* sf2: changed region lookup API to avoid malloc in RT threads

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

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

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

125
126 Version 3.1.1 (24 Mar 2007)
127

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

159 causing an exception when trying to save a new instrument
160
161 * src/RIFF.cpp, src/RIFF.h:
162 - fixed RIFF::Chunk destructor which did not unregister previously
163 resized chunks, leading to a "zero size chunk" exception when
164 File::Save() was called
165 - added List::MoveSubChunk method
166

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

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

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