* fixed write support for big-endian systems

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
10 * src/gig.cpp, src/gig.h:
11 - fixed segmentation fault in the gig::File destructor sequence which
12 happened when gig::Group informations were accessed before
13 - fixed write support for big-endian systems
14
15 Version 3.1.1 (24 Mar 2007)
16
17 * packaging changes:
18 - ported to Windows using native Windows functions for file IO
19 (provided Dev-C++ + mingw project file)
20 - only export relevant files to Doxygen API documentation
21
22 * src/gig.cpp, src/gig.h:
23 - custom velocity splits now works for gig v3 files too
24 - added support for custom splits points for other dimensions than
25 velocity (gig v3 feature)
26 - added "smart midi" and "round robin keyboard" dimensions
27 - added new method File::DeleteGroupOnly() which only deletes the given
28 group but moves all its members to another group, the other method,
29 that is File::DeleteGroup() now removes not just the group, but also
30 all the samples that belong to that group
31 - fixed crash which occured on interfering File::DeleteSample() and
32 File::GetNextSample() calls (due to iterator invalidation)
33 - fixed group names which were not saved
34 - fixed group destructor which did not remove the RIFF chunk associated
35 with the group
36 - added Instrument::MoveRegion method
37 - fixed constructor for Region, which did not initialize correctly
38 when used from Instrument::AddRegion
39 - when saving, override the gig::Regions sample reference simply by
40 the region's first dimension region's sample (avoids an exception
41 when trying to save a new instrument)
42 - fixed AddDimension() method which did not fill out all mandatory
43 dimension definition fields
44
45 * src/DLS.cpp, src/DLS.h:
46 - added Instrument::MoveRegion method
47 - fixed software info field which was wrongly stored on instruments,
48 causing an exception when trying to save a new instrument
49
50 * src/RIFF.cpp, src/RIFF.h:
51 - fixed RIFF::Chunk destructor which did not unregister previously
52 resized chunks, leading to a "zero size chunk" exception when
53 File::Save() was called
54 - added List::MoveSubChunk method
55
56 Version 3.1.0 (24 Nov 2006)
57
58 * packaging changes:
59 - changed deprecated copyright attribute to license;

61
62 * src/gig.cpp, src/gig.h:
63 - added support for more than one set of custom velocity splits
64 inside a region (for example different velocity split levels for
65 pedal up and pedal down)
66 - sample loop parameters are now taken from the DimensionRegion
67 instead of the wave chunk
68 - keyswitching dimension is changed from split type "normal" to
69 "bit"
70 - real support for 24 bit samples - samples are not truncated to
71 16 bits anymore
72 - support for reading of ".art" files. (Merging of .art and .gig
73 files are not implemented yet.)
74 - several fixes for the write support
75 - support for sample groups added
76
77 * src/DLS.cpp, src/DLS.h:

89
90 * general changes:

92 of Gigasampler write support)
93
94 Version 3.0.0 (28 Apr 2006)
95
96 * general changes:
97 - added write support (that is for creating and modifying RIFF, DLS and
98 gig files)
99 - loading DLS and gig files is now much more permissive, DLS and gig
100 files are now loaded even if mandatory RIFF chunks are missing
101 - fixed some memory management errors, one of them was causing a
102 crash when a multi-file gig was deallocated
103
104 * src/gig.cpp, src/gig.h:
105 - fixed the GetVelocityCutoff function, it wasn't always using the
106 VCFVelocityScale parameter when no cutoff controller was defined
107 - support for the gig v3 feature to have a number of dimension
108 splits not equal to a power of two
109 - added write support (highly experimental)
110
111 * src/DLS.cpp, src/DLS.h:
112 - fixed loading of Articulation Connections (<artl> list chunks were
113 seeked instead of ordinary <artl> data chunks)
114 - added write support (highly experimental)
115
116 * src/RIFF.cpp, src/RIFF.h:
117 - added write support
118 - Chunk::LoadChunkData() can now be called again to resize the buffer
119 after a Chunk::Resize() and before the File::Save() call to allow
120 placing the new data in the chunk's write buffer and perform the
121 resize and write operations in one rush
122
123 * src/gigdump.cpp:
124 - fixed to show the correct amount of dimension regions instead of 32
125 (patch by James Wylder)
126

135 (mandatory for 'dist-bzip2' automake option)
136
137 * src/gig.cpp, src/gig.h:
138 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
139 the extension files are read automatically when the samples are
140 loaded
141 - fixed the 24 bit decompression, the result should now be exact
142 instead of an approximation
143 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
144 function to DimensionRegion
145
146 * src/DLS.cpp, src/DLS.h:

178 articulation informations are ignored at the moment
179 (patch by Andreas Persson)
180 - added some file format compatibility checks
181 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

231
232 * packaging changes:
233 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
234 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
235 - fixed man pages automake install rule (which didn't work on Mandrake,
236 SuSE and Fedora)
237 - fixed generation of Doxygen API documentation (now also included in
238 RPM and Debian packages)
239
240 * src/gig.cpp, src/gig.h:
241 - fixed / improved accuracy of all three velocity to volume
242 transformation functions a.k.a. 'nonlinear','linear','special'
243 (patch by Andreas Persson)
244 - denormals are filtered from the velocity to volume tables
245 - bugfix for dimension region switching (wrong handling of the release
246 trigger dimension, no bit range check for dimensions of split type
247 'split_type_bit')

249 signed 7 bit to signed 8 bit)
250 - added class attribute 'Layers' to class 'gig::Region'
251 - symbol prototyping of gig::Region (fixes build failure with qsampler)
252

263 Gigasampler layers
264
265 Version 0.7.1 (2 Jul 2004)
266
267 * packaging changes:
268 - added libgig.spec and libgig.pc package configurations for generating
269 Redhat packages
270 - header files included on installation.
271 - autotools-generated files removed from CVS repository.
272 - added support for generating Debian packages
273 - version of shared library can be set in configure.in
274
275 Version 0.7.0 (3 May 2004)
276
277 * general changes:
278 - various big endian specific corrections
279 (successfully tested now on PPC)
280 - minor adjustments to avoid compile errors on some systems
281 (using now pow() instead of powl() and --pedantic g++ compiler switch)
282 - libtoolized the library
283 - added man pages for the command line tools
284 (gigextract, gigdump, dlsdump, rifftree)
285
286 * src/gig.cpp, src/gig.h:
287 - fixed bug in decompression algorithm which caused it not to detect
288 the end of a stream
289 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
290 takes the MIDI key velocity value as an argument and returns the
291 appropriate volume factor (0.0 ... 1.0) for the sample to be played
292 back, the velocity curve transformation functions used for this are
293 only an approximation so far
294 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
295 'Sample::LoopSize' which reflected wrong values
296 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
297 measured in sample points instead of byte offset
298 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
299 'Sample::FineTune'
300 - added class attribute 'Sample::LoopSize'
301 - added method GetInstrument(uint index) to class 'File'
302 - added ReadAndLoop() method to class 'Sample' which is an extension to
303 the normal Read() method to honor the sample's looping information
304 while streaming from disk
305 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
306 'eg2_ctrl_t': replaced this huge enumeration by a structure which
307 reflects the MIDI controller number in case of an ordinary control
308 change controller (this saves a huge switch-case block in the
309 application of the library user)
310 - renamed following attributes in class 'DimensionRegion':
311 'AttenuationContol' -> 'AttenuationController',
312 'InvertAttenuationControl' -> 'InvertAttenuationController',
313 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
314 - minor fix in API documentation for method GetVelocityAttenuation() in
315 class 'DimensionRegion'
316
317 * src/RIFF.cpp, src/RIFF.h:
318 - added additional API documentation
319 - minor fix in Chunk::Read() method (only a minor efficiency issue)
320
321 * src/gigdump.cpp:
322 - added printout of samples' looping informations
323
324 Version 0.6.0 (3 Nov 2003)
325
326 * initial release
