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 persson 1183 * src/RIFF.cpp, src/RIFF.h:
28     - added constructor for File where endianess (RIFF/RIFX) can be
29     specified
30    
31 schoenebeck 1116 Version 3.1.1 (24 Mar 2007)
32 schoenebeck 1050
33     * packaging changes:
34     - ported to Windows using native Windows functions for file IO
35     (provided Dev-C++ + mingw project file)
36 schoenebeck 1079 - only export relevant files to Doxygen API documentation
37 schoenebeck 1050
38 persson 1070 * src/gig.cpp, src/gig.h:
39     - custom velocity splits now works for gig v3 files too
40     - added support for custom splits points for other dimensions than
41     velocity (gig v3 feature)
42 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
43 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
44     group but moves all its members to another group, the other method,
45     that is File::DeleteGroup() now removes not just the group, but also
46     all the samples that belong to that group
47 schoenebeck 1083 - fixed crash which occured on interfering File::DeleteSample() and
48     File::GetNextSample() calls (due to iterator invalidation)
49 schoenebeck 1098 - fixed group names which were not saved
50 schoenebeck 1099 - fixed group destructor which did not remove the RIFF chunk associated
51     with the group
52 persson 1102 - added Instrument::MoveRegion method
53     - fixed constructor for Region, which did not initialize correctly
54     when used from Instrument::AddRegion
55 schoenebeck 1106 - when saving, override the gig::Regions sample reference simply by
56     the region's first dimension region's sample (avoids an exception
57     when trying to save a new instrument)
58 schoenebeck 1113 - fixed AddDimension() method which did not fill out all mandatory
59     dimension definition fields
60 persson 1070
61 persson 1102 * src/DLS.cpp, src/DLS.h:
62     - added Instrument::MoveRegion method
63 schoenebeck 1106 - fixed software info field which was wrongly stored on instruments,
64     causing an exception when trying to save a new instrument
65 persson 1102
66 schoenebeck 1095 * src/RIFF.cpp, src/RIFF.h:
67     - fixed RIFF::Chunk destructor which did not unregister previously
68     resized chunks, leading to a "zero size chunk" exception when
69     File::Save() was called
70 persson 1102 - added List::MoveSubChunk method
71 schoenebeck 1095

137     resize and write operations in one rush
138    
139 schoenebeck 809 * src/gigdump.cpp:
140     - fixed to show the correct amount of dimension regions instead of 32

197 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

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

268 schoenebeck 231
269 schoenebeck 220 * src/gigextract.cpp:
270     - added support for libsndfile (if libaudiofile and libsndfile are

280 schoenebeck 229
281 capela 168 Version 0.7.1 (2 Jul 2004)
282    
283     * packaging changes:
284 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
285     Redhat packages

288 schoenebeck 186 - added support for generating Debian packages
289     - version of shared library can be set in configure.in
290    
291 schoenebeck 58 Version 0.7.0 (3 May 2004)
292    
293     * general changes:
294     - various big endian specific corrections
295     (successfully tested now on PPC)
296     - minor adjustments to avoid compile errors on some systems
297     (using now pow() instead of powl() and --pedantic g++ compiler switch)
298     - libtoolized the library
299     - added man pages for the command line tools
300     (gigextract, gigdump, dlsdump, rifftree)
301    
302     * src/gig.cpp, src/gig.h:
303     - fixed bug in decompression algorithm which caused it not to detect
304     the end of a stream
305     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
306     takes the MIDI key velocity value as an argument and returns the
307     appropriate volume factor (0.0 ... 1.0) for the sample to be played
308     back, the velocity curve transformation functions used for this are
309     only an approximation so far
310     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
311     'Sample::LoopSize' which reflected wrong values
312     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
313     measured in sample points instead of byte offset
314     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
315     'Sample::FineTune'
316     - added class attribute 'Sample::LoopSize'
317     - added method GetInstrument(uint index) to class 'File'
318     - added ReadAndLoop() method to class 'Sample' which is an extension to
319     the normal Read() method to honor the sample's looping information
320     while streaming from disk
321     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
322     'eg2_ctrl_t': replaced this huge enumeration by a structure which
323     reflects the MIDI controller number in case of an ordinary control
324     change controller (this saves a huge switch-case block in the
325     application of the library user)
326     - renamed following attributes in class 'DimensionRegion':
327     'AttenuationContol' -> 'AttenuationController',
328     'InvertAttenuationControl' -> 'InvertAttenuationController',
329     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
330     - minor fix in API documentation for method GetVelocityAttenuation() in
331     class 'DimensionRegion'
332    
333     * src/RIFF.cpp, src/RIFF.h:
334     - added additional API documentation
335     - minor fix in Chunk::Read() method (only a minor efficiency issue)
336    
337     * src/gigdump.cpp:
338     - added printout of samples' looping informations
339    
340 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
341    
342     * initial release
