* Akai: Fixed Mac OSX support so that the Akai lib files and tools
  compile without any exotic third party libraries.

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
16 * SoundFont file format:
17 - initial implementation
18 - changed region lookup API to avoid malloc in RT threads

160 instrument constructors
161 - clear unused fields when saving samples and regions
162 - fixed write support bugs: v3 dimension limits and chunksize

177 instruments
178 - write support: improved the default values for dimension region
179 parameters
180 - more write support fixes: crossfade parameters were not saved,
181 v3 dimension limits were not correctly initialized and saved
182 when dimensions were added or deleted, v3 wave pool offsets were
183 not saved correctly
184 - write support: 24 bit samples can now be written

188 list in v3 files now always has 128 entries, several parameters
189 where incorrectly saved due to an operator precedence mistake
190 - DeleteSample now removes all references to the deleted sample
191 - AddDimension now copies all parameters from existing dimension
192 regions and also makes sure that the samplechannel dimension is
193 placed first in the list of dimensions.

195 parent Region
196 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
197 unused areas

217 - added support for custom splits points for other dimensions than
218 velocity (gig v3 feature)
219 - added "smart midi" and "round robin keyboard" dimensions
220 - added new method File::DeleteGroupOnly() which only deletes the given
221 group but moves all its members to another group, the other method,
222 that is File::DeleteGroup() now removes not just the group, but also
223 all the samples that belong to that group
224 - fixed crash which occured on interfering File::DeleteSample() and
225 File::GetNextSample() calls (due to iterator invalidation)

230 - fixed constructor for Region, which did not initialize correctly
231 when used from Instrument::AddRegion
232 - when saving, override the gig::Regions sample reference simply by
233 the region's first dimension region's sample (avoids an exception
234 when trying to save a new instrument)

429 SuSE and Fedora)
430 - fixed generation of Doxygen API documentation (now also included in
431 RPM and Debian packages)
432
433 * src/gig.cpp, src/gig.h:
434 - fixed / improved accuracy of all three velocity to volume
435 transformation functions a.k.a. 'nonlinear','linear','special'
436 (patch by Andreas Persson)
437 - denormals are filtered from the velocity to volume tables

461 - added libgig.spec and libgig.pc package configurations for generating
462 Redhat packages
463 - header files included on installation.
464 - autotools-generated files removed from CVS repository.
465 - added support for generating Debian packages
466 - version of shared library can be set in configure.in
467
468 Version 0.7.0 (3 May 2004)
469
470 * general changes:
471 - various big endian specific corrections
472 (successfully tested now on PPC)
473 - minor adjustments to avoid compile errors on some systems
474 (using now pow() instead of powl() and --pedantic g++ compiler switch)
475 - libtoolized the library
476 - added man pages for the command line tools
477 (gigextract, gigdump, dlsdump, rifftree)
478
479 * src/gig.cpp, src/gig.h:
480 - fixed bug in decompression algorithm which caused it not to detect
481 the end of a stream
482 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
483 takes the MIDI key velocity value as an argument and returns the
484 appropriate volume factor (0.0 ... 1.0) for the sample to be played
485 back, the velocity curve transformation functions used for this are
486 only an approximation so far
487 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
488 'Sample::LoopSize' which reflected wrong values
489 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
490 measured in sample points instead of byte offset
491 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
492 'Sample::FineTune'
493 - added class attribute 'Sample::LoopSize'
494 - added method GetInstrument(uint index) to class 'File'
495 - added ReadAndLoop() method to class 'Sample' which is an extension to
496 the normal Read() method to honor the sample's looping information
497 while streaming from disk
498 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
499 'eg2_ctrl_t': replaced this huge enumeration by a structure which
500 reflects the MIDI controller number in case of an ordinary control
501 change controller (this saves a huge switch-case block in the
502 application of the library user)
503 - renamed following attributes in class 'DimensionRegion':
504 'AttenuationContol' -> 'AttenuationController',
505 'InvertAttenuationControl' -> 'InvertAttenuationController',
506 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
507 - minor fix in API documentation for method GetVelocityAttenuation() in
508 class 'DimensionRegion'
509
510 * src/RIFF.cpp, src/RIFF.h:
511 - added additional API documentation
512 - minor fix in Chunk::Read() method (only a minor efficiency issue)
513
514 * src/gigdump.cpp:
515 - added printout of samples' looping informations
516
517 Version 0.6.0 (3 Nov 2003)
518
519 * initial release
