* improved handling of fixed length info strings

1 schoenebeck 1154 Version CVS HEAD (?)
2    
3 schoenebeck 1172 * packaging changes:
4     - added Mac OSX XCode project files (patch by Toshi Nagata)
5    
6 schoenebeck 1154 * src/DLS.cpp, src/DLS.h:
7     - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
8 persson 1179 - fixed write support for big-endian systems
9 persson 1180 - improved handling of fixed length info strings - separate default
10     lengths can be specified for each INFO chunk
11 schoenebeck 1154
12 schoenebeck 1158 * src/gig.cpp, src/gig.h:
13     - fixed segmentation fault in the gig::File destructor sequence which
14     happened when gig::Group informations were accessed before
15 persson 1179 - fixed write support for big-endian systems
16 persson 1180 - defined lengths of a fixed set of info strings. These strings
17     are saved when the file is written, even if they are empty.
18 schoenebeck 1158
19 schoenebeck 1116 Version 3.1.1 (24 Mar 2007)
20 schoenebeck 1050
21     * packaging changes:
22     - ported to Windows using native Windows functions for file IO
23     (provided Dev-C++ + mingw project file)
24 schoenebeck 1079 - only export relevant files to Doxygen API documentation
25 schoenebeck 1050
26 persson 1070 * src/gig.cpp, src/gig.h:
27     - custom velocity splits now works for gig v3 files too
28     - added support for custom splits points for other dimensions than
29     velocity (gig v3 feature)
30 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
31 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
32     group but moves all its members to another group, the other method,
33     that is File::DeleteGroup() now removes not just the group, but also
34     all the samples that belong to that group
35 schoenebeck 1083 - fixed crash which occured on interfering File::DeleteSample() and
36     File::GetNextSample() calls (due to iterator invalidation)
37 schoenebeck 1098 - fixed group names which were not saved
38 schoenebeck 1099 - fixed group destructor which did not remove the RIFF chunk associated
39     with the group

42     when used from Instrument::AddRegion
43 schoenebeck 1106 - when saving, override the gig::Regions sample reference simply by
44     the region's first dimension region's sample (avoids an exception
45     when trying to save a new instrument)

47     dimension definition fields
48 persson 1070

54 schoenebeck 1095 * src/RIFF.cpp, src/RIFF.h:
55     - fixed RIFF::Chunk destructor which did not unregister previously
56     resized chunks, leading to a "zero size chunk" exception when
57     File::Save() was called
58 persson 1102 - added List::MoveSubChunk method

125     resize and write operations in one rush
126    
127 schoenebeck 809 * src/gigdump.cpp:
128     - fixed to show the correct amount of dimension regions instead of 32

184 schoenebeck 317 - added some file format compatibility checks
185 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

236     * packaging changes:
237     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

246 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
247     (patch by Andreas Persson)
248 schoenebeck 231 - denormals are filtered from the velocity to volume tables
249 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
250     trigger dimension, no bit range check for dimensions of split type
251     'split_type_bit')
252 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from

254 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
255 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
256 schoenebeck 231
257 schoenebeck 220 * src/gigextract.cpp:
258     - added support for libsndfile (if libaudiofile and libsndfile are

260    
261 schoenebeck 229 * src/gigdump.cpp:
262     - added printout for dimension informations (amount, type, bits, zones)

267     Gigasampler layers
268 schoenebeck 229
269 capela 168 Version 0.7.1 (2 Jul 2004)
270    
271     * packaging changes:
272 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
273     Redhat packages

276 schoenebeck 186 - added support for generating Debian packages
277     - version of shared library can be set in configure.in
278    
279 schoenebeck 58 Version 0.7.0 (3 May 2004)
280    
281     * general changes:
282     - various big endian specific corrections
283     (successfully tested now on PPC)
284     - minor adjustments to avoid compile errors on some systems
285     (using now pow() instead of powl() and --pedantic g++ compiler switch)
286     - libtoolized the library
287     - added man pages for the command line tools
288     (gigextract, gigdump, dlsdump, rifftree)
289    
290     * src/gig.cpp, src/gig.h:
291     - fixed bug in decompression algorithm which caused it not to detect
292     the end of a stream
293     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
294     takes the MIDI key velocity value as an argument and returns the
295     appropriate volume factor (0.0 ... 1.0) for the sample to be played
296     back, the velocity curve transformation functions used for this are
297     only an approximation so far
298     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
299     'Sample::LoopSize' which reflected wrong values
300     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
301     measured in sample points instead of byte offset
302     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
303     'Sample::FineTune'
304     - added class attribute 'Sample::LoopSize'
305     - added method GetInstrument(uint index) to class 'File'
306     - added ReadAndLoop() method to class 'Sample' which is an extension to
307     the normal Read() method to honor the sample's looping information
308     while streaming from disk
309     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
310     'eg2_ctrl_t': replaced this huge enumeration by a structure which
311     reflects the MIDI controller number in case of an ordinary control
312     change controller (this saves a huge switch-case block in the
313     application of the library user)
314     - renamed following attributes in class 'DimensionRegion':
315     'AttenuationContol' -> 'AttenuationController',
316     'InvertAttenuationControl' -> 'InvertAttenuationController',
317     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
318     - minor fix in API documentation for method GetVelocityAttenuation() in
319     class 'DimensionRegion'
320    
321     * src/RIFF.cpp, src/RIFF.h:
322     - added additional API documentation
323     - minor fix in Chunk::Read() method (only a minor efficiency issue)
324    
325     * src/gigdump.cpp:
326     - added printout of samples' looping informations
327    
328 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
329    
330     * initial release
