* src/gig.cpp, src/gig.h:
  - added write support (highly experimental)
  - removed unnecessary definitions from header file
* src/DLS.cpp:
  - try to load instruments/samples before adding a new instrument/sample

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

108 to be zero
109 - added functions libraryName() and libraryVersion()
110
111 * src/RIFF.cpp, src/RIFF.h:
112 - fixed method List::LoadSubChunks() which did not restore the original
113 position within the body of the given list chunk
114 - added functions libraryName() and libraryVersion()
115
116 * src/rifftree.cpp:
117 - added command line switch -v to show rifftree's revision and the used
118 libgig version
119
120 * src/dlsdump.cpp:
121 - added command line switch -v to show dlsdump's revision and the used
122 libgig version
123
124 * src/gigdump.cpp:
125 - added output of UnityNote, FineTune, Gain, SampleStartOffset an
126 LoopPlayCount
127 - added command line switch -v to show gigdump's revision and the used

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