File size: 16632 byte(s)
* added virtual method SetKeyRange() to the gig and DLS Region classes,
  which automatically take care that the "resized" Region is at the
  correct position and that the lookup table for
  gig::Instrument::GetRegion() is updated (moved code from gigedit)
* MoveRegion() method of DLS::Region class is now private
* bugfix: gig::Instrument::UpdateRegionKeyTable() did not reset unused
  areas

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 persson 1330 - the configure script can now be used in Windows with MSYS
8 schoenebeck 1172
9 schoenebeck 1154 * src/DLS.cpp, src/DLS.h:
10     - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
11 persson 1179 - fixed write support for big-endian systems
12 persson 1180 - improved handling of fixed length info strings - separate default
13     lengths can be specified for each INFO chunk
14 persson 1209 - added Resource::GenerateDLSID function
15 persson 1266 - write support fix: allow regions without mapped samples
16 schoenebeck 1335 - added method SetKeyRange() to the Region class which should be used
17     instead of setting the KeyRange member variable directly
18     - MoveRegion() method of Region class is now private
19 schoenebeck 1154
20 schoenebeck 1158 * src/gig.cpp, src/gig.h:
21     - fixed segmentation fault in the gig::File destructor sequence which
22     happened when gig::Group informations were accessed before
23 persson 1179 - fixed write support for big-endian systems
24 persson 1180 - defined lengths of a fixed set of info strings. These strings
25     are saved when the file is written, even if they are empty.
26 persson 1182 - added missing parameter initalizations in sample, region and
27     instrument constructors
28     - clear unused fields when saving samples and regions
29     - fixed write support bugs: v3 dimension limits and chunksize
30     weren't saved, leverage controller of type controlchange
31 persson 1195 couldn't be saved, group name list chunk was placed wrong,
32     dimension region chunks also placed wrong
33 persson 1182 - added initialization of some fixed info strings in file and
34     instrument
35 persson 1192 - write support: files created by libgig will now have the RIFF
36     chunks in correct order
37 persson 1199 - write support: two previously unknown fields in dimension
38     definition are now saved
39     - added constants for gig file versions
40     - write support: the 3crc and einf chunks are now created or
41     updated when a file is saved (3crc contains sample checksums,
42     einf contains file statistics)
43 persson 1209 - write support: DLSID is now generated on the file and the
44     instruments
45 persson 1218 - write support: improved the default values for dimension region
46     parameters
47 persson 1247 - more write support fixes: crossfade parameters were not saved,
48     v3 dimension limits were not correctly initialized and saved
49     when dimensions were added or deleted, v3 wave pool offsets were
50     not saved correctly
51 persson 1264 - write support: 24 bit samples can now be written
52     - write support: version 3 is now the default for new files
53 persson 1266 - more write support fixes: the 3ewg chunk is now bigger for v3,
54     dimension regions without mapped samples are now allowed, 3gnl
55     list in v3 files now always has 128 entries, several parameters
56     where incorrectly saved due to an operator precedence mistake
57     - DeleteSample now removes all references to the deleted sample
58 persson 1301 - AddDimension now copies all parameters from existing dimension
59     regions and also makes sure that the samplechannel dimension is
60     placed first in the list of dimensions.
61 schoenebeck 1316 - added method GetParent() to class 'DimensionRegion', which returns its
62     parent Region
63 schoenebeck 1335 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
64     unused areas

72    
73 schoenebeck 1116 Version 3.1.1 (24 Mar 2007)
74 schoenebeck 1050
75     * packaging changes:

84 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
85 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
86     group but moves all its members to another group, the other method,
87     that is File::DeleteGroup() now removes not just the group, but also
88     all the samples that belong to that group
89 schoenebeck 1083 - fixed crash which occured on interfering File::DeleteSample() and

111     File::Save() was called
112 persson 1102 - added List::MoveSubChunk method

239 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

305     'split_type_bit')
306 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
307     signed 7 bit to signed 8 bit)
308 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
309 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
310 schoenebeck 231
311 schoenebeck 220 * src/gigextract.cpp:
312     - added support for libsndfile (if libaudiofile and libsndfile are

323 capela 168 Version 0.7.1 (2 Jul 2004)
324    
325     * packaging changes:
326 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
327     Redhat packages
328 capela 168 - header files included on installation.
329     - autotools-generated files removed from CVS repository.
330 schoenebeck 186 - added support for generating Debian packages
331     - version of shared library can be set in configure.in
332    
333 schoenebeck 58 Version 0.7.0 (3 May 2004)
334    
335     * general changes:
336     - various big endian specific corrections
337     (successfully tested now on PPC)
338     - minor adjustments to avoid compile errors on some systems
339     (using now pow() instead of powl() and --pedantic g++ compiler switch)
340     - libtoolized the library
341     - added man pages for the command line tools
342     (gigextract, gigdump, dlsdump, rifftree)
343    
344     * src/gig.cpp, src/gig.h:
345     - fixed bug in decompression algorithm which caused it not to detect
346     the end of a stream
347     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
348     takes the MIDI key velocity value as an argument and returns the
349     appropriate volume factor (0.0 ... 1.0) for the sample to be played
350     back, the velocity curve transformation functions used for this are
351     only an approximation so far
352     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
353     'Sample::LoopSize' which reflected wrong values
354     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
355     measured in sample points instead of byte offset
356     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
357     'Sample::FineTune'
358     - added class attribute 'Sample::LoopSize'
359     - added method GetInstrument(uint index) to class 'File'
360     - added ReadAndLoop() method to class 'Sample' which is an extension to
361     the normal Read() method to honor the sample's looping information
362     while streaming from disk
363     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
364     'eg2_ctrl_t': replaced this huge enumeration by a structure which
365     reflects the MIDI controller number in case of an ordinary control
366     change controller (this saves a huge switch-case block in the
367     application of the library user)
368     - renamed following attributes in class 'DimensionRegion':
369     'AttenuationContol' -> 'AttenuationController',
370     'InvertAttenuationControl' -> 'InvertAttenuationController',
371     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
372     - minor fix in API documentation for method GetVelocityAttenuation() in
373     class 'DimensionRegion'
374    
375     * src/RIFF.cpp, src/RIFF.h:
376     - added additional API documentation
377     - minor fix in Chunk::Read() method (only a minor efficiency issue)
378    
379     * src/gigdump.cpp:
380     - added printout of samples' looping informations
381    
382 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
383    
384     * initial release
