84
85 Version 3.2.0 (14 Oct 2007)
86
87 * packaging changes:
88 - added Mac OSX XCode project files (patch by Toshi Nagata)
89 - Dev-C++ (win32) project file is automatically updated with

97 - improved handling of fixed length info strings - separate default
98 lengths can be specified for each INFO chunk
99 - added Resource::GenerateDLSID function
100 - write support fix: allow regions without mapped samples
101 - added method SetKeyRange() to the Region class which should be used

108 - fixed segmentation fault in the gig::File destructor sequence which
109 happened when gig::Group informations were accessed before
110 - fixed write support for big-endian systems

112 are saved when the file is written, even if they are empty.
113 - added missing parameter initalizations in sample, region and
114 instrument constructors
115 - clear unused fields when saving samples and regions
116 - fixed write support bugs: v3 dimension limits and chunksize
117 weren't saved, leverage controller of type controlchange
118 couldn't be saved, group name list chunk was placed wrong,
119 dimension region chunks also placed wrong
120 - added initialization of some fixed info strings in file and
121 instrument
122 - write support: files created by libgig will now have the RIFF
123 chunks in correct order
124 - write support: two previously unknown fields in dimension
125 definition are now saved
126 - added constants for gig file versions

128 updated when a file is saved (3crc contains sample checksums,
129 einf contains file statistics)
130 - write support: DLSID is now generated on the file and the
131 instruments
132 - write support: improved the default values for dimension region
133 parameters
134 - more write support fixes: crossfade parameters were not saved,
135 v3 dimension limits were not correctly initialized and saved
136 when dimensions were added or deleted, v3 wave pool offsets were
137 not saved correctly
138 - write support: 24 bit samples can now be written
139 - write support: version 3 is now the default for new files
140 - more write support fixes: the 3ewg chunk is now bigger for v3,
141 dimension regions without mapped samples are now allowed, 3gnl
142 list in v3 files now always has 128 entries, several parameters
143 where incorrectly saved due to an operator precedence mistake
144 - DeleteSample now removes all references to the deleted sample
145 - AddDimension now copies all parameters from existing dimension
146 regions and also makes sure that the samplechannel dimension is
147 placed first in the list of dimensions.
148 - added method GetParent() to class 'DimensionRegion', which returns its
149 parent Region
150 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
151 unused areas
152 - added various setter methods to DimensionRegion class which take care
153 of updating lookup tables / caches.
154

156 - added File::SetByteOrder method
157 - Windows fix: saving a new file didn't work

161
162 Version 3.1.1 (24 Mar 2007)
163

170 - custom velocity splits now works for gig v3 files too
171 - added support for custom splits points for other dimensions than
172 velocity (gig v3 feature)
173 - added "smart midi" and "round robin keyboard" dimensions
174 - added new method File::DeleteGroupOnly() which only deletes the given
175 group but moves all its members to another group, the other method,
176 that is File::DeleteGroup() now removes not just the group, but also
177 all the samples that belong to that group
178 - fixed crash which occured on interfering File::DeleteSample() and
179 File::GetNextSample() calls (due to iterator invalidation)
180 - fixed group names which were not saved
181 - fixed group destructor which did not remove the RIFF chunk associated
182 with the group
183 - added Instrument::MoveRegion method
184 - fixed constructor for Region, which did not initialize correctly
185 when used from Instrument::AddRegion
186 - when saving, override the gig::Regions sample reference simply by
187 the region's first dimension region's sample (avoids an exception
188 when trying to save a new instrument)
189 - fixed AddDimension() method which did not fill out all mandatory
190 dimension definition fields
191
192 * src/DLS.cpp, src/DLS.h:
193 - added Instrument::MoveRegion method

195 causing an exception when trying to save a new instrument
196
197 * src/RIFF.cpp, src/RIFF.h:

199 resized chunks, leading to a "zero size chunk" exception when
200 File::Save() was called
201 - added List::MoveSubChunk method
202

264 - added write support
265 - Chunk::LoadChunkData() can now be called again to resize the buffer
266 after a Chunk::Resize() and before the File::Save() call to allow

325 articulation informations are ignored at the moment
326 (patch by Andreas Persson)
327 - added some file format compatibility checks
328 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
329 never used, because the necessary check was made before

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

378
379 * packaging changes:
380 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
381 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
382 - fixed man pages automake install rule (which didn't work on Mandrake,
383 SuSE and Fedora)
384 - fixed generation of Doxygen API documentation (now also included in
385 RPM and Debian packages)
386
387 * src/gig.cpp, src/gig.h:
388 - fixed / improved accuracy of all three velocity to volume
389 transformation functions a.k.a. 'nonlinear','linear','special'
390 (patch by Andreas Persson)
391 - denormals are filtered from the velocity to volume tables
392 - bugfix for dimension region switching (wrong handling of the release
393 trigger dimension, no bit range check for dimensions of split type

397 - added class attribute 'Layers' to class 'gig::Region'
398 - symbol prototyping of gig::Region (fixes build failure with qsampler)
399

415 - added libgig.spec and libgig.pc package configurations for generating
416 Redhat packages
417 - header files included on installation.
418 - autotools-generated files removed from CVS repository.
419 - added support for generating Debian packages
420 - version of shared library can be set in configure.in
421
422 Version 0.7.0 (3 May 2004)
423
424 * general changes:
425 - various big endian specific corrections
426 (successfully tested now on PPC)
427 - minor adjustments to avoid compile errors on some systems
428 (using now pow() instead of powl() and --pedantic g++ compiler switch)
429 - libtoolized the library
430 - added man pages for the command line tools
431 (gigextract, gigdump, dlsdump, rifftree)
432
433 * src/gig.cpp, src/gig.h:
434 - fixed bug in decompression algorithm which caused it not to detect
435 the end of a stream
436 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
437 takes the MIDI key velocity value as an argument and returns the
438 appropriate volume factor (0.0 ... 1.0) for the sample to be played
439 back, the velocity curve transformation functions used for this are
440 only an approximation so far
441 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
442 'Sample::LoopSize' which reflected wrong values
443 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
444 measured in sample points instead of byte offset
445 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
446 'Sample::FineTune'
447 - added class attribute 'Sample::LoopSize'
448 - added method GetInstrument(uint index) to class 'File'
449 - added ReadAndLoop() method to class 'Sample' which is an extension to
450 the normal Read() method to honor the sample's looping information
451 while streaming from disk
452 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
453 'eg2_ctrl_t': replaced this huge enumeration by a structure which
454 reflects the MIDI controller number in case of an ordinary control
455 change controller (this saves a huge switch-case block in the
456 application of the library user)
457 - renamed following attributes in class 'DimensionRegion':
458 'AttenuationContol' -> 'AttenuationController',
459 'InvertAttenuationControl' -> 'InvertAttenuationController',
460 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
461 - minor fix in API documentation for method GetVelocityAttenuation() in
462 class 'DimensionRegion'
463
464 * src/RIFF.cpp, src/RIFF.h:
465 - added additional API documentation
466 - minor fix in Chunk::Read() method (only a minor efficiency issue)
467
468 * src/gigdump.cpp:
469 - added printout of samples' looping informations
470
471 Version 0.6.0 (3 Nov 2003)
472
473 * initial release
