20
21 * SoundFont file format:
22 - initial implementation
23 - changed region lookup API to avoid malloc in RT threads

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

45 saved

52 - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
53 controller types (only works with LinuxSampler & gigedit, will not

65
66 * src/DLS.cpp, src/DLS.h:
67 - added new method File::GetFileName()
68 - fixed minor "memory leak on exception" bug found with cppcheck

87 - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
88 allows to move a subchunk within the current List, whereas the new 2nd
89 one allows to move the subchunk from the current list to another list
90
91 * src/gigextract.cpp:
92 - export sample loop, unity note and fine tune with libsndfile
93
94 * src/riftree.cpp:

116 - bugfix: saving to the same file after the file size had been
117 increased made the file corrupt (#82)
118 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
119 is not written physically yet (#82)
120 - bugfix: saving to the same file after the file size had been
121 decreased sometimes also made the file corrupt!
122 - bugfix: undefined behavior (e.g. endless loop) when opening zero
123 length files, now throws a RIFF::Exception instead (fixes bug #121)
124 - bugfix: destructor for base class RIFF::Chunk accessed members
125 of derived class RIFF::File, which is bad, and caused crashes
126 when using Visual C++
127 - bugfix: files that contain zero length RIFF lists were not read
128 correctly (fixes #127) (bug was introduced 2009-03-13)

169 - added missing parameter initalizations in sample, region and
170 instrument constructors
171 - clear unused fields when saving samples and regions
172 - fixed write support bugs: v3 dimension limits and chunksize
173 weren't saved, leverage controller of type controlchange
174 couldn't be saved, group name list chunk was placed wrong,
175 dimension region chunks also placed wrong

186 - write support: DLSID is now generated on the file and the
187 instruments
188 - write support: improved the default values for dimension region
189 parameters
190 - more write support fixes: crossfade parameters were not saved,
191 v3 dimension limits were not correctly initialized and saved
192 when dimensions were added or deleted, v3 wave pool offsets were
193 not saved correctly
194 - write support: 24 bit samples can now be written
195 - write support: version 3 is now the default for new files
196 - more write support fixes: the 3ewg chunk is now bigger for v3,
197 dimension regions without mapped samples are now allowed, 3gnl
198 list in v3 files now always has 128 entries, several parameters
199 where incorrectly saved due to an operator precedence mistake
200 - DeleteSample now removes all references to the deleted sample
201 - AddDimension now copies all parameters from existing dimension
202 regions and also makes sure that the samplechannel dimension is
203 placed first in the list of dimensions.
204 - added method GetParent() to class 'DimensionRegion', which returns its
205 parent Region
206 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
207 unused areas
208 - added various setter methods to DimensionRegion class which take care
209 of updating lookup tables / caches.

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

246 dimension definition fields
247
248 * src/DLS.cpp, src/DLS.h:

320 - added write support
321 - Chunk::LoadChunkData() can now be called again to resize the buffer
322 after a Chunk::Resize() and before the File::Save() call to allow
323 placing the new data in the chunk's write buffer and perform the
324 resize and write operations in one rush
325

382 (patch by Andreas Persson)
383 - added some file format compatibility checks
384 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
385 never used, because the necessary check was made before

387 - fixed crossfade points order (structure for big endian and little
388 endian systems was interchanged)

439 SuSE and Fedora)
440 - fixed generation of Doxygen API documentation (now also included in
441 RPM and Debian packages)
442
443 * src/gig.cpp, src/gig.h:
444 - fixed / improved accuracy of all three velocity to volume
445 transformation functions a.k.a. 'nonlinear','linear','special'
446 (patch by Andreas Persson)
447 - denormals are filtered from the velocity to volume tables
448 - bugfix for dimension region switching (wrong handling of the release
449 trigger dimension, no bit range check for dimensions of split type

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