* added "smart midi" and "round robin keyboard" dimensions

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - ported to Windows using native Windows functions for file IO
5 (provided Dev-C++ + mingw project file)
6
7 * src/gig.cpp, src/gig.h:
8 - custom velocity splits now works for gig v3 files too
9 - added support for custom splits points for other dimensions than
10 velocity (gig v3 feature)
11 - added "smart midi" and "round robin keyboard" dimensions
12
13 Version 3.1.0 (24 Nov 2006)
14
15 * packaging changes:
16 - changed deprecated copyright attribute to license;
17 added ldconfig to post-(un)install steps on libgig.spec (RPM)
18
19 * src/gig.cpp, src/gig.h:
20 - added support for more than one set of custom velocity splits
21 inside a region (for example different velocity split levels for
22 pedal up and pedal down)
23 - sample loop parameters are now taken from the DimensionRegion
24 instead of the wave chunk
25 - keyswitching dimension is changed from split type "normal" to
26 "bit"
27 - real support for 24 bit samples - samples are not truncated to
28 16 bits anymore
29 - support for reading of ".art" files. (Merging of .art and .gig
30 files are not implemented yet.)
31 - several fixes for the write support
32 - support for sample groups added
33
34 * src/DLS.cpp, src/DLS.h:

41 - real support for 24 bit samples
42
43 * src/gigdump.cpp:
44 - print global file informations
45 - print sample groups
46
47 * general changes:
48 - added CPPUnit test cases (at the moment primarily for automatic check
49 of Gigasampler write support)
50
51 Version 3.0.0 (28 Apr 2006)
52
53 * general changes:
54 - added write support (that is for creating and modifying RIFF, DLS and
55 gig files)
56 - loading DLS and gig files is now much more permissive, DLS and gig
57 files are now loaded even if mandatory RIFF chunks are missing
58 - fixed some memory management errors, one of them was causing a
59 crash when a multi-file gig was deallocated
60
61 * src/gig.cpp, src/gig.h:
62 - fixed the GetVelocityCutoff function, it wasn't always using the
63 VCFVelocityScale parameter when no cutoff controller was defined
64 - support for the gig v3 feature to have a number of dimension
65 splits not equal to a power of two
66 - added write support (highly experimental)
67
68 * src/DLS.cpp, src/DLS.h:
69 - fixed loading of Articulation Connections (<artl> list chunks were
70 seeked instead of ordinary <artl> data chunks)
71 - added write support (highly experimental)
72
73 * src/RIFF.cpp, src/RIFF.h:
74 - added write support
75 - Chunk::LoadChunkData() can now be called again to resize the buffer
76 after a Chunk::Resize() and before the File::Save() call to allow
77 placing the new data in the chunk's write buffer and perform the
78 resize and write operations in one rush
79
80 * src/gigdump.cpp:
81 - fixed to show the correct amount of dimension regions instead of 32
82 (patch by James Wylder)
83
84 * src/dlsdump.cpp:
85 - show for every region the name of the referenced sample
86 - show file name in quotation marks
87
88 Version 2.0.2 (15 Aug 2005)
89
90 * packaging changes:
91 - require automake (>= 1.5) for 'make -f Makefile.cvs'
92 (mandatory for 'dist-bzip2' automake option)
93
94 * src/gig.cpp, src/gig.h:
95 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
96 the extension files are read automatically when the samples are
97 loaded
98 - fixed the 24 bit decompression, the result should now be exact
99 instead of an approximation
100 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
101 function to DimensionRegion
102
103 * src/DLS.cpp, src/DLS.h:
104 - the upper bits of the pool table indices are read (used as
105 extension file numbers for gig v3)
106
107 * src/RIFF.cpp, src/RIFF.h:
108 - the file name is remembered in the RIFF::File object
109

128 (if none of the two exist, configure script will abort)
129 - man pages are now auto generated with the correct libgig version
130
131 * src/gig.cpp, src/gig.h:
132 - experimental support for Gigasampler v3 format;
133 64 bit file offsets are truncated to 32 bit, 24 bit samples are
134 truncated to 16 bit, up to 8 dimensions are read, additional
135 articulation informations are ignored at the moment
136 (patch by Andreas Persson)
137 - added some file format compatibility checks
138 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
139 never used, because the necessary check was made before

142 endian systems was interchanged)
143 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

187 Version 1.0.0 (26 Nov 2004)
188
189 * packaging changes:
190 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
191 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
192 - fixed man pages automake install rule (which didn't work on Mandrake,
193 SuSE and Fedora)
194 - fixed generation of Doxygen API documentation (now also included in
195 RPM and Debian packages)
196
197 * src/gig.cpp, src/gig.h:
198 - fixed / improved accuracy of all three velocity to volume
199 transformation functions a.k.a. 'nonlinear','linear','special'
200 (patch by Andreas Persson)
201 - denormals are filtered from the velocity to volume tables
202 - bugfix for dimension region switching (wrong handling of the release
203 trigger dimension, no bit range check for dimensions of split type
204 'split_type_bit')
205 - fixed panorama value in DimensionRegion (invalid conversion from
206 signed 7 bit to signed 8 bit)
207 - added class attribute 'Layers' to class 'gig::Region'
208 - symbol prototyping of gig::Region (fixes build failure with qsampler)
209
210 * src/gigextract.cpp:
211 - added support for libsndfile (if libaudiofile and libsndfile are
212 available then libsndfile is preferred)
213
214 * src/gigdump.cpp:
215 - added printout for dimension informations (amount, type, bits, zones)
216 - added printout for velocity response curve parameters
217 - added printout for crossfade definitions
218 - added printout for panorama value for each DimensionRegion
219 - replaced printout of DLS Region layer by printout of amount of
220 Gigasampler layers
221
222 Version 0.7.1 (2 Jul 2004)
223
224 * packaging changes:
225 - added libgig.spec and libgig.pc package configurations for generating
226 Redhat packages
227 - header files included on installation.
228 - autotools-generated files removed from CVS repository.
229 - added support for generating Debian packages
230 - version of shared library can be set in configure.in
231
232 Version 0.7.0 (3 May 2004)
233
234 * general changes:
235 - various big endian specific corrections
236 (successfully tested now on PPC)
237 - minor adjustments to avoid compile errors on some systems
238 (using now pow() instead of powl() and --pedantic g++ compiler switch)
239 - libtoolized the library
240 - added man pages for the command line tools
241 (gigextract, gigdump, dlsdump, rifftree)
242
243 * src/gig.cpp, src/gig.h:
244 - fixed bug in decompression algorithm which caused it not to detect
245 the end of a stream
246 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
247 takes the MIDI key velocity value as an argument and returns the
248 appropriate volume factor (0.0 ... 1.0) for the sample to be played
249 back, the velocity curve transformation functions used for this are
250 only an approximation so far
251 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
252 'Sample::LoopSize' which reflected wrong values
253 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
254 measured in sample points instead of byte offset
255 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
256 'Sample::FineTune'
257 - added class attribute 'Sample::LoopSize'
258 - added method GetInstrument(uint index) to class 'File'
259 - added ReadAndLoop() method to class 'Sample' which is an extension to
260 the normal Read() method to honor the sample's looping information
261 while streaming from disk
262 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
263 'eg2_ctrl_t': replaced this huge enumeration by a structure which
264 reflects the MIDI controller number in case of an ordinary control
265 change controller (this saves a huge switch-case block in the
266 application of the library user)
267 - renamed following attributes in class 'DimensionRegion':
268 'AttenuationContol' -> 'AttenuationController',
269 'InvertAttenuationControl' -> 'InvertAttenuationController',
270 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
271 - minor fix in API documentation for method GetVelocityAttenuation() in
272 class 'DimensionRegion'
273
274 * src/RIFF.cpp, src/RIFF.h:
275 - added additional API documentation
276 - minor fix in Chunk::Read() method (only a minor efficiency issue)
277
278 * src/gigdump.cpp:
279 - added printout of samples' looping informations
280
281 Version 0.6.0 (3 Nov 2003)
282
283 * initial release
