* improved the default values for dimension region parameters

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 persson 1218 - write support: improved the default values for dimension region
41     parameters
42 schoenebeck 1158
43 persson 1183 * src/RIFF.cpp, src/RIFF.h:
44 persson 1184 - added File::SetByteOrder method

48     * packaging changes:
49     - ported to Windows using native Windows functions for file IO
50     (provided Dev-C++ + mingw project file)

52 schoenebeck 1050
53 persson 1070 * src/gig.cpp, src/gig.h:
54     - custom velocity splits now works for gig v3 files too
55     - added support for custom splits points for other dimensions than
56     velocity (gig v3 feature)
57 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
58 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
59     group but moves all its members to another group, the other method,
60     that is File::DeleteGroup() now removes not just the group, but also
61     all the samples that belong to that group
62 schoenebeck 1083 - fixed crash which occured on interfering File::DeleteSample() and
63     File::GetNextSample() calls (due to iterator invalidation)
64 schoenebeck 1098 - fixed group names which were not saved
65 schoenebeck 1099 - fixed group destructor which did not remove the RIFF chunk associated
66     with the group
67 persson 1102 - added Instrument::MoveRegion method
68     - fixed constructor for Region, which did not initialize correctly
69     when used from Instrument::AddRegion
70 schoenebeck 1106 - when saving, override the gig::Regions sample reference simply by
71     the region's first dimension region's sample (avoids an exception
72     when trying to save a new instrument)
73 schoenebeck 1113 - fixed AddDimension() method which did not fill out all mandatory
74     dimension definition fields
75 persson 1070

79     causing an exception when trying to save a new instrument
80 persson 1102
81 schoenebeck 1095 * src/RIFF.cpp, src/RIFF.h:
82     - fixed RIFF::Chunk destructor which did not unregister previously
83     resized chunks, leading to a "zero size chunk" exception when
84     File::Save() was called

152     resize and write operations in one rush
153    
154 schoenebeck 809 * src/gigdump.cpp:

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

262 schoenebeck 196
263     * packaging changes:
264     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

273 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
274     (patch by Andreas Persson)
275 schoenebeck 231 - denormals are filtered from the velocity to volume tables
276 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
277     trigger dimension, no bit range check for dimensions of split type

283 schoenebeck 231
284 schoenebeck 220 * src/gigextract.cpp:
285     - added support for libsndfile (if libaudiofile and libsndfile are

295 schoenebeck 229
296 capela 168 Version 0.7.1 (2 Jul 2004)
297    
298     * packaging changes:
299 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
300     Redhat packages

302     - autotools-generated files removed from CVS repository.
303 schoenebeck 186 - added support for generating Debian packages
304     - version of shared library can be set in configure.in
305    
306 schoenebeck 58 Version 0.7.0 (3 May 2004)
307    
308     * general changes:
309     - various big endian specific corrections
310     (successfully tested now on PPC)
311     - minor adjustments to avoid compile errors on some systems
312     (using now pow() instead of powl() and --pedantic g++ compiler switch)
313     - libtoolized the library
314     - added man pages for the command line tools
315     (gigextract, gigdump, dlsdump, rifftree)
316    
317     * src/gig.cpp, src/gig.h:
318     - fixed bug in decompression algorithm which caused it not to detect
319     the end of a stream
320     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
321     takes the MIDI key velocity value as an argument and returns the
322     appropriate volume factor (0.0 ... 1.0) for the sample to be played
323     back, the velocity curve transformation functions used for this are
324     only an approximation so far
325     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
326     'Sample::LoopSize' which reflected wrong values
327     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
328     measured in sample points instead of byte offset
329     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
330     'Sample::FineTune'
331     - added class attribute 'Sample::LoopSize'
332     - added method GetInstrument(uint index) to class 'File'
333     - added ReadAndLoop() method to class 'Sample' which is an extension to
334     the normal Read() method to honor the sample's looping information
335     while streaming from disk
336     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
337     'eg2_ctrl_t': replaced this huge enumeration by a structure which
338     reflects the MIDI controller number in case of an ordinary control
339     change controller (this saves a huge switch-case block in the
340     application of the library user)
341     - renamed following attributes in class 'DimensionRegion':
342     'AttenuationContol' -> 'AttenuationController',
343     'InvertAttenuationControl' -> 'InvertAttenuationController',
344     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
345     - minor fix in API documentation for method GetVelocityAttenuation() in
346     class 'DimensionRegion'
347    
348     * src/RIFF.cpp, src/RIFF.h:
349     - added additional API documentation
350     - minor fix in Chunk::Read() method (only a minor efficiency issue)
351    
352     * src/gigdump.cpp:
353     - added printout of samples' looping informations
354    
355 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
356    
357     * initial release
