* src/gig.h, src/gig.cpp:
  - added method GetParent() to class 'DimensionRegion', which returns its
    parent Region

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - added Mac OSX XCode project files (patch by Toshi Nagata)
5 - Dev-C++ (win32) project file is automatically updated with
6 the version info from configure.in
7
8 * src/DLS.cpp, src/DLS.h:
9 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
10 - fixed write support for big-endian systems
11 - improved handling of fixed length info strings - separate default
12 lengths can be specified for each INFO chunk
13 - added Resource::GenerateDLSID function
14 - write support fix: allow regions without mapped samples
15
16 * src/gig.cpp, src/gig.h:
17 - fixed segmentation fault in the gig::File destructor sequence which
18 happened when gig::Group informations were accessed before
19 - fixed write support for big-endian systems
20 - defined lengths of a fixed set of info strings. These strings
21 are saved when the file is written, even if they are empty.
22 - added missing parameter initalizations in sample, region and
23 instrument constructors
24 - clear unused fields when saving samples and regions
25 - fixed write support bugs: v3 dimension limits and chunksize
26 weren't saved, leverage controller of type controlchange
27 couldn't be saved, group name list chunk was placed wrong,
28 dimension region chunks also placed wrong
29 - added initialization of some fixed info strings in file and
30 instrument
31 - write support: files created by libgig will now have the RIFF
32 chunks in correct order
33 - write support: two previously unknown fields in dimension
34 definition are now saved
35 - added constants for gig file versions
36 - write support: the 3crc and einf chunks are now created or
37 updated when a file is saved (3crc contains sample checksums,
38 einf contains file statistics)
39 - write support: DLSID is now generated on the file and the
40 instruments
41 - write support: improved the default values for dimension region
42 parameters
43 - more write support fixes: crossfade parameters were not saved,
44 v3 dimension limits were not correctly initialized and saved
45 when dimensions were added or deleted, v3 wave pool offsets were
46 not saved correctly
47 - write support: 24 bit samples can now be written
48 - write support: version 3 is now the default for new files
49 - more write support fixes: the 3ewg chunk is now bigger for v3,
50 dimension regions without mapped samples are now allowed, 3gnl
51 list in v3 files now always has 128 entries, several parameters
52 where incorrectly saved due to an operator precedence mistake
53 - DeleteSample now removes all references to the deleted sample
54 - AddDimension now copies all parameters from existing dimension
55 regions and also makes sure that the samplechannel dimension is
56 placed first in the list of dimensions.
57 - added method GetParent() to class 'DimensionRegion', which returns its
58 parent Region
59
60 * src/RIFF.cpp, src/RIFF.h:
61 - added File::SetByteOrder method
62 - Windows fix: saving a new file didn't work
63
64 * src/gigdump.cpp:
65 - added some missing dimension strings
66
67 Version 3.1.1 (24 Mar 2007)
68
69 * packaging changes:
70 - ported to Windows using native Windows functions for file IO
71 (provided Dev-C++ + mingw project file)
72 - only export relevant files to Doxygen API documentation
73
74 * src/gig.cpp, src/gig.h:
75 - custom velocity splits now works for gig v3 files too
76 - added support for custom splits points for other dimensions than
77 velocity (gig v3 feature)
78 - added "smart midi" and "round robin keyboard" dimensions
79 - added new method File::DeleteGroupOnly() which only deletes the given
80 group but moves all its members to another group, the other method,
81 that is File::DeleteGroup() now removes not just the group, but also
82 all the samples that belong to that group
83 - fixed crash which occured on interfering File::DeleteSample() and
84 File::GetNextSample() calls (due to iterator invalidation)
85 - fixed group names which were not saved
86 - fixed group destructor which did not remove the RIFF chunk associated
87 with the group
88 - added Instrument::MoveRegion method
89 - fixed constructor for Region, which did not initialize correctly
90 when used from Instrument::AddRegion
91 - when saving, override the gig::Regions sample reference simply by
92 the region's first dimension region's sample (avoids an exception
93 when trying to save a new instrument)
94 - fixed AddDimension() method which did not fill out all mandatory
95 dimension definition fields
96
97 * src/DLS.cpp, src/DLS.h:
98 - added Instrument::MoveRegion method
99 - fixed software info field which was wrongly stored on instruments,
100 causing an exception when trying to save a new instrument
101
102 * src/RIFF.cpp, src/RIFF.h:
103 - fixed RIFF::Chunk destructor which did not unregister previously
104 resized chunks, leading to a "zero size chunk" exception when
105 File::Save() was called
106 - added List::MoveSubChunk method
107
108 Version 3.1.0 (24 Nov 2006)

119 instead of the wave chunk
120 - keyswitching dimension is changed from split type "normal" to

230 articulation informations are ignored at the moment
231 (patch by Andreas Persson)
232 - added some file format compatibility checks
233 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

283
284 * packaging changes:
285 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
286 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
287 - fixed man pages automake install rule (which didn't work on Mandrake,
288 SuSE and Fedora)
289 - fixed generation of Doxygen API documentation (now also included in
290 RPM and Debian packages)
291
292 * src/gig.cpp, src/gig.h:
293 - fixed / improved accuracy of all three velocity to volume
294 transformation functions a.k.a. 'nonlinear','linear','special'
295 (patch by Andreas Persson)
296 - denormals are filtered from the velocity to volume tables
297 - bugfix for dimension region switching (wrong handling of the release
298 trigger dimension, no bit range check for dimensions of split type
299 'split_type_bit')

301 signed 7 bit to signed 8 bit)
302 - added class attribute 'Layers' to class 'gig::Region'
303 - symbol prototyping of gig::Region (fixes build failure with qsampler)
304

317 Version 0.7.1 (2 Jul 2004)
318
319 * packaging changes:
320 - added libgig.spec and libgig.pc package configurations for generating
321 Redhat packages
322 - header files included on installation.
323 - autotools-generated files removed from CVS repository.
324 - added support for generating Debian packages
325 - version of shared library can be set in configure.in
326
327 Version 0.7.0 (3 May 2004)
328
329 * general changes:
330 - various big endian specific corrections
331 (successfully tested now on PPC)
332 - minor adjustments to avoid compile errors on some systems
333 (using now pow() instead of powl() and --pedantic g++ compiler switch)
334 - libtoolized the library
335 - added man pages for the command line tools
336 (gigextract, gigdump, dlsdump, rifftree)
337
338 * src/gig.cpp, src/gig.h:
339 - fixed bug in decompression algorithm which caused it not to detect
340 the end of a stream
341 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
342 takes the MIDI key velocity value as an argument and returns the
343 appropriate volume factor (0.0 ... 1.0) for the sample to be played
344 back, the velocity curve transformation functions used for this are
345 only an approximation so far
346 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
347 'Sample::LoopSize' which reflected wrong values
348 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
349 measured in sample points instead of byte offset
350 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
351 'Sample::FineTune'
352 - added class attribute 'Sample::LoopSize'
353 - added method GetInstrument(uint index) to class 'File'
354 - added ReadAndLoop() method to class 'Sample' which is an extension to
355 the normal Read() method to honor the sample's looping information
356 while streaming from disk
357 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
358 'eg2_ctrl_t': replaced this huge enumeration by a structure which
359 reflects the MIDI controller number in case of an ordinary control
360 change controller (this saves a huge switch-case block in the
361 application of the library user)
362 - renamed following attributes in class 'DimensionRegion':
363 'AttenuationContol' -> 'AttenuationController',
364 'InvertAttenuationControl' -> 'InvertAttenuationController',
365 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
366 - minor fix in API documentation for method GetVelocityAttenuation() in
367 class 'DimensionRegion'
368
369 * src/RIFF.cpp, src/RIFF.h:
370 - added additional API documentation
371 - minor fix in Chunk::Read() method (only a minor efficiency issue)
372
373 * src/gigdump.cpp:
374 - added printout of samples' looping informations
375
376 Version 0.6.0 (3 Nov 2003)
377
378 * initial release
