Revision 515 - (show annotations) (download)
Sat May 7 20:19:10 2005 UTC (14 years, 9 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 Version CVS HEAD (?)
2
3 * packaging changes:
4 - fixed conditional linkage of either libsndfile or libaudiofile
5 (if none of the two exist, configure script will abort)
6
7 * 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 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 - added some file format compatibility checks
14 - 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 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
20 - fixed crash which occured when patches did not have a sample assigned
21 to their region or dimension region (patch by Andreas Persson)
22 - 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 - external decompression buffers can now be used for streaming samples
27 to avoid race conditions in case of multiple streaming threads
28 - added pre-calculated sample attenuation parameter
29 - added v3 "random" and "round robin" dimensions
30 - implemented progress indicator callback mechanism for loading
31 instruments and samples
32
33 * 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 * src/gigdump.cpp:
42 - added output of UnityNote and FineTune
43 - added output of Gain and SampleStartOffset
44 - added output of LoopPlayCount
45
46 * src/gigextract.cpp:
47 - support for compressed mono samples and compressed 24 bit samples
48
49 Version 1.0.0 (26 Nov 2004)
50
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 - 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
59 * src/gig.cpp, src/gig.h:
60 - fixed / improved accuracy of all three velocity to volume
61 transformation functions a.k.a. 'nonlinear','linear','special'
62 (patch by Andreas Persson)
63 - denormals are filtered from the velocity to volume tables
64 - 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 - fixed panorama value in DimensionRegion (invalid conversion from
68 signed 7 bit to signed 8 bit)
69 - added class attribute 'Layers' to class 'gig::Region'
70 - symbol prototyping of gig::Region (fixes build failure with qsampler)
71
72 * src/gigextract.cpp:
73 - added support for libsndfile (if libaudiofile and libsndfile are
74 available then libsndfile is preferred)
75
76 * src/gigdump.cpp:
77 - added printout for dimension informations (amount, type, bits, zones)
78 - added printout for velocity response curve parameters
79 - added printout for crossfade definitions
80 - added printout for panorama value for each DimensionRegion
81 - replaced printout of DLS Region layer by printout of amount of
82 Gigasampler layers
83
84 Version 0.7.1 (2 Jul 2004)
85
86 * packaging changes:
87 - added libgig.spec and libgig.pc package configurations for generating
88 Redhat packages
89 - header files included on installation.
90 - autotools-generated files removed from CVS repository.
91 - added support for generating Debian packages
92 - version of shared library can be set in configure.in
93
94 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 Version 0.6.0 (3 Nov 2003)
144
145 * initial release
