Thu May 22 12:14:04 2014 UTC (9 years, 10 months ago) by schoenebeck
File size: 22808 byte(s)
* Added fork of libakai (this fork provides Linux support) which
  allows reading AKAI medias. Comes with two command line tools
  'akaidump' and 'akaiextract'. Also added a man page for each
  tool.

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

24 (.KMP and .KSF files)
25
26 * AKAI file format:
27 - Added Linux/POSIX ported version of libakai. Note that libakai is released
28 under LGPL terms while libgig is released under GPL terms. To handle this
29 license difference appropriately the AKAI support part is built as
30 separate DLL (.so file).

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

175 instruments
176 - write support: improved the default values for dimension region
177 parameters
178 - more write support fixes: crossfade parameters were not saved,

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

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

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

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

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

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

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