File size: 14913 byte(s)
* added write support for the 3crc and einf chunks
* two previously unknown fields in dimension definition are now saved
* added constants for gig file versions

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
14 * src/gig.cpp, src/gig.h:
15 - fixed segmentation fault in the gig::File destructor sequence which
16 happened when gig::Group informations were accessed before
17 - fixed write support for big-endian systems
18 - defined lengths of a fixed set of info strings. These strings
19 are saved when the file is written, even if they are empty.
20 - added missing parameter initalizations in sample, region and
21 instrument constructors
22 - clear unused fields when saving samples and regions
23 - fixed write support bugs: v3 dimension limits and chunksize
24 weren't saved, leverage controller of type controlchange
25 couldn't be saved, group name list chunk was placed wrong,
26 dimension region chunks also placed wrong
27 - added initialization of some fixed info strings in file and
28 instrument
29 - write support: files created by libgig will now have the RIFF
30 chunks in correct order
31 - write support: two previously unknown fields in dimension
32 definition are now saved
33 - added constants for gig file versions
34 - write support: the 3crc and einf chunks are now created or
35 updated when a file is saved (3crc contains sample checksums,
36 einf contains file statistics)
37
38 * src/RIFF.cpp, src/RIFF.h:
39 - added File::SetByteOrder method
40
41 Version 3.1.1 (24 Mar 2007)
42
43 * packaging changes:
44 - ported to Windows using native Windows functions for file IO
45 (provided Dev-C++ + mingw project file)
46 - only export relevant files to Doxygen API documentation
47
48 * src/gig.cpp, src/gig.h:
49 - custom velocity splits now works for gig v3 files too
50 - added support for custom splits points for other dimensions than
51 velocity (gig v3 feature)
52 - added "smart midi" and "round robin keyboard" dimensions
53 - added new method File::DeleteGroupOnly() which only deletes the given
54 group but moves all its members to another group, the other method,
55 that is File::DeleteGroup() now removes not just the group, but also
56 all the samples that belong to that group
57 - fixed crash which occured on interfering File::DeleteSample() and
58 File::GetNextSample() calls (due to iterator invalidation)
59 - fixed group names which were not saved
60 - fixed group destructor which did not remove the RIFF chunk associated
61 with the group
62 - added Instrument::MoveRegion method
63 - fixed constructor for Region, which did not initialize correctly
64 when used from Instrument::AddRegion
65 - when saving, override the gig::Regions sample reference simply by
66 the region's first dimension region's sample (avoids an exception
67 when trying to save a new instrument)
68 - fixed AddDimension() method which did not fill out all mandatory
69 dimension definition fields
70
71 * src/DLS.cpp, src/DLS.h:
72 - added Instrument::MoveRegion method
73 - fixed software info field which was wrongly stored on instruments,
74 causing an exception when trying to save a new instrument
75
76 * src/RIFF.cpp, src/RIFF.h:
77 - fixed RIFF::Chunk destructor which did not unregister previously
78 resized chunks, leading to a "zero size chunk" exception when
79 File::Save() was called
80 - added List::MoveSubChunk method
81
82 Version 3.1.0 (24 Nov 2006)
83
84 * packaging changes:
85 - changed deprecated copyright attribute to license;
86 added ldconfig to post-(un)install steps on libgig.spec (RPM)
87
88 * src/gig.cpp, src/gig.h:

90 inside a region (for example different velocity split levels for
91 pedal up and pedal down)

93 instead of the wave chunk
94 - keyswitching dimension is changed from split type "normal" to
95 "bit"

101 - support for sample groups added
102
103 * src/DLS.cpp, src/DLS.h:

134 splits not equal to a power of two
135 - added write support (highly experimental)

204 articulation informations are ignored at the moment
205 (patch by Andreas Persson)
206 - added some file format compatibility checks
207 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

262 SuSE and Fedora)
263 - fixed generation of Doxygen API documentation (now also included in
264 RPM and Debian packages)
265
266 * src/gig.cpp, src/gig.h:
267 - fixed / improved accuracy of all three velocity to volume
268 transformation functions a.k.a. 'nonlinear','linear','special'
269 (patch by Andreas Persson)
270 - denormals are filtered from the velocity to volume tables
271 - bugfix for dimension region switching (wrong handling of the release
272 trigger dimension, no bit range check for dimensions of split type

299 - version of shared library can be set in configure.in
300
301 Version 0.7.0 (3 May 2004)
302
303 * general changes:
304 - various big endian specific corrections
305 (successfully tested now on PPC)
306 - minor adjustments to avoid compile errors on some systems
307 (using now pow() instead of powl() and --pedantic g++ compiler switch)
308 - libtoolized the library
309 - added man pages for the command line tools
310 (gigextract, gigdump, dlsdump, rifftree)
311
312 * src/gig.cpp, src/gig.h:
313 - fixed bug in decompression algorithm which caused it not to detect
314 the end of a stream
315 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
316 takes the MIDI key velocity value as an argument and returns the
317 appropriate volume factor (0.0 ... 1.0) for the sample to be played
318 back, the velocity curve transformation functions used for this are
319 only an approximation so far
320 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
321 'Sample::LoopSize' which reflected wrong values
322 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
323 measured in sample points instead of byte offset
324 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
325 'Sample::FineTune'
326 - added class attribute 'Sample::LoopSize'
327 - added method GetInstrument(uint index) to class 'File'
328 - added ReadAndLoop() method to class 'Sample' which is an extension to
329 the normal Read() method to honor the sample's looping information
330 while streaming from disk
331 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
332 'eg2_ctrl_t': replaced this huge enumeration by a structure which
333 reflects the MIDI controller number in case of an ordinary control
334 change controller (this saves a huge switch-case block in the
335 application of the library user)
336 - renamed following attributes in class 'DimensionRegion':
337 'AttenuationContol' -> 'AttenuationController',
338 'InvertAttenuationControl' -> 'InvertAttenuationController',
339 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
340 - minor fix in API documentation for method GetVelocityAttenuation() in
341 class 'DimensionRegion'
342
343 * src/RIFF.cpp, src/RIFF.h:
344 - added additional API documentation
345 - minor fix in Chunk::Read() method (only a minor efficiency issue)
346
347 * src/gigdump.cpp:
348 - added printout of samples' looping informations
349
350 Version 0.6.0 (3 Nov 2003)
351
352 * initial release
