File size: 10264 byte(s)
* sample loop parameters are now taken from the DimensionRegion
  instead of the wave chunk
* keyswitching dimension is changed from split type "normal" to "bit"

1 Version CVS HEAD (?)
2
3 * src/gig.cpp, src/gig.h:
4 - added support for more than one set of custom velocity splits
5 inside a region (for example different velocity split levels for
6 pedal up and pedal down)
7 - sample loop parameters are now taken from the DimensionRegion
8 instead of the wave chunk
9 - keyswitching dimension is changed from split type "normal" to
10 "bit"
11
12 Version 3.0.0 (28 Apr 2006)
13
14 * general changes:
15 - added write support (that is for creating and modifying RIFF, DLS and
16 gig files)
17 - loading DLS and gig files is now much more permissive, DLS and gig
18 files are now loaded even if mandatory RIFF chunks are missing
19 - fixed some memory management errors, one of them was causing a
20 crash when a multi-file gig was deallocated
21
22 * src/gig.cpp, src/gig.h:
23 - fixed the GetVelocityCutoff function, it wasn't always using the
24 VCFVelocityScale parameter when no cutoff controller was defined
25 - support for the gig v3 feature to have a number of dimension
26 splits not equal to a power of two
27 - added write support (highly experimental)
28
29 * src/DLS.cpp, src/DLS.h:
30 - fixed loading of Articulation Connections (<artl> list chunks were
31 seeked instead of ordinary <artl> data chunks)
32 - added write support (highly experimental)
33
34 * src/RIFF.cpp, src/RIFF.h:
35 - added write support
36 - Chunk::LoadChunkData() can now be called again to resize the buffer
37 after a Chunk::Resize() and before the File::Save() call to allow
38 placing the new data in the chunk's write buffer and perform the
39 resize and write operations in one rush
40
41 * src/gigdump.cpp:
42 - fixed to show the correct amount of dimension regions instead of 32
43 (patch by James Wylder)
44
45 * src/dlsdump.cpp:
46 - show for every region the name of the referenced sample
47 - show file name in quotation marks
48
49 Version 2.0.2 (15 Aug 2005)
50
51 * packaging changes:
52 - require automake (>= 1.5) for 'make -f Makefile.cvs'
53 (mandatory for 'dist-bzip2' automake option)
54
55 * src/gig.cpp, src/gig.h:
56 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
57 the extension files are read automatically when the samples are
58 loaded
59 - fixed the 24 bit decompression, the result should now be exact
60 instead of an approximation
61 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
62 function to DimensionRegion
63
64 * src/DLS.cpp, src/DLS.h:
65 - the upper bits of the pool table indices are read (used as
66 extension file numbers for gig v3)
67
68 * src/RIFF.cpp, src/RIFF.h:
69 - the file name is remembered in the RIFF::File object
70
71 Version 2.0.1 (12 Jun 2005)
72
73 * packaging changes:
74 - include debian/ directory on 'make dist'
75 - create a bzip2 tarball on 'make dist'
76
77 * src/gigextract.cpp:
78 - show also version of libsndfile or build version of libaudiofile when
79 using the -v switch
80 - fixed mutual link dependency to libsndfile / libaudiofile
81
82 * src/gig.cpp, src/gig.h:
83 - added DimensionRegion::GetVelocityRelease function
84
85 Version 2.0.0 (9 May 2005)
86

88 - fixed conditional linkage of either libsndfile or libaudiofile
89 (if none of the two exist, configure script will abort)
90 - man pages are now auto generated with the correct libgig version
91
92 * src/gig.cpp, src/gig.h:
93 - experimental support for Gigasampler v3 format;
94 64 bit file offsets are truncated to 32 bit, 24 bit samples are
95 truncated to 16 bit, up to 8 dimensions are read, additional
96 articulation informations are ignored at the moment
97 (patch by Andreas Persson)
98 - added some file format compatibility checks
99 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
100 never used, because the necessary check was made before
101 initialization)
102 - fixed crossfade points order (structure for big endian and little
103 endian systems was interchanged)
104 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

106 to their region or dimension region (patch by Andreas Persson)
107 - support for compressed mono samples
108 - experimental support for compressed 24 bit samples
109 - fixed decompression on big-endian CPUs
110 - fixed decompression bug that truncated the last block of samples

149
150 * packaging changes:
151 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
152 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
153 - fixed man pages automake install rule (which didn't work on Mandrake,
154 SuSE and Fedora)
155 - fixed generation of Doxygen API documentation (now also included in
156 RPM and Debian packages)
157
158 * src/gig.cpp, src/gig.h:
159 - fixed / improved accuracy of all three velocity to volume
160 transformation functions a.k.a. 'nonlinear','linear','special'
161 (patch by Andreas Persson)
162 - denormals are filtered from the velocity to volume tables
163 - bugfix for dimension region switching (wrong handling of the release
164 trigger dimension, no bit range check for dimensions of split type
165 'split_type_bit')
166 - fixed panorama value in DimensionRegion (invalid conversion from
167 signed 7 bit to signed 8 bit)
168 - added class attribute 'Layers' to class 'gig::Region'
169 - symbol prototyping of gig::Region (fixes build failure with qsampler)
170
171 * src/gigextract.cpp:

178 - added printout for crossfade definitions
179 - added printout for panorama value for each DimensionRegion
180 - replaced printout of DLS Region layer by printout of amount of
181 Gigasampler layers
182
183 Version 0.7.1 (2 Jul 2004)
184
185 * packaging changes:
186 - added libgig.spec and libgig.pc package configurations for generating
187 Redhat packages
188 - header files included on installation.
189 - autotools-generated files removed from CVS repository.
190 - added support for generating Debian packages
191 - version of shared library can be set in configure.in
192
193 Version 0.7.0 (3 May 2004)
194
195 * general changes:
196 - various big endian specific corrections
197 (successfully tested now on PPC)
198 - minor adjustments to avoid compile errors on some systems
199 (using now pow() instead of powl() and --pedantic g++ compiler switch)
200 - libtoolized the library
201 - added man pages for the command line tools
202 (gigextract, gigdump, dlsdump, rifftree)
203
204 * src/gig.cpp, src/gig.h:
205 - fixed bug in decompression algorithm which caused it not to detect
206 the end of a stream
207 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
208 takes the MIDI key velocity value as an argument and returns the
209 appropriate volume factor (0.0 ... 1.0) for the sample to be played
210 back, the velocity curve transformation functions used for this are
211 only an approximation so far
212 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
213 'Sample::LoopSize' which reflected wrong values
214 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
215 measured in sample points instead of byte offset
216 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
217 'Sample::FineTune'
218 - added class attribute 'Sample::LoopSize'
219 - added method GetInstrument(uint index) to class 'File'
220 - added ReadAndLoop() method to class 'Sample' which is an extension to
221 the normal Read() method to honor the sample's looping information
222 while streaming from disk
223 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
224 'eg2_ctrl_t': replaced this huge enumeration by a structure which
225 reflects the MIDI controller number in case of an ordinary control
226 change controller (this saves a huge switch-case block in the
227 application of the library user)
228 - renamed following attributes in class 'DimensionRegion':
229 'AttenuationContol' -> 'AttenuationController',
230 'InvertAttenuationControl' -> 'InvertAttenuationController',
231 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
232 - minor fix in API documentation for method GetVelocityAttenuation() in
233 class 'DimensionRegion'
234
235 * src/RIFF.cpp, src/RIFF.h:
236 - added additional API documentation
237 - minor fix in Chunk::Read() method (only a minor efficiency issue)
238
239 * src/gigdump.cpp:
240 - added printout of samples' looping informations
241
242 Version 0.6.0 (3 Nov 2003)
243
244 * initial release
