File size: 12675 byte(s)
* added MoveRegion and MoveSubChunk
* fixed initialization in AddRegion

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 - only export relevant files to Doxygen API documentation
7
8 * src/gig.cpp, src/gig.h:
9 - custom velocity splits now works for gig v3 files too
10 - added support for custom splits points for other dimensions than
11 velocity (gig v3 feature)
12 - added "smart midi" and "round robin keyboard" dimensions
13 - added new method File::DeleteGroupOnly() which only deletes the given
14 group but moves all its members to another group, the other method,
15 that is File::DeleteGroup() now removes not just the group, but also
16 all the samples that belong to that group
17 - fixed crash which occured on interfering File::DeleteSample() and
18 File::GetNextSample() calls (due to iterator invalidation)
19 - fixed group names which were not saved
20 - fixed group destructor which did not remove the RIFF chunk associated
21 with the group
22 - added Instrument::MoveRegion method
23 - fixed constructor for Region, which did not initialize correctly
24 when used from Instrument::AddRegion
25
26 * src/DLS.cpp, src/DLS.h:
27 - added Instrument::MoveRegion method
28
29 * src/RIFF.cpp, src/RIFF.h:
30 - fixed RIFF::Chunk destructor which did not unregister previously
31 resized chunks, leading to a "zero size chunk" exception when
32 File::Save() was called
33 - added List::MoveSubChunk method
34
35 Version 3.1.0 (24 Nov 2006)
36
37 * packaging changes:
38 - changed deprecated copyright attribute to license;
39 added ldconfig to post-(un)install steps on libgig.spec (RPM)
40
41 * src/gig.cpp, src/gig.h:
42 - added support for more than one set of custom velocity splits
43 inside a region (for example different velocity split levels for
44 pedal up and pedal down)
45 - sample loop parameters are now taken from the DimensionRegion
46 instead of the wave chunk
47 - keyswitching dimension is changed from split type "normal" to
48 "bit"
49 - real support for 24 bit samples - samples are not truncated to
50 16 bits anymore
51 - support for reading of ".art" files. (Merging of .art and .gig
52 files are not implemented yet.)
53 - several fixes for the write support
54 - support for sample groups added
55
56 * src/DLS.cpp, src/DLS.h:

63 - real support for 24 bit samples
64
65 * src/gigdump.cpp:
66 - print global file informations
67 - print sample groups
68
69 * general changes:
70 - added CPPUnit test cases (at the moment primarily for automatic check
71 of Gigasampler write support)
72
73 Version 3.0.0 (28 Apr 2006)
74
75 * general changes:
76 - added write support (that is for creating and modifying RIFF, DLS and
77 gig files)
78 - loading DLS and gig files is now much more permissive, DLS and gig
79 files are now loaded even if mandatory RIFF chunks are missing
80 - fixed some memory management errors, one of them was causing a
81 crash when a multi-file gig was deallocated
82
83 * src/gig.cpp, src/gig.h:
84 - fixed the GetVelocityCutoff function, it wasn't always using the
85 VCFVelocityScale parameter when no cutoff controller was defined
86 - support for the gig v3 feature to have a number of dimension
87 splits not equal to a power of two
88 - added write support (highly experimental)
89
90 * src/DLS.cpp, src/DLS.h:
91 - fixed loading of Articulation Connections (<artl> list chunks were
92 seeked instead of ordinary <artl> data chunks)
93 - added write support (highly experimental)
94
95 * src/RIFF.cpp, src/RIFF.h:
96 - added write support
97 - Chunk::LoadChunkData() can now be called again to resize the buffer
98 after a Chunk::Resize() and before the File::Save() call to allow
99 placing the new data in the chunk's write buffer and perform the
100 resize and write operations in one rush
101
102 * src/gigdump.cpp:
103 - fixed to show the correct amount of dimension regions instead of 32
104 (patch by James Wylder)
105
106 * src/dlsdump.cpp:
107 - show for every region the name of the referenced sample

114 (mandatory for 'dist-bzip2' automake option)
115
116 * src/gig.cpp, src/gig.h:
117 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
118 the extension files are read automatically when the samples are
119 loaded
120 - fixed the 24 bit decompression, the result should now be exact
121 instead of an approximation
122 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
123 function to DimensionRegion
124
125 * src/DLS.cpp, src/DLS.h:

150 (if none of the two exist, configure script will abort)
151 - man pages are now auto generated with the correct libgig version
152
153 * src/gig.cpp, src/gig.h:
154 - experimental support for Gigasampler v3 format;
155 64 bit file offsets are truncated to 32 bit, 24 bit samples are
156 truncated to 16 bit, up to 8 dimensions are read, additional
157 articulation informations are ignored at the moment
158 (patch by Andreas Persson)
159 - added some file format compatibility checks
160 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
161 never used, because the necessary check was made before

210
211 * packaging changes:
212 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
213 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
214 - fixed man pages automake install rule (which didn't work on Mandrake,
215 SuSE and Fedora)
216 - fixed generation of Doxygen API documentation (now also included in
217 RPM and Debian packages)
218
219 * src/gig.cpp, src/gig.h:
220 - fixed / improved accuracy of all three velocity to volume
221 transformation functions a.k.a. 'nonlinear','linear','special'
222 (patch by Andreas Persson)
223 - denormals are filtered from the velocity to volume tables
224 - bugfix for dimension region switching (wrong handling of the release
225 trigger dimension, no bit range check for dimensions of split type
226 'split_type_bit')

228 signed 7 bit to signed 8 bit)
229 - added class attribute 'Layers' to class 'gig::Region'
230 - symbol prototyping of gig::Region (fixes build failure with qsampler)
231

242 Gigasampler layers
243
244 Version 0.7.1 (2 Jul 2004)
245
246 * packaging changes:
247 - added libgig.spec and libgig.pc package configurations for generating
248 Redhat packages
249 - header files included on installation.
250 - autotools-generated files removed from CVS repository.
251 - added support for generating Debian packages
252 - version of shared library can be set in configure.in
253
254 Version 0.7.0 (3 May 2004)
255
256 * general changes:
257 - various big endian specific corrections
258 (successfully tested now on PPC)
259 - minor adjustments to avoid compile errors on some systems
260 (using now pow() instead of powl() and --pedantic g++ compiler switch)
261 - libtoolized the library
262 - added man pages for the command line tools
263 (gigextract, gigdump, dlsdump, rifftree)
264
265 * src/gig.cpp, src/gig.h:
266 - fixed bug in decompression algorithm which caused it not to detect
267 the end of a stream
268 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
269 takes the MIDI key velocity value as an argument and returns the
270 appropriate volume factor (0.0 ... 1.0) for the sample to be played
271 back, the velocity curve transformation functions used for this are
272 only an approximation so far
273 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
274 'Sample::LoopSize' which reflected wrong values
275 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
276 measured in sample points instead of byte offset
277 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
278 'Sample::FineTune'
279 - added class attribute 'Sample::LoopSize'
280 - added method GetInstrument(uint index) to class 'File'
281 - added ReadAndLoop() method to class 'Sample' which is an extension to
282 the normal Read() method to honor the sample's looping information
283 while streaming from disk
284 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
285 'eg2_ctrl_t': replaced this huge enumeration by a structure which
286 reflects the MIDI controller number in case of an ordinary control
287 change controller (this saves a huge switch-case block in the
288 application of the library user)
289 - renamed following attributes in class 'DimensionRegion':
290 'AttenuationContol' -> 'AttenuationController',
291 'InvertAttenuationControl' -> 'InvertAttenuationController',
292 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
293 - minor fix in API documentation for method GetVelocityAttenuation() in
294 class 'DimensionRegion'
295
296 * src/RIFF.cpp, src/RIFF.h:
297 - added additional API documentation
298 - minor fix in Chunk::Read() method (only a minor efficiency issue)
299
300 * src/gigdump.cpp:
301 - added printout of samples' looping informations
302
303 Version 0.6.0 (3 Nov 2003)
304
305 * initial release
