* added write support (only to the RIFF classes yet)

1 Version CVS HEAD (?)
2
3 * general changes:
4 - added write support (only to the RIFF classes yet)
5
6 * src/gig.cpp, src/gig.h:
7 - fixed the GetVelocityCutoff function, it wasn't always using the
8 VCFVelocityScale parameter when no cutoff controller was defined
9 - support for the gig v3 feature to have a number of dimension
10 splits not equal to a power of two
11
12 Version 2.0.2 (15 Aug 2005)
13
14 * packaging changes:
15 - require automake (>= 1.5) for 'make -f Makefile.cvs'
16 (mandatory for 'dist-bzip2' automake option)
17
18 * src/gig.cpp, src/gig.h:
19 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
20 the extension files are read automatically when the samples are
21 loaded
22 - fixed the 24 bit decompression, the result should now be exact
23 instead of an approximation
24 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
25 function to DimensionRegion
26
27 * src/DLS.cpp, src/DLS.h:
28 - the upper bits of the pool table indices are read (used as
29 extension file numbers for gig v3)
30
31 * src/RIFF.cpp, src/RIFF.h:
32 - the file name is remembered in the RIFF::File object
33
34 Version 2.0.1 (12 Jun 2005)
35
36 * packaging changes:
37 - include debian/ directory on 'make dist'
38 - create a bzip2 tarball on 'make dist'
39
40 * src/gigextract.cpp:
41 - show also version of libsndfile or build version of libaudiofile when
42 using the -v switch
43 - fixed mutual link dependency to libsndfile / libaudiofile
44
45 * src/gig.cpp, src/gig.h:
46 - added DimensionRegion::GetVelocityRelease function
47
48 Version 2.0.0 (9 May 2005)
49
50 * packaging changes:
51 - fixed conditional linkage of either libsndfile or libaudiofile
52 (if none of the two exist, configure script will abort)
53 - man pages are now auto generated with the correct libgig version
54
55 * src/gig.cpp, src/gig.h:
56 - experimental support for Gigasampler v3 format;
57 64 bit file offsets are truncated to 32 bit, 24 bit samples are
58 truncated to 16 bit, up to 8 dimensions are read, additional
59 articulation informations are ignored at the moment
60 (patch by Andreas Persson)
61 - added some file format compatibility checks
62 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
63 never used, because the necessary check was made before
64 initialization)
65 - fixed crossfade points order (structure for big endian and little
66 endian systems was interchanged)
67 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
68 - fixed crash which occured when patches did not have a sample assigned
69 to their region or dimension region (patch by Andreas Persson)
70 - support for compressed mono samples
71 - experimental support for compressed 24 bit samples
72 - fixed decompression on big-endian CPUs
73 - fixed decompression bug that truncated the last block of samples
74 - external decompression buffers can now be used for streaming samples
75 to avoid race conditions in case of multiple streaming threads
76 - added pre-calculated sample attenuation parameter
77 - added v3 "random" and "round robin" dimensions
78 - implemented progress indicator callback mechanism for loading
79 instruments and samples
80 - added functions libraryName() and libraryVersion()
81
82 * src/DLS.cpp, src/DLS.h:
83 - fixed File constructor which caused variable File::Instruments always
84 to be zero
85 - added functions libraryName() and libraryVersion()
86
87 * src/RIFF.cpp, src/RIFF.h:
88 - fixed method List::LoadSubChunks() which did not restore the original
89 position within the body of the given list chunk
90 - added functions libraryName() and libraryVersion()
91
92 * src/rifftree.cpp:
93 - added command line switch -v to show rifftree's revision and the used
94 libgig version
95
96 * src/dlsdump.cpp:
97 - added command line switch -v to show dlsdump's revision and the used
98 libgig version
99
100 * src/gigdump.cpp:
101 - added output of UnityNote, FineTune, Gain, SampleStartOffset an
102 LoopPlayCount
103 - added command line switch -v to show gigdump's revision and the used
104 libgig version
105
106 * src/gigextract.cpp:
107 - support for compressed mono samples and compressed 24 bit samples
108 - added command line switch -v to show gigextract's revision and the
109 used libgig version
110
111 Version 1.0.0 (26 Nov 2004)
112
113 * packaging changes:
114 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
115 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
116 - fixed man pages automake install rule (which didn't work on Mandrake,
117 SuSE and Fedora)
118 - fixed generation of Doxygen API documentation (now also included in
119 RPM and Debian packages)
120
121 * src/gig.cpp, src/gig.h:
122 - fixed / improved accuracy of all three velocity to volume
123 transformation functions a.k.a. 'nonlinear','linear','special'
124 (patch by Andreas Persson)
125 - denormals are filtered from the velocity to volume tables
126 - bugfix for dimension region switching (wrong handling of the release
127 trigger dimension, no bit range check for dimensions of split type
128 'split_type_bit')
129 - fixed panorama value in DimensionRegion (invalid conversion from
130 signed 7 bit to signed 8 bit)
131 - added class attribute 'Layers' to class 'gig::Region'
132 - symbol prototyping of gig::Region (fixes build failure with qsampler)
133
134 * src/gigextract.cpp:
135 - added support for libsndfile (if libaudiofile and libsndfile are
136 available then libsndfile is preferred)
137
138 * src/gigdump.cpp:
139 - added printout for dimension informations (amount, type, bits, zones)
140 - added printout for velocity response curve parameters
141 - added printout for crossfade definitions
142 - added printout for panorama value for each DimensionRegion
143 - replaced printout of DLS Region layer by printout of amount of
144 Gigasampler layers
145
146 Version 0.7.1 (2 Jul 2004)
147
148 * packaging changes:
149 - added libgig.spec and libgig.pc package configurations for generating
150 Redhat packages
151 - header files included on installation.
152 - autotools-generated files removed from CVS repository.
153 - added support for generating Debian packages
154 - version of shared library can be set in configure.in
155
156 Version 0.7.0 (3 May 2004)
157
158 * general changes:
159 - various big endian specific corrections
160 (successfully tested now on PPC)
161 - minor adjustments to avoid compile errors on some systems
162 (using now pow() instead of powl() and --pedantic g++ compiler switch)
163 - libtoolized the library
164 - added man pages for the command line tools
165 (gigextract, gigdump, dlsdump, rifftree)
166
167 * src/gig.cpp, src/gig.h:
168 - fixed bug in decompression algorithm which caused it not to detect
169 the end of a stream
170 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
171 takes the MIDI key velocity value as an argument and returns the
172 appropriate volume factor (0.0 ... 1.0) for the sample to be played
173 back, the velocity curve transformation functions used for this are
174 only an approximation so far
175 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
176 'Sample::LoopSize' which reflected wrong values
177 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
178 measured in sample points instead of byte offset
179 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
180 'Sample::FineTune'
181 - added class attribute 'Sample::LoopSize'
182 - added method GetInstrument(uint index) to class 'File'
183 - added ReadAndLoop() method to class 'Sample' which is an extension to
184 the normal Read() method to honor the sample's looping information
185 while streaming from disk
186 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
187 'eg2_ctrl_t': replaced this huge enumeration by a structure which
188 reflects the MIDI controller number in case of an ordinary control
189 change controller (this saves a huge switch-case block in the
190 application of the library user)
191 - renamed following attributes in class 'DimensionRegion':
192 'AttenuationContol' -> 'AttenuationController',
193 'InvertAttenuationControl' -> 'InvertAttenuationController',
194 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
195 - minor fix in API documentation for method GetVelocityAttenuation() in
196 class 'DimensionRegion'
197
198 * src/RIFF.cpp, src/RIFF.h:
199 - added additional API documentation
200 - minor fix in Chunk::Read() method (only a minor efficiency issue)
201
202 * src/gigdump.cpp:
203 - added printout of samples' looping informations
204
205 Version 0.6.0 (3 Nov 2003)
206
207 * initial release
