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 persson 1247 - more write support fixes: crossfade parameters were not saved,
43     v3 dimension limits were not correctly initialized and saved
44     when dimensions were added or deleted, v3 wave pool offsets were
45     not saved correctly
46 persson 1264 - write support: 24 bit samples can now be written
47     - write support: version 3 is now the default for new files
48     - more write support fixes: the 3ewg chunk is now bigger for v3
49 schoenebeck 1158
50 persson 1183 * src/RIFF.cpp, src/RIFF.h:

57 schoenebeck 1050
58     * packaging changes:
59     - ported to Windows using native Windows functions for file IO
60     (provided Dev-C++ + mingw project file)
61 schoenebeck 1079 - only export relevant files to Doxygen API documentation
62 schoenebeck 1050
63 persson 1070 * src/gig.cpp, src/gig.h:
64     - custom velocity splits now works for gig v3 files too
65     - added support for custom splits points for other dimensions than
66     velocity (gig v3 feature)
67 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
68 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
69     group but moves all its members to another group, the other method,
70     that is File::DeleteGroup() now removes not just the group, but also
71     all the samples that belong to that group
72 schoenebeck 1083 - fixed crash which occured on interfering File::DeleteSample() and
73     File::GetNextSample() calls (due to iterator invalidation)
74 schoenebeck 1098 - fixed group names which were not saved

76     with the group
77 persson 1102 - added Instrument::MoveRegion method
78     - fixed constructor for Region, which did not initialize correctly
79     when used from Instrument::AddRegion
80 schoenebeck 1106 - when saving, override the gig::Regions sample reference simply by
81     the region's first dimension region's sample (avoids an exception
82     when trying to save a new instrument)
83 schoenebeck 1113 - fixed AddDimension() method which did not fill out all mandatory
84     dimension definition fields
85 persson 1070

94     File::Save() was called
95 persson 1102 - added List::MoveSubChunk method
96 schoenebeck 1095

108     instead of the wave chunk
109     - keyswitching dimension is changed from split type "normal" to
110     "bit"
111 persson 902 - real support for 24 bit samples - samples are not truncated to

162     resize and write operations in one rush
163    
164 schoenebeck 809 * src/gigdump.cpp:

220     (patch by Andreas Persson)
221 schoenebeck 317 - added some file format compatibility checks
222 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
223     never used, because the necessary check was made before

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

306 capela 168 Version 0.7.1 (2 Jul 2004)
307    
308     * packaging changes:
309 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating

313 schoenebeck 186 - added support for generating Debian packages
314     - version of shared library can be set in configure.in
315    
316 schoenebeck 58 Version 0.7.0 (3 May 2004)
317    
318     * general changes:
319     - various big endian specific corrections
320     (successfully tested now on PPC)
321     - minor adjustments to avoid compile errors on some systems
322     (using now pow() instead of powl() and --pedantic g++ compiler switch)
323     - libtoolized the library
324     - added man pages for the command line tools
325     (gigextract, gigdump, dlsdump, rifftree)
326    
327     * src/gig.cpp, src/gig.h:
328     - fixed bug in decompression algorithm which caused it not to detect
329     the end of a stream
330     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
331     takes the MIDI key velocity value as an argument and returns the
332     appropriate volume factor (0.0 ... 1.0) for the sample to be played
333     back, the velocity curve transformation functions used for this are
334     only an approximation so far
335     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
336     'Sample::LoopSize' which reflected wrong values
337     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
338     measured in sample points instead of byte offset
339     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
340     'Sample::FineTune'
341     - added class attribute 'Sample::LoopSize'
342     - added method GetInstrument(uint index) to class 'File'
343     - added ReadAndLoop() method to class 'Sample' which is an extension to
344     the normal Read() method to honor the sample's looping information
345     while streaming from disk
346     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
347     'eg2_ctrl_t': replaced this huge enumeration by a structure which
348     reflects the MIDI controller number in case of an ordinary control
349     change controller (this saves a huge switch-case block in the
350     application of the library user)
351     - renamed following attributes in class 'DimensionRegion':
352     'AttenuationContol' -> 'AttenuationController',
353     'InvertAttenuationControl' -> 'InvertAttenuationController',
354     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
355     - minor fix in API documentation for method GetVelocityAttenuation() in
356     class 'DimensionRegion'
357    
358     * src/RIFF.cpp, src/RIFF.h:
359     - added additional API documentation
360     - minor fix in Chunk::Read() method (only a minor efficiency issue)
361    
362     * src/gigdump.cpp:
363     - added printout of samples' looping informations
364    
365 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
366    
367     * initial release
