118
119 * packaging changes:
120 - added Mac OSX XCode project files (patch by Toshi Nagata)

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

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

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

222 dimension definition fields
223
224 * src/DLS.cpp, src/DLS.h:

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

358 (patch by Andreas Persson)
359 - added some file format compatibility checks
360 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

410
411 * packaging changes:
412 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

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

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