* more write support fixes: crossfade parameters were not saved, v3
  dimension limits were not correctly initialized and saved when
  dimensions were added or deleted, v3 wave pool offsets were not
  saved correctly

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
47 * src/RIFF.cpp, src/RIFF.h:
48 - added File::SetByteOrder method
49
50 Version 3.1.1 (24 Mar 2007)
51
52 * packaging changes:
53 - ported to Windows using native Windows functions for file IO
54 (provided Dev-C++ + mingw project file)
55 - only export relevant files to Doxygen API documentation
56
57 * src/gig.cpp, src/gig.h:
58 - custom velocity splits now works for gig v3 files too
59 - added support for custom splits points for other dimensions than
60 velocity (gig v3 feature)
61 - added "smart midi" and "round robin keyboard" dimensions
62 - added new method File::DeleteGroupOnly() which only deletes the given
63 group but moves all its members to another group, the other method,
64 that is File::DeleteGroup() now removes not just the group, but also
65 all the samples that belong to that group
66 - fixed crash which occured on interfering File::DeleteSample() and
67 File::GetNextSample() calls (due to iterator invalidation)
68 - fixed group names which were not saved
69 - fixed group destructor which did not remove the RIFF chunk associated
70 with the group
71 - added Instrument::MoveRegion method
72 - fixed constructor for Region, which did not initialize correctly
73 when used from Instrument::AddRegion
74 - when saving, override the gig::Regions sample reference simply by
75 the region's first dimension region's sample (avoids an exception
76 when trying to save a new instrument)
77 - fixed AddDimension() method which did not fill out all mandatory
78 dimension definition fields
79
80 * src/DLS.cpp, src/DLS.h:
81 - added Instrument::MoveRegion method
82 - fixed software info field which was wrongly stored on instruments,
83 causing an exception when trying to save a new instrument
84
85 * src/RIFF.cpp, src/RIFF.h:
86 - fixed RIFF::Chunk destructor which did not unregister previously
87 resized chunks, leading to a "zero size chunk" exception when
88 File::Save() was called
89 - added List::MoveSubChunk method
90
91 Version 3.1.0 (24 Nov 2006)
92

102 instead of the wave chunk
103 - keyswitching dimension is changed from split type "normal" to

143 splits not equal to a power of two
144 - added write support (highly experimental)

214 (patch by Andreas Persson)
215 - added some file format compatibility checks
216 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

271 SuSE and Fedora)
272 - fixed generation of Doxygen API documentation (now also included in
273 RPM and Debian packages)
274
275 * src/gig.cpp, src/gig.h:
276 - fixed / improved accuracy of all three velocity to volume
277 transformation functions a.k.a. 'nonlinear','linear','special'
278 (patch by Andreas Persson)
279 - denormals are filtered from the velocity to volume tables
280 - bugfix for dimension region switching (wrong handling of the release

300 Version 0.7.1 (2 Jul 2004)
301
302 * packaging changes:
303 - added libgig.spec and libgig.pc package configurations for generating
304 Redhat packages
305 - header files included on installation.
306 - autotools-generated files removed from CVS repository.
307 - added support for generating Debian packages
308 - version of shared library can be set in configure.in
309
310 Version 0.7.0 (3 May 2004)
311
312 * general changes:
313 - various big endian specific corrections
314 (successfully tested now on PPC)
315 - minor adjustments to avoid compile errors on some systems
316 (using now pow() instead of powl() and --pedantic g++ compiler switch)
317 - libtoolized the library
318 - added man pages for the command line tools
319 (gigextract, gigdump, dlsdump, rifftree)
320
321 * src/gig.cpp, src/gig.h:
322 - fixed bug in decompression algorithm which caused it not to detect
323 the end of a stream
324 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
325 takes the MIDI key velocity value as an argument and returns the
326 appropriate volume factor (0.0 ... 1.0) for the sample to be played
327 back, the velocity curve transformation functions used for this are
328 only an approximation so far
329 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
330 'Sample::LoopSize' which reflected wrong values
331 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
332 measured in sample points instead of byte offset
333 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
334 'Sample::FineTune'
335 - added class attribute 'Sample::LoopSize'
336 - added method GetInstrument(uint index) to class 'File'
337 - added ReadAndLoop() method to class 'Sample' which is an extension to
338 the normal Read() method to honor the sample's looping information
339 while streaming from disk
340 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
341 'eg2_ctrl_t': replaced this huge enumeration by a structure which
342 reflects the MIDI controller number in case of an ordinary control
343 change controller (this saves a huge switch-case block in the
344 application of the library user)
345 - renamed following attributes in class 'DimensionRegion':
346 'AttenuationContol' -> 'AttenuationController',
347 'InvertAttenuationControl' -> 'InvertAttenuationController',
348 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
349 - minor fix in API documentation for method GetVelocityAttenuation() in
350 class 'DimensionRegion'
351
352 * src/RIFF.cpp, src/RIFF.h:
353 - added additional API documentation
354 - minor fix in Chunk::Read() method (only a minor efficiency issue)
355
356 * src/gigdump.cpp:
357 - added printout of samples' looping informations
358
359 Version 0.6.0 (3 Nov 2003)
360
361 * initial release
