27
28 Version 3.3.0 (30 Jul 2009)
29
30 * general changes:
31 - fixed compilation with gcc 4.3
32 - fixes for building with Visual C++
33 - minor fix in configure for building DLL on Windows
34
35 * src/gig.cpp, src/gig.h:
36 - added partial support for MIDI rules, only the Controller
37 Triggered rule is supported so far
38 - bugfix: removed another iterator invalidation in DeleteSample
39 - bugfix in Sample::LoadSampleData*(): reset sample read position to
40 sample start before trying to (re)load sample data from file (#82)
41 - bugfix: EG3 depth parameter was not saved correctly

99 - added missing parameter initalizations in sample, region and
100 instrument constructors
101 - clear unused fields when saving samples and regions
102 - fixed write support bugs: v3 dimension limits and chunksize
103 weren't saved, leverage controller of type controlchange
104 couldn't be saved, group name list chunk was placed wrong,
105 dimension region chunks also placed wrong
106 - added initialization of some fixed info strings in file and
107 instrument
108 - write support: files created by libgig will now have the RIFF
109 chunks in correct order

116 - write support: DLSID is now generated on the file and the
117 instruments
118 - write support: improved the default values for dimension region
119 parameters
120 - more write support fixes: crossfade parameters were not saved,
121 v3 dimension limits were not correctly initialized and saved
122 when dimensions were added or deleted, v3 wave pool offsets were
123 not saved correctly
124 - write support: 24 bit samples can now be written
125 - write support: version 3 is now the default for new files
126 - more write support fixes: the 3ewg chunk is now bigger for v3,
127 dimension regions without mapped samples are now allowed, 3gnl
128 list in v3 files now always has 128 entries, several parameters
129 where incorrectly saved due to an operator precedence mistake
130 - DeleteSample now removes all references to the deleted sample
131 - AddDimension now copies all parameters from existing dimension
132 regions and also makes sure that the samplechannel dimension is
133 placed first in the list of dimensions.
134 - added method GetParent() to class 'DimensionRegion', which returns its
135 parent Region
136 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
137 unused areas
138 - added various setter methods to DimensionRegion class which take care
139 of updating lookup tables / caches.

156 - custom velocity splits now works for gig v3 files too
157 - added support for custom splits points for other dimensions than
158 velocity (gig v3 feature)
159 - added "smart midi" and "round robin keyboard" dimensions
160 - added new method File::DeleteGroupOnly() which only deletes the given
161 group but moves all its members to another group, the other method,
162 that is File::DeleteGroup() now removes not just the group, but also
163 all the samples that belong to that group
164 - fixed crash which occured on interfering File::DeleteSample() and
165 File::GetNextSample() calls (due to iterator invalidation)
166 - fixed group names which were not saved
167 - fixed group destructor which did not remove the RIFF chunk associated
168 with the group
169 - added Instrument::MoveRegion method
170 - fixed constructor for Region, which did not initialize correctly
171 when used from Instrument::AddRegion
172 - when saving, override the gig::Regions sample reference simply by
173 the region's first dimension region's sample (avoids an exception
174 when trying to save a new instrument)

176 dimension definition fields
177
178 * src/DLS.cpp, src/DLS.h:

312 (patch by Andreas Persson)
313 - added some file format compatibility checks
314 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

369 SuSE and Fedora)
370 - fixed generation of Doxygen API documentation (now also included in
371 RPM and Debian packages)
372
373 * src/gig.cpp, src/gig.h:
374 - fixed / improved accuracy of all three velocity to volume
375 transformation functions a.k.a. 'nonlinear','linear','special'
376 (patch by Andreas Persson)
377 - denormals are filtered from the velocity to volume tables
378 - bugfix for dimension region switching (wrong handling of the release

409
410 * general changes:
411 - various big endian specific corrections
412 (successfully tested now on PPC)
413 - minor adjustments to avoid compile errors on some systems
414 (using now pow() instead of powl() and --pedantic g++ compiler switch)
415 - libtoolized the library
416 - added man pages for the command line tools
417 (gigextract, gigdump, dlsdump, rifftree)
418
419 * src/gig.cpp, src/gig.h:
420 - fixed bug in decompression algorithm which caused it not to detect
421 the end of a stream
422 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
423 takes the MIDI key velocity value as an argument and returns the
424 appropriate volume factor (0.0 ... 1.0) for the sample to be played
425 back, the velocity curve transformation functions used for this are
426 only an approximation so far
427 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
428 'Sample::LoopSize' which reflected wrong values
429 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
430 measured in sample points instead of byte offset
431 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
432 'Sample::FineTune'
433 - added class attribute 'Sample::LoopSize'
434 - added method GetInstrument(uint index) to class 'File'
435 - added ReadAndLoop() method to class 'Sample' which is an extension to
436 the normal Read() method to honor the sample's looping information
437 while streaming from disk
438 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
439 'eg2_ctrl_t': replaced this huge enumeration by a structure which
440 reflects the MIDI controller number in case of an ordinary control
441 change controller (this saves a huge switch-case block in the
442 application of the library user)
443 - renamed following attributes in class 'DimensionRegion':
444 'AttenuationContol' -> 'AttenuationController',
445 'InvertAttenuationControl' -> 'InvertAttenuationController',
446 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
447 - minor fix in API documentation for method GetVelocityAttenuation() in
448 class 'DimensionRegion'
449
450 * src/RIFF.cpp, src/RIFF.h:
451 - added additional API documentation
452 - minor fix in Chunk::Read() method (only a minor efficiency issue)
453
454 * src/gigdump.cpp:
455 - added printout of samples' looping informations
456
457 Version 0.6.0 (3 Nov 2003)
458
459 * initial release
