Sat May 7 20:19:10 2005 UTC (18 years, 10 months ago) by schoenebeck
File size: 6496 byte(s)
* src/gig.h, src/gig.cpp: implemented progress indicator callback mechanism
  for loading instruments and samples
* src/DLS.cpp: fixed File constructor which caused variable
  File::Instruments always to be zero
* src/RIFF.cpp: fixed method List::LoadSubChunks() which did not restore
  the original position within the body of the given list chunk

1 schoenebeck 317 Version CVS HEAD (?)
2    
3 schoenebeck 383 * packaging changes:
4     - fixed conditional linkage of either libsndfile or libaudiofile
5     (if none of the two exist, configure script will abort)
6    
7 schoenebeck 317 * src/gig.cpp, src/gig.h:
8     - experimental support for Gigasampler v3 format;
9     64 bit file offsets are truncated to 32 bit, 24 bit samples are
10 schoenebeck 347 truncated to 16 bit, up to 8 dimensions are read, additional
11     articulation informations are ignored at the moment
12     (patch by Andreas Persson)
13 schoenebeck 317 - added some file format compatibility checks
14 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
15     never used, because the necessary check was made before
16     initialization)
17     - fixed crossfade points order (structure for big endian and little
18     endian systems was interchanged)
19 schoenebeck 355 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
20 schoenebeck 352 - fixed crash which occured when patches did not have a sample assigned
21     to their region or dimension region (patch by Andreas Persson)
22 persson 365 - support for compressed mono samples
23     - experimental support for compressed 24 bit samples
24     - fixed decompression on big-endian CPUs
25     - fixed decompression bug that truncated the last block of samples
26 schoenebeck 384 - external decompression buffers can now be used for streaming samples
27     to avoid race conditions in case of multiple streaming threads
28 persson 406 - added pre-calculated sample attenuation parameter
29 persson 437 - added v3 "random" and "round robin" dimensions
30 schoenebeck 515 - implemented progress indicator callback mechanism for loading
31     instruments and samples
32 schoenebeck 317
33 schoenebeck 515 * src/DLS.cpp:
34     - fixed File constructor which caused variable File::Instruments always
35     to be zero
36    
37     * src/RIFF.cpp:
38     - fixed method List::LoadSubChunks() which did not restore the original
39     position within the body of the given list chunk
40    
41 schoenebeck 334 * src/gigdump.cpp:
42     - added output of UnityNote and FineTune
43 persson 406 - added output of Gain and SampleStartOffset
44 schoenebeck 511 - added output of LoopPlayCount
45 schoenebeck 334
46 persson 365 * src/gigextract.cpp:
47     - support for compressed mono samples and compressed 24 bit samples
48    
49 schoenebeck 315 Version 1.0.0 (26 Nov 2004)
50 schoenebeck 196
51     * packaging changes:
52     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
53     'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
54 schoenebeck 315 - fixed man pages automake install rule (which didn't work on Mandrake,
55     SuSE and Fedora)
56     - fixed generation of Doxygen API documentation (now also included in
57     RPM and Debian packages)
58 schoenebeck 196
59 schoenebeck 231 * src/gig.cpp, src/gig.h:
60     - fixed / improved accuracy of all three velocity to volume
61 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
62     (patch by Andreas Persson)
63 schoenebeck 231 - denormals are filtered from the velocity to volume tables
64 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
65     trigger dimension, no bit range check for dimensions of split type
66     'split_type_bit')
67 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
68     signed 7 bit to signed 8 bit)
69 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
70 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
71 schoenebeck 231
72 schoenebeck 220 * src/gigextract.cpp:
73     - added support for libsndfile (if libaudiofile and libsndfile are
74     available then libsndfile is preferred)
75    
76 schoenebeck 229 * src/gigdump.cpp:
77     - added printout for dimension informations (amount, type, bits, zones)
78 schoenebeck 231 - added printout for velocity response curve parameters
79 schoenebeck 235 - added printout for crossfade definitions
80 schoenebeck 269 - added printout for panorama value for each DimensionRegion
81 schoenebeck 282 - replaced printout of DLS Region layer by printout of amount of
82     Gigasampler layers
83 schoenebeck 229
84 capela 168 Version 0.7.1 (2 Jul 2004)
85    
86     * packaging changes:
87 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
88     Redhat packages
89 capela 168 - header files included on installation.
90     - autotools-generated files removed from CVS repository.
91 schoenebeck 186 - added support for generating Debian packages
92     - version of shared library can be set in configure.in
93    
94 schoenebeck 58 Version 0.7.0 (3 May 2004)
95    
96     * general changes:
97     - various big endian specific corrections
98     (successfully tested now on PPC)
99     - minor adjustments to avoid compile errors on some systems
100     (using now pow() instead of powl() and --pedantic g++ compiler switch)
101     - libtoolized the library
102     - added man pages for the command line tools
103     (gigextract, gigdump, dlsdump, rifftree)
104    
105     * src/gig.cpp, src/gig.h:
106     - fixed bug in decompression algorithm which caused it not to detect
107     the end of a stream
108     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
109     takes the MIDI key velocity value as an argument and returns the
110     appropriate volume factor (0.0 ... 1.0) for the sample to be played
111     back, the velocity curve transformation functions used for this are
112     only an approximation so far
113     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
114     'Sample::LoopSize' which reflected wrong values
115     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
116     measured in sample points instead of byte offset
117     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
118     'Sample::FineTune'
119     - added class attribute 'Sample::LoopSize'
120     - added method GetInstrument(uint index) to class 'File'
121     - added ReadAndLoop() method to class 'Sample' which is an extension to
122     the normal Read() method to honor the sample's looping information
123     while streaming from disk
124     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
125     'eg2_ctrl_t': replaced this huge enumeration by a structure which
126     reflects the MIDI controller number in case of an ordinary control
127     change controller (this saves a huge switch-case block in the
128     application of the library user)
129     - renamed following attributes in class 'DimensionRegion':
130     'AttenuationContol' -> 'AttenuationController',
131     'InvertAttenuationControl' -> 'InvertAttenuationController',
132     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
133     - minor fix in API documentation for method GetVelocityAttenuation() in
134     class 'DimensionRegion'
135    
136     * src/RIFF.cpp, src/RIFF.h:
137     - added additional API documentation
138     - minor fix in Chunk::Read() method (only a minor efficiency issue)
139    
140     * src/gigdump.cpp:
141     - added printout of samples' looping informations
142    
143 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
144    
145     * initial release
