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 persson 1182 - added missing parameter initalizations in sample, region and
19     instrument constructors
20     - clear unused fields when saving samples and regions
21     - fixed write support bugs: v3 dimension limits and chunksize
22     weren't saved, leverage controller of type controlchange
23     couldn't be saved, group name list chunk was placed wrong
24     - added initialization of some fixed info strings in file and
25     instrument
26 schoenebeck 1158
27 schoenebeck 1116 Version 3.1.1 (24 Mar 2007)
28 schoenebeck 1050
29     * packaging changes:
30     - ported to Windows using native Windows functions for file IO
31     (provided Dev-C++ + mingw project file)
32 schoenebeck 1079 - only export relevant files to Doxygen API documentation
33 schoenebeck 1050
34 persson 1070 * src/gig.cpp, src/gig.h:
35     - custom velocity splits now works for gig v3 files too
36     - added support for custom splits points for other dimensions than
37     velocity (gig v3 feature)
38 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
39 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
40     group but moves all its members to another group, the other method,
41     that is File::DeleteGroup() now removes not just the group, but also
42     all the samples that belong to that group
43 schoenebeck 1083 - fixed crash which occured on interfering File::DeleteSample() and
44     File::GetNextSample() calls (due to iterator invalidation)
45 schoenebeck 1098 - fixed group names which were not saved

47     with the group
48 persson 1102 - added Instrument::MoveRegion method
49     - fixed constructor for Region, which did not initialize correctly
50     when used from Instrument::AddRegion

52     the region's first dimension region's sample (avoids an exception
53     when trying to save a new instrument)
54 schoenebeck 1113 - fixed AddDimension() method which did not fill out all mandatory
55     dimension definition fields
56 persson 1070

60     causing an exception when trying to save a new instrument
61 persson 1102
62 schoenebeck 1095 * src/RIFF.cpp, src/RIFF.h:
63     - fixed RIFF::Chunk destructor which did not unregister previously
64     resized chunks, leading to a "zero size chunk" exception when
65     File::Save() was called
66 persson 1102 - added List::MoveSubChunk method
67 schoenebeck 1095

133     resize and write operations in one rush
134    
135 schoenebeck 809 * src/gigdump.cpp:
136     - fixed to show the correct amount of dimension regions instead of 32

193 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

243 schoenebeck 196
244     * packaging changes:
245     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
246     'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix

248     SuSE and Fedora)
249     - fixed generation of Doxygen API documentation (now also included in

254 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
255     (patch by Andreas Persson)
256 schoenebeck 231 - denormals are filtered from the velocity to volume tables
257 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
258     trigger dimension, no bit range check for dimensions of split type
259     'split_type_bit')
260 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
261     signed 7 bit to signed 8 bit)
262 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
263 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
264 schoenebeck 231
265 schoenebeck 220 * src/gigextract.cpp:
266     - added support for libsndfile (if libaudiofile and libsndfile are
267     available then libsndfile is preferred)
268    
269 schoenebeck 229 * src/gigdump.cpp:
270     - added printout for dimension informations (amount, type, bits, zones)
271 schoenebeck 231 - added printout for velocity response curve parameters
272 schoenebeck 235 - added printout for crossfade definitions

275     Gigasampler layers
276 schoenebeck 229
277 capela 168 Version 0.7.1 (2 Jul 2004)
278    
279     * packaging changes:
280 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
281     Redhat packages

283     - autotools-generated files removed from CVS repository.
284 schoenebeck 186 - added support for generating Debian packages
285     - version of shared library can be set in configure.in
286    
287 schoenebeck 58 Version 0.7.0 (3 May 2004)
288    
289     * general changes:
290     - various big endian specific corrections
291     (successfully tested now on PPC)
292     - minor adjustments to avoid compile errors on some systems
293     (using now pow() instead of powl() and --pedantic g++ compiler switch)
294     - libtoolized the library
295     - added man pages for the command line tools
296     (gigextract, gigdump, dlsdump, rifftree)
297    
298     * src/gig.cpp, src/gig.h:
299     - fixed bug in decompression algorithm which caused it not to detect
300     the end of a stream
301     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
302     takes the MIDI key velocity value as an argument and returns the
303     appropriate volume factor (0.0 ... 1.0) for the sample to be played
304     back, the velocity curve transformation functions used for this are
305     only an approximation so far
306     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
307     'Sample::LoopSize' which reflected wrong values
308     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
309     measured in sample points instead of byte offset
310     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
311     'Sample::FineTune'
312     - added class attribute 'Sample::LoopSize'
313     - added method GetInstrument(uint index) to class 'File'
314     - added ReadAndLoop() method to class 'Sample' which is an extension to
315     the normal Read() method to honor the sample's looping information
316     while streaming from disk
317     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
318     'eg2_ctrl_t': replaced this huge enumeration by a structure which
319     reflects the MIDI controller number in case of an ordinary control
320     change controller (this saves a huge switch-case block in the
321     application of the library user)
322     - renamed following attributes in class 'DimensionRegion':
323     'AttenuationContol' -> 'AttenuationController',
324     'InvertAttenuationControl' -> 'InvertAttenuationController',
325     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
326     - minor fix in API documentation for method GetVelocityAttenuation() in
327     class 'DimensionRegion'
328    
329     * src/RIFF.cpp, src/RIFF.h:
330     - added additional API documentation
331     - minor fix in Chunk::Read() method (only a minor efficiency issue)
332    
333     * src/gigdump.cpp:
334     - added printout of samples' looping informations
335    
336 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
337    
338     * initial release
