* added support for more than one custom velocity split inside a
  region

1 Version CVS HEAD (?)
2
3 * src/gig.cpp, src/gig.h:
4 - added support for more than one set of custom velocity splits
5 inside a region (for example different velocity split levels for
6 pedal up and pedal down)
7
8 Version 3.0.0 (28 Apr 2006)
9
10 * general changes:
11 - added write support (that is for creating and modifying RIFF, DLS and
12 gig files)
13 - loading DLS and gig files is now much more permissive, DLS and gig
14 files are now loaded even if mandatory RIFF chunks are missing
15 - fixed some memory management errors, one of them was causing a
16 crash when a multi-file gig was deallocated
17
18 * src/gig.cpp, src/gig.h:
19 - fixed the GetVelocityCutoff function, it wasn't always using the
20 VCFVelocityScale parameter when no cutoff controller was defined
21 - support for the gig v3 feature to have a number of dimension
22 splits not equal to a power of two
23 - added write support (highly experimental)
24
25 * src/DLS.cpp, src/DLS.h:
26 - fixed loading of Articulation Connections (<artl> list chunks were
27 seeked instead of ordinary <artl> data chunks)
28 - added write support (highly experimental)
29
30 * src/RIFF.cpp, src/RIFF.h:
31 - added write support
32 - Chunk::LoadChunkData() can now be called again to resize the buffer
33 after a Chunk::Resize() and before the File::Save() call to allow
34 placing the new data in the chunk's write buffer and perform the
35 resize and write operations in one rush
36
37 * src/gigdump.cpp:
38 - fixed to show the correct amount of dimension regions instead of 32
39 (patch by James Wylder)
40
41 * src/dlsdump.cpp:
42 - show for every region the name of the referenced sample
43 - show file name in quotation marks
44
45 Version 2.0.2 (15 Aug 2005)
46
47 * packaging changes:
48 - require automake (>= 1.5) for 'make -f Makefile.cvs'
49 (mandatory for 'dist-bzip2' automake option)
50
51 * src/gig.cpp, src/gig.h:
52 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
53 the extension files are read automatically when the samples are
54 loaded
55 - fixed the 24 bit decompression, the result should now be exact
56 instead of an approximation
57 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
58 function to DimensionRegion
59
60 * src/DLS.cpp, src/DLS.h:
61 - the upper bits of the pool table indices are read (used as
62 extension file numbers for gig v3)
63
64 * src/RIFF.cpp, src/RIFF.h:
65 - the file name is remembered in the RIFF::File object
66
67 Version 2.0.1 (12 Jun 2005)
68
69 * packaging changes:
70 - include debian/ directory on 'make dist'
71 - create a bzip2 tarball on 'make dist'
72
73 * src/gigextract.cpp:
74 - show also version of libsndfile or build version of libaudiofile when
75 using the -v switch
76 - fixed mutual link dependency to libsndfile / libaudiofile
77
78 * src/gig.cpp, src/gig.h:
79 - added DimensionRegion::GetVelocityRelease function
80
81 Version 2.0.0 (9 May 2005)
82
83 * packaging changes:
84 - fixed conditional linkage of either libsndfile or libaudiofile
85 (if none of the two exist, configure script will abort)
86 - man pages are now auto generated with the correct libgig version
87
88 * src/gig.cpp, src/gig.h:
89 - experimental support for Gigasampler v3 format;
90 64 bit file offsets are truncated to 32 bit, 24 bit samples are
91 truncated to 16 bit, up to 8 dimensions are read, additional
92 articulation informations are ignored at the moment
93 (patch by Andreas Persson)
94 - added some file format compatibility checks
95 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
96 never used, because the necessary check was made before
97 initialization)
98 - fixed crossfade points order (structure for big endian and little
99 endian systems was interchanged)
100 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
101 - fixed crash which occured when patches did not have a sample assigned
102 to their region or dimension region (patch by Andreas Persson)
103 - support for compressed mono samples
104 - experimental support for compressed 24 bit samples
105 - fixed decompression on big-endian CPUs
106 - fixed decompression bug that truncated the last block of samples
107 - external decompression buffers can now be used for streaming samples
108 to avoid race conditions in case of multiple streaming threads
109 - added pre-calculated sample attenuation parameter
110 - added v3 "random" and "round robin" dimensions
111 - implemented progress indicator callback mechanism for loading
112 instruments and samples
113 - added functions libraryName() and libraryVersion()

117 to be zero
118 - added functions libraryName() and libraryVersion()
119
120 * src/RIFF.cpp, src/RIFF.h:
121 - fixed method List::LoadSubChunks() which did not restore the original
122 position within the body of the given list chunk
123 - added functions libraryName() and libraryVersion()
124
125 * src/rifftree.cpp:
126 - added command line switch -v to show rifftree's revision and the used
127 libgig version
128
129 * src/dlsdump.cpp:
130 - added command line switch -v to show dlsdump's revision and the used
131 libgig version
132
133 * src/gigdump.cpp:

142 used libgig version
143
144 Version 1.0.0 (26 Nov 2004)
145
146 * packaging changes:
147 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
148 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
149 - fixed man pages automake install rule (which didn't work on Mandrake,
150 SuSE and Fedora)
151 - fixed generation of Doxygen API documentation (now also included in
152 RPM and Debian packages)
153
154 * src/gig.cpp, src/gig.h:
155 - fixed / improved accuracy of all three velocity to volume
156 transformation functions a.k.a. 'nonlinear','linear','special'
157 (patch by Andreas Persson)
158 - denormals are filtered from the velocity to volume tables
159 - bugfix for dimension region switching (wrong handling of the release
160 trigger dimension, no bit range check for dimensions of split type
161 'split_type_bit')
162 - fixed panorama value in DimensionRegion (invalid conversion from
163 signed 7 bit to signed 8 bit)
164 - added class attribute 'Layers' to class 'gig::Region'
165 - symbol prototyping of gig::Region (fixes build failure with qsampler)
166
167 * src/gigextract.cpp:

169 available then libsndfile is preferred)
170
171 * src/gigdump.cpp:

173 - added printout for velocity response curve parameters
174 - added printout for crossfade definitions
175 - added printout for panorama value for each DimensionRegion
176 - replaced printout of DLS Region layer by printout of amount of
177 Gigasampler layers
178
179 Version 0.7.1 (2 Jul 2004)
180
181 * packaging changes:
182 - added libgig.spec and libgig.pc package configurations for generating
183 Redhat packages
184 - header files included on installation.
185 - autotools-generated files removed from CVS repository.
186 - added support for generating Debian packages
187 - version of shared library can be set in configure.in
188
189 Version 0.7.0 (3 May 2004)
190
191 * general changes:
192 - various big endian specific corrections
193 (successfully tested now on PPC)
194 - minor adjustments to avoid compile errors on some systems
195 (using now pow() instead of powl() and --pedantic g++ compiler switch)
196 - libtoolized the library
197 - added man pages for the command line tools
198 (gigextract, gigdump, dlsdump, rifftree)
199
200 * src/gig.cpp, src/gig.h:
201 - fixed bug in decompression algorithm which caused it not to detect
202 the end of a stream
203 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
204 takes the MIDI key velocity value as an argument and returns the
205 appropriate volume factor (0.0 ... 1.0) for the sample to be played
206 back, the velocity curve transformation functions used for this are
207 only an approximation so far
208 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
209 'Sample::LoopSize' which reflected wrong values
210 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
211 measured in sample points instead of byte offset
212 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
213 'Sample::FineTune'
214 - added class attribute 'Sample::LoopSize'
215 - added method GetInstrument(uint index) to class 'File'
216 - added ReadAndLoop() method to class 'Sample' which is an extension to
217 the normal Read() method to honor the sample's looping information
218 while streaming from disk
219 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
220 'eg2_ctrl_t': replaced this huge enumeration by a structure which
221 reflects the MIDI controller number in case of an ordinary control
222 change controller (this saves a huge switch-case block in the
223 application of the library user)
224 - renamed following attributes in class 'DimensionRegion':
225 'AttenuationContol' -> 'AttenuationController',
226 'InvertAttenuationControl' -> 'InvertAttenuationController',
227 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
228 - minor fix in API documentation for method GetVelocityAttenuation() in
229 class 'DimensionRegion'
230
231 * src/RIFF.cpp, src/RIFF.h:
232 - added additional API documentation
233 - minor fix in Chunk::Read() method (only a minor efficiency issue)
234
235 * src/gigdump.cpp:
236 - added printout of samples' looping informations
237
238 Version 0.6.0 (3 Nov 2003)
239
240 * initial release
