Sun May 13 10:34:29 2007 UTC (16 years, 10 months ago) by persson
File size: 14397 byte(s)
* added RIFF::File constructor with endianess parameter
* put pack Info::UseFixedLengthStrings, marked as deprecated, to
  ensure binary compatibility
* DLS files are always created as little-endian

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

124 splits not equal to a power of two
125 - added write support (highly experimental)
126

133 - added write support
134 - Chunk::LoadChunkData() can now be called again to resize the buffer
135 after a Chunk::Resize() and before the File::Save() call to allow

137 resize and write operations in one rush
138
139 * src/gigdump.cpp:
140 - fixed to show the correct amount of dimension regions instead of 32
141 (patch by James Wylder)

194 articulation informations are ignored at the moment
195 (patch by Andreas Persson)
196 - added some file format compatibility checks
197 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

247
248 * packaging changes:
249 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

252 SuSE and Fedora)
253 - fixed generation of Doxygen API documentation (now also included in
254 RPM and Debian packages)
255
256 * src/gig.cpp, src/gig.h:
257 - fixed / improved accuracy of all three velocity to volume
258 transformation functions a.k.a. 'nonlinear','linear','special'
259 (patch by Andreas Persson)
260 - denormals are filtered from the velocity to volume tables
261 - bugfix for dimension region switching (wrong handling of the release
262 trigger dimension, no bit range check for dimensions of split type

282
283 * packaging changes:
284 - added libgig.spec and libgig.pc package configurations for generating
285 Redhat packages
286 - header files included on installation.
287 - autotools-generated files removed from CVS repository.
288 - added support for generating Debian packages
289 - version of shared library can be set in configure.in
290
291 Version 0.7.0 (3 May 2004)
292
293 * general changes:
294 - various big endian specific corrections
295 (successfully tested now on PPC)
296 - minor adjustments to avoid compile errors on some systems
297 (using now pow() instead of powl() and --pedantic g++ compiler switch)
298 - libtoolized the library
299 - added man pages for the command line tools
300 (gigextract, gigdump, dlsdump, rifftree)
301
302 * src/gig.cpp, src/gig.h:
303 - fixed bug in decompression algorithm which caused it not to detect
304 the end of a stream
305 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
306 takes the MIDI key velocity value as an argument and returns the
307 appropriate volume factor (0.0 ... 1.0) for the sample to be played
308 back, the velocity curve transformation functions used for this are
309 only an approximation so far
310 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
311 'Sample::LoopSize' which reflected wrong values
312 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
313 measured in sample points instead of byte offset
314 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
315 'Sample::FineTune'
316 - added class attribute 'Sample::LoopSize'
317 - added method GetInstrument(uint index) to class 'File'
318 - added ReadAndLoop() method to class 'Sample' which is an extension to
319 the normal Read() method to honor the sample's looping information
320 while streaming from disk
321 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
322 'eg2_ctrl_t': replaced this huge enumeration by a structure which
323 reflects the MIDI controller number in case of an ordinary control
324 change controller (this saves a huge switch-case block in the
325 application of the library user)
326 - renamed following attributes in class 'DimensionRegion':
327 'AttenuationContol' -> 'AttenuationController',
328 'InvertAttenuationControl' -> 'InvertAttenuationController',
329 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
330 - minor fix in API documentation for method GetVelocityAttenuation() in
331 class 'DimensionRegion'
332
333 * src/RIFF.cpp, src/RIFF.h:
334 - added additional API documentation
335 - minor fix in Chunk::Read() method (only a minor efficiency issue)
336
337 * src/gigdump.cpp:
338 - added printout of samples' looping informations
339
340 Version 0.6.0 (3 Nov 2003)
341
342 * initial release
