1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - added Mac OSX XCode project files (patch by Toshi Nagata)
5 - Dev-C++ (win32) project file is automatically updated with
6 the version info from configure.in
7
8 * src/DLS.cpp, src/DLS.h:
9 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
10 - fixed write support for big-endian systems
11 - improved handling of fixed length info strings - separate default
12 lengths can be specified for each INFO chunk
13 - added Resource::GenerateDLSID function
14
15 * src/gig.cpp, src/gig.h:
16 - fixed segmentation fault in the gig::File destructor sequence which
17 happened when gig::Group informations were accessed before
18 - fixed write support for big-endian systems
19 - defined lengths of a fixed set of info strings. These strings
20 are saved when the file is written, even if they are empty.
21 - added missing parameter initalizations in sample, region and
22 instrument constructors
23 - clear unused fields when saving samples and regions
24 - fixed write support bugs: v3 dimension limits and chunksize
25 weren't saved, leverage controller of type controlchange
26 couldn't be saved, group name list chunk was placed wrong,
27 dimension region chunks also placed wrong
28 - added initialization of some fixed info strings in file and
29 instrument
30 - write support: files created by libgig will now have the RIFF
31 chunks in correct order
32 - write support: two previously unknown fields in dimension
33 definition are now saved
34 - added constants for gig file versions
35 - write support: the 3crc and einf chunks are now created or
36 updated when a file is saved (3crc contains sample checksums,
37 einf contains file statistics)
38 - write support: DLSID is now generated on the file and the
39 instruments
40 - write support: improved the default values for dimension region
41 parameters
42 - more write support fixes: crossfade parameters were not saved,
43 v3 dimension limits were not correctly initialized and saved
44 when dimensions were added or deleted, v3 wave pool offsets were
45 not saved correctly
46 - write support: 24 bit samples can now be written
47 - write support: version 3 is now the default for new files
48 - more write support fixes: the 3ewg chunk is now bigger for v3
49
50 * src/RIFF.cpp, src/RIFF.h:
51 - added File::SetByteOrder method
52
53 * src/gigdump.cpp:
54 - added some missing dimension strings
55
56 Version 3.1.1 (24 Mar 2007)
57
58 * packaging changes:
59 - ported to Windows using native Windows functions for file IO
60 (provided Dev-C++ + mingw project file)
61 - only export relevant files to Doxygen API documentation
62
63 * src/gig.cpp, src/gig.h:
64 - custom velocity splits now works for gig v3 files too
65 - added support for custom splits points for other dimensions than
66 velocity (gig v3 feature)
67 - added "smart midi" and "round robin keyboard" dimensions
68 - added new method File::DeleteGroupOnly() which only deletes the given
69 group but moves all its members to another group, the other method,
70 that is File::DeleteGroup() now removes not just the group, but also
71 all the samples that belong to that group
72 - fixed crash which occured on interfering File::DeleteSample() and
73 File::GetNextSample() calls (due to iterator invalidation)
74 - fixed group names which were not saved
75 - fixed group destructor which did not remove the RIFF chunk associated
76 with the group
77 - added Instrument::MoveRegion method
78 - fixed constructor for Region, which did not initialize correctly
79 when used from Instrument::AddRegion
80 - when saving, override the gig::Regions sample reference simply by
81 the region's first dimension region's sample (avoids an exception
82 when trying to save a new instrument)
83 - fixed AddDimension() method which did not fill out all mandatory
84 dimension definition fields
85
86 * src/DLS.cpp, src/DLS.h:
87 - added Instrument::MoveRegion method
88 - fixed software info field which was wrongly stored on instruments,
89 causing an exception when trying to save a new instrument
90
91 * src/RIFF.cpp, src/RIFF.h:
92 - fixed RIFF::Chunk destructor which did not unregister previously
93 resized chunks, leading to a "zero size chunk" exception when
94 File::Save() was called
95 - added List::MoveSubChunk method
96
97 Version 3.1.0 (24 Nov 2006)
98

158 - added write support
159 - Chunk::LoadChunkData() can now be called again to resize the buffer
160 after a Chunk::Resize() and before the File::Save() call to allow

219 articulation informations are ignored at the moment
220 (patch by Andreas Persson)
221 - added some file format compatibility checks
222 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

272
273 * packaging changes:
274 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
275 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
276 - fixed man pages automake install rule (which didn't work on Mandrake,
277 SuSE and Fedora)
278 - fixed generation of Doxygen API documentation (now also included in
279 RPM and Debian packages)
280
281 * src/gig.cpp, src/gig.h:
282 - fixed / improved accuracy of all three velocity to volume
283 transformation functions a.k.a. 'nonlinear','linear','special'
284 (patch by Andreas Persson)
285 - denormals are filtered from the velocity to volume tables
286 - bugfix for dimension region switching (wrong handling of the release
287 trigger dimension, no bit range check for dimensions of split type

307
308 * packaging changes:
309 - added libgig.spec and libgig.pc package configurations for generating
310 Redhat packages
311 - header files included on installation.
312 - autotools-generated files removed from CVS repository.
313 - added support for generating Debian packages
314 - version of shared library can be set in configure.in
315
316 Version 0.7.0 (3 May 2004)
317
318 * general changes:
319 - various big endian specific corrections
320 (successfully tested now on PPC)
321 - minor adjustments to avoid compile errors on some systems
322 (using now pow() instead of powl() and --pedantic g++ compiler switch)
323 - libtoolized the library
324 - added man pages for the command line tools
325 (gigextract, gigdump, dlsdump, rifftree)
326
327 * src/gig.cpp, src/gig.h:
328 - fixed bug in decompression algorithm which caused it not to detect
329 the end of a stream
330 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
331 takes the MIDI key velocity value as an argument and returns the
332 appropriate volume factor (0.0 ... 1.0) for the sample to be played
333 back, the velocity curve transformation functions used for this are
334 only an approximation so far
335 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
336 'Sample::LoopSize' which reflected wrong values
337 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
338 measured in sample points instead of byte offset
339 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
340 'Sample::FineTune'
341 - added class attribute 'Sample::LoopSize'
342 - added method GetInstrument(uint index) to class 'File'
343 - added ReadAndLoop() method to class 'Sample' which is an extension to
344 the normal Read() method to honor the sample's looping information
345 while streaming from disk
346 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
347 'eg2_ctrl_t': replaced this huge enumeration by a structure which
348 reflects the MIDI controller number in case of an ordinary control
349 change controller (this saves a huge switch-case block in the
350 application of the library user)
351 - renamed following attributes in class 'DimensionRegion':
352 'AttenuationContol' -> 'AttenuationController',
353 'InvertAttenuationControl' -> 'InvertAttenuationController',
354 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
355 - minor fix in API documentation for method GetVelocityAttenuation() in
356 class 'DimensionRegion'
357
358 * src/RIFF.cpp, src/RIFF.h:
359 - added additional API documentation
360 - minor fix in Chunk::Read() method (only a minor efficiency issue)
361
362 * src/gigdump.cpp:
363 - added printout of samples' looping informations
364
365 Version 0.6.0 (3 Nov 2003)
366
367 * initial release
