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
16 Version 3.0.0 (28 Apr 2006)
17
18 * general changes:
19 - added write support (that is for creating and modifying RIFF, DLS and
20 gig files)
21 - loading DLS and gig files is now much more permissive, DLS and gig
22 files are now loaded even if mandatory RIFF chunks are missing
23 - fixed some memory management errors, one of them was causing a
24 crash when a multi-file gig was deallocated
25
26 * src/gig.cpp, src/gig.h:
27 - fixed the GetVelocityCutoff function, it wasn't always using the
28 VCFVelocityScale parameter when no cutoff controller was defined
29 - support for the gig v3 feature to have a number of dimension
30 splits not equal to a power of two
31 - added write support (highly experimental)
32
33 * src/DLS.cpp, src/DLS.h:
34 - fixed loading of Articulation Connections (<artl> list chunks were
35 seeked instead of ordinary <artl> data chunks)
36 - added write support (highly experimental)
37
38 * src/RIFF.cpp, src/RIFF.h:
39 - added write support
40 - Chunk::LoadChunkData() can now be called again to resize the buffer
41 after a Chunk::Resize() and before the File::Save() call to allow
42 placing the new data in the chunk's write buffer and perform the
43 resize and write operations in one rush
44
45 * src/gigdump.cpp:
46 - fixed to show the correct amount of dimension regions instead of 32
47 (patch by James Wylder)
48
49 * src/dlsdump.cpp:
50 - show for every region the name of the referenced sample
51 - show file name in quotation marks
52
53 Version 2.0.2 (15 Aug 2005)
54
55 * packaging changes:
56 - require automake (>= 1.5) for 'make -f Makefile.cvs'
57 (mandatory for 'dist-bzip2' automake option)
58
59 * src/gig.cpp, src/gig.h:
60 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
61 the extension files are read automatically when the samples are
62 loaded
63 - fixed the 24 bit decompression, the result should now be exact
64 instead of an approximation
65 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
66 function to DimensionRegion
67
68 * src/DLS.cpp, src/DLS.h:
69 - the upper bits of the pool table indices are read (used as
70 extension file numbers for gig v3)
71
72 * src/RIFF.cpp, src/RIFF.h:
73 - the file name is remembered in the RIFF::File object
74
75 Version 2.0.1 (12 Jun 2005)

78 - include debian/ directory on 'make dist'
79 - create a bzip2 tarball on 'make dist'
80
81 * src/gigextract.cpp:
82 - show also version of libsndfile or build version of libaudiofile when
83 using the -v switch
84 - fixed mutual link dependency to libsndfile / libaudiofile

87 - added DimensionRegion::GetVelocityRelease function
88
89 Version 2.0.0 (9 May 2005)
90
91 * packaging changes:
92 - fixed conditional linkage of either libsndfile or libaudiofile
93 (if none of the two exist, configure script will abort)
94 - man pages are now auto generated with the correct libgig version
95
96 * src/gig.cpp, src/gig.h:
97 - experimental support for Gigasampler v3 format;
98 64 bit file offsets are truncated to 32 bit, 24 bit samples are
99 truncated to 16 bit, up to 8 dimensions are read, additional
100 articulation informations are ignored at the moment
101 (patch by Andreas Persson)
102 - added some file format compatibility checks
103 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
104 never used, because the necessary check was made before
105 initialization)
106 - fixed crossfade points order (structure for big endian and little
107 endian systems was interchanged)
108 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
109 - fixed crash which occured when patches did not have a sample assigned
110 to their region or dimension region (patch by Andreas Persson)
111 - support for compressed mono samples
112 - experimental support for compressed 24 bit samples
113 - fixed decompression on big-endian CPUs
114 - fixed decompression bug that truncated the last block of samples
115 - external decompression buffers can now be used for streaming samples
116 to avoid race conditions in case of multiple streaming threads

130 position within the body of the given list chunk
131 - added functions libraryName() and libraryVersion()
132
133 * src/rifftree.cpp:
134 - added command line switch -v to show rifftree's revision and the used
135 libgig version
136
137 * src/dlsdump.cpp:
138 - added command line switch -v to show dlsdump's revision and the used
139 libgig version
140

152 Version 1.0.0 (26 Nov 2004)
153
154 * packaging changes:
155 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
156 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
157 - fixed man pages automake install rule (which didn't work on Mandrake,
158 SuSE and Fedora)
159 - fixed generation of Doxygen API documentation (now also included in
160 RPM and Debian packages)
161
162 * src/gig.cpp, src/gig.h:
163 - fixed / improved accuracy of all three velocity to volume
164 transformation functions a.k.a. 'nonlinear','linear','special'
165 (patch by Andreas Persson)
166 - denormals are filtered from the velocity to volume tables
167 - bugfix for dimension region switching (wrong handling of the release
168 trigger dimension, no bit range check for dimensions of split type
169 'split_type_bit')
170 - fixed panorama value in DimensionRegion (invalid conversion from
171 signed 7 bit to signed 8 bit)
172 - added class attribute 'Layers' to class 'gig::Region'
173 - symbol prototyping of gig::Region (fixes build failure with qsampler)
174
175 * src/gigextract.cpp:
176 - added support for libsndfile (if libaudiofile and libsndfile are
177 available then libsndfile is preferred)
178
179 * src/gigdump.cpp:
180 - added printout for dimension informations (amount, type, bits, zones)
181 - added printout for velocity response curve parameters
182 - added printout for crossfade definitions
183 - added printout for panorama value for each DimensionRegion
184 - replaced printout of DLS Region layer by printout of amount of
185 Gigasampler layers
186
187 Version 0.7.1 (2 Jul 2004)
188
189 * packaging changes:
190 - added libgig.spec and libgig.pc package configurations for generating
191 Redhat packages
192 - header files included on installation.
193 - autotools-generated files removed from CVS repository.
194 - added support for generating Debian packages
195 - version of shared library can be set in configure.in
196
197 Version 0.7.0 (3 May 2004)
198
199 * general changes:
200 - various big endian specific corrections
201 (successfully tested now on PPC)
202 - minor adjustments to avoid compile errors on some systems
203 (using now pow() instead of powl() and --pedantic g++ compiler switch)
204 - libtoolized the library
205 - added man pages for the command line tools
206 (gigextract, gigdump, dlsdump, rifftree)
207
208 * src/gig.cpp, src/gig.h:
209 - fixed bug in decompression algorithm which caused it not to detect
210 the end of a stream
211 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
212 takes the MIDI key velocity value as an argument and returns the
213 appropriate volume factor (0.0 ... 1.0) for the sample to be played
214 back, the velocity curve transformation functions used for this are
215 only an approximation so far
216 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
217 'Sample::LoopSize' which reflected wrong values
218 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
219 measured in sample points instead of byte offset
220 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
221 'Sample::FineTune'
222 - added class attribute 'Sample::LoopSize'
223 - added method GetInstrument(uint index) to class 'File'
224 - added ReadAndLoop() method to class 'Sample' which is an extension to
225 the normal Read() method to honor the sample's looping information
226 while streaming from disk
227 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
228 'eg2_ctrl_t': replaced this huge enumeration by a structure which
229 reflects the MIDI controller number in case of an ordinary control
230 change controller (this saves a huge switch-case block in the
231 application of the library user)
232 - renamed following attributes in class 'DimensionRegion':
233 'AttenuationContol' -> 'AttenuationController',
234 'InvertAttenuationControl' -> 'InvertAttenuationController',
235 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
236 - minor fix in API documentation for method GetVelocityAttenuation() in
237 class 'DimensionRegion'
238
239 * src/RIFF.cpp, src/RIFF.h:
240 - added additional API documentation
241 - minor fix in Chunk::Read() method (only a minor efficiency issue)
242
243 * src/gigdump.cpp:
244 - added printout of samples' looping informations
245
246 Version 0.6.0 (3 Nov 2003)
247
248 * initial release
