22 (patch by Ryan Schmidt)
23
24 * SoundFont file format:
25 - initial implementation
26 - changed region lookup API to avoid malloc in RT threads
27 - fixed GetEG1Sustain which didn't return correct value
28 - bugfix: GetPan always returned -1, 0 or 1
29

31 - initial support for sample based instruments in KORG's file format
32 (.KMP and .KSF files)
33
34 * AKAI file format:
35 - Added Linux/POSIX ported version of libakai. Note that libakai is released
36 under LGPL terms while libgig is released under GPL terms. To handle this
37 license difference appropriately the AKAI support part is built as
38 separate DLL (.so file).
39 - Fixed Mac OSX support so that the Akai lib files and tools compile without
40 any exotic third party libraries.
41 - Fixed various compilation errors for Windows.
42 - POSIX fix: open() requires third (mode) argument if used with O_CREAT
43 (fixes #219).
44
45 * src/gig.cpp:
46 - bugfix: VCF velocity dynamic range and VCF velocity curve
47 weren't saved correctly

70 - added new method Region::GetDimensionRegionIndexByValue()
71 - added new method Script::GetGroup()
72 - added new method Region::SetDimensionType()

75 new one being dropped after save operation and the gig file being tainted
76 (chunks at wrong location in the RIFF tree).
77 - Added new method Instrument::MoveTo() which allows to rearrange the order
78 of instruments within the same gig file.

86 - added inline helper methods overlaps() for struct range_t
87 - Added support for custom progress notification while saving to DLS file.
88 - Bugfix: Adding a new region in between two existing regions caused the
89 new one being dropped after save operation and the gig file being tainted
90 (chunks at wrong location in the RIFF tree).
91
92 * src/RIFF.cpp, src/RIFF.h:
93 - bugfix: avoid calling read() with count 0 when writing a file,
94 as this may hang on some systems
95 - fixed memory leak and memory handling errors when file loading

107 one allows to move the subchunk from the current list to another list
108 - POSIX: only assume -1 result value as error on open() calls
109 - POSIX: show operating system's error reason if opening a file failed
110 - Added support for custom progress notification while saving to RIFF file.
111 - Fixed embarrassing old bug: POSIX read() errors were never detected on

136 - fixed crash which occured when streaming a gig sample with
137 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
138
139 * src/RIFF.cpp, src/RIFF.h:

194 instrument constructors
195 - clear unused fields when saving samples and regions
196 - fixed write support bugs: v3 dimension limits and chunksize

216 when dimensions were added or deleted, v3 wave pool offsets were
217 not saved correctly
218 - write support: 24 bit samples can now be written

262 with the group
263 - added Instrument::MoveRegion method
264 - fixed constructor for Region, which did not initialize correctly
265 when used from Instrument::AddRegion
266 - when saving, override the gig::Regions sample reference simply by
267 the region's first dimension region's sample (avoids an exception
268 when trying to save a new instrument)

517 takes the MIDI key velocity value as an argument and returns the
518 appropriate volume factor (0.0 ... 1.0) for the sample to be played
519 back, the velocity curve transformation functions used for this are
520 only an approximation so far
521 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
522 'Sample::LoopSize' which reflected wrong values
523 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
524 measured in sample points instead of byte offset
525 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
526 'Sample::FineTune'
527 - added class attribute 'Sample::LoopSize'
528 - added method GetInstrument(uint index) to class 'File'
529 - added ReadAndLoop() method to class 'Sample' which is an extension to
530 the normal Read() method to honor the sample's looping information
531 while streaming from disk
532 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
533 'eg2_ctrl_t': replaced this huge enumeration by a structure which
534 reflects the MIDI controller number in case of an ordinary control
535 change controller (this saves a huge switch-case block in the
536 application of the library user)
537 - renamed following attributes in class 'DimensionRegion':
538 'AttenuationContol' -> 'AttenuationController',
539 'InvertAttenuationControl' -> 'InvertAttenuationController',
540 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
541 - minor fix in API documentation for method GetVelocityAttenuation() in
542 class 'DimensionRegion'
543
544 * src/RIFF.cpp, src/RIFF.h:
545 - added additional API documentation
546 - minor fix in Chunk::Read() method (only a minor efficiency issue)
547
548 * src/gigdump.cpp:
549 - added printout of samples' looping informations
550
551 Version 0.6.0 (3 Nov 2003)
