* support for the gig v3 feature to have a number of dimension splits
  not equal to a power of two

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