94
95 Version 3.2.0 (14 Oct 2007)
96
97 * packaging changes:
98 - added Mac OSX XCode project files (patch by Toshi Nagata)
99 - Dev-C++ (win32) project file is automatically updated with

108 lengths can be specified for each INFO chunk
109 - added Resource::GenerateDLSID function
110 - write support fix: allow regions without mapped samples
111 - added method SetKeyRange() to the Region class which should be used

122 are saved when the file is written, even if they are empty.
123 - added missing parameter initalizations in sample, region and
124 instrument constructors
125 - clear unused fields when saving samples and regions
126 - fixed write support bugs: v3 dimension limits and chunksize
127 weren't saved, leverage controller of type controlchange
128 couldn't be saved, group name list chunk was placed wrong,
129 dimension region chunks also placed wrong
130 - added initialization of some fixed info strings in file and
131 instrument
132 - write support: files created by libgig will now have the RIFF
133 chunks in correct order

141 instruments
142 - write support: improved the default values for dimension region
143 parameters
144 - more write support fixes: crossfade parameters were not saved,
145 v3 dimension limits were not correctly initialized and saved
146 when dimensions were added or deleted, v3 wave pool offsets were
147 not saved correctly
148 - write support: 24 bit samples can now be written
149 - write support: version 3 is now the default for new files
150 - more write support fixes: the 3ewg chunk is now bigger for v3,
151 dimension regions without mapped samples are now allowed, 3gnl
152 list in v3 files now always has 128 entries, several parameters
153 where incorrectly saved due to an operator precedence mistake
154 - DeleteSample now removes all references to the deleted sample
155 - AddDimension now copies all parameters from existing dimension
156 regions and also makes sure that the samplechannel dimension is
157 placed first in the list of dimensions.
158 - added method GetParent() to class 'DimensionRegion', which returns its
159 parent Region
160 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
161 unused areas
162 - added various setter methods to DimensionRegion class which take care
163 of updating lookup tables / caches.
164

180 - custom velocity splits now works for gig v3 files too
181 - added support for custom splits points for other dimensions than
182 velocity (gig v3 feature)
183 - added "smart midi" and "round robin keyboard" dimensions
184 - added new method File::DeleteGroupOnly() which only deletes the given
185 group but moves all its members to another group, the other method,
186 that is File::DeleteGroup() now removes not just the group, but also
187 all the samples that belong to that group
188 - fixed crash which occured on interfering File::DeleteSample() and
189 File::GetNextSample() calls (due to iterator invalidation)
190 - fixed group names which were not saved
191 - fixed group destructor which did not remove the RIFF chunk associated
192 with the group
193 - added Instrument::MoveRegion method
194 - fixed constructor for Region, which did not initialize correctly
195 when used from Instrument::AddRegion
196 - when saving, override the gig::Regions sample reference simply by
197 the region's first dimension region's sample (avoids an exception
198 when trying to save a new instrument)
199 - fixed AddDimension() method which did not fill out all mandatory
200 dimension definition fields
201
202 * src/DLS.cpp, src/DLS.h:
203 - added Instrument::MoveRegion method

206
207 * src/RIFF.cpp, src/RIFF.h:

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

335 articulation informations are ignored at the moment
336 (patch by Andreas Persson)
337 - added some file format compatibility checks
338 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
339 never used, because the necessary check was made before

388
389 * packaging changes:
390 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
391 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
392 - fixed man pages automake install rule (which didn't work on Mandrake,
393 SuSE and Fedora)
394 - fixed generation of Doxygen API documentation (now also included in
395 RPM and Debian packages)
396
397 * src/gig.cpp, src/gig.h:
398 - fixed / improved accuracy of all three velocity to volume
399 transformation functions a.k.a. 'nonlinear','linear','special'
400 (patch by Andreas Persson)
401 - denormals are filtered from the velocity to volume tables
402 - bugfix for dimension region switching (wrong handling of the release
403 trigger dimension, no bit range check for dimensions of split type

405 - fixed panorama value in DimensionRegion (invalid conversion from
406 signed 7 bit to signed 8 bit)
407 - added class attribute 'Layers' to class 'gig::Region'
408 - symbol prototyping of gig::Region (fixes build failure with qsampler)
409
410 * src/gigextract.cpp:

422 Version 0.7.1 (2 Jul 2004)
423

425 - added libgig.spec and libgig.pc package configurations for generating
426 Redhat packages
427 - header files included on installation.
428 - autotools-generated files removed from CVS repository.
429 - added support for generating Debian packages
430 - version of shared library can be set in configure.in
431
432 Version 0.7.0 (3 May 2004)
433
434 * general changes:
435 - various big endian specific corrections
436 (successfully tested now on PPC)
437 - minor adjustments to avoid compile errors on some systems
438 (using now pow() instead of powl() and --pedantic g++ compiler switch)
439 - libtoolized the library
440 - added man pages for the command line tools
441 (gigextract, gigdump, dlsdump, rifftree)
442
443 * src/gig.cpp, src/gig.h:
444 - fixed bug in decompression algorithm which caused it not to detect
445 the end of a stream
446 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
447 takes the MIDI key velocity value as an argument and returns the
448 appropriate volume factor (0.0 ... 1.0) for the sample to be played
449 back, the velocity curve transformation functions used for this are
450 only an approximation so far
451 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
452 'Sample::LoopSize' which reflected wrong values
453 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
454 measured in sample points instead of byte offset
455 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
456 'Sample::FineTune'
457 - added class attribute 'Sample::LoopSize'
458 - added method GetInstrument(uint index) to class 'File'
459 - added ReadAndLoop() method to class 'Sample' which is an extension to
460 the normal Read() method to honor the sample's looping information
461 while streaming from disk
462 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
463 'eg2_ctrl_t': replaced this huge enumeration by a structure which
464 reflects the MIDI controller number in case of an ordinary control
465 change controller (this saves a huge switch-case block in the
466 application of the library user)
467 - renamed following attributes in class 'DimensionRegion':
468 'AttenuationContol' -> 'AttenuationController',
469 'InvertAttenuationControl' -> 'InvertAttenuationController',
470 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
471 - minor fix in API documentation for method GetVelocityAttenuation() in
472 class 'DimensionRegion'
473
474 * src/RIFF.cpp, src/RIFF.h:
475 - added additional API documentation
476 - minor fix in Chunk::Read() method (only a minor efficiency issue)
477
478 * src/gigdump.cpp:
479 - added printout of samples' looping informations
480
481 Version 0.6.0 (3 Nov 2003)
482
483 * initial release
