File size: 13000 byte(s)
* fixed exceptions which occured when trying to save a new instrument:
    - override the gig::Regions sample reference simply by the region's
      first dimension region's sample
    - fixed software info field which was wrongly stored on instruments

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - ported to Windows using native Windows functions for file IO
5 (provided Dev-C++ + mingw project file)
6 - only export relevant files to Doxygen API documentation
7
8 * src/gig.cpp, src/gig.h:
9 - custom velocity splits now works for gig v3 files too
10 - added support for custom splits points for other dimensions than
11 velocity (gig v3 feature)
12 - added "smart midi" and "round robin keyboard" dimensions
13 - added new method File::DeleteGroupOnly() which only deletes the given
14 group but moves all its members to another group, the other method,
15 that is File::DeleteGroup() now removes not just the group, but also
16 all the samples that belong to that group
17 - fixed crash which occured on interfering File::DeleteSample() and
18 File::GetNextSample() calls (due to iterator invalidation)
19 - fixed group names which were not saved
20 - fixed group destructor which did not remove the RIFF chunk associated
21 with the group
22 - added Instrument::MoveRegion method
23 - fixed constructor for Region, which did not initialize correctly
24 when used from Instrument::AddRegion
25 - when saving, override the gig::Regions sample reference simply by
26 the region's first dimension region's sample (avoids an exception
27 when trying to save a new instrument)
28
29 * src/DLS.cpp, src/DLS.h:
30 - added Instrument::MoveRegion method
31 - fixed software info field which was wrongly stored on instruments,
32 causing an exception when trying to save a new instrument
33
34 * src/RIFF.cpp, src/RIFF.h:
35 - fixed RIFF::Chunk destructor which did not unregister previously
36 resized chunks, leading to a "zero size chunk" exception when
37 File::Save() was called
38 - added List::MoveSubChunk method
39
40 Version 3.1.0 (24 Nov 2006)
41
42 * packaging changes:
43 - changed deprecated copyright attribute to license;
44 added ldconfig to post-(un)install steps on libgig.spec (RPM)
45
46 * src/gig.cpp, src/gig.h:
47 - added support for more than one set of custom velocity splits
48 inside a region (for example different velocity split levels for
49 pedal up and pedal down)

51 instead of the wave chunk
52 - keyswitching dimension is changed from split type "normal" to
53 "bit"
54 - real support for 24 bit samples - samples are not truncated to
55 16 bits anymore
56 - support for reading of ".art" files. (Merging of .art and .gig
57 files are not implemented yet.)
58 - several fixes for the write support
59 - support for sample groups added
60
61 * src/DLS.cpp, src/DLS.h:

76 of Gigasampler write support)
77
78 Version 3.0.0 (28 Apr 2006)
79
80 * general changes:
81 - added write support (that is for creating and modifying RIFF, DLS and
82 gig files)
83 - loading DLS and gig files is now much more permissive, DLS and gig
84 files are now loaded even if mandatory RIFF chunks are missing
85 - fixed some memory management errors, one of them was causing a
86 crash when a multi-file gig was deallocated
87
88 * src/gig.cpp, src/gig.h:
89 - fixed the GetVelocityCutoff function, it wasn't always using the
90 VCFVelocityScale parameter when no cutoff controller was defined
91 - support for the gig v3 feature to have a number of dimension
92 splits not equal to a power of two
93 - added write support (highly experimental)
94
95 * src/DLS.cpp, src/DLS.h:
96 - fixed loading of Articulation Connections (<artl> list chunks were
97 seeked instead of ordinary <artl> data chunks)
98 - added write support (highly experimental)
99
100 * src/RIFF.cpp, src/RIFF.h:
101 - added write support
102 - Chunk::LoadChunkData() can now be called again to resize the buffer
103 after a Chunk::Resize() and before the File::Save() call to allow
104 placing the new data in the chunk's write buffer and perform the
105 resize and write operations in one rush
106
107 * src/gigdump.cpp:
108 - fixed to show the correct amount of dimension regions instead of 32
109 (patch by James Wylder)
110

122 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
123 the extension files are read automatically when the samples are
124 loaded
125 - fixed the 24 bit decompression, the result should now be exact
126 instead of an approximation

162 articulation informations are ignored at the moment
163 (patch by Andreas Persson)
164 - added some file format compatibility checks
165 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

215
216 * packaging changes:
217 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
218 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
219 - fixed man pages automake install rule (which didn't work on Mandrake,
220 SuSE and Fedora)
221 - fixed generation of Doxygen API documentation (now also included in
222 RPM and Debian packages)
223
224 * src/gig.cpp, src/gig.h:
225 - fixed / improved accuracy of all three velocity to volume
226 transformation functions a.k.a. 'nonlinear','linear','special'
227 (patch by Andreas Persson)
228 - denormals are filtered from the velocity to volume tables
229 - bugfix for dimension region switching (wrong handling of the release
230 trigger dimension, no bit range check for dimensions of split type

248
249 Version 0.7.1 (2 Jul 2004)
250
251 * packaging changes:
252 - added libgig.spec and libgig.pc package configurations for generating
253 Redhat packages
254 - header files included on installation.
255 - autotools-generated files removed from CVS repository.
256 - added support for generating Debian packages
257 - version of shared library can be set in configure.in
258
259 Version 0.7.0 (3 May 2004)
260
261 * general changes:
262 - various big endian specific corrections
263 (successfully tested now on PPC)
264 - minor adjustments to avoid compile errors on some systems
265 (using now pow() instead of powl() and --pedantic g++ compiler switch)
266 - libtoolized the library
267 - added man pages for the command line tools
268 (gigextract, gigdump, dlsdump, rifftree)
269
270 * src/gig.cpp, src/gig.h:
271 - fixed bug in decompression algorithm which caused it not to detect
272 the end of a stream
273 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
274 takes the MIDI key velocity value as an argument and returns the
275 appropriate volume factor (0.0 ... 1.0) for the sample to be played
276 back, the velocity curve transformation functions used for this are
277 only an approximation so far
278 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
279 'Sample::LoopSize' which reflected wrong values
280 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
281 measured in sample points instead of byte offset
282 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
283 'Sample::FineTune'
284 - added class attribute 'Sample::LoopSize'
285 - added method GetInstrument(uint index) to class 'File'
286 - added ReadAndLoop() method to class 'Sample' which is an extension to
287 the normal Read() method to honor the sample's looping information
288 while streaming from disk
289 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
290 'eg2_ctrl_t': replaced this huge enumeration by a structure which
291 reflects the MIDI controller number in case of an ordinary control
292 change controller (this saves a huge switch-case block in the
293 application of the library user)
294 - renamed following attributes in class 'DimensionRegion':
295 'AttenuationContol' -> 'AttenuationController',
296 'InvertAttenuationControl' -> 'InvertAttenuationController',
297 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
298 - minor fix in API documentation for method GetVelocityAttenuation() in
299 class 'DimensionRegion'
300
301 * src/RIFF.cpp, src/RIFF.h:
302 - added additional API documentation
303 - minor fix in Chunk::Read() method (only a minor efficiency issue)
304
305 * src/gigdump.cpp:
306 - added printout of samples' looping informations
307
308 Version 0.6.0 (3 Nov 2003)
309
310 * initial release
