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

37     of derived class RIFF::File, which is bad, and caused crashes
38     when using Visual C++

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

393     - various big endian specific corrections
394     (successfully tested now on PPC)

396     (using now pow() instead of powl() and --pedantic g++ compiler switch)
397     - libtoolized the library
398     - added man pages for the command line tools
399     (gigextract, gigdump, dlsdump, rifftree)

402     - fixed bug in decompression algorithm which caused it not to detect
403     the end of a stream
404     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
405     takes the MIDI key velocity value as an argument and returns the
406     appropriate volume factor (0.0 ... 1.0) for the sample to be played
407     back, the velocity curve transformation functions used for this are
408     only an approximation so far
409     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
410     'Sample::LoopSize' which reflected wrong values
411     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
412     measured in sample points instead of byte offset
413     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
414     'Sample::FineTune'
415     - added class attribute 'Sample::LoopSize'
416     - added method GetInstrument(uint index) to class 'File'
417     - added ReadAndLoop() method to class 'Sample' which is an extension to
418     the normal Read() method to honor the sample's looping information
419     while streaming from disk
420     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
421     'eg2_ctrl_t': replaced this huge enumeration by a structure which
422     reflects the MIDI controller number in case of an ordinary control
423     change controller (this saves a huge switch-case block in the
424     application of the library user)
425     - renamed following attributes in class 'DimensionRegion':
426     'AttenuationContol' -> 'AttenuationController',
427     'InvertAttenuationControl' -> 'InvertAttenuationController',
428     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
429     - minor fix in API documentation for method GetVelocityAttenuation() in
430     class 'DimensionRegion'
431    
432     * src/RIFF.cpp, src/RIFF.h:
433     - added additional API documentation
434     - minor fix in Chunk::Read() method (only a minor efficiency issue)
435    
436     * src/gigdump.cpp:
437     - added printout of samples' looping informations
