25
26 Version 3.3.0 (30 Jul 2009)
27
28 * general changes:
29 - fixed compilation with gcc 4.3
30 - fixes for building with Visual C++
31 - minor fix in configure for building DLL on Windows
32
33 * src/gig.cpp, src/gig.h:
34 - added partial support for MIDI rules, only the Controller
35 Triggered rule is supported so far
36 - bugfix: removed another iterator invalidation in DeleteSample
37 - bugfix in Sample::LoadSampleData*(): reset sample read position to
38 sample start before trying to (re)load sample data from file (#82)
39 - bugfix: EG3 depth parameter was not saved correctly

53 of derived class RIFF::File, which is bad, and caused crashes
54 when using Visual C++
55 - bugfix: files that contain zero length RIFF lists were not read
56 correctly (fixes #127) (bug was introduced 2009-03-13)

66 applications to retrieve very superficial informations like amount of
67 instruments and their names in a very fast way
68
69 Version 3.2.0 (14 Oct 2007)
70
71 * packaging changes:
72 - added Mac OSX XCode project files (patch by Toshi Nagata)

81 - improved handling of fixed length info strings - separate default
82 lengths can be specified for each INFO chunk
83 - added Resource::GenerateDLSID function

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

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

155 - added support for custom splits points for other dimensions than
156 velocity (gig v3 feature)
157 - added "smart midi" and "round robin keyboard" dimensions
158 - added new method File::DeleteGroupOnly() which only deletes the given
159 group but moves all its members to another group, the other method,
160 that is File::DeleteGroup() now removes not just the group, but also
161 all the samples that belong to that group
162 - fixed crash which occured on interfering File::DeleteSample() and
163 File::GetNextSample() calls (due to iterator invalidation)
164 - fixed group names which were not saved

166 with the group
167 - added Instrument::MoveRegion method
168 - fixed constructor for Region, which did not initialize correctly
169 when used from Instrument::AddRegion
170 - when saving, override the gig::Regions sample reference simply by
171 the region's first dimension region's sample (avoids an exception
172 when trying to save a new instrument)

174 dimension definition fields
175
176 * src/DLS.cpp, src/DLS.h:

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

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

399 - added libgig.spec and libgig.pc package configurations for generating
400 Redhat packages
401 - header files included on installation.
402 - autotools-generated files removed from CVS repository.
403 - added support for generating Debian packages
404 - version of shared library can be set in configure.in
405
406 Version 0.7.0 (3 May 2004)
407
408 * general changes:
409 - various big endian specific corrections
410 (successfully tested now on PPC)
411 - minor adjustments to avoid compile errors on some systems
412 (using now pow() instead of powl() and --pedantic g++ compiler switch)
413 - libtoolized the library
414 - added man pages for the command line tools
415 (gigextract, gigdump, dlsdump, rifftree)
416
417 * src/gig.cpp, src/gig.h:
418 - fixed bug in decompression algorithm which caused it not to detect
419 the end of a stream
420 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
421 takes the MIDI key velocity value as an argument and returns the
422 appropriate volume factor (0.0 ... 1.0) for the sample to be played
423 back, the velocity curve transformation functions used for this are
424 only an approximation so far
425 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
426 'Sample::LoopSize' which reflected wrong values
427 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
428 measured in sample points instead of byte offset
429 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
430 'Sample::FineTune'
431 - added class attribute 'Sample::LoopSize'
432 - added method GetInstrument(uint index) to class 'File'
433 - added ReadAndLoop() method to class 'Sample' which is an extension to
434 the normal Read() method to honor the sample's looping information
435 while streaming from disk
436 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
437 'eg2_ctrl_t': replaced this huge enumeration by a structure which
438 reflects the MIDI controller number in case of an ordinary control
439 change controller (this saves a huge switch-case block in the
440 application of the library user)
441 - renamed following attributes in class 'DimensionRegion':
442 'AttenuationContol' -> 'AttenuationController',
443 'InvertAttenuationControl' -> 'InvertAttenuationController',
444 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
445 - minor fix in API documentation for method GetVelocityAttenuation() in
446 class 'DimensionRegion'
447
448 * src/RIFF.cpp, src/RIFF.h:
449 - added additional API documentation
450 - minor fix in Chunk::Read() method (only a minor efficiency issue)
451
452 * src/gigdump.cpp:
453 - added printout of samples' looping informations
454
455 Version 0.6.0 (3 Nov 2003)
456
457 * initial release
