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 persson 1301 - AddDimension now copies all parameters from existing dimension
55     regions and also makes sure that the samplechannel dimension is
56     placed first in the list of dimensions.
57 schoenebeck 1158

64    
65 schoenebeck 1116 Version 3.1.1 (24 Mar 2007)
66 schoenebeck 1050
67     * packaging changes:
68     - ported to Windows using native Windows functions for file IO
69     (provided Dev-C++ + mingw project file)
70 schoenebeck 1079 - only export relevant files to Doxygen API documentation
71 schoenebeck 1050
72 persson 1070 * src/gig.cpp, src/gig.h:

75     velocity (gig v3 feature)
76 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
77 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
78     group but moves all its members to another group, the other method,
79     that is File::DeleteGroup() now removes not just the group, but also
80     all the samples that belong to that group
81 schoenebeck 1083 - fixed crash which occured on interfering File::DeleteSample() and
82     File::GetNextSample() calls (due to iterator invalidation)

93     dimension definition fields
94 persson 1070

100 schoenebeck 1095 * src/RIFF.cpp, src/RIFF.h:
101     - fixed RIFF::Chunk destructor which did not unregister previously

231 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

301 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
302 schoenebeck 231
303 schoenebeck 220 * src/gigextract.cpp:
304     - added support for libsndfile (if libaudiofile and libsndfile are

315 capela 168 Version 0.7.1 (2 Jul 2004)
316    
317     * packaging changes:
318 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
319     Redhat packages

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