* merged libsf2 into libgig

1 Version CVS HEAD (?)
2 * SoundFont file format
3 - initial implementation
4
5 Version 3.3.0 (30 Jul 2009)
6
7 * general changes:
8 - fixed compilation with gcc 4.3
9 - fixes for building with Visual C++
10 - minor fix in configure for building DLL on Windows
11
12 * src/gig.cpp, src/gig.h:
13 - added partial support for MIDI rules, only the Controller
14 Triggered rule is supported so far
15 - bugfix: removed another iterator invalidation in DeleteSample
16 - bugfix in Sample::LoadSampleData*(): reset sample read position to
17 sample start before trying to (re)load sample data from file (#82)
18 - bugfix: EG3 depth parameter was not saved correctly
19 - fixed crash which occured when streaming a gig sample with
20 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
21
22 * src/RIFF.cpp, src/RIFF.h:
23 - bugfix: saving to the same file after the file size had been
24 increased made the file corrupt (#82)
25 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
26 is not written physically yet (#82)
27 - bugfix: saving to the same file after the file size had been
28 decreased sometimes also made the file corrupt!
29 - bugfix: undefined behavior (e.g. endless loop) when opening zero
30 length files, now throws a RIFF::Exception instead (fixes bug #121)
31 - bugfix: destructor for base class RIFF::Chunk accessed members
32 of derived class RIFF::File, which is bad, and caused crashes
33 when using Visual C++
34 - bugfix: files that contain zero length RIFF lists were not read
35 correctly (fixes #127) (bug was introduced 2009-03-13)
36
37 Version 3.2.1 (5 Dec 2007)
38
39 * src/RIFF.cpp, src/RIFF.h:
40 - avoid Windows to perform unnecessary file stream caching which would
41 decrease disk streaming performance on Windows systems otherwise
42
43 * src/gig.cpp, src/gig.h:
44 - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
45 applications to retrieve very superficial informations like amount of
46 instruments and their names in a very fast way
47
48 Version 3.2.0 (14 Oct 2007)
49
50 * packaging changes:
51 - added Mac OSX XCode project files (patch by Toshi Nagata)
52 - Dev-C++ (win32) project file is automatically updated with
53 the version info from configure.in

58 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
59 - fixed write support for big-endian systems
60 - improved handling of fixed length info strings - separate default
61 lengths can be specified for each INFO chunk
62 - added Resource::GenerateDLSID function
63 - write support fix: allow regions without mapped samples
64 - added method SetKeyRange() to the Region class which should be used
65 instead of setting the KeyRange member variable directly

67 - added SetGain() method to Sampler class
68 - fixed crash when saving a file after a sample loop was added
69
70 * src/gig.cpp, src/gig.h:
71 - fixed segmentation fault in the gig::File destructor sequence which
72 happened when gig::Group informations were accessed before
73 - fixed write support for big-endian systems
74 - defined lengths of a fixed set of info strings. These strings
75 are saved when the file is written, even if they are empty.
76 - added missing parameter initalizations in sample, region and
77 instrument constructors
78 - clear unused fields when saving samples and regions
79 - fixed write support bugs: v3 dimension limits and chunksize
80 weren't saved, leverage controller of type controlchange
81 couldn't be saved, group name list chunk was placed wrong,
82 dimension region chunks also placed wrong
83 - added initialization of some fixed info strings in file and
84 instrument
85 - write support: files created by libgig will now have the RIFF
86 chunks in correct order
87 - write support: two previously unknown fields in dimension
88 definition are now saved
89 - added constants for gig file versions
90 - write support: the 3crc and einf chunks are now created or
91 updated when a file is saved (3crc contains sample checksums,
92 einf contains file statistics)
93 - write support: DLSID is now generated on the file and the
94 instruments
95 - write support: improved the default values for dimension region
96 parameters
97 - more write support fixes: crossfade parameters were not saved,
98 v3 dimension limits were not correctly initialized and saved
99 when dimensions were added or deleted, v3 wave pool offsets were
100 not saved correctly
101 - write support: 24 bit samples can now be written
102 - write support: version 3 is now the default for new files
103 - more write support fixes: the 3ewg chunk is now bigger for v3,
104 dimension regions without mapped samples are now allowed, 3gnl
105 list in v3 files now always has 128 entries, several parameters
106 where incorrectly saved due to an operator precedence mistake
107 - DeleteSample now removes all references to the deleted sample
108 - AddDimension now copies all parameters from existing dimension
109 regions and also makes sure that the samplechannel dimension is
110 placed first in the list of dimensions.
111 - added method GetParent() to class 'DimensionRegion', which returns its
112 parent Region
113 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
114 unused areas
115 - added various setter methods to DimensionRegion class which take care
116 of updating lookup tables / caches.
117
118 * src/RIFF.cpp, src/RIFF.h:
119 - added File::SetByteOrder method
120 - Windows fix: saving a new file didn't work

124
125 Version 3.1.1 (24 Mar 2007)
126
127 * packaging changes:

129 (provided Dev-C++ + mingw project file)
130 - only export relevant files to Doxygen API documentation
131
132 * src/gig.cpp, src/gig.h:
133 - custom velocity splits now works for gig v3 files too
134 - added support for custom splits points for other dimensions than
135 velocity (gig v3 feature)
136 - added "smart midi" and "round robin keyboard" dimensions
137 - added new method File::DeleteGroupOnly() which only deletes the given
138 group but moves all its members to another group, the other method,
139 that is File::DeleteGroup() now removes not just the group, but also
140 all the samples that belong to that group
141 - fixed crash which occured on interfering File::DeleteSample() and
142 File::GetNextSample() calls (due to iterator invalidation)
143 - fixed group names which were not saved
144 - fixed group destructor which did not remove the RIFF chunk associated
145 with the group
146 - added Instrument::MoveRegion method
147 - fixed constructor for Region, which did not initialize correctly
148 when used from Instrument::AddRegion
149 - when saving, override the gig::Regions sample reference simply by
150 the region's first dimension region's sample (avoids an exception
151 when trying to save a new instrument)
152 - fixed AddDimension() method which did not fill out all mandatory
153 dimension definition fields
154
155 * src/DLS.cpp, src/DLS.h:
156 - added Instrument::MoveRegion method

158 causing an exception when trying to save a new instrument
159
160 * src/RIFF.cpp, src/RIFF.h:
161 - fixed RIFF::Chunk destructor which did not unregister previously
162 resized chunks, leading to a "zero size chunk" exception when
163 File::Save() was called
164 - added List::MoveSubChunk method
165

288 articulation informations are ignored at the moment
289 (patch by Andreas Persson)
290 - added some file format compatibility checks
291 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
292 never used, because the necessary check was made before

341
342 * packaging changes:
343 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
344 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
345 - fixed man pages automake install rule (which didn't work on Mandrake,
346 SuSE and Fedora)
347 - fixed generation of Doxygen API documentation (now also included in
348 RPM and Debian packages)
349
350 * src/gig.cpp, src/gig.h:
351 - fixed / improved accuracy of all three velocity to volume
352 transformation functions a.k.a. 'nonlinear','linear','special'
353 (patch by Andreas Persson)
354 - denormals are filtered from the velocity to volume tables
355 - bugfix for dimension region switching (wrong handling of the release
356 trigger dimension, no bit range check for dimensions of split type

378 - added libgig.spec and libgig.pc package configurations for generating
379 Redhat packages
380 - header files included on installation.
381 - autotools-generated files removed from CVS repository.
382 - added support for generating Debian packages
383 - version of shared library can be set in configure.in
384
385 Version 0.7.0 (3 May 2004)
386
387 * general changes:
388 - various big endian specific corrections
389 (successfully tested now on PPC)
390 - minor adjustments to avoid compile errors on some systems
391 (using now pow() instead of powl() and --pedantic g++ compiler switch)
392 - libtoolized the library
393 - added man pages for the command line tools
394 (gigextract, gigdump, dlsdump, rifftree)
395
396 * src/gig.cpp, src/gig.h:
397 - fixed bug in decompression algorithm which caused it not to detect
398 the end of a stream
399 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
400 takes the MIDI key velocity value as an argument and returns the
401 appropriate volume factor (0.0 ... 1.0) for the sample to be played
402 back, the velocity curve transformation functions used for this are
403 only an approximation so far
404 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
405 'Sample::LoopSize' which reflected wrong values
406 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
407 measured in sample points instead of byte offset
408 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
409 'Sample::FineTune'
410 - added class attribute 'Sample::LoopSize'
411 - added method GetInstrument(uint index) to class 'File'
412 - added ReadAndLoop() method to class 'Sample' which is an extension to
413 the normal Read() method to honor the sample's looping information
414 while streaming from disk
415 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
416 'eg2_ctrl_t': replaced this huge enumeration by a structure which
417 reflects the MIDI controller number in case of an ordinary control
418 change controller (this saves a huge switch-case block in the
419 application of the library user)
420 - renamed following attributes in class 'DimensionRegion':
421 'AttenuationContol' -> 'AttenuationController',
422 'InvertAttenuationControl' -> 'InvertAttenuationController',
423 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
424 - minor fix in API documentation for method GetVelocityAttenuation() in
425 class 'DimensionRegion'
426
427 * src/RIFF.cpp, src/RIFF.h:
428 - added additional API documentation
429 - minor fix in Chunk::Read() method (only a minor efficiency issue)
430
431 * src/gigdump.cpp:
432 - added printout of samples' looping informations
433
434 Version 0.6.0 (3 Nov 2003)
435
436 * initial release
