* improved the default values for dimension region parameters

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 - write support: improved the default values for dimension region
41 parameters
42
43 * src/RIFF.cpp, src/RIFF.h:
44 - added File::SetByteOrder method
45
46 Version 3.1.1 (24 Mar 2007)
47
48 * packaging changes:
49 - ported to Windows using native Windows functions for file IO
50 (provided Dev-C++ + mingw project file)
51 - only export relevant files to Doxygen API documentation
52
53 * src/gig.cpp, src/gig.h:
54 - custom velocity splits now works for gig v3 files too
55 - added support for custom splits points for other dimensions than
56 velocity (gig v3 feature)
57 - added "smart midi" and "round robin keyboard" dimensions
58 - added new method File::DeleteGroupOnly() which only deletes the given
59 group but moves all its members to another group, the other method,
60 that is File::DeleteGroup() now removes not just the group, but also
61 all the samples that belong to that group
62 - fixed crash which occured on interfering File::DeleteSample() and
63 File::GetNextSample() calls (due to iterator invalidation)
64 - fixed group names which were not saved
65 - fixed group destructor which did not remove the RIFF chunk associated
66 with the group
67 - added Instrument::MoveRegion method
68 - fixed constructor for Region, which did not initialize correctly
69 when used from Instrument::AddRegion
70 - when saving, override the gig::Regions sample reference simply by
71 the region's first dimension region's sample (avoids an exception
72 when trying to save a new instrument)
73 - fixed AddDimension() method which did not fill out all mandatory
74 dimension definition fields
75
76 * src/DLS.cpp, src/DLS.h:
77 - added Instrument::MoveRegion method
78 - fixed software info field which was wrongly stored on instruments,
79 causing an exception when trying to save a new instrument
80
81 * src/RIFF.cpp, src/RIFF.h:
82 - fixed RIFF::Chunk destructor which did not unregister previously
83 resized chunks, leading to a "zero size chunk" exception when
84 File::Save() was called
85 - added List::MoveSubChunk method
86
87 Version 3.1.0 (24 Nov 2006)
88

95 inside a region (for example different velocity split levels for
96 pedal up and pedal down)
97 - sample loop parameters are now taken from the DimensionRegion
98 instead of the wave chunk
99 - keyswitching dimension is changed from split type "normal" to
100 "bit"

138 - support for the gig v3 feature to have a number of dimension
139 splits not equal to a power of two
140 - added write support (highly experimental)
141

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

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

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

282 - symbol prototyping of gig::Region (fixes build failure with qsampler)
283

296 Version 0.7.1 (2 Jul 2004)
297
298 * packaging changes:
299 - added libgig.spec and libgig.pc package configurations for generating
300 Redhat packages
301 - header files included on installation.
302 - autotools-generated files removed from CVS repository.
303 - added support for generating Debian packages
304 - version of shared library can be set in configure.in
305
306 Version 0.7.0 (3 May 2004)
307
308 * general changes:
309 - various big endian specific corrections
310 (successfully tested now on PPC)
311 - minor adjustments to avoid compile errors on some systems
312 (using now pow() instead of powl() and --pedantic g++ compiler switch)
313 - libtoolized the library
314 - added man pages for the command line tools
315 (gigextract, gigdump, dlsdump, rifftree)
316
317 * src/gig.cpp, src/gig.h:
318 - fixed bug in decompression algorithm which caused it not to detect
319 the end of a stream
320 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
321 takes the MIDI key velocity value as an argument and returns the
322 appropriate volume factor (0.0 ... 1.0) for the sample to be played
323 back, the velocity curve transformation functions used for this are
324 only an approximation so far
325 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
326 'Sample::LoopSize' which reflected wrong values
327 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
328 measured in sample points instead of byte offset
329 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
330 'Sample::FineTune'
331 - added class attribute 'Sample::LoopSize'
332 - added method GetInstrument(uint index) to class 'File'
333 - added ReadAndLoop() method to class 'Sample' which is an extension to
334 the normal Read() method to honor the sample's looping information
335 while streaming from disk
336 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
337 'eg2_ctrl_t': replaced this huge enumeration by a structure which
338 reflects the MIDI controller number in case of an ordinary control
339 change controller (this saves a huge switch-case block in the
340 application of the library user)
341 - renamed following attributes in class 'DimensionRegion':
342 'AttenuationContol' -> 'AttenuationController',
343 'InvertAttenuationControl' -> 'InvertAttenuationController',
344 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
345 - minor fix in API documentation for method GetVelocityAttenuation() in
346 class 'DimensionRegion'
347
348 * src/RIFF.cpp, src/RIFF.h:
349 - added additional API documentation
350 - minor fix in Chunk::Read() method (only a minor efficiency issue)
351
352 * src/gigdump.cpp:
353 - added printout of samples' looping informations
354
355 Version 0.6.0 (3 Nov 2003)
356
357 * initial release
