* added DLSID support

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 persson 1209 - added Resource::GenerateDLSID function
14 schoenebeck 1154
15 schoenebeck 1158 * src/gig.cpp, src/gig.h:
16     - fixed segmentation fault in the gig::File destructor sequence which
17     happened when gig::Group informations were accessed before
18 persson 1179 - fixed write support for big-endian systems
19 persson 1180 - defined lengths of a fixed set of info strings. These strings
20     are saved when the file is written, even if they are empty.
21 persson 1182 - added missing parameter initalizations in sample, region and
22     instrument constructors
23     - clear unused fields when saving samples and regions
24     - fixed write support bugs: v3 dimension limits and chunksize
25     weren't saved, leverage controller of type controlchange
26 persson 1195 couldn't be saved, group name list chunk was placed wrong,
27     dimension region chunks also placed wrong
28 persson 1182 - added initialization of some fixed info strings in file and
29     instrument
30 persson 1192 - write support: files created by libgig will now have the RIFF
31     chunks in correct order
32 persson 1199 - write support: two previously unknown fields in dimension
33     definition are now saved
34     - added constants for gig file versions
35     - write support: the 3crc and einf chunks are now created or
36     updated when a file is saved (3crc contains sample checksums,
37     einf contains file statistics)
38 persson 1209 - write support: DLSID is now generated on the file and the
39     instruments
40 schoenebeck 1158
41 persson 1183 * src/RIFF.cpp, src/RIFF.h:
42 persson 1184 - added File::SetByteOrder method

50 schoenebeck 1050
51 persson 1070 * src/gig.cpp, src/gig.h:
52     - custom velocity splits now works for gig v3 files too

54     velocity (gig v3 feature)
55 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
56 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
57     group but moves all its members to another group, the other method,
58     that is File::DeleteGroup() now removes not just the group, but also
59     all the samples that belong to that group
60 schoenebeck 1083 - fixed crash which occured on interfering File::DeleteSample() and
61     File::GetNextSample() calls (due to iterator invalidation)
62 schoenebeck 1098 - fixed group names which were not saved
63 schoenebeck 1099 - fixed group destructor which did not remove the RIFF chunk associated
64     with the group
65 persson 1102 - added Instrument::MoveRegion method
66     - fixed constructor for Region, which did not initialize correctly
67     when used from Instrument::AddRegion
68 schoenebeck 1106 - when saving, override the gig::Regions sample reference simply by
69     the region's first dimension region's sample (avoids an exception
70     when trying to save a new instrument)
71 schoenebeck 1113 - fixed AddDimension() method which did not fill out all mandatory
72     dimension definition fields
73 persson 1070

78 persson 1102
79 schoenebeck 1095 * src/RIFF.cpp, src/RIFF.h:
80     - fixed RIFF::Chunk destructor which did not unregister previously
81     resized chunks, leading to a "zero size chunk" exception when
82     File::Save() was called
83 persson 1102 - added List::MoveSubChunk method

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

272     (patch by Andreas Persson)
273 schoenebeck 231 - denormals are filtered from the velocity to volume tables
274 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
275     trigger dimension, no bit range check for dimensions of split type

301 schoenebeck 186 - added support for generating Debian packages
302     - version of shared library can be set in configure.in
303    
304 schoenebeck 58 Version 0.7.0 (3 May 2004)
305    
306     * general changes:
307     - various big endian specific corrections
308     (successfully tested now on PPC)
309     - minor adjustments to avoid compile errors on some systems
310     (using now pow() instead of powl() and --pedantic g++ compiler switch)
311     - libtoolized the library
312     - added man pages for the command line tools
313     (gigextract, gigdump, dlsdump, rifftree)
314    
315     * src/gig.cpp, src/gig.h:
316     - fixed bug in decompression algorithm which caused it not to detect
317     the end of a stream
318     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
319     takes the MIDI key velocity value as an argument and returns the
320     appropriate volume factor (0.0 ... 1.0) for the sample to be played
321     back, the velocity curve transformation functions used for this are
322     only an approximation so far
323     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
324     'Sample::LoopSize' which reflected wrong values
325     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
326     measured in sample points instead of byte offset
327     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
328     'Sample::FineTune'
329     - added class attribute 'Sample::LoopSize'
330     - added method GetInstrument(uint index) to class 'File'
331     - added ReadAndLoop() method to class 'Sample' which is an extension to
332     the normal Read() method to honor the sample's looping information
333     while streaming from disk
334     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
335     'eg2_ctrl_t': replaced this huge enumeration by a structure which
336     reflects the MIDI controller number in case of an ordinary control
337     change controller (this saves a huge switch-case block in the
338     application of the library user)
339     - renamed following attributes in class 'DimensionRegion':
340     'AttenuationContol' -> 'AttenuationController',
341     'InvertAttenuationControl' -> 'InvertAttenuationController',
342     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
343     - minor fix in API documentation for method GetVelocityAttenuation() in
344     class 'DimensionRegion'
345    
346     * src/RIFF.cpp, src/RIFF.h:
347     - added additional API documentation
348     - minor fix in Chunk::Read() method (only a minor efficiency issue)
349    
350     * src/gigdump.cpp:
351     - added printout of samples' looping informations
352    
353 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
354    
355     * initial release
