* src/RIFF.cpp, src/RIFF.h:
  - Chunk::LoadChunkData() can now be called again to resize the buffer
    after a Chunk::Resize() and before the File::Save() call to allow
    placing the new data in the chunk's write buffer and perform the
    resize and write operations in one rush
* src/DLS.cpp, src/DLS.h:
  - fixed loading of Articulation Connections (<artl> list chunks were
    seeked instead of ordinary <artl> data chunks)
  - added write support (highly experimental)

1 Version CVS HEAD (?)
2
3 * general changes:
4 - added write support (only to the RIFF and DLS classes yet)
5
6 * src/gig.cpp, src/gig.h:
7 - fixed the GetVelocityCutoff function, it wasn't always using the
8 VCFVelocityScale parameter when no cutoff controller was defined
9 - support for the gig v3 feature to have a number of dimension
10 splits not equal to a power of two
11
12 * src/DLS.cpp, src/DLS.h:
13 - fixed loading of Articulation Connections (<artl> list chunks were
14 seeked instead of ordinary <artl> data chunks)
15 - added write support (highly experimental)
16
17 * src/RIFF.cpp, src/RIFF.h:
18 - added write support
19 - Chunk::LoadChunkData() can now be called again to resize the buffer
20 after a Chunk::Resize() and before the File::Save() call to allow
21 placing the new data in the chunk's write buffer and perform the
22 resize and write operations in one rush
23
24 Version 2.0.2 (15 Aug 2005)
25
26 * packaging changes:
27 - require automake (>= 1.5) for 'make -f Makefile.cvs'

29
30 * src/gig.cpp, src/gig.h:
31 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
32 the extension files are read automatically when the samples are
33 loaded
34 - fixed the 24 bit decompression, the result should now be exact
35 instead of an approximation
36 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
37 function to DimensionRegion
38
39 * src/DLS.cpp, src/DLS.h:
40 - the upper bits of the pool table indices are read (used as
41 extension file numbers for gig v3)
42
43 * src/RIFF.cpp, src/RIFF.h:
44 - the file name is remembered in the RIFF::File object
45
46 Version 2.0.1 (12 Jun 2005)
47

51
52 * src/gigextract.cpp:
53 - show also version of libsndfile or build version of libaudiofile when
54 using the -v switch
55 - fixed mutual link dependency to libsndfile / libaudiofile

58 - added DimensionRegion::GetVelocityRelease function
59
60 Version 2.0.0 (9 May 2005)
61
62 * packaging changes:
63 - fixed conditional linkage of either libsndfile or libaudiofile
64 (if none of the two exist, configure script will abort)
65 - man pages are now auto generated with the correct libgig version
66
67 * src/gig.cpp, src/gig.h:
68 - experimental support for Gigasampler v3 format;
69 64 bit file offsets are truncated to 32 bit, 24 bit samples are
70 truncated to 16 bit, up to 8 dimensions are read, additional
71 articulation informations are ignored at the moment
72 (patch by Andreas Persson)
73 - added some file format compatibility checks
74 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
75 never used, because the necessary check was made before
76 initialization)
77 - fixed crossfade points order (structure for big endian and little
78 endian systems was interchanged)
79 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
80 - fixed crash which occured when patches did not have a sample assigned
81 to their region or dimension region (patch by Andreas Persson)
82 - support for compressed mono samples
83 - experimental support for compressed 24 bit samples
84 - fixed decompression on big-endian CPUs
85 - fixed decompression bug that truncated the last block of samples
86 - external decompression buffers can now be used for streaming samples
87 to avoid race conditions in case of multiple streaming threads
88 - added pre-calculated sample attenuation parameter
89 - added v3 "random" and "round robin" dimensions
90 - implemented progress indicator callback mechanism for loading
91 instruments and samples
92 - added functions libraryName() and libraryVersion()
93

96 to be zero
97 - added functions libraryName() and libraryVersion()
98
99 * src/RIFF.cpp, src/RIFF.h:
100 - fixed method List::LoadSubChunks() which did not restore the original
101 position within the body of the given list chunk
102 - added functions libraryName() and libraryVersion()
103
104 * src/rifftree.cpp:
105 - added command line switch -v to show rifftree's revision and the used
106 libgig version
107
108 * src/dlsdump.cpp:
109 - added command line switch -v to show dlsdump's revision and the used
110 libgig version
111
112 * src/gigdump.cpp:
113 - added output of UnityNote, FineTune, Gain, SampleStartOffset an
114 LoopPlayCount
115 - added command line switch -v to show gigdump's revision and the used

122
123 Version 1.0.0 (26 Nov 2004)
124
125 * packaging changes:
126 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
127 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
128 - fixed man pages automake install rule (which didn't work on Mandrake,
129 SuSE and Fedora)
130 - fixed generation of Doxygen API documentation (now also included in
131 RPM and Debian packages)
132
133 * src/gig.cpp, src/gig.h:
134 - fixed / improved accuracy of all three velocity to volume
135 transformation functions a.k.a. 'nonlinear','linear','special'
136 (patch by Andreas Persson)
137 - denormals are filtered from the velocity to volume tables
138 - bugfix for dimension region switching (wrong handling of the release
139 trigger dimension, no bit range check for dimensions of split type
140 'split_type_bit')
141 - fixed panorama value in DimensionRegion (invalid conversion from
142 signed 7 bit to signed 8 bit)
143 - added class attribute 'Layers' to class 'gig::Region'
144 - symbol prototyping of gig::Region (fixes build failure with qsampler)
145
146 * src/gigextract.cpp:

151 - added printout for dimension informations (amount, type, bits, zones)
152 - added printout for velocity response curve parameters
153 - added printout for crossfade definitions
154 - added printout for panorama value for each DimensionRegion
155 - replaced printout of DLS Region layer by printout of amount of
156 Gigasampler layers
157
158 Version 0.7.1 (2 Jul 2004)
159
160 * packaging changes:
161 - added libgig.spec and libgig.pc package configurations for generating
162 Redhat packages
163 - header files included on installation.
164 - autotools-generated files removed from CVS repository.
165 - added support for generating Debian packages
166 - version of shared library can be set in configure.in
167
168 Version 0.7.0 (3 May 2004)
169
170 * general changes:
171 - various big endian specific corrections
172 (successfully tested now on PPC)
173 - minor adjustments to avoid compile errors on some systems
174 (using now pow() instead of powl() and --pedantic g++ compiler switch)
175 - libtoolized the library
176 - added man pages for the command line tools
177 (gigextract, gigdump, dlsdump, rifftree)
178
179 * src/gig.cpp, src/gig.h:
180 - fixed bug in decompression algorithm which caused it not to detect
181 the end of a stream
182 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
183 takes the MIDI key velocity value as an argument and returns the
184 appropriate volume factor (0.0 ... 1.0) for the sample to be played
185 back, the velocity curve transformation functions used for this are
186 only an approximation so far
187 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
188 'Sample::LoopSize' which reflected wrong values
189 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
190 measured in sample points instead of byte offset
191 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
192 'Sample::FineTune'
193 - added class attribute 'Sample::LoopSize'
194 - added method GetInstrument(uint index) to class 'File'
195 - added ReadAndLoop() method to class 'Sample' which is an extension to
196 the normal Read() method to honor the sample's looping information
197 while streaming from disk
198 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
199 'eg2_ctrl_t': replaced this huge enumeration by a structure which
200 reflects the MIDI controller number in case of an ordinary control
201 change controller (this saves a huge switch-case block in the
202 application of the library user)
203 - renamed following attributes in class 'DimensionRegion':
204 'AttenuationContol' -> 'AttenuationController',
205 'InvertAttenuationControl' -> 'InvertAttenuationController',
206 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
207 - minor fix in API documentation for method GetVelocityAttenuation() in
208 class 'DimensionRegion'
209
210 * src/RIFF.cpp, src/RIFF.h:
211 - added additional API documentation
212 - minor fix in Chunk::Read() method (only a minor efficiency issue)
213
214 * src/gigdump.cpp:
215 - added printout of samples' looping informations
216
217 Version 0.6.0 (3 Nov 2003)
218
219 * initial release
