Thu Aug 2 14:12:55 2007 UTC (16 years, 7 months ago) by persson
File size: 15950 byte(s)
* write support fixes: allow regions/dimension regions without mapped
  samples, 3gnl in v3 files now always has 128 entries, several
  parameters where incorrectly saved due to an operator precedence
  mistake
* DeleteSample now removes all references to the deleted sample

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 - write support fix: allow regions without mapped samples
15
16 * src/gig.cpp, src/gig.h:
17 - fixed segmentation fault in the gig::File destructor sequence which
18 happened when gig::Group informations were accessed before
19 - fixed write support for big-endian systems
20 - defined lengths of a fixed set of info strings. These strings
21 are saved when the file is written, even if they are empty.
22 - added missing parameter initalizations in sample, region and
23 instrument constructors
24 - clear unused fields when saving samples and regions
25 - fixed write support bugs: v3 dimension limits and chunksize
26 weren't saved, leverage controller of type controlchange
27 couldn't be saved, group name list chunk was placed wrong,
28 dimension region chunks also placed wrong
29 - added initialization of some fixed info strings in file and
30 instrument
31 - write support: files created by libgig will now have the RIFF
32 chunks in correct order
33 - write support: two previously unknown fields in dimension
34 definition are now saved
35 - added constants for gig file versions
36 - write support: the 3crc and einf chunks are now created or
37 updated when a file is saved (3crc contains sample checksums,
38 einf contains file statistics)
39 - write support: DLSID is now generated on the file and the
40 instruments
41 - write support: improved the default values for dimension region
42 parameters
43 - more write support fixes: crossfade parameters were not saved,
44 v3 dimension limits were not correctly initialized and saved
45 when dimensions were added or deleted, v3 wave pool offsets were
46 not saved correctly
47 - write support: 24 bit samples can now be written
48 - write support: version 3 is now the default for new files
49 - more write support fixes: the 3ewg chunk is now bigger for v3,
50 dimension regions without mapped samples are now allowed, 3gnl
51 list in v3 files now always has 128 entries, several parameters
52 where incorrectly saved due to an operator precedence mistake
53 - DeleteSample now removes all references to the deleted sample
54
55 * src/RIFF.cpp, src/RIFF.h:
56 - added File::SetByteOrder method
57
58 * src/gigdump.cpp:
59 - added some missing dimension strings
60
61 Version 3.1.1 (24 Mar 2007)
62
63 * packaging changes:
64 - ported to Windows using native Windows functions for file IO
65 (provided Dev-C++ + mingw project file)
66 - only export relevant files to Doxygen API documentation
67
68 * src/gig.cpp, src/gig.h:
69 - custom velocity splits now works for gig v3 files too
70 - added support for custom splits points for other dimensions than
71 velocity (gig v3 feature)
72 - added "smart midi" and "round robin keyboard" dimensions
73 - added new method File::DeleteGroupOnly() which only deletes the given
74 group but moves all its members to another group, the other method,
75 that is File::DeleteGroup() now removes not just the group, but also
76 all the samples that belong to that group
77 - fixed crash which occured on interfering File::DeleteSample() and
78 File::GetNextSample() calls (due to iterator invalidation)
79 - fixed group names which were not saved
80 - fixed group destructor which did not remove the RIFF chunk associated
81 with the group
82 - added Instrument::MoveRegion method
83 - fixed constructor for Region, which did not initialize correctly
84 when used from Instrument::AddRegion
85 - when saving, override the gig::Regions sample reference simply by
86 the region's first dimension region's sample (avoids an exception
87 when trying to save a new instrument)
88 - fixed AddDimension() method which did not fill out all mandatory
89 dimension definition fields
90
91 * src/DLS.cpp, src/DLS.h:
92 - added Instrument::MoveRegion method
93 - fixed software info field which was wrongly stored on instruments,
94 causing an exception when trying to save a new instrument
95
96 * src/RIFF.cpp, src/RIFF.h:
97 - fixed RIFF::Chunk destructor which did not unregister previously
98 resized chunks, leading to a "zero size chunk" exception when
99 File::Save() was called
100 - added List::MoveSubChunk method
101
102 Version 3.1.0 (24 Nov 2006)

225 (patch by Andreas Persson)
226 - added some file format compatibility checks
227 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

277
278 * packaging changes:
279 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
280 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
281 - fixed man pages automake install rule (which didn't work on Mandrake,
282 SuSE and Fedora)
283 - fixed generation of Doxygen API documentation (now also included in
284 RPM and Debian packages)
285
286 * src/gig.cpp, src/gig.h:
287 - fixed / improved accuracy of all three velocity to volume
288 transformation functions a.k.a. 'nonlinear','linear','special'
289 (patch by Andreas Persson)
290 - denormals are filtered from the velocity to volume tables
291 - bugfix for dimension region switching (wrong handling of the release
292 trigger dimension, no bit range check for dimensions of split type

297 - symbol prototyping of gig::Region (fixes build failure with qsampler)
298

311 Version 0.7.1 (2 Jul 2004)
312
313 * packaging changes:
314 - added libgig.spec and libgig.pc package configurations for generating
315 Redhat packages
316 - header files included on installation.
317 - autotools-generated files removed from CVS repository.
318 - added support for generating Debian packages
319 - version of shared library can be set in configure.in
320
321 Version 0.7.0 (3 May 2004)
322
323 * general changes:
324 - various big endian specific corrections
325 (successfully tested now on PPC)
326 - minor adjustments to avoid compile errors on some systems
327 (using now pow() instead of powl() and --pedantic g++ compiler switch)
328 - libtoolized the library
329 - added man pages for the command line tools
330 (gigextract, gigdump, dlsdump, rifftree)
331
332 * src/gig.cpp, src/gig.h:
333 - fixed bug in decompression algorithm which caused it not to detect
334 the end of a stream
335 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
336 takes the MIDI key velocity value as an argument and returns the
337 appropriate volume factor (0.0 ... 1.0) for the sample to be played
338 back, the velocity curve transformation functions used for this are
339 only an approximation so far
340 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
341 'Sample::LoopSize' which reflected wrong values
342 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
343 measured in sample points instead of byte offset
344 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
345 'Sample::FineTune'
346 - added class attribute 'Sample::LoopSize'
347 - added method GetInstrument(uint index) to class 'File'
348 - added ReadAndLoop() method to class 'Sample' which is an extension to
349 the normal Read() method to honor the sample's looping information
350 while streaming from disk
351 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
352 'eg2_ctrl_t': replaced this huge enumeration by a structure which
353 reflects the MIDI controller number in case of an ordinary control
354 change controller (this saves a huge switch-case block in the
355 application of the library user)
356 - renamed following attributes in class 'DimensionRegion':
357 'AttenuationContol' -> 'AttenuationController',
358 'InvertAttenuationControl' -> 'InvertAttenuationController',
359 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
360 - minor fix in API documentation for method GetVelocityAttenuation() in
361 class 'DimensionRegion'
362
363 * src/RIFF.cpp, src/RIFF.h:
364 - added additional API documentation
365 - minor fix in Chunk::Read() method (only a minor efficiency issue)
366
367 * src/gigdump.cpp:
368 - added printout of samples' looping informations
369
370 Version 0.6.0 (3 Nov 2003)
371
372 * initial release
