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

73
74 * src/gig.cpp, src/gig.h:
75 - added support for more than one set of custom velocity splits
76 inside a region (for example different velocity split levels for
77 pedal up and pedal down)
78 - sample loop parameters are now taken from the DimensionRegion
79 instead of the wave chunk
80 - keyswitching dimension is changed from split type "normal" to
81 "bit"
82 - real support for 24 bit samples - samples are not truncated to
83 16 bits anymore

87 - support for sample groups added
88
89 * src/DLS.cpp, src/DLS.h:

104 of Gigasampler write support)
105
106 Version 3.0.0 (28 Apr 2006)
107
108 * general changes:
109 - added write support (that is for creating and modifying RIFF, DLS and

112 files are now loaded even if mandatory RIFF chunks are missing
113 - fixed some memory management errors, one of them was causing a
114 crash when a multi-file gig was deallocated
115
116 * src/gig.cpp, src/gig.h:
117 - fixed the GetVelocityCutoff function, it wasn't always using the
118 VCFVelocityScale parameter when no cutoff controller was defined

120 splits not equal to a power of two
121 - added write support (highly experimental)
122
123 * src/DLS.cpp, src/DLS.h:
124 - fixed loading of Articulation Connections (<artl> list chunks were

126 - added write support (highly experimental)
127
128 * src/RIFF.cpp, src/RIFF.h:
129 - added write support
130 - Chunk::LoadChunkData() can now be called again to resize the buffer
131 after a Chunk::Resize() and before the File::Save() call to allow
132 placing the new data in the chunk's write buffer and perform the
133 resize and write operations in one rush
134
135 * src/gigdump.cpp:
136 - fixed to show the correct amount of dimension regions instead of 32
137 (patch by James Wylder)

150 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
151 the extension files are read automatically when the samples are
152 loaded
153 - fixed the 24 bit decompression, the result should now be exact
154 instead of an approximation

190 articulation informations are ignored at the moment
191 (patch by Andreas Persson)
192 - added some file format compatibility checks
193 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

243
244 * packaging changes:
245 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
246 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
247 - fixed man pages automake install rule (which didn't work on Mandrake,
248 SuSE and Fedora)
249 - fixed generation of Doxygen API documentation (now also included in
250 RPM and Debian packages)
251
252 * src/gig.cpp, src/gig.h:
253 - fixed / improved accuracy of all three velocity to volume
254 transformation functions a.k.a. 'nonlinear','linear','special'
255 (patch by Andreas Persson)
256 - denormals are filtered from the velocity to volume tables
257 - bugfix for dimension region switching (wrong handling of the release
258 trigger dimension, no bit range check for dimensions of split type

277 Version 0.7.1 (2 Jul 2004)
278
279 * packaging changes:
280 - added libgig.spec and libgig.pc package configurations for generating
281 Redhat packages
282 - header files included on installation.
283 - autotools-generated files removed from CVS repository.
284 - added support for generating Debian packages
285 - version of shared library can be set in configure.in
286
287 Version 0.7.0 (3 May 2004)
288
289 * general changes:
290 - various big endian specific corrections
291 (successfully tested now on PPC)
292 - minor adjustments to avoid compile errors on some systems
293 (using now pow() instead of powl() and --pedantic g++ compiler switch)
294 - libtoolized the library
295 - added man pages for the command line tools
296 (gigextract, gigdump, dlsdump, rifftree)
297
298 * src/gig.cpp, src/gig.h:
299 - fixed bug in decompression algorithm which caused it not to detect
300 the end of a stream
301 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
302 takes the MIDI key velocity value as an argument and returns the
303 appropriate volume factor (0.0 ... 1.0) for the sample to be played
304 back, the velocity curve transformation functions used for this are
305 only an approximation so far
306 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
307 'Sample::LoopSize' which reflected wrong values
308 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
309 measured in sample points instead of byte offset
310 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
311 'Sample::FineTune'
312 - added class attribute 'Sample::LoopSize'
313 - added method GetInstrument(uint index) to class 'File'
314 - added ReadAndLoop() method to class 'Sample' which is an extension to
315 the normal Read() method to honor the sample's looping information
316 while streaming from disk
317 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
318 'eg2_ctrl_t': replaced this huge enumeration by a structure which
319 reflects the MIDI controller number in case of an ordinary control
320 change controller (this saves a huge switch-case block in the
321 application of the library user)
322 - renamed following attributes in class 'DimensionRegion':
323 'AttenuationContol' -> 'AttenuationController',
324 'InvertAttenuationControl' -> 'InvertAttenuationController',
325 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
326 - minor fix in API documentation for method GetVelocityAttenuation() in
327 class 'DimensionRegion'
328
329 * src/RIFF.cpp, src/RIFF.h:
330 - added additional API documentation
331 - minor fix in Chunk::Read() method (only a minor efficiency issue)
332
333 * src/gigdump.cpp:
334 - added printout of samples' looping informations
335
336 Version 0.6.0 (3 Nov 2003)
337
338 * initial release
