* preparations for release 3.0.0

1 Version 3.0.0 (28 Apr 2006)
2
3 * general changes:
4 - added write support (that is for creating and modifying RIFF, DLS and
5 gig files)
6 - loading DLS and gig files is now much more permissive, DLS and gig
7 files are now loaded even if mandatory RIFF chunks are missing
8 - fixed some memory management errors, one of them was causing a
9 crash when a multi-file gig was deallocated
10
11 * src/gig.cpp, src/gig.h:
12 - fixed the GetVelocityCutoff function, it wasn't always using the
13 VCFVelocityScale parameter when no cutoff controller was defined
14 - support for the gig v3 feature to have a number of dimension
15 splits not equal to a power of two
16 - added write support (highly experimental)
17
18 * src/DLS.cpp, src/DLS.h:
19 - fixed loading of Articulation Connections (<artl> list chunks were
20 seeked instead of ordinary <artl> data chunks)
21 - added write support (highly experimental)
22
23 * src/RIFF.cpp, src/RIFF.h:
24 - added write support
25 - Chunk::LoadChunkData() can now be called again to resize the buffer
26 after a Chunk::Resize() and before the File::Save() call to allow
27 placing the new data in the chunk's write buffer and perform the
28 resize and write operations in one rush
29
30 * src/gigdump.cpp:
31 - fixed to show the correct amount of dimension regions instead of 32
32 (patch by James Wylder)
33
34 * src/dlsdump.cpp:
35 - show for every region the name of the referenced sample
36 - show file name in quotation marks
37
38 Version 2.0.2 (15 Aug 2005)
39
40 * packaging changes:
41 - require automake (>= 1.5) for 'make -f Makefile.cvs'
42 (mandatory for 'dist-bzip2' automake option)
43
44 * src/gig.cpp, src/gig.h:
45 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
46 the extension files are read automatically when the samples are
47 loaded
48 - fixed the 24 bit decompression, the result should now be exact
49 instead of an approximation
50 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
51 function to DimensionRegion
52
53 * src/DLS.cpp, src/DLS.h:
54 - the upper bits of the pool table indices are read (used as
55 extension file numbers for gig v3)
56
57 * src/RIFF.cpp, src/RIFF.h:
58 - the file name is remembered in the RIFF::File object
59
60 Version 2.0.1 (12 Jun 2005)
61
62 * packaging changes:
63 - include debian/ directory on 'make dist'
64 - create a bzip2 tarball on 'make dist'
65
66 * src/gigextract.cpp:
67 - show also version of libsndfile or build version of libaudiofile when
68 using the -v switch
69 - fixed mutual link dependency to libsndfile / libaudiofile
70
71 * src/gig.cpp, src/gig.h:
72 - added DimensionRegion::GetVelocityRelease function
73
74 Version 2.0.0 (9 May 2005)
75
76 * packaging changes:
77 - fixed conditional linkage of either libsndfile or libaudiofile
78 (if none of the two exist, configure script will abort)
79 - man pages are now auto generated with the correct libgig version
80
81 * src/gig.cpp, src/gig.h:
82 - experimental support for Gigasampler v3 format;
83 64 bit file offsets are truncated to 32 bit, 24 bit samples are
84 truncated to 16 bit, up to 8 dimensions are read, additional
85 articulation informations are ignored at the moment
86 (patch by Andreas Persson)
87 - added some file format compatibility checks
88 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
89 never used, because the necessary check was made before
90 initialization)
91 - fixed crossfade points order (structure for big endian and little
92 endian systems was interchanged)
93 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
94 - fixed crash which occured when patches did not have a sample assigned
95 to their region or dimension region (patch by Andreas Persson)
96 - support for compressed mono samples
97 - experimental support for compressed 24 bit samples
98 - fixed decompression on big-endian CPUs
99 - fixed decompression bug that truncated the last block of samples
100 - external decompression buffers can now be used for streaming samples
101 to avoid race conditions in case of multiple streaming threads
102 - added pre-calculated sample attenuation parameter
103 - added v3 "random" and "round robin" dimensions
104 - implemented progress indicator callback mechanism for loading
105 instruments and samples
106 - added functions libraryName() and libraryVersion()
107
108 * src/DLS.cpp, src/DLS.h:
109 - fixed File constructor which caused variable File::Instruments always
110 to be zero
111 - added functions libraryName() and libraryVersion()
112
113 * src/RIFF.cpp, src/RIFF.h:
114 - fixed method List::LoadSubChunks() which did not restore the original
115 position within the body of the given list chunk
116 - added functions libraryName() and libraryVersion()
117
118 * src/rifftree.cpp:
119 - added command line switch -v to show rifftree's revision and the used
120 libgig version
121
122 * src/dlsdump.cpp:
123 - added command line switch -v to show dlsdump's revision and the used
124 libgig version
125
126 * src/gigdump.cpp:
127 - added output of UnityNote, FineTune, Gain, SampleStartOffset an
128 LoopPlayCount
129 - added command line switch -v to show gigdump's revision and the used

134 - added command line switch -v to show gigextract's revision and the
135 used libgig version
136
137 Version 1.0.0 (26 Nov 2004)
138
139 * packaging changes:
140 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
141 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
142 - fixed man pages automake install rule (which didn't work on Mandrake,
143 SuSE and Fedora)
144 - fixed generation of Doxygen API documentation (now also included in
145 RPM and Debian packages)
146
147 * src/gig.cpp, src/gig.h:
148 - fixed / improved accuracy of all three velocity to volume
149 transformation functions a.k.a. 'nonlinear','linear','special'
150 (patch by Andreas Persson)
151 - denormals are filtered from the velocity to volume tables
152 - bugfix for dimension region switching (wrong handling of the release
153 trigger dimension, no bit range check for dimensions of split type
154 'split_type_bit')
155 - fixed panorama value in DimensionRegion (invalid conversion from
156 signed 7 bit to signed 8 bit)
157 - added class attribute 'Layers' to class 'gig::Region'
158 - symbol prototyping of gig::Region (fixes build failure with qsampler)
159
160 * src/gigextract.cpp:
161 - added support for libsndfile (if libaudiofile and libsndfile are
162 available then libsndfile is preferred)
163
164 * src/gigdump.cpp:
165 - added printout for dimension informations (amount, type, bits, zones)
166 - added printout for velocity response curve parameters
167 - added printout for crossfade definitions
168 - added printout for panorama value for each DimensionRegion
169 - replaced printout of DLS Region layer by printout of amount of
170 Gigasampler layers
171
172 Version 0.7.1 (2 Jul 2004)
173
174 * packaging changes:
175 - added libgig.spec and libgig.pc package configurations for generating
176 Redhat packages
177 - header files included on installation.
178 - autotools-generated files removed from CVS repository.
179 - added support for generating Debian packages
180 - version of shared library can be set in configure.in
181
182 Version 0.7.0 (3 May 2004)
183
184 * general changes:
185 - various big endian specific corrections
186 (successfully tested now on PPC)
187 - minor adjustments to avoid compile errors on some systems
188 (using now pow() instead of powl() and --pedantic g++ compiler switch)
189 - libtoolized the library
190 - added man pages for the command line tools
191 (gigextract, gigdump, dlsdump, rifftree)
192
193 * src/gig.cpp, src/gig.h:
194 - fixed bug in decompression algorithm which caused it not to detect
195 the end of a stream
196 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
197 takes the MIDI key velocity value as an argument and returns the
198 appropriate volume factor (0.0 ... 1.0) for the sample to be played
199 back, the velocity curve transformation functions used for this are
200 only an approximation so far
201 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
202 'Sample::LoopSize' which reflected wrong values
203 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
204 measured in sample points instead of byte offset
205 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
206 'Sample::FineTune'
207 - added class attribute 'Sample::LoopSize'
208 - added method GetInstrument(uint index) to class 'File'
209 - added ReadAndLoop() method to class 'Sample' which is an extension to
210 the normal Read() method to honor the sample's looping information
211 while streaming from disk
212 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
213 'eg2_ctrl_t': replaced this huge enumeration by a structure which
214 reflects the MIDI controller number in case of an ordinary control
215 change controller (this saves a huge switch-case block in the
216 application of the library user)
217 - renamed following attributes in class 'DimensionRegion':
218 'AttenuationContol' -> 'AttenuationController',
219 'InvertAttenuationControl' -> 'InvertAttenuationController',
220 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
221 - minor fix in API documentation for method GetVelocityAttenuation() in
222 class 'DimensionRegion'
223
224 * src/RIFF.cpp, src/RIFF.h:
225 - added additional API documentation
226 - minor fix in Chunk::Read() method (only a minor efficiency issue)
227
228 * src/gigdump.cpp:
229 - added printout of samples' looping informations
230
231 Version 0.6.0 (3 Nov 2003)
232
233 * initial release
