* added DLSID support

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 - added Resource::GenerateDLSID function
14
15 * src/gig.cpp, src/gig.h:
16 - fixed segmentation fault in the gig::File destructor sequence which
17 happened when gig::Group informations were accessed before
18 - fixed write support for big-endian systems
19 - defined lengths of a fixed set of info strings. These strings
20 are saved when the file is written, even if they are empty.
21 - added missing parameter initalizations in sample, region and
22 instrument constructors
23 - clear unused fields when saving samples and regions
24 - fixed write support bugs: v3 dimension limits and chunksize
25 weren't saved, leverage controller of type controlchange
26 couldn't be saved, group name list chunk was placed wrong,
27 dimension region chunks also placed wrong
28 - added initialization of some fixed info strings in file and
29 instrument
30 - write support: files created by libgig will now have the RIFF
31 chunks in correct order
32 - write support: two previously unknown fields in dimension
33 definition are now saved
34 - added constants for gig file versions
35 - write support: the 3crc and einf chunks are now created or
36 updated when a file is saved (3crc contains sample checksums,
37 einf contains file statistics)
38 - write support: DLSID is now generated on the file and the
39 instruments
40
41 * src/RIFF.cpp, src/RIFF.h:
42 - added File::SetByteOrder method
43
44 Version 3.1.1 (24 Mar 2007)
45
46 * packaging changes:
47 - ported to Windows using native Windows functions for file IO
48 (provided Dev-C++ + mingw project file)
49 - only export relevant files to Doxygen API documentation
50
51 * src/gig.cpp, src/gig.h:
52 - custom velocity splits now works for gig v3 files too
53 - added support for custom splits points for other dimensions than
54 velocity (gig v3 feature)
55 - added "smart midi" and "round robin keyboard" dimensions
56 - added new method File::DeleteGroupOnly() which only deletes the given
57 group but moves all its members to another group, the other method,
58 that is File::DeleteGroup() now removes not just the group, but also
59 all the samples that belong to that group
60 - fixed crash which occured on interfering File::DeleteSample() and
61 File::GetNextSample() calls (due to iterator invalidation)
62 - fixed group names which were not saved
63 - fixed group destructor which did not remove the RIFF chunk associated
64 with the group
65 - added Instrument::MoveRegion method
66 - fixed constructor for Region, which did not initialize correctly
67 when used from Instrument::AddRegion
68 - when saving, override the gig::Regions sample reference simply by
69 the region's first dimension region's sample (avoids an exception
70 when trying to save a new instrument)
71 - fixed AddDimension() method which did not fill out all mandatory
72 dimension definition fields
73
74 * src/DLS.cpp, src/DLS.h:
75 - added Instrument::MoveRegion method
76 - fixed software info field which was wrongly stored on instruments,
77 causing an exception when trying to save a new instrument
78
79 * src/RIFF.cpp, src/RIFF.h:
80 - fixed RIFF::Chunk destructor which did not unregister previously
81 resized chunks, leading to a "zero size chunk" exception when
82 File::Save() was called
83 - added List::MoveSubChunk method
84
85 Version 3.1.0 (24 Nov 2006)
86
87 * packaging changes:
88 - changed deprecated copyright attribute to license;
89 added ldconfig to post-(un)install steps on libgig.spec (RPM)
90

93 inside a region (for example different velocity split levels for
94 pedal up and pedal down)

96 instead of the wave chunk
97 - keyswitching dimension is changed from split type "normal" to
98 "bit"
99 - real support for 24 bit samples - samples are not truncated to
100 16 bits anymore
101 - support for reading of ".art" files. (Merging of .art and .gig

129 files are now loaded even if mandatory RIFF chunks are missing
130 - fixed some memory management errors, one of them was causing a
131 crash when a multi-file gig was deallocated

134 - fixed the GetVelocityCutoff function, it wasn't always using the
135 VCFVelocityScale parameter when no cutoff controller was defined
136 - support for the gig v3 feature to have a number of dimension
137 splits not equal to a power of two
138 - added write support (highly experimental)
139
140 * src/DLS.cpp, src/DLS.h:

207 articulation informations are ignored at the moment
208 (patch by Andreas Persson)
209 - added some file format compatibility checks
210 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

260
261 * packaging changes:
262 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

265 SuSE and Fedora)
266 - fixed generation of Doxygen API documentation (now also included in
267 RPM and Debian packages)
268
269 * src/gig.cpp, src/gig.h:
270 - fixed / improved accuracy of all three velocity to volume
271 transformation functions a.k.a. 'nonlinear','linear','special'
272 (patch by Andreas Persson)
273 - denormals are filtered from the velocity to volume tables
274 - bugfix for dimension region switching (wrong handling of the release
275 trigger dimension, no bit range check for dimensions of split type

280 - symbol prototyping of gig::Region (fixes build failure with qsampler)
281
282 * src/gigextract.cpp:

294 Version 0.7.1 (2 Jul 2004)
295
296 * packaging changes:
297 - added libgig.spec and libgig.pc package configurations for generating
298 Redhat packages
299 - header files included on installation.
300 - autotools-generated files removed from CVS repository.
301 - added support for generating Debian packages
302 - version of shared library can be set in configure.in
303
304 Version 0.7.0 (3 May 2004)
305
306 * general changes:
307 - various big endian specific corrections
308 (successfully tested now on PPC)
309 - minor adjustments to avoid compile errors on some systems
310 (using now pow() instead of powl() and --pedantic g++ compiler switch)
311 - libtoolized the library
312 - added man pages for the command line tools
313 (gigextract, gigdump, dlsdump, rifftree)
314
315 * src/gig.cpp, src/gig.h:
316 - fixed bug in decompression algorithm which caused it not to detect
317 the end of a stream
318 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
319 takes the MIDI key velocity value as an argument and returns the
320 appropriate volume factor (0.0 ... 1.0) for the sample to be played
321 back, the velocity curve transformation functions used for this are
322 only an approximation so far
323 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
324 'Sample::LoopSize' which reflected wrong values
325 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
326 measured in sample points instead of byte offset
327 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
328 'Sample::FineTune'
329 - added class attribute 'Sample::LoopSize'
330 - added method GetInstrument(uint index) to class 'File'
331 - added ReadAndLoop() method to class 'Sample' which is an extension to
332 the normal Read() method to honor the sample's looping information
333 while streaming from disk
334 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
335 'eg2_ctrl_t': replaced this huge enumeration by a structure which
336 reflects the MIDI controller number in case of an ordinary control
337 change controller (this saves a huge switch-case block in the
338 application of the library user)
339 - renamed following attributes in class 'DimensionRegion':
340 'AttenuationContol' -> 'AttenuationController',
341 'InvertAttenuationControl' -> 'InvertAttenuationController',
342 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
343 - minor fix in API documentation for method GetVelocityAttenuation() in
344 class 'DimensionRegion'
345
346 * src/RIFF.cpp, src/RIFF.h:
347 - added additional API documentation
348 - minor fix in Chunk::Read() method (only a minor efficiency issue)
349
350 * src/gigdump.cpp:
351 - added printout of samples' looping informations
352
353 Version 0.6.0 (3 Nov 2003)
354
355 * initial release
