard" dimensions
152 - added new method File::DeleteGroupOnly() which only deletes the given
153 group but moves all its members to another group, the other method,
154 that is File::DeleteGroup() now removes not just the group, but also
155 all the samples that belong to that group
156 - fixed crash which occured on interfering File::DeleteSample() and
157 File::GetNextSample() calls (due to iterator invalidation)
158 - fixed group names which were not saved

160 with the group
161 - added Instrument::MoveRegion method
162 - fixed constructor for Region, which did not initialize correctly
163 when used from Instrument::AddRegion
164 - when saving, override the gig::Regions sample reference simply by
165 the region's first dimension region's sample (avoids an exception
166 when trying to save a new instrument)

168 dimension definition fields
169
170 * src/DLS.cpp, src/DLS.h:

303 articulation informations are ignored at the moment
304 (patch by Andreas Persson)
305 - added some file format compatibility checks
306 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

361 SuSE and Fedora)
362 - fixed generation of Doxygen API documentation (now also included in
363 RPM and Debian packages)
364
365 * src/gig.cpp, src/gig.h:
366 - fixed / improved accuracy of all three velocity to volume
367 transformation functions a.k.a. 'nonlinear','linear','special'
368 (patch by Andreas Persson)
369 - denormals are filtered from the velocity to volume tables

399
400 Version 0.7.0 (3 May 2004)
401
402 * general changes:
403 - various big endian specific corrections
404 (successfully tested now on PPC)
405 - minor adjustments to avoid compile errors on some systems
406 (using now pow() instead of powl() and --pedantic g++ compiler switch)
407 - libtoolized the library
408 - added man pages for the command line tools
409 (gigextract, gigdump, dlsdump, rifftree)
410
411 * src/gig.cpp, src/gig.h:
412 - fixed bug in decompression algorithm which caused it not to detect
413 the end of a stream
414 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
415 takes the MIDI key velocity value as an argument and returns the
416 appropriate volume factor (0.0 ... 1.0) for the sample to be played
417 back, the velocity curve transformation functions used for this are
418 only an approximation so far
419 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
420 'Sample::LoopSize' which reflected wrong values
421 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
422 measured in sample points instead of byte offset
423 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
424 'Sample::FineTune'
425 - added class attribute 'Sample::LoopSize'
426 - added method GetInstrument(uint index) to class 'File'
427 - added ReadAndLoop() method to class 'Sample' which is an extension to
428 the normal Read() method to honor the sample's looping information
429 while streaming from disk
430 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
431 'eg2_ctrl_t': replaced this huge enumeration by a structure which
432 reflects the MIDI controller number in case of an ordinary control
433 change controller (this saves a huge switch-case block in the
434 application of the library user)
435 - renamed following attributes in class 'DimensionRegion':
436 'AttenuationContol' -> 'AttenuationController',
437 'InvertAttenuationControl' -> 'InvertAttenuationController',
438 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
439 - minor fix in API documentation for method GetVelocityAttenuation() in
440 class 'DimensionRegion'
441
442 * src/RIFF.cpp, src/RIFF.h:
443 - added additional API documentation
444 - minor fix in Chunk::Read() method (only a minor efficiency issue)
445
446 * src/gigdump.cpp:
447 - added printout of samples' looping informations
448
449 Version 0.6.0 (3 Nov 2003)
450
451 * initial release
