* added VCFCutoffControllerInvert parameter and GetVelocityCutoff
  function to DimensionRegion

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