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
12 Version 3.1.0 (24 Nov 2006)
13
14 * packaging changes:
15 - changed deprecated copyright attribute to license;
16 added ldconfig to post-(un)install steps on libgig.spec (RPM)
17
18 * src/gig.cpp, src/gig.h:
19 - added support for more than one set of custom velocity splits
20 inside a region (for example different velocity split levels for
21 pedal up and pedal down)
22 - sample loop parameters are now taken from the DimensionRegion
23 instead of the wave chunk
24 - keyswitching dimension is changed from split type "normal" to
25 "bit"
26 - real support for 24 bit samples - samples are not truncated to
27 16 bits anymore
28 - support for reading of ".art" files. (Merging of .art and .gig
29 files are not implemented yet.)
30 - several fixes for the write support
31 - support for sample groups added
32
33 * src/DLS.cpp, src/DLS.h:
34 - support for reading of ".art" files

38
39 * src/gigextract.cpp:
40 - real support for 24 bit samples
41
42 * src/gigdump.cpp:
43 - print global file informations
44 - print sample groups
45
46 * general changes:
47 - added CPPUnit test cases (at the moment primarily for automatic check
48 of Gigasampler write support)
49
50 Version 3.0.0 (28 Apr 2006)
51
52 * general changes:
53 - added write support (that is for creating and modifying RIFF, DLS and
54 gig files)
55 - loading DLS and gig files is now much more permissive, DLS and gig
56 files are now loaded even if mandatory RIFF chunks are missing
57 - fixed some memory management errors, one of them was causing a
58 crash when a multi-file gig was deallocated
59
60 * src/gig.cpp, src/gig.h:
61 - fixed the GetVelocityCutoff function, it wasn't always using the
62 VCFVelocityScale parameter when no cutoff controller was defined
63 - support for the gig v3 feature to have a number of dimension
64 splits not equal to a power of two
65 - added write support (highly experimental)
66
67 * src/DLS.cpp, src/DLS.h:
68 - fixed loading of Articulation Connections (<artl> list chunks were
69 seeked instead of ordinary <artl> data chunks)
70 - added write support (highly experimental)
71
72 * src/RIFF.cpp, src/RIFF.h:
73 - added write support
74 - Chunk::LoadChunkData() can now be called again to resize the buffer
75 after a Chunk::Resize() and before the File::Save() call to allow
76 placing the new data in the chunk's write buffer and perform the
77 resize and write operations in one rush
78
79 * src/gigdump.cpp:
80 - fixed to show the correct amount of dimension regions instead of 32
81 (patch by James Wylder)
82
83 * src/dlsdump.cpp:
84 - show for every region the name of the referenced sample
85 - show file name in quotation marks
86

88
89 * packaging changes:
90 - require automake (>= 1.5) for 'make -f Makefile.cvs'
91 (mandatory for 'dist-bzip2' automake option)
92
93 * src/gig.cpp, src/gig.h:
94 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
95 the extension files are read automatically when the samples are
96 loaded
97 - fixed the 24 bit decompression, the result should now be exact
98 instead of an approximation
99 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
100 function to DimensionRegion
101
102 * src/DLS.cpp, src/DLS.h:
103 - the upper bits of the pool table indices are read (used as
104 extension file numbers for gig v3)
105
106 * src/RIFF.cpp, src/RIFF.h:
107 - the file name is remembered in the RIFF::File object
108

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

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