2     * SoundFont file format
3     - initial implementation
4 persson 2100 - changed region lookup API to avoid malloc in RT threads
5 iliev 2016

12 persson 1713
13 persson 1627 * src/gig.cpp, src/gig.h:
14     - added partial support for MIDI rules, only the Controller
15     Triggered rule is supported so far
16 persson 1678 - bugfix: removed another iterator invalidation in DeleteSample
17 schoenebeck 1851 - bugfix in Sample::LoadSampleData*(): reset sample read position to
18     sample start before trying to (re)load sample data from file (#82)
19 persson 1869 - bugfix: EG3 depth parameter was not saved correctly
20 schoenebeck 1875 - fixed crash which occured when streaming a gig sample with
21     bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
22 persson 1627
23 persson 1678 * 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 schoenebeck 1851 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
27     is not written physically yet (#82)
28 persson 1859 - bugfix: saving to the same file after the file size had been
29     decreased sometimes also made the file corrupt!
30 schoenebeck 1863 - bugfix: undefined behavior (e.g. endless loop) when opening zero
31     length files, now throws a RIFF::Exception instead (fixes bug #121)
32 persson 1869 - 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++

36     correctly (fixes #127) (bug was introduced 2009-03-13)

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)

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
