File size: 24950 byte(s)
* gig: Added new method Instrument::MoveTo() which allows to rearrange the
  order of instruments within the same gig file.
* Bumped version (3.3.0.svn26).

1 Version CVS HEAD (?)
2 * general changes:
3 - minor Makefile fix for parallel make
4 - Mac OS X: link with CoreFoundation (for the UUID function)
5 - removed gcc 4.7 warnings
6 - modernized configure script
7 - removed usage of deprecated Automake variable INCLUDES
8 - added new command line tool "gigmerge"
9 - added "const" keyword to several methods
10 - added new command line tool "gig2mono"
11 - added man page for "sf2dump"
12 - added new command line tool "korgdump" (and a man page for it)
13 - added new command line tool "korg2gig" (and a man page for it)
14 - moved source files of command line tools to new subdir src/tools
15 - libgig.so and libakai.so files are now installed under
16 $(prefix)/lib/libgig/ by default.
17 - Header files are now installed under $(prefix)/include/libgig/ by default.
18 - Fixed various packaging issues regarding installation directories
19 (fixes #218).
20 - added new command line tool "gig2stereo" (and a man page for it)
21
22 * SoundFont file format:
23 - initial implementation
24 - changed region lookup API to avoid malloc in RT threads
25 - fixed GetEG1Sustain which didn't return correct value
26 - bugfix: GetPan always returned -1, 0 or 1
27
28 * KORG file format:
29 - initial support for sample based instruments in KORG's file format
30 (.KMP and .KSF files)
31
32 * AKAI file format:
33 - Added Linux/POSIX ported version of libakai. Note that libakai is released
34 under LGPL terms while libgig is released under GPL terms. To handle this
35 license difference appropriately the AKAI support part is built as
36 separate DLL (.so file).
37 - Fixed Mac OSX support so that the Akai lib files and tools compile without
38 any exotic third party libraries.
39 - Fixed various compilation errors for Windows.
40 - POSIX fix: open() requires third (mode) argument if used with O_CREAT
41 (fixes #219).

86 - Bugfix: Adding a new region in between two existing regions caused the
87 new one being dropped after save operation and the gig file being tainted
88 (chunks at wrong location in the RIFF tree).
89
90 * src/RIFF.cpp, src/RIFF.h:
91 - bugfix: avoid calling read() with count 0 when writing a file,
92 as this may hang on some systems
93 - fixed memory leak and memory handling errors when file loading

106 - POSIX: only assume -1 result value as error on open() calls
107 - POSIX: show operating system's error reason if opening a file failed
108 - Added support for custom progress notification while saving to RIFF file.

134 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
135
136 * src/RIFF.cpp, src/RIFF.h:
137 - bugfix: saving to the same file after the file size had been

191 instrument constructors
192 - clear unused fields when saving samples and regions
193 - fixed write support bugs: v3 dimension limits and chunksize

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

219 list in v3 files now always has 128 entries, several parameters
220 where incorrectly saved due to an operator precedence mistake
221 - DeleteSample now removes all references to the deleted sample
222 - AddDimension now copies all parameters from existing dimension
223 regions and also makes sure that the samplechannel dimension is
224 placed first in the list of dimensions.

463
464 * src/gig.cpp, src/gig.h:
465 - fixed / improved accuracy of all three velocity to volume
466 transformation functions a.k.a. 'nonlinear','linear','special'
467 (patch by Andreas Persson)

500
501 * general changes:
502 - various big endian specific corrections

511 - fixed bug in decompression algorithm which caused it not to detect
512 the end of a stream
513 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
514 takes the MIDI key velocity value as an argument and returns the
515 appropriate volume factor (0.0 ... 1.0) for the sample to be played
516 back, the velocity curve transformation functions used for this are
517 only an approximation so far
518 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
519 'Sample::LoopSize' which reflected wrong values
520 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
521 measured in sample points instead of byte offset
522 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
523 'Sample::FineTune'
524 - added class attribute 'Sample::LoopSize'
525 - added method GetInstrument(uint index) to class 'File'
526 - added ReadAndLoop() method to class 'Sample' which is an extension to
527 the normal Read() method to honor the sample's looping information
528 while streaming from disk
529 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
530 'eg2_ctrl_t': replaced this huge enumeration by a structure which
531 reflects the MIDI controller number in case of an ordinary control
532 change controller (this saves a huge switch-case block in the
533 application of the library user)
534 - renamed following attributes in class 'DimensionRegion':
535 'AttenuationContol' -> 'AttenuationController',
536 'InvertAttenuationControl' -> 'InvertAttenuationController',
537 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
538 - minor fix in API documentation for method GetVelocityAttenuation() in
539 class 'DimensionRegion'
540
541 * src/RIFF.cpp, src/RIFF.h:
542 - added additional API documentation
543 - minor fix in Chunk::Read() method (only a minor efficiency issue)
544
545 * src/gigdump.cpp:
546 - added printout of samples' looping informations
547
