* write support fix: dimension region chunks were added in wrong list

1 schoenebeck 1154 Version CVS HEAD (?)
2    
3 schoenebeck 1172 * packaging changes:
4     - added Mac OSX XCode project files (patch by Toshi Nagata)
5 schoenebeck 1186 - Dev-C++ (win32) project file is automatically updated with
6     the version info from configure.in
7 schoenebeck 1172
8 schoenebeck 1154 * src/DLS.cpp, src/DLS.h:
9     - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
10 persson 1179 - fixed write support for big-endian systems
11 persson 1180 - improved handling of fixed length info strings - separate default
12     lengths can be specified for each INFO chunk
13 schoenebeck 1154
14 schoenebeck 1158 * 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 persson 1179 - fixed write support for big-endian systems
18 persson 1180 - 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 persson 1182 - 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 persson 1195 couldn't be saved, group name list chunk was placed wrong,
26     dimension region chunks also placed wrong
27 persson 1182 - added initialization of some fixed info strings in file and
28     instrument
29 persson 1192 - write support: files created by libgig will now have the RIFF
30     chunks in correct order
31 schoenebeck 1158
32 persson 1183 * src/RIFF.cpp, src/RIFF.h:
33 persson 1184 - added File::SetByteOrder method
34 persson 1183
35 schoenebeck 1116 Version 3.1.1 (24 Mar 2007)
36 schoenebeck 1050
37     * packaging changes:
38     - ported to Windows using native Windows functions for file IO
39     (provided Dev-C++ + mingw project file)
40 schoenebeck 1079 - only export relevant files to Doxygen API documentation
41 schoenebeck 1050
42 persson 1070 * src/gig.cpp, src/gig.h:
43     - custom velocity splits now works for gig v3 files too
44     - added support for custom splits points for other dimensions than
45     velocity (gig v3 feature)
46 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
47 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
48     group but moves all its members to another group, the other method,
49     that is File::DeleteGroup() now removes not just the group, but also
50     all the samples that belong to that group
51 schoenebeck 1083 - fixed crash which occured on interfering File::DeleteSample() and
52     File::GetNextSample() calls (due to iterator invalidation)
53 schoenebeck 1098 - fixed group names which were not saved
54 schoenebeck 1099 - fixed group destructor which did not remove the RIFF chunk associated
55     with the group
56 persson 1102 - added Instrument::MoveRegion method
57     - fixed constructor for Region, which did not initialize correctly
58     when used from Instrument::AddRegion
59 schoenebeck 1106 - when saving, override the gig::Regions sample reference simply by
60     the region's first dimension region's sample (avoids an exception
61     when trying to save a new instrument)
62 schoenebeck 1113 - fixed AddDimension() method which did not fill out all mandatory
63     dimension definition fields
64 persson 1070
65 persson 1102 * src/DLS.cpp, src/DLS.h:
66     - added Instrument::MoveRegion method
67 schoenebeck 1106 - fixed software info field which was wrongly stored on instruments,
68     causing an exception when trying to save a new instrument
69 persson 1102
70 schoenebeck 1095 * src/RIFF.cpp, src/RIFF.h:
71     - fixed RIFF::Chunk destructor which did not unregister previously
72     resized chunks, leading to a "zero size chunk" exception when
73     File::Save() was called
74 persson 1102 - added List::MoveSubChunk method
75 schoenebeck 1095

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

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

272 schoenebeck 231
273 schoenebeck 220 * src/gigextract.cpp:
274     - added support for libsndfile (if libaudiofile and libsndfile are

285 capela 168 Version 0.7.1 (2 Jul 2004)
286    
287     * packaging changes:

292 schoenebeck 186 - added support for generating Debian packages
293     - version of shared library can be set in configure.in
294    
295 schoenebeck 58 Version 0.7.0 (3 May 2004)
296    
297     * general changes:
298     - various big endian specific corrections
299     (successfully tested now on PPC)
300     - minor adjustments to avoid compile errors on some systems
301     (using now pow() instead of powl() and --pedantic g++ compiler switch)
302     - libtoolized the library
303     - added man pages for the command line tools
304     (gigextract, gigdump, dlsdump, rifftree)
305    
306     * src/gig.cpp, src/gig.h:
307     - fixed bug in decompression algorithm which caused it not to detect
308     the end of a stream
309     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
310     takes the MIDI key velocity value as an argument and returns the
311     appropriate volume factor (0.0 ... 1.0) for the sample to be played
312     back, the velocity curve transformation functions used for this are
313     only an approximation so far
314     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
315     'Sample::LoopSize' which reflected wrong values
316     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
317     measured in sample points instead of byte offset
318     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
319     'Sample::FineTune'
320     - added class attribute 'Sample::LoopSize'
321     - added method GetInstrument(uint index) to class 'File'
322     - added ReadAndLoop() method to class 'Sample' which is an extension to
323     the normal Read() method to honor the sample's looping information
324     while streaming from disk
325     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
326     'eg2_ctrl_t': replaced this huge enumeration by a structure which
327     reflects the MIDI controller number in case of an ordinary control
328     change controller (this saves a huge switch-case block in the
329     application of the library user)
330     - renamed following attributes in class 'DimensionRegion':
331     'AttenuationContol' -> 'AttenuationController',
332     'InvertAttenuationControl' -> 'InvertAttenuationController',
333     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
334     - minor fix in API documentation for method GetVelocityAttenuation() in
335     class 'DimensionRegion'
336    
337     * src/RIFF.cpp, src/RIFF.h:
338     - added additional API documentation
339     - minor fix in Chunk::Read() method (only a minor efficiency issue)
340    
341     * src/gigdump.cpp:
342     - added printout of samples' looping informations
343    
344 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
345    
346     * initial release
