* support for Gigasampler's sample groups added

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 - several fixes for the write support
20 - support for sample groups added
21
22 * src/DLS.cpp, src/DLS.h:
23 - support for reading of ".art" files
24 - removed incorrect use of memccpy in the write support (patch by
25 Jeremy Kerr)
26 - several fixes for the write support
27
28 * src/gigextract.cpp:
29 - real support for 24 bit samples
30
31 * src/gigdump.cpp:
32 - print global file informations
33 - print sample groups
34
35 * general changes:
36 - added CPPUnit test cases (at the moment primarily for automatic check
37 of Gigasampler write support)
38
39 Version 3.0.0 (28 Apr 2006)
40
41 * general changes:
42 - added write support (that is for creating and modifying RIFF, DLS and
43 gig files)
44 - loading DLS and gig files is now much more permissive, DLS and gig
45 files are now loaded even if mandatory RIFF chunks are missing
46 - fixed some memory management errors, one of them was causing a
47 crash when a multi-file gig was deallocated
48
49 * src/gig.cpp, src/gig.h:
50 - fixed the GetVelocityCutoff function, it wasn't always using the
51 VCFVelocityScale parameter when no cutoff controller was defined
52 - support for the gig v3 feature to have a number of dimension
53 splits not equal to a power of two
54 - added write support (highly experimental)
55
56 * src/DLS.cpp, src/DLS.h:
57 - fixed loading of Articulation Connections (<artl> list chunks were
58 seeked instead of ordinary <artl> data chunks)
59 - added write support (highly experimental)
60
61 * src/RIFF.cpp, src/RIFF.h:
62 - added write support
63 - Chunk::LoadChunkData() can now be called again to resize the buffer
64 after a Chunk::Resize() and before the File::Save() call to allow
65 placing the new data in the chunk's write buffer and perform the
66 resize and write operations in one rush
67
68 * src/gigdump.cpp:
69 - fixed to show the correct amount of dimension regions instead of 32
70 (patch by James Wylder)
71
72 * src/dlsdump.cpp:
73 - show for every region the name of the referenced sample
74 - show file name in quotation marks
75
76 Version 2.0.2 (15 Aug 2005)
77
78 * packaging changes:
79 - require automake (>= 1.5) for 'make -f Makefile.cvs'
80 (mandatory for 'dist-bzip2' automake option)
81
82 * src/gig.cpp, src/gig.h:
83 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
84 the extension files are read automatically when the samples are
85 loaded
86 - fixed the 24 bit decompression, the result should now be exact
87 instead of an approximation
88 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
89 function to DimensionRegion
90
91 * src/DLS.cpp, src/DLS.h:
92 - the upper bits of the pool table indices are read (used as
93 extension file numbers for gig v3)
94
95 * src/RIFF.cpp, src/RIFF.h:
96 - the file name is remembered in the RIFF::File object
97
98 Version 2.0.1 (12 Jun 2005)
99
100 * packaging changes:
101 - include debian/ directory on 'make dist'
102 - create a bzip2 tarball on 'make dist'
103
104 * src/gigextract.cpp:
105 - show also version of libsndfile or build version of libaudiofile when
106 using the -v switch
107 - fixed mutual link dependency to libsndfile / libaudiofile

110 - added DimensionRegion::GetVelocityRelease function
111
112 Version 2.0.0 (9 May 2005)
113
114 * packaging changes:
115 - fixed conditional linkage of either libsndfile or libaudiofile
116 (if none of the two exist, configure script will abort)
117 - man pages are now auto generated with the correct libgig version
118
119 * src/gig.cpp, src/gig.h:
120 - experimental support for Gigasampler v3 format;
121 64 bit file offsets are truncated to 32 bit, 24 bit samples are
122 truncated to 16 bit, up to 8 dimensions are read, additional
123 articulation informations are ignored at the moment
124 (patch by Andreas Persson)
125 - added some file format compatibility checks
126 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
127 never used, because the necessary check was made before
128 initialization)
129 - fixed crossfade points order (structure for big endian and little
130 endian systems was interchanged)
131 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

133 to their region or dimension region (patch by Andreas Persson)
134 - support for compressed mono samples
135 - experimental support for compressed 24 bit samples
136 - fixed decompression on big-endian CPUs
137 - fixed decompression bug that truncated the last block of samples

153 position within the body of the given list chunk
154 - added functions libraryName() and libraryVersion()
155

176
177 * packaging changes:
178 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
179 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
180 - fixed man pages automake install rule (which didn't work on Mandrake,
181 SuSE and Fedora)
182 - fixed generation of Doxygen API documentation (now also included in
183 RPM and Debian packages)
184
185 * src/gig.cpp, src/gig.h:
186 - fixed / improved accuracy of all three velocity to volume
187 transformation functions a.k.a. 'nonlinear','linear','special'
188 (patch by Andreas Persson)
189 - denormals are filtered from the velocity to volume tables
190 - bugfix for dimension region switching (wrong handling of the release
191 trigger dimension, no bit range check for dimensions of split type
192 'split_type_bit')
193 - fixed panorama value in DimensionRegion (invalid conversion from
194 signed 7 bit to signed 8 bit)
195 - added class attribute 'Layers' to class 'gig::Region'
196 - symbol prototyping of gig::Region (fixes build failure with qsampler)
197
198 * src/gigextract.cpp:

200 available then libsndfile is preferred)
201
202 * src/gigdump.cpp:

205 - added printout for crossfade definitions
206 - added printout for panorama value for each DimensionRegion
207 - replaced printout of DLS Region layer by printout of amount of
208 Gigasampler layers
209
210 Version 0.7.1 (2 Jul 2004)
211
212 * packaging changes:
213 - added libgig.spec and libgig.pc package configurations for generating
214 Redhat packages
215 - header files included on installation.
216 - autotools-generated files removed from CVS repository.
217 - added support for generating Debian packages
218 - version of shared library can be set in configure.in
219
220 Version 0.7.0 (3 May 2004)
221
222 * general changes:
223 - various big endian specific corrections
224 (successfully tested now on PPC)
225 - minor adjustments to avoid compile errors on some systems
226 (using now pow() instead of powl() and --pedantic g++ compiler switch)
227 - libtoolized the library
228 - added man pages for the command line tools
229 (gigextract, gigdump, dlsdump, rifftree)
230
231 * src/gig.cpp, src/gig.h:
232 - fixed bug in decompression algorithm which caused it not to detect
233 the end of a stream
234 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
235 takes the MIDI key velocity value as an argument and returns the
236 appropriate volume factor (0.0 ... 1.0) for the sample to be played
237 back, the velocity curve transformation functions used for this are
238 only an approximation so far
239 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
240 'Sample::LoopSize' which reflected wrong values
241 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
242 measured in sample points instead of byte offset
243 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
244 'Sample::FineTune'
245 - added class attribute 'Sample::LoopSize'
246 - added method GetInstrument(uint index) to class 'File'
247 - added ReadAndLoop() method to class 'Sample' which is an extension to
248 the normal Read() method to honor the sample's looping information
249 while streaming from disk
250 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
251 'eg2_ctrl_t': replaced this huge enumeration by a structure which
252 reflects the MIDI controller number in case of an ordinary control
253 change controller (this saves a huge switch-case block in the
254 application of the library user)
255 - renamed following attributes in class 'DimensionRegion':
256 'AttenuationContol' -> 'AttenuationController',
257 'InvertAttenuationControl' -> 'InvertAttenuationController',
258 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
259 - minor fix in API documentation for method GetVelocityAttenuation() in
260 class 'DimensionRegion'
261
262 * src/RIFF.cpp, src/RIFF.h:
263 - added additional API documentation
264 - minor fix in Chunk::Read() method (only a minor efficiency issue)
265
266 * src/gigdump.cpp:
267 - added printout of samples' looping informations
268
269 Version 0.6.0 (3 Nov 2003)
270
271 * initial release
