12
13 * src/gig.cpp, src/gig.h:
14 - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
15 applications to retrieve very superficial informations like amount of
16 instruments and their names in a very fast way
17
18 Version 3.2.0 (14 Oct 2007)
19
20 * packaging changes:
21 - added Mac OSX XCode project files (patch by Toshi Nagata)
22 - Dev-C++ (win32) project file is automatically updated with

28 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
29 - fixed write support for big-endian systems
30 - improved handling of fixed length info strings - separate default
31 lengths can be specified for each INFO chunk
32 - added Resource::GenerateDLSID function
33 - write support fix: allow regions without mapped samples
34 - added method SetKeyRange() to the Region class which should be used
35 instead of setting the KeyRange member variable directly

41 - fixed segmentation fault in the gig::File destructor sequence which
42 happened when gig::Group informations were accessed before
43 - fixed write support for big-endian systems
44 - defined lengths of a fixed set of info strings. These strings
45 are saved when the file is written, even if they are empty.
46 - added missing parameter initalizations in sample, region and
47 instrument constructors
48 - clear unused fields when saving samples and regions
49 - fixed write support bugs: v3 dimension limits and chunksize
50 weren't saved, leverage controller of type controlchange
51 couldn't be saved, group name list chunk was placed wrong,
52 dimension region chunks also placed wrong
53 - added initialization of some fixed info strings in file and
54 instrument
55 - write support: files created by libgig will now have the RIFF
56 chunks in correct order
57 - write support: two previously unknown fields in dimension
58 definition are now saved
59 - added constants for gig file versions

61 updated when a file is saved (3crc contains sample checksums,
62 einf contains file statistics)
63 - write support: DLSID is now generated on the file and the
64 instruments
65 - write support: improved the default values for dimension region
66 parameters
67 - more write support fixes: crossfade parameters were not saved,
68 v3 dimension limits were not correctly initialized and saved
69 when dimensions were added or deleted, v3 wave pool offsets were
70 not saved correctly
71 - write support: 24 bit samples can now be written
72 - write support: version 3 is now the default for new files
73 - more write support fixes: the 3ewg chunk is now bigger for v3,
74 dimension regions without mapped samples are now allowed, 3gnl
75 list in v3 files now always has 128 entries, several parameters
76 where incorrectly saved due to an operator precedence mistake
77 - DeleteSample now removes all references to the deleted sample
78 - AddDimension now copies all parameters from existing dimension
79 regions and also makes sure that the samplechannel dimension is
80 placed first in the list of dimensions.
81 - added method GetParent() to class 'DimensionRegion', which returns its
82 parent Region
83 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
84 unused areas
85 - added various setter methods to DimensionRegion class which take care
86 of updating lookup tables / caches.
87
88 * src/RIFF.cpp, src/RIFF.h:
89 - added File::SetByteOrder method
90 - Windows fix: saving a new file didn't work

103 - custom velocity splits now works for gig v3 files too
104 - added support for custom splits points for other dimensions than
105 velocity (gig v3 feature)
106 - added "smart midi" and "round robin keyboard" dimensions
107 - added new method File::DeleteGroupOnly() which only deletes the given
108 group but moves all its members to another group, the other method,
109 that is File::DeleteGroup() now removes not just the group, but also
110 all the samples that belong to that group
111 - fixed crash which occured on interfering File::DeleteSample() and
112 File::GetNextSample() calls (due to iterator invalidation)
113 - fixed group names which were not saved
114 - fixed group destructor which did not remove the RIFF chunk associated
115 with the group
116 - added Instrument::MoveRegion method
117 - fixed constructor for Region, which did not initialize correctly
118 when used from Instrument::AddRegion
119 - when saving, override the gig::Regions sample reference simply by
120 the region's first dimension region's sample (avoids an exception
121 when trying to save a new instrument)
122 - fixed AddDimension() method which did not fill out all mandatory
123 dimension definition fields
124
125 * src/DLS.cpp, src/DLS.h:
126 - added Instrument::MoveRegion method

128 causing an exception when trying to save a new instrument
129
130 * src/RIFF.cpp, src/RIFF.h:

132 resized chunks, leading to a "zero size chunk" exception when
133 File::Save() was called
134 - added List::MoveSubChunk method
135

259 (patch by Andreas Persson)
260 - added some file format compatibility checks
261 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

311
312 * packaging changes:
313 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
314 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
315 - fixed man pages automake install rule (which didn't work on Mandrake,
316 SuSE and Fedora)
317 - fixed generation of Doxygen API documentation (now also included in
318 RPM and Debian packages)
319
320 * src/gig.cpp, src/gig.h:
321 - fixed / improved accuracy of all three velocity to volume
322 transformation functions a.k.a. 'nonlinear','linear','special'
323 (patch by Andreas Persson)
324 - denormals are filtered from the velocity to volume tables
325 - bugfix for dimension region switching (wrong handling of the release
326 trigger dimension, no bit range check for dimensions of split type
327 'split_type_bit')

329 signed 7 bit to signed 8 bit)
330 - added class attribute 'Layers' to class 'gig::Region'
331 - symbol prototyping of gig::Region (fixes build failure with qsampler)
332

346
347 * packaging changes:
348 - added libgig.spec and libgig.pc package configurations for generating
349 Redhat packages
350 - header files included on installation.
351 - autotools-generated files removed from CVS repository.
352 - added support for generating Debian packages
353 - version of shared library can be set in configure.in
354
355 Version 0.7.0 (3 May 2004)
356
357 * general changes:
358 - various big endian specific corrections
359 (successfully tested now on PPC)
360 - minor adjustments to avoid compile errors on some systems
361 (using now pow() instead of powl() and --pedantic g++ compiler switch)
362 - libtoolized the library
363 - added man pages for the command line tools
364 (gigextract, gigdump, dlsdump, rifftree)
365
366 * src/gig.cpp, src/gig.h:
367 - fixed bug in decompression algorithm which caused it not to detect
368 the end of a stream
369 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
370 takes the MIDI key velocity value as an argument and returns the
371 appropriate volume factor (0.0 ... 1.0) for the sample to be played
372 back, the velocity curve transformation functions used for this are
373 only an approximation so far
374 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
375 'Sample::LoopSize' which reflected wrong values
376 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
377 measured in sample points instead of byte offset
378 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
379 'Sample::FineTune'
380 - added class attribute 'Sample::LoopSize'
381 - added method GetInstrument(uint index) to class 'File'
382 - added ReadAndLoop() method to class 'Sample' which is an extension to
383 the normal Read() method to honor the sample's looping information
384 while streaming from disk
385 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
386 'eg2_ctrl_t': replaced this huge enumeration by a structure which
387 reflects the MIDI controller number in case of an ordinary control
388 change controller (this saves a huge switch-case block in the
389 application of the library user)
390 - renamed following attributes in class 'DimensionRegion':
391 'AttenuationContol' -> 'AttenuationController',
392 'InvertAttenuationControl' -> 'InvertAttenuationController',
393 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
394 - minor fix in API documentation for method GetVelocityAttenuation() in
395 class 'DimensionRegion'
396
397 * src/RIFF.cpp, src/RIFF.h:
398 - added additional API documentation
399 - minor fix in Chunk::Read() method (only a minor efficiency issue)
400
401 * src/gigdump.cpp:
402 - added printout of samples' looping informations
403
404 Version 0.6.0 (3 Nov 2003)
405
406 * initial release
