146 are saved when the file is written, even if they are empty.
147 - added missing parameter initalizations in sample, region and
148 instrument constructors
149 - clear unused fields when saving samples and regions
150 - fixed write support bugs: v3 dimension limits and chunksize
151 weren't saved, leverage controller of type controlchange
152 couldn't be saved, group name list chunk was placed wrong,
153 dimension region chunks also placed wrong
154 - added initialization of some fixed info strings in file and
155 instrument
156 - write support: files created by libgig will now have the RIFF
157 chunks in correct order

164 - write support: DLSID is now generated on the file and the
165 instruments
166 - write support: improved the default values for dimension region
167 parameters
168 - more write support fixes: crossfade parameters were not saved,
169 v3 dimension limits were not correctly initialized and saved
170 when dimensions were added or deleted, v3 wave pool offsets were
171 not saved correctly
172 - write support: 24 bit samples can now be written
173 - write support: version 3 is now the default for new files
174 - more write support fixes: the 3ewg chunk is now bigger for v3,
175 dimension regions without mapped samples are now allowed, 3gnl
176 list in v3 files now always has 128 entries, several parameters
177 where incorrectly saved due to an operator precedence mistake
178 - DeleteSample now removes all references to the deleted sample
179 - AddDimension now copies all parameters from existing dimension
180 regions and also makes sure that the samplechannel dimension is
181 placed first in the list of dimensions.
182 - added method GetParent() to class 'DimensionRegion', which returns its
183 parent Region
184 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
185 unused areas
186 - added various setter methods to DimensionRegion class which take care
187 of updating lookup tables / caches.

204 - custom velocity splits now works for gig v3 files too
205 - added support for custom splits points for other dimensions than
206 velocity (gig v3 feature)
207 - added "smart midi" and "round robin keyboard" dimensions
208 - added new method File::DeleteGroupOnly() which only deletes the given
209 group but moves all its members to another group, the other method,
210 that is File::DeleteGroup() now removes not just the group, but also
211 all the samples that belong to that group
212 - fixed crash which occured on interfering File::DeleteSample() and
213 File::GetNextSample() calls (due to iterator invalidation)
214 - fixed group names which were not saved
215 - fixed group destructor which did not remove the RIFF chunk associated
216 with the group
217 - added Instrument::MoveRegion method
218 - fixed constructor for Region, which did not initialize correctly
219 when used from Instrument::AddRegion
220 - when saving, override the gig::Regions sample reference simply by
221 the region's first dimension region's sample (avoids an exception
222 when trying to save a new instrument)

224 dimension definition fields
225
226 * src/DLS.cpp, src/DLS.h:

230
231 * src/RIFF.cpp, src/RIFF.h:

298 - added write support
299 - Chunk::LoadChunkData() can now be called again to resize the buffer
300 after a Chunk::Resize() and before the File::Save() call to allow
301 placing the new data in the chunk's write buffer and perform the
302 resize and write operations in one rush
303

359 articulation informations are ignored at the moment
360 (patch by Andreas Persson)
361 - added some file format compatibility checks
362 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

412
413 * packaging changes:
414 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

416 - fixed man pages automake install rule (which didn't work on Mandrake,
417 SuSE and Fedora)
418 - fixed generation of Doxygen API documentation (now also included in
419 RPM and Debian packages)
420
421 * src/gig.cpp, src/gig.h:
422 - fixed / improved accuracy of all three velocity to volume
423 transformation functions a.k.a. 'nonlinear','linear','special'
424 (patch by Andreas Persson)
425 - denormals are filtered from the velocity to volume tables
426 - bugfix for dimension region switching (wrong handling of the release
427 trigger dimension, no bit range check for dimensions of split type

449 - added libgig.spec and libgig.pc package configurations for generating
450 Redhat packages
451 - header files included on installation.
452 - autotools-generated files removed from CVS repository.
453 - added support for generating Debian packages
454 - version of shared library can be set in configure.in
455
456 Version 0.7.0 (3 May 2004)
457
458 * general changes:
459 - various big endian specific corrections
460 (successfully tested now on PPC)
461 - minor adjustments to avoid compile errors on some systems
462 (using now pow() instead of powl() and --pedantic g++ compiler switch)
463 - libtoolized the library
464 - added man pages for the command line tools
465 (gigextract, gigdump, dlsdump, rifftree)
466
467 * src/gig.cpp, src/gig.h:
468 - fixed bug in decompression algorithm which caused it not to detect
469 the end of a stream
470 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
471 takes the MIDI key velocity value as an argument and returns the
472 appropriate volume factor (0.0 ... 1.0) for the sample to be played
473 back, the velocity curve transformation functions used for this are
474 only an approximation so far
475 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
476 'Sample::LoopSize' which reflected wrong values
477 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
478 measured in sample points instead of byte offset
479 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
480 'Sample::FineTune'
481 - added class attribute 'Sample::LoopSize'
482 - added method GetInstrument(uint index) to class 'File'
483 - added ReadAndLoop() method to class 'Sample' which is an extension to
484 the normal Read() method to honor the sample's looping information
485 while streaming from disk
486 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
487 'eg2_ctrl_t': replaced this huge enumeration by a structure which
488 reflects the MIDI controller number in case of an ordinary control
489 change controller (this saves a huge switch-case block in the
490 application of the library user)
491 - renamed following attributes in class 'DimensionRegion':
492 'AttenuationContol' -> 'AttenuationController',
493 'InvertAttenuationControl' -> 'InvertAttenuationController',
494 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
495 - minor fix in API documentation for method GetVelocityAttenuation() in
496 class 'DimensionRegion'
497
498 * src/RIFF.cpp, src/RIFF.h:
499 - added additional API documentation
500 - minor fix in Chunk::Read() method (only a minor efficiency issue)
501
502 * src/gigdump.cpp:
503 - added printout of samples' looping informations
504
505 Version 0.6.0 (3 Nov 2003)
506
507 * initial release
