* more write support fixes: crossfade parameters were not saved, v3
  dimension limits were not correctly initialized and saved when
  dimensions were added or deleted, v3 wave pool offsets were not
  saved correctly

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 schoenebeck 1158
47 persson 1183 * src/RIFF.cpp, src/RIFF.h:
48 persson 1184 - added File::SetByteOrder method
49 persson 1183
50 schoenebeck 1116 Version 3.1.1 (24 Mar 2007)

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

83     causing an exception when trying to save a new instrument
84 persson 1102
85 schoenebeck 1095 * src/RIFF.cpp, src/RIFF.h:
86     - fixed RIFF::Chunk destructor which did not unregister previously
87     resized chunks, leading to a "zero size chunk" exception when
88     File::Save() was called
89 persson 1102 - added List::MoveSubChunk method

102     instead of the wave chunk
103     - keyswitching dimension is changed from split type "normal" to
104     "bit"

156     resize and write operations in one rush
157    
158 schoenebeck 809 * src/gigdump.cpp:

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

266 schoenebeck 196
267     * packaging changes:
268     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

300 capela 168 Version 0.7.1 (2 Jul 2004)
301    
302     * packaging changes:
303 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
304     Redhat packages

306     - autotools-generated files removed from CVS repository.
307 schoenebeck 186 - added support for generating Debian packages
308     - version of shared library can be set in configure.in
309    
310 schoenebeck 58 Version 0.7.0 (3 May 2004)
311    
312     * general changes:
313     - various big endian specific corrections
314     (successfully tested now on PPC)
315     - minor adjustments to avoid compile errors on some systems
316     (using now pow() instead of powl() and --pedantic g++ compiler switch)
317     - libtoolized the library
318     - added man pages for the command line tools
319     (gigextract, gigdump, dlsdump, rifftree)
320    
321     * src/gig.cpp, src/gig.h:
322     - fixed bug in decompression algorithm which caused it not to detect
323     the end of a stream
324     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
325     takes the MIDI key velocity value as an argument and returns the
326     appropriate volume factor (0.0 ... 1.0) for the sample to be played
327     back, the velocity curve transformation functions used for this are
328     only an approximation so far
329     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
330     'Sample::LoopSize' which reflected wrong values
331     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
332     measured in sample points instead of byte offset
333     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
334     'Sample::FineTune'
335     - added class attribute 'Sample::LoopSize'
336     - added method GetInstrument(uint index) to class 'File'
337     - added ReadAndLoop() method to class 'Sample' which is an extension to
338     the normal Read() method to honor the sample's looping information
339     while streaming from disk
340     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
341     'eg2_ctrl_t': replaced this huge enumeration by a structure which
342     reflects the MIDI controller number in case of an ordinary control
343     change controller (this saves a huge switch-case block in the
344     application of the library user)
345     - renamed following attributes in class 'DimensionRegion':
346     'AttenuationContol' -> 'AttenuationController',
347     'InvertAttenuationControl' -> 'InvertAttenuationController',
348     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
349     - minor fix in API documentation for method GetVelocityAttenuation() in
350     class 'DimensionRegion'
351    
352     * src/RIFF.cpp, src/RIFF.h:
353     - added additional API documentation
354     - minor fix in Chunk::Read() method (only a minor efficiency issue)
355    
356     * src/gigdump.cpp:
357     - added printout of samples' looping informations
358    
359 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
360    
361     * initial release
