* src/DLS.cpp:
  - further bugfixes regarding DLS write support
* src/dlsdump.cpp:
  - show for every region the name of the referenced sample
  - show file name in quotation marks

1 Version CVS HEAD (?)
2
3 * general changes:
4 - added write support (only to the RIFF and DLS 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 * src/DLS.cpp, src/DLS.h:
13 - fixed loading of Articulation Connections (<artl> list chunks were
14 seeked instead of ordinary <artl> data chunks)
15 - added write support (highly experimental)
16
17 * src/RIFF.cpp, src/RIFF.h:
18 - added write support
19 - Chunk::LoadChunkData() can now be called again to resize the buffer
20 after a Chunk::Resize() and before the File::Save() call to allow
21 placing the new data in the chunk's write buffer and perform the
22 resize and write operations in one rush
23
24 * src/dlsdump.cpp:
25 - show for every region the name of the referenced sample
26 - show file name in quotation marks
27
28 Version 2.0.2 (15 Aug 2005)
29
30 * packaging changes:
31 - require automake (>= 1.5) for 'make -f Makefile.cvs'
32 (mandatory for 'dist-bzip2' automake option)
33
34 * src/gig.cpp, src/gig.h:
35 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
36 the extension files are read automatically when the samples are
37 loaded
38 - fixed the 24 bit decompression, the result should now be exact
39 instead of an approximation
40 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
41 function to DimensionRegion
42
43 * src/DLS.cpp, src/DLS.h:
44 - the upper bits of the pool table indices are read (used as
45 extension file numbers for gig v3)
46
47 * src/RIFF.cpp, src/RIFF.h:
48 - the file name is remembered in the RIFF::File object
49
50 Version 2.0.1 (12 Jun 2005)
51
52 * packaging changes:
53 - include debian/ directory on 'make dist'
54 - create a bzip2 tarball on 'make dist'
55
56 * src/gigextract.cpp:
57 - show also version of libsndfile or build version of libaudiofile when
58 using the -v switch
59 - fixed mutual link dependency to libsndfile / libaudiofile
60
61 * src/gig.cpp, src/gig.h:
62 - added DimensionRegion::GetVelocityRelease function
63
64 Version 2.0.0 (9 May 2005)
65
66 * packaging changes:
67 - fixed conditional linkage of either libsndfile or libaudiofile
68 (if none of the two exist, configure script will abort)
69 - man pages are now auto generated with the correct libgig version
70
71 * src/gig.cpp, src/gig.h:
72 - experimental support for Gigasampler v3 format;
73 64 bit file offsets are truncated to 32 bit, 24 bit samples are
74 truncated to 16 bit, up to 8 dimensions are read, additional
75 articulation informations are ignored at the moment
76 (patch by Andreas Persson)
77 - added some file format compatibility checks
78 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
79 never used, because the necessary check was made before
80 initialization)
81 - fixed crossfade points order (structure for big endian and little
82 endian systems was interchanged)
83 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
84 - fixed crash which occured when patches did not have a sample assigned
85 to their region or dimension region (patch by Andreas Persson)
86 - support for compressed mono samples
87 - experimental support for compressed 24 bit samples
88 - fixed decompression on big-endian CPUs
89 - fixed decompression bug that truncated the last block of samples
90 - external decompression buffers can now be used for streaming samples
91 to avoid race conditions in case of multiple streaming threads
92 - added pre-calculated sample attenuation parameter
93 - added v3 "random" and "round robin" dimensions
94 - implemented progress indicator callback mechanism for loading
95 instruments and samples
96 - added functions libraryName() and libraryVersion()
97
98 * src/DLS.cpp, src/DLS.h:
99 - fixed File constructor which caused variable File::Instruments always
100 to be zero
101 - added functions libraryName() and libraryVersion()
102
103 * src/RIFF.cpp, src/RIFF.h:
104 - fixed method List::LoadSubChunks() which did not restore the original
105 position within the body of the given list chunk
106 - added functions libraryName() and libraryVersion()
107
108 * src/rifftree.cpp:
109 - added command line switch -v to show rifftree's revision and the used
110 libgig version
111
112 * src/dlsdump.cpp:
113 - added command line switch -v to show dlsdump's revision and the used
114 libgig version
115
116 * src/gigdump.cpp:
117 - added output of UnityNote, FineTune, Gain, SampleStartOffset an
118 LoopPlayCount
119 - added command line switch -v to show gigdump's revision and the used

125 used libgig version
126
127 Version 1.0.0 (26 Nov 2004)
128
129 * packaging changes:
130 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
131 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
132 - fixed man pages automake install rule (which didn't work on Mandrake,
133 SuSE and Fedora)
134 - fixed generation of Doxygen API documentation (now also included in
135 RPM and Debian packages)
136
137 * src/gig.cpp, src/gig.h:
138 - fixed / improved accuracy of all three velocity to volume
139 transformation functions a.k.a. 'nonlinear','linear','special'
140 (patch by Andreas Persson)
141 - denormals are filtered from the velocity to volume tables
142 - bugfix for dimension region switching (wrong handling of the release
143 trigger dimension, no bit range check for dimensions of split type
144 'split_type_bit')
145 - fixed panorama value in DimensionRegion (invalid conversion from
146 signed 7 bit to signed 8 bit)
147 - added class attribute 'Layers' to class 'gig::Region'
148 - symbol prototyping of gig::Region (fixes build failure with qsampler)
149
150 * src/gigextract.cpp:
151 - added support for libsndfile (if libaudiofile and libsndfile are
152 available then libsndfile is preferred)
153
154 * src/gigdump.cpp:
155 - added printout for dimension informations (amount, type, bits, zones)
156 - added printout for velocity response curve parameters
157 - added printout for crossfade definitions
158 - added printout for panorama value for each DimensionRegion
159 - replaced printout of DLS Region layer by printout of amount of
160 Gigasampler layers
161
162 Version 0.7.1 (2 Jul 2004)
163
164 * packaging changes:
165 - added libgig.spec and libgig.pc package configurations for generating
166 Redhat packages
167 - header files included on installation.
168 - autotools-generated files removed from CVS repository.
169 - added support for generating Debian packages
170 - version of shared library can be set in configure.in
171
172 Version 0.7.0 (3 May 2004)
173
174 * general changes:
175 - various big endian specific corrections
176 (successfully tested now on PPC)
177 - minor adjustments to avoid compile errors on some systems
178 (using now pow() instead of powl() and --pedantic g++ compiler switch)
179 - libtoolized the library
180 - added man pages for the command line tools
181 (gigextract, gigdump, dlsdump, rifftree)
182
183 * src/gig.cpp, src/gig.h:
184 - fixed bug in decompression algorithm which caused it not to detect
185 the end of a stream
186 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
187 takes the MIDI key velocity value as an argument and returns the
188 appropriate volume factor (0.0 ... 1.0) for the sample to be played
189 back, the velocity curve transformation functions used for this are
190 only an approximation so far
191 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
192 'Sample::LoopSize' which reflected wrong values
193 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
194 measured in sample points instead of byte offset
195 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
196 'Sample::FineTune'
197 - added class attribute 'Sample::LoopSize'
198 - added method GetInstrument(uint index) to class 'File'
199 - added ReadAndLoop() method to class 'Sample' which is an extension to
200 the normal Read() method to honor the sample's looping information
201 while streaming from disk
202 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
203 'eg2_ctrl_t': replaced this huge enumeration by a structure which
204 reflects the MIDI controller number in case of an ordinary control
205 change controller (this saves a huge switch-case block in the
206 application of the library user)
207 - renamed following attributes in class 'DimensionRegion':
208 'AttenuationContol' -> 'AttenuationController',
209 'InvertAttenuationControl' -> 'InvertAttenuationController',
210 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
211 - minor fix in API documentation for method GetVelocityAttenuation() in
212 class 'DimensionRegion'
213
214 * src/RIFF.cpp, src/RIFF.h:
215 - added additional API documentation
216 - minor fix in Chunk::Read() method (only a minor efficiency issue)
217
218 * src/gigdump.cpp:
219 - added printout of samples' looping informations
220
221 Version 0.6.0 (3 Nov 2003)
222
223 * initial release
