* write support: files created by libgig will now have the RIFF chunks
  in correct order

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
14 * src/gig.cpp, src/gig.h:
15 - fixed segmentation fault in the gig::File destructor sequence which
16 happened when gig::Group informations were accessed before
17 - fixed write support for big-endian systems
18 - defined lengths of a fixed set of info strings. These strings
19 are saved when the file is written, even if they are empty.
20 - added missing parameter initalizations in sample, region and
21 instrument constructors
22 - clear unused fields when saving samples and regions
23 - fixed write support bugs: v3 dimension limits and chunksize
24 weren't saved, leverage controller of type controlchange
25 couldn't be saved, group name list chunk was placed wrong
26 - added initialization of some fixed info strings in file and
27 instrument
28 - write support: files created by libgig will now have the RIFF
29 chunks in correct order
30
31 * src/RIFF.cpp, src/RIFF.h:
32 - added File::SetByteOrder method
33
34 Version 3.1.1 (24 Mar 2007)
35
36 * packaging changes:
37 - ported to Windows using native Windows functions for file IO
38 (provided Dev-C++ + mingw project file)
39 - only export relevant files to Doxygen API documentation
40
41 * src/gig.cpp, src/gig.h:
42 - custom velocity splits now works for gig v3 files too
43 - added support for custom splits points for other dimensions than
44 velocity (gig v3 feature)
45 - added "smart midi" and "round robin keyboard" dimensions
46 - added new method File::DeleteGroupOnly() which only deletes the given
47 group but moves all its members to another group, the other method,
48 that is File::DeleteGroup() now removes not just the group, but also
49 all the samples that belong to that group
50 - fixed crash which occured on interfering File::DeleteSample() and
51 File::GetNextSample() calls (due to iterator invalidation)
52 - fixed group names which were not saved
53 - fixed group destructor which did not remove the RIFF chunk associated
54 with the group
55 - added Instrument::MoveRegion method
56 - fixed constructor for Region, which did not initialize correctly
57 when used from Instrument::AddRegion
58 - when saving, override the gig::Regions sample reference simply by
59 the region's first dimension region's sample (avoids an exception
60 when trying to save a new instrument)
61 - fixed AddDimension() method which did not fill out all mandatory
62 dimension definition fields
63
64 * src/DLS.cpp, src/DLS.h:
65 - added Instrument::MoveRegion method
66 - fixed software info field which was wrongly stored on instruments,
67 causing an exception when trying to save a new instrument
68
69 * src/RIFF.cpp, src/RIFF.h:
70 - fixed RIFF::Chunk destructor which did not unregister previously
71 resized chunks, leading to a "zero size chunk" exception when
72 File::Save() was called
73 - added List::MoveSubChunk method
74
75 Version 3.1.0 (24 Nov 2006)
76
77 * packaging changes:
78 - changed deprecated copyright attribute to license;
79 added ldconfig to post-(un)install steps on libgig.spec (RPM)
80
81 * src/gig.cpp, src/gig.h:
82 - added support for more than one set of custom velocity splits
83 inside a region (for example different velocity split levels for
84 pedal up and pedal down)
85 - sample loop parameters are now taken from the DimensionRegion
86 instead of the wave chunk
87 - keyswitching dimension is changed from split type "normal" to
88 "bit"
89 - real support for 24 bit samples - samples are not truncated to
90 16 bits anymore

94 - support for sample groups added
95
96 * src/DLS.cpp, src/DLS.h:

112
113 Version 3.0.0 (28 Apr 2006)
114

119 files are now loaded even if mandatory RIFF chunks are missing
120 - fixed some memory management errors, one of them was causing a
121 crash when a multi-file gig was deallocated
122
123 * src/gig.cpp, src/gig.h:
124 - fixed the GetVelocityCutoff function, it wasn't always using the

127 splits not equal to a power of two
128 - added write support (highly experimental)
129
130 * src/DLS.cpp, src/DLS.h:

138 after a Chunk::Resize() and before the File::Save() call to allow
139 placing the new data in the chunk's write buffer and perform the
140 resize and write operations in one rush
141
142 * src/gigdump.cpp:
143 - fixed to show the correct amount of dimension regions instead of 32
144 (patch by James Wylder)

197 articulation informations are ignored at the moment
198 (patch by Andreas Persson)
199 - added some file format compatibility checks
200 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

250
251 * packaging changes:
252 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

255 SuSE and Fedora)
256 - fixed generation of Doxygen API documentation (now also included in
257 RPM and Debian packages)
258
259 * src/gig.cpp, src/gig.h:
260 - fixed / improved accuracy of all three velocity to volume
261 transformation functions a.k.a. 'nonlinear','linear','special'
262 (patch by Andreas Persson)
263 - denormals are filtered from the velocity to volume tables
264 - bugfix for dimension region switching (wrong handling of the release
265 trigger dimension, no bit range check for dimensions of split type

285
286 * packaging changes:
287 - added libgig.spec and libgig.pc package configurations for generating
288 Redhat packages
289 - header files included on installation.
290 - autotools-generated files removed from CVS repository.
291 - added support for generating Debian packages
292 - version of shared library can be set in configure.in
293
294 Version 0.7.0 (3 May 2004)
295
296 * general changes:
297 - various big endian specific corrections
298 (successfully tested now on PPC)
299 - minor adjustments to avoid compile errors on some systems
300 (using now pow() instead of powl() and --pedantic g++ compiler switch)
301 - libtoolized the library
302 - added man pages for the command line tools
303 (gigextract, gigdump, dlsdump, rifftree)
304
305 * src/gig.cpp, src/gig.h:
306 - fixed bug in decompression algorithm which caused it not to detect
307 the end of a stream
308 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
309 takes the MIDI key velocity value as an argument and returns the
310 appropriate volume factor (0.0 ... 1.0) for the sample to be played
311 back, the velocity curve transformation functions used for this are
312 only an approximation so far
313 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
314 'Sample::LoopSize' which reflected wrong values
315 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
316 measured in sample points instead of byte offset
317 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
318 'Sample::FineTune'
319 - added class attribute 'Sample::LoopSize'
320 - added method GetInstrument(uint index) to class 'File'
321 - added ReadAndLoop() method to class 'Sample' which is an extension to
322 the normal Read() method to honor the sample's looping information
323 while streaming from disk
324 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
325 'eg2_ctrl_t': replaced this huge enumeration by a structure which
326 reflects the MIDI controller number in case of an ordinary control
327 change controller (this saves a huge switch-case block in the
328 application of the library user)
329 - renamed following attributes in class 'DimensionRegion':
330 'AttenuationContol' -> 'AttenuationController',
331 'InvertAttenuationControl' -> 'InvertAttenuationController',
332 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
333 - minor fix in API documentation for method GetVelocityAttenuation() in
334 class 'DimensionRegion'
335
336 * src/RIFF.cpp, src/RIFF.h:
337 - added additional API documentation
338 - minor fix in Chunk::Read() method (only a minor efficiency issue)
339
340 * src/gigdump.cpp:
341 - added printout of samples' looping informations
342
343 Version 0.6.0 (3 Nov 2003)
344
345 * initial release
