* several fixes for the write support

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

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

151 position within the body of the given list chunk
152 - added functions libraryName() and libraryVersion()
153
154 * src/rifftree.cpp:

156 libgig version
157
158 * src/dlsdump.cpp:
159 - added command line switch -v to show dlsdump's revision and the used
160 libgig version
161

173 Version 1.0.0 (26 Nov 2004)
174
175 * packaging changes:
176 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
177 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
178 - fixed man pages automake install rule (which didn't work on Mandrake,
179 SuSE and Fedora)
180 - fixed generation of Doxygen API documentation (now also included in
181 RPM and Debian packages)
182
183 * src/gig.cpp, src/gig.h:
184 - fixed / improved accuracy of all three velocity to volume
185 transformation functions a.k.a. 'nonlinear','linear','special'
186 (patch by Andreas Persson)
187 - denormals are filtered from the velocity to volume tables
188 - bugfix for dimension region switching (wrong handling of the release
189 trigger dimension, no bit range check for dimensions of split type
190 'split_type_bit')
191 - fixed panorama value in DimensionRegion (invalid conversion from
192 signed 7 bit to signed 8 bit)
193 - added class attribute 'Layers' to class 'gig::Region'
194 - symbol prototyping of gig::Region (fixes build failure with qsampler)
195
196 * src/gigextract.cpp:
197 - added support for libsndfile (if libaudiofile and libsndfile are
198 available then libsndfile is preferred)
199
200 * src/gigdump.cpp:
201 - added printout for dimension informations (amount, type, bits, zones)
202 - added printout for velocity response curve parameters
203 - added printout for crossfade definitions
204 - added printout for panorama value for each DimensionRegion
205 - replaced printout of DLS Region layer by printout of amount of
206 Gigasampler layers
207
208 Version 0.7.1 (2 Jul 2004)
209
210 * packaging changes:
211 - added libgig.spec and libgig.pc package configurations for generating
212 Redhat packages
213 - header files included on installation.
214 - autotools-generated files removed from CVS repository.
215 - added support for generating Debian packages
216 - version of shared library can be set in configure.in
217
218 Version 0.7.0 (3 May 2004)
219
220 * general changes:
221 - various big endian specific corrections
222 (successfully tested now on PPC)
223 - minor adjustments to avoid compile errors on some systems
224 (using now pow() instead of powl() and --pedantic g++ compiler switch)
225 - libtoolized the library
226 - added man pages for the command line tools
227 (gigextract, gigdump, dlsdump, rifftree)
228
229 * src/gig.cpp, src/gig.h:
230 - fixed bug in decompression algorithm which caused it not to detect
231 the end of a stream
232 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
233 takes the MIDI key velocity value as an argument and returns the
234 appropriate volume factor (0.0 ... 1.0) for the sample to be played
235 back, the velocity curve transformation functions used for this are
236 only an approximation so far
237 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
238 'Sample::LoopSize' which reflected wrong values
239 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
240 measured in sample points instead of byte offset
241 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
242 'Sample::FineTune'
243 - added class attribute 'Sample::LoopSize'
244 - added method GetInstrument(uint index) to class 'File'
245 - added ReadAndLoop() method to class 'Sample' which is an extension to
246 the normal Read() method to honor the sample's looping information
247 while streaming from disk
248 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
249 'eg2_ctrl_t': replaced this huge enumeration by a structure which
250 reflects the MIDI controller number in case of an ordinary control
251 change controller (this saves a huge switch-case block in the
252 application of the library user)
253 - renamed following attributes in class 'DimensionRegion':
254 'AttenuationContol' -> 'AttenuationController',
255 'InvertAttenuationControl' -> 'InvertAttenuationController',
256 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
257 - minor fix in API documentation for method GetVelocityAttenuation() in
258 class 'DimensionRegion'
259
260 * src/RIFF.cpp, src/RIFF.h:
261 - added additional API documentation
262 - minor fix in Chunk::Read() method (only a minor efficiency issue)
263
264 * src/gigdump.cpp:
265 - added printout of samples' looping informations
266
267 Version 0.6.0 (3 Nov 2003)
268
269 * initial release
