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 persson 1199 - 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 schoenebeck 1158
38 persson 1183 * src/RIFF.cpp, src/RIFF.h:
39 persson 1184 - added File::SetByteOrder method
40 persson 1183
41 schoenebeck 1116 Version 3.1.1 (24 Mar 2007)
42 schoenebeck 1050
43     * packaging changes:
44     - ported to Windows using native Windows functions for file IO
45     (provided Dev-C++ + mingw project file)
46 schoenebeck 1079 - only export relevant files to Doxygen API documentation
47 schoenebeck 1050
48 persson 1070 * 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 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
53 schoenebeck 1081 - 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 schoenebeck 1083 - fixed crash which occured on interfering File::DeleteSample() and
58     File::GetNextSample() calls (due to iterator invalidation)
59 schoenebeck 1098 - fixed group names which were not saved
60 schoenebeck 1099 - fixed group destructor which did not remove the RIFF chunk associated
61     with the group
62 persson 1102 - added Instrument::MoveRegion method
63     - fixed constructor for Region, which did not initialize correctly
64     when used from Instrument::AddRegion
65 schoenebeck 1106 - 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 schoenebeck 1113 - fixed AddDimension() method which did not fill out all mandatory
69     dimension definition fields
70 persson 1070
71 persson 1102 * src/DLS.cpp, src/DLS.h:
72     - added Instrument::MoveRegion method
73 schoenebeck 1106 - fixed software info field which was wrongly stored on instruments,
74     causing an exception when trying to save a new instrument
75 persson 1102
76 schoenebeck 1095 * 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 persson 1102 - added List::MoveSubChunk method
81 schoenebeck 1095

147     resize and write operations in one rush
148    
149 schoenebeck 809 * src/gigdump.cpp:
150     - fixed to show the correct amount of dimension regions instead of 32

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

257 schoenebeck 196
258     * packaging changes:
259     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

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

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

278 schoenebeck 231
279 schoenebeck 220 * src/gigextract.cpp:
280     - added support for libsndfile (if libaudiofile and libsndfile are

282    
283 schoenebeck 229 * src/gigdump.cpp:

290 schoenebeck 229
291 capela 168 Version 0.7.1 (2 Jul 2004)
292    
293     * packaging changes:
294 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating

298 schoenebeck 186 - added support for generating Debian packages
299     - version of shared library can be set in configure.in
300    
301 schoenebeck 58 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 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
351    
352     * initial release
