* improved handling of fixed length info strings

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
19 Version 3.1.1 (24 Mar 2007)
20
21 * packaging changes:
22 - ported to Windows using native Windows functions for file IO
23 (provided Dev-C++ + mingw project file)
24 - only export relevant files to Doxygen API documentation
25
26 * src/gig.cpp, src/gig.h:
27 - custom velocity splits now works for gig v3 files too
28 - added support for custom splits points for other dimensions than
29 velocity (gig v3 feature)
30 - added "smart midi" and "round robin keyboard" dimensions
31 - added new method File::DeleteGroupOnly() which only deletes the given
32 group but moves all its members to another group, the other method,
33 that is File::DeleteGroup() now removes not just the group, but also
34 all the samples that belong to that group
35 - fixed crash which occured on interfering File::DeleteSample() and
36 File::GetNextSample() calls (due to iterator invalidation)
37 - fixed group names which were not saved
38 - fixed group destructor which did not remove the RIFF chunk associated
39 with the group
40 - added Instrument::MoveRegion method
41 - fixed constructor for Region, which did not initialize correctly
42 when used from Instrument::AddRegion
43 - when saving, override the gig::Regions sample reference simply by
44 the region's first dimension region's sample (avoids an exception
45 when trying to save a new instrument)
46 - fixed AddDimension() method which did not fill out all mandatory
47 dimension definition fields
48
49 * src/DLS.cpp, src/DLS.h:
50 - added Instrument::MoveRegion method
51 - fixed software info field which was wrongly stored on instruments,
52 causing an exception when trying to save a new instrument
53
54 * src/RIFF.cpp, src/RIFF.h:
55 - fixed RIFF::Chunk destructor which did not unregister previously
56 resized chunks, leading to a "zero size chunk" exception when
57 File::Save() was called
58 - added List::MoveSubChunk method
59
60 Version 3.1.0 (24 Nov 2006)
61
62 * packaging changes:
63 - changed deprecated copyright attribute to license;
64 added ldconfig to post-(un)install steps on libgig.spec (RPM)
65
66 * src/gig.cpp, src/gig.h:
67 - added support for more than one set of custom velocity splits
68 inside a region (for example different velocity split levels for
69 pedal up and pedal down)
70 - sample loop parameters are now taken from the DimensionRegion
71 instead of the wave chunk
72 - keyswitching dimension is changed from split type "normal" to
73 "bit"
74 - real support for 24 bit samples - samples are not truncated to
75 16 bits anymore
76 - support for reading of ".art" files. (Merging of .art and .gig
77 files are not implemented yet.)
78 - several fixes for the write support
79 - support for sample groups added
80
81 * src/DLS.cpp, src/DLS.h:
82 - support for reading of ".art" files
83 - removed incorrect use of memccpy in the write support (patch by

88 - real support for 24 bit samples
89
90 * src/gigdump.cpp:
91 - print global file informations
92 - print sample groups
93
94 * general changes:
95 - added CPPUnit test cases (at the moment primarily for automatic check
96 of Gigasampler write support)
97
98 Version 3.0.0 (28 Apr 2006)
99
100 * general changes:
101 - added write support (that is for creating and modifying RIFF, DLS and
102 gig files)
103 - loading DLS and gig files is now much more permissive, DLS and gig
104 files are now loaded even if mandatory RIFF chunks are missing
105 - fixed some memory management errors, one of them was causing a
106 crash when a multi-file gig was deallocated
107
108 * src/gig.cpp, src/gig.h:
109 - fixed the GetVelocityCutoff function, it wasn't always using the
110 VCFVelocityScale parameter when no cutoff controller was defined
111 - support for the gig v3 feature to have a number of dimension
112 splits not equal to a power of two
113 - added write support (highly experimental)
114
115 * src/DLS.cpp, src/DLS.h:
116 - fixed loading of Articulation Connections (<artl> list chunks were
117 seeked instead of ordinary <artl> data chunks)
118 - added write support (highly experimental)
119
120 * src/RIFF.cpp, src/RIFF.h:
121 - added write support
122 - Chunk::LoadChunkData() can now be called again to resize the buffer
123 after a Chunk::Resize() and before the File::Save() call to allow
124 placing the new data in the chunk's write buffer and perform the
125 resize and write operations in one rush
126
127 * src/gigdump.cpp:
128 - fixed to show the correct amount of dimension regions instead of 32
129 (patch by James Wylder)
130

140
141 * src/gig.cpp, src/gig.h:
142 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
143 the extension files are read automatically when the samples are
144 loaded
145 - fixed the 24 bit decompression, the result should now be exact
146 instead of an approximation
147 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
148 function to DimensionRegion
149
150 * src/DLS.cpp, src/DLS.h:
151 - the upper bits of the pool table indices are read (used as
152 extension file numbers for gig v3)

182 articulation informations are ignored at the moment
183 (patch by Andreas Persson)
184 - added some file format compatibility checks
185 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

268
269 Version 0.7.1 (2 Jul 2004)
270
271 * packaging changes:
272 - added libgig.spec and libgig.pc package configurations for generating
273 Redhat packages
274 - header files included on installation.
275 - autotools-generated files removed from CVS repository.
276 - added support for generating Debian packages
277 - version of shared library can be set in configure.in
278
279 Version 0.7.0 (3 May 2004)
280
281 * general changes:
282 - various big endian specific corrections
283 (successfully tested now on PPC)
284 - minor adjustments to avoid compile errors on some systems
285 (using now pow() instead of powl() and --pedantic g++ compiler switch)
286 - libtoolized the library
287 - added man pages for the command line tools
288 (gigextract, gigdump, dlsdump, rifftree)
289
290 * src/gig.cpp, src/gig.h:
291 - fixed bug in decompression algorithm which caused it not to detect
292 the end of a stream
293 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
294 takes the MIDI key velocity value as an argument and returns the
295 appropriate volume factor (0.0 ... 1.0) for the sample to be played
296 back, the velocity curve transformation functions used for this are
297 only an approximation so far
298 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
299 'Sample::LoopSize' which reflected wrong values
300 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
301 measured in sample points instead of byte offset
302 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
303 'Sample::FineTune'
304 - added class attribute 'Sample::LoopSize'
305 - added method GetInstrument(uint index) to class 'File'
306 - added ReadAndLoop() method to class 'Sample' which is an extension to
307 the normal Read() method to honor the sample's looping information
308 while streaming from disk
309 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
310 'eg2_ctrl_t': replaced this huge enumeration by a structure which
311 reflects the MIDI controller number in case of an ordinary control
312 change controller (this saves a huge switch-case block in the
313 application of the library user)
314 - renamed following attributes in class 'DimensionRegion':
315 'AttenuationContol' -> 'AttenuationController',
316 'InvertAttenuationControl' -> 'InvertAttenuationController',
317 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
318 - minor fix in API documentation for method GetVelocityAttenuation() in
319 class 'DimensionRegion'
320
321 * src/RIFF.cpp, src/RIFF.h:
322 - added additional API documentation
323 - minor fix in Chunk::Read() method (only a minor efficiency issue)
324
325 * src/gigdump.cpp:
326 - added printout of samples' looping informations
327
328 Version 0.6.0 (3 Nov 2003)
329
330 * initial release
