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 persson 1266 - write support fix: allow regions without mapped samples
15 schoenebeck 1154
16 schoenebeck 1158 * src/gig.cpp, src/gig.h:
17     - fixed segmentation fault in the gig::File destructor sequence which
18     happened when gig::Group informations were accessed before
19 persson 1179 - fixed write support for big-endian systems
20 persson 1180 - defined lengths of a fixed set of info strings. These strings
21     are saved when the file is written, even if they are empty.
22 persson 1182 - added missing parameter initalizations in sample, region and
23     instrument constructors
24     - clear unused fields when saving samples and regions
25     - fixed write support bugs: v3 dimension limits and chunksize
26     weren't saved, leverage controller of type controlchange
27 persson 1195 couldn't be saved, group name list chunk was placed wrong,
28     dimension region chunks also placed wrong
29 persson 1182 - added initialization of some fixed info strings in file and
30     instrument
31 persson 1192 - write support: files created by libgig will now have the RIFF
32     chunks in correct order
33 persson 1199 - write support: two previously unknown fields in dimension
34     definition are now saved
35     - added constants for gig file versions
36     - write support: the 3crc and einf chunks are now created or
37     updated when a file is saved (3crc contains sample checksums,
38     einf contains file statistics)
39 persson 1209 - write support: DLSID is now generated on the file and the
40     instruments
41 persson 1218 - write support: improved the default values for dimension region
42     parameters
43 persson 1247 - more write support fixes: crossfade parameters were not saved,
44     v3 dimension limits were not correctly initialized and saved
45     when dimensions were added or deleted, v3 wave pool offsets were
46     not saved correctly
47 persson 1264 - write support: 24 bit samples can now be written
48     - write support: version 3 is now the default for new files
49 persson 1266 - more write support fixes: the 3ewg chunk is now bigger for v3,
50     dimension regions without mapped samples are now allowed, 3gnl
51     list in v3 files now always has 128 entries, several parameters
52     where incorrectly saved due to an operator precedence mistake
53     - DeleteSample now removes all references to the deleted sample
54 schoenebeck 1158
55 persson 1183 * src/RIFF.cpp, src/RIFF.h:
56 persson 1184 - added File::SetByteOrder method

62 schoenebeck 1050
63     * packaging changes:
64     - ported to Windows using native Windows functions for file IO
65     (provided Dev-C++ + mingw project file)
66 schoenebeck 1079 - only export relevant files to Doxygen API documentation
67 schoenebeck 1050
68 persson 1070 * src/gig.cpp, src/gig.h:
69     - custom velocity splits now works for gig v3 files too
70     - added support for custom splits points for other dimensions than
71     velocity (gig v3 feature)
72 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
73 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
74     group but moves all its members to another group, the other method,
75     that is File::DeleteGroup() now removes not just the group, but also
76     all the samples that belong to that group
77 schoenebeck 1083 - fixed crash which occured on interfering File::DeleteSample() and
78     File::GetNextSample() calls (due to iterator invalidation)
79 schoenebeck 1098 - fixed group names which were not saved
80 schoenebeck 1099 - fixed group destructor which did not remove the RIFF chunk associated
81     with the group
82 persson 1102 - added Instrument::MoveRegion method
83     - fixed constructor for Region, which did not initialize correctly
84     when used from Instrument::AddRegion
85 schoenebeck 1106 - when saving, override the gig::Regions sample reference simply by
86     the region's first dimension region's sample (avoids an exception
87     when trying to save a new instrument)

89     dimension definition fields
90 persson 1070

95 persson 1102
96 schoenebeck 1095 * src/RIFF.cpp, src/RIFF.h:
97     - fixed RIFF::Chunk destructor which did not unregister previously
98     resized chunks, leading to a "zero size chunk" exception when
99     File::Save() was called
100 persson 1102 - added List::MoveSubChunk method
101 schoenebeck 1095

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

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

302    
303 schoenebeck 229 * src/gigdump.cpp:

311 capela 168 Version 0.7.1 (2 Jul 2004)
312    
313     * packaging changes:

318 schoenebeck 186 - added support for generating Debian packages
319     - version of shared library can be set in configure.in
320    
321 schoenebeck 58 Version 0.7.0 (3 May 2004)
322    
323     * general changes:
324     - various big endian specific corrections
325     (successfully tested now on PPC)
326     - minor adjustments to avoid compile errors on some systems
327     (using now pow() instead of powl() and --pedantic g++ compiler switch)
328     - libtoolized the library
329     - added man pages for the command line tools
330     (gigextract, gigdump, dlsdump, rifftree)
331    
332     * src/gig.cpp, src/gig.h:
333     - fixed bug in decompression algorithm which caused it not to detect
334     the end of a stream
335     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
336     takes the MIDI key velocity value as an argument and returns the
337     appropriate volume factor (0.0 ... 1.0) for the sample to be played
338     back, the velocity curve transformation functions used for this are
339     only an approximation so far
340     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
341     'Sample::LoopSize' which reflected wrong values
342     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
343     measured in sample points instead of byte offset
344     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
345     'Sample::FineTune'
346     - added class attribute 'Sample::LoopSize'
347     - added method GetInstrument(uint index) to class 'File'
348     - added ReadAndLoop() method to class 'Sample' which is an extension to
349     the normal Read() method to honor the sample's looping information
350     while streaming from disk
351     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
352     'eg2_ctrl_t': replaced this huge enumeration by a structure which
353     reflects the MIDI controller number in case of an ordinary control
354     change controller (this saves a huge switch-case block in the
355     application of the library user)
356     - renamed following attributes in class 'DimensionRegion':
357     'AttenuationContol' -> 'AttenuationController',
358     'InvertAttenuationControl' -> 'InvertAttenuationController',
359     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
360     - minor fix in API documentation for method GetVelocityAttenuation() in
361     class 'DimensionRegion'
362    
363     * src/RIFF.cpp, src/RIFF.h:
364     - added additional API documentation
365     - minor fix in Chunk::Read() method (only a minor efficiency issue)
366    
367     * src/gigdump.cpp:
368     - added printout of samples' looping informations
369    
370 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
371    
372     * initial release
