* real support for 24 bit samples
* support for reading of .art files

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

139 - fixed method List::LoadSubChunks() which did not restore the original
140 position within the body of the given list chunk
141 - added functions libraryName() and libraryVersion()
142
143 * src/rifftree.cpp:
144 - added command line switch -v to show rifftree's revision and the used
145 libgig version
146
147 * src/dlsdump.cpp:
148 - added command line switch -v to show dlsdump's revision and the used
149 libgig version

161
162 Version 1.0.0 (26 Nov 2004)
163
164 * packaging changes:
165 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
166 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
167 - fixed man pages automake install rule (which didn't work on Mandrake,
168 SuSE and Fedora)
169 - fixed generation of Doxygen API documentation (now also included in
170 RPM and Debian packages)
171
172 * src/gig.cpp, src/gig.h:
173 - fixed / improved accuracy of all three velocity to volume
174 transformation functions a.k.a. 'nonlinear','linear','special'
175 (patch by Andreas Persson)
176 - denormals are filtered from the velocity to volume tables
177 - bugfix for dimension region switching (wrong handling of the release
178 trigger dimension, no bit range check for dimensions of split type
179 'split_type_bit')
180 - fixed panorama value in DimensionRegion (invalid conversion from
181 signed 7 bit to signed 8 bit)
182 - added class attribute 'Layers' to class 'gig::Region'
183 - symbol prototyping of gig::Region (fixes build failure with qsampler)
184
185 * src/gigextract.cpp:
186 - added support for libsndfile (if libaudiofile and libsndfile are
187 available then libsndfile is preferred)
188
189 * src/gigdump.cpp:
190 - added printout for dimension informations (amount, type, bits, zones)
191 - added printout for velocity response curve parameters
192 - added printout for crossfade definitions
193 - added printout for panorama value for each DimensionRegion
194 - replaced printout of DLS Region layer by printout of amount of
195 Gigasampler layers
196
197 Version 0.7.1 (2 Jul 2004)
198
199 * packaging changes:
200 - added libgig.spec and libgig.pc package configurations for generating
201 Redhat packages
202 - header files included on installation.
203 - autotools-generated files removed from CVS repository.
204 - added support for generating Debian packages
205 - version of shared library can be set in configure.in
206
207 Version 0.7.0 (3 May 2004)
208
209 * general changes:
210 - various big endian specific corrections
211 (successfully tested now on PPC)
212 - minor adjustments to avoid compile errors on some systems
213 (using now pow() instead of powl() and --pedantic g++ compiler switch)
214 - libtoolized the library
215 - added man pages for the command line tools
216 (gigextract, gigdump, dlsdump, rifftree)
217
218 * src/gig.cpp, src/gig.h:
219 - fixed bug in decompression algorithm which caused it not to detect
220 the end of a stream
221 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
222 takes the MIDI key velocity value as an argument and returns the
223 appropriate volume factor (0.0 ... 1.0) for the sample to be played
224 back, the velocity curve transformation functions used for this are
225 only an approximation so far
226 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
227 'Sample::LoopSize' which reflected wrong values
228 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
229 measured in sample points instead of byte offset
230 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
231 'Sample::FineTune'
232 - added class attribute 'Sample::LoopSize'
233 - added method GetInstrument(uint index) to class 'File'
234 - added ReadAndLoop() method to class 'Sample' which is an extension to
235 the normal Read() method to honor the sample's looping information
236 while streaming from disk
237 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
238 'eg2_ctrl_t': replaced this huge enumeration by a structure which
239 reflects the MIDI controller number in case of an ordinary control
240 change controller (this saves a huge switch-case block in the
241 application of the library user)
242 - renamed following attributes in class 'DimensionRegion':
243 'AttenuationContol' -> 'AttenuationController',
244 'InvertAttenuationControl' -> 'InvertAttenuationController',
245 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
246 - minor fix in API documentation for method GetVelocityAttenuation() in
247 class 'DimensionRegion'
248
249 * src/RIFF.cpp, src/RIFF.h:
250 - added additional API documentation
251 - minor fix in Chunk::Read() method (only a minor efficiency issue)
252
253 * src/gigdump.cpp:
254 - added printout of samples' looping informations
255
256 Version 0.6.0 (3 Nov 2003)
257
258 * initial release
