  gig file.
* DLS: Added support for custom progress notification while saving to
  DLS file.
* RIFF: Added support for custom progress notification while saving to
  RIFF file.
* Bumped version (3.3.0.svn22).

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
21 * SoundFont file format:
22 - initial implementation
23 - changed region lookup API to avoid malloc in RT threads
24 - fixed GetEG1Sustain which didn't return correct value
25 - bugfix: GetPan always returned -1, 0 or 1
26
27 * KORG file format:
28 - initial support for sample based instruments in KORG's file format
29 (.KMP and .KSF files)
30
31 * AKAI file format:
32 - Added Linux/POSIX ported version of libakai. Note that libakai is released
33 under LGPL terms while libgig is released under GPL terms. To handle this
34 license difference appropriately the AKAI support part is built as
35 separate DLL (.so file).
36 - Fixed Mac OSX support so that the Akai lib files and tools compile without
37 any exotic third party libraries.
38 - Fixed various compilation errors for Windows.
39 - POSIX fix: open() requires third (mode) argument if used with O_CREAT
40 (fixes #219).

92 - added new method Chunk::GetFile()
93 - added new method Chunk::GetLayout()
94 - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
95 allows to move a subchunk within the current List, whereas the new 2nd

125 * src/RIFF.cpp, src/RIFF.h:
126 - bugfix: saving to the same file after the file size had been
127 increased made the file corrupt (#82)
128 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
129 is not written physically yet (#82)

180 instrument constructors
181 - clear unused fields when saving samples and regions
182 - fixed write support bugs: v3 dimension limits and chunksize
183 weren't saved, leverage controller of type controlchange

197 instruments
198 - write support: improved the default values for dimension region
199 parameters
200 - more write support fixes: crossfade parameters were not saved,
201 v3 dimension limits were not correctly initialized and saved
202 when dimensions were added or deleted, v3 wave pool offsets were
203 not saved correctly
204 - write support: 24 bit samples can now be written

206 - more write support fixes: the 3ewg chunk is now bigger for v3,
207 dimension regions without mapped samples are now allowed, 3gnl
208 list in v3 files now always has 128 entries, several parameters
209 where incorrectly saved due to an operator precedence mistake
210 - DeleteSample now removes all references to the deleted sample
211 - AddDimension now copies all parameters from existing dimension
212 regions and also makes sure that the samplechannel dimension is
213 placed first in the list of dimensions.
214 - added method GetParent() to class 'DimensionRegion', which returns its
215 parent Region
216 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
217 unused areas
218 - added various setter methods to DimensionRegion class which take care
219 of updating lookup tables / caches.

237 - added support for custom splits points for other dimensions than
238 velocity (gig v3 feature)
239 - added "smart midi" and "round robin keyboard" dimensions
240 - added new method File::DeleteGroupOnly() which only deletes the given
241 group but moves all its members to another group, the other method,
242 that is File::DeleteGroup() now removes not just the group, but also
243 all the samples that belong to that group
244 - fixed crash which occured on interfering File::DeleteSample() and
245 File::GetNextSample() calls (due to iterator invalidation)
246 - fixed group names which were not saved
247 - fixed group destructor which did not remove the RIFF chunk associated
248 with the group
249 - added Instrument::MoveRegion method
250 - fixed constructor for Region, which did not initialize correctly
251 when used from Instrument::AddRegion
252 - when saving, override the gig::Regions sample reference simply by
253 the region's first dimension region's sample (avoids an exception
254 when trying to save a new instrument)

256 dimension definition fields
257
258 * src/DLS.cpp, src/DLS.h:

449 SuSE and Fedora)
450 - fixed generation of Doxygen API documentation (now also included in
451 RPM and Debian packages)
452
453 * src/gig.cpp, src/gig.h:
454 - fixed / improved accuracy of all three velocity to volume
455 transformation functions a.k.a. 'nonlinear','linear','special'
456 (patch by Andreas Persson)
457 - denormals are filtered from the velocity to volume tables

481 - added libgig.spec and libgig.pc package configurations for generating
482 Redhat packages
483 - header files included on installation.
484 - autotools-generated files removed from CVS repository.

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