* ported to Windows using native Windows functions for file IO
  (provided Dev-C++ + mingw project file)
* renamed macro WAVE_FORMAT_PCM to DLS_WAVE_FORMAT_PCM
  to avoid clash with definition in i.e. windows.h

1 Version CVS HEAD (?)

3 * packaging changes:
4 - ported to Windows using native Windows functions for file IO
5 (provided Dev-C++ + mingw project file)
6
7 Version 3.1.0 (24 Nov 2006)
8
9 * packaging changes:
10 - changed deprecated copyright attribute to license;
11 added ldconfig to post-(un)install steps on libgig.spec (RPM)
12
13 * src/gig.cpp, src/gig.h:
14 - added support for more than one set of custom velocity splits
15 inside a region (for example different velocity split levels for
16 pedal up and pedal down)
17 - sample loop parameters are now taken from the DimensionRegion
18 instead of the wave chunk
19 - keyswitching dimension is changed from split type "normal" to
20 "bit"
21 - real support for 24 bit samples - samples are not truncated to
22 16 bits anymore
23 - support for reading of ".art" files. (Merging of .art and .gig
24 files are not implemented yet.)
25 - several fixes for the write support
26 - support for sample groups added
27
28 * src/DLS.cpp, src/DLS.h:
29 - support for reading of ".art" files

31 Jeremy Kerr)
32 - several fixes for the write support
33
34 * src/gigextract.cpp:
35 - real support for 24 bit samples
36
37 * src/gigdump.cpp:
38 - print global file informations
39 - print sample groups
40
41 * general changes:
42 - added CPPUnit test cases (at the moment primarily for automatic check
43 of Gigasampler write support)
44
45 Version 3.0.0 (28 Apr 2006)
46
47 * general changes:
48 - added write support (that is for creating and modifying RIFF, DLS and
49 gig files)
50 - loading DLS and gig files is now much more permissive, DLS and gig
51 files are now loaded even if mandatory RIFF chunks are missing
52 - fixed some memory management errors, one of them was causing a
53 crash when a multi-file gig was deallocated
54
55 * src/gig.cpp, src/gig.h:
56 - fixed the GetVelocityCutoff function, it wasn't always using the
57 VCFVelocityScale parameter when no cutoff controller was defined
58 - support for the gig v3 feature to have a number of dimension
59 splits not equal to a power of two
60 - added write support (highly experimental)
61
62 * src/DLS.cpp, src/DLS.h:
63 - fixed loading of Articulation Connections (<artl> list chunks were
64 seeked instead of ordinary <artl> data chunks)
65 - added write support (highly experimental)
66
67 * src/RIFF.cpp, src/RIFF.h:
68 - added write support
69 - Chunk::LoadChunkData() can now be called again to resize the buffer
70 after a Chunk::Resize() and before the File::Save() call to allow
71 placing the new data in the chunk's write buffer and perform the
72 resize and write operations in one rush
73
74 * src/gigdump.cpp:
75 - fixed to show the correct amount of dimension regions instead of 32
76 (patch by James Wylder)
77
78 * src/dlsdump.cpp:
79 - show for every region the name of the referenced sample
80 - show file name in quotation marks
81

83
84 * packaging changes:
85 - require automake (>= 1.5) for 'make -f Makefile.cvs'
86 (mandatory for 'dist-bzip2' automake option)
87
88 * src/gig.cpp, src/gig.h:
89 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
90 the extension files are read automatically when the samples are
91 loaded
92 - fixed the 24 bit decompression, the result should now be exact
93 instead of an approximation
94 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
95 function to DimensionRegion
96
97 * src/DLS.cpp, src/DLS.h:
98 - the upper bits of the pool table indices are read (used as
99 extension file numbers for gig v3)
100
101 * src/RIFF.cpp, src/RIFF.h:
102 - the file name is remembered in the RIFF::File object
103

122 (if none of the two exist, configure script will abort)
123 - man pages are now auto generated with the correct libgig version
124
125 * src/gig.cpp, src/gig.h:
126 - experimental support for Gigasampler v3 format;
127 64 bit file offsets are truncated to 32 bit, 24 bit samples are
128 truncated to 16 bit, up to 8 dimensions are read, additional
129 articulation informations are ignored at the moment
130 (patch by Andreas Persson)
131 - added some file format compatibility checks
132 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
133 never used, because the necessary check was made before
134 initialization)
135 - fixed crossfade points order (structure for big endian and little
136 endian systems was interchanged)
137 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

182
183 * packaging changes:
184 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
185 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
186 - fixed man pages automake install rule (which didn't work on Mandrake,
187 SuSE and Fedora)
188 - fixed generation of Doxygen API documentation (now also included in
189 RPM and Debian packages)
190
191 * src/gig.cpp, src/gig.h:
192 - fixed / improved accuracy of all three velocity to volume
193 transformation functions a.k.a. 'nonlinear','linear','special'
194 (patch by Andreas Persson)
195 - denormals are filtered from the velocity to volume tables
196 - bugfix for dimension region switching (wrong handling of the release
197 trigger dimension, no bit range check for dimensions of split type
198 'split_type_bit')
199 - fixed panorama value in DimensionRegion (invalid conversion from
200 signed 7 bit to signed 8 bit)
201 - added class attribute 'Layers' to class 'gig::Region'
202 - symbol prototyping of gig::Region (fixes build failure with qsampler)
203
204 * src/gigextract.cpp:

206 available then libsndfile is preferred)
207
208 * src/gigdump.cpp:
209 - added printout for dimension informations (amount, type, bits, zones)
210 - added printout for velocity response curve parameters
211 - added printout for crossfade definitions
212 - added printout for panorama value for each DimensionRegion
213 - replaced printout of DLS Region layer by printout of amount of
214 Gigasampler layers
215
216 Version 0.7.1 (2 Jul 2004)
217
218 * packaging changes:
219 - added libgig.spec and libgig.pc package configurations for generating
220 Redhat packages
221 - header files included on installation.
222 - autotools-generated files removed from CVS repository.
223 - added support for generating Debian packages
224 - version of shared library can be set in configure.in
225
226 Version 0.7.0 (3 May 2004)
227
228 * general changes:
229 - various big endian specific corrections
230 (successfully tested now on PPC)
231 - minor adjustments to avoid compile errors on some systems
232 (using now pow() instead of powl() and --pedantic g++ compiler switch)
233 - libtoolized the library
234 - added man pages for the command line tools
235 (gigextract, gigdump, dlsdump, rifftree)
236
237 * src/gig.cpp, src/gig.h:
238 - fixed bug in decompression algorithm which caused it not to detect
239 the end of a stream
240 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
241 takes the MIDI key velocity value as an argument and returns the
242 appropriate volume factor (0.0 ... 1.0) for the sample to be played
243 back, the velocity curve transformation functions used for this are
244 only an approximation so far
245 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
246 'Sample::LoopSize' which reflected wrong values
247 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
248 measured in sample points instead of byte offset
249 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
250 'Sample::FineTune'
251 - added class attribute 'Sample::LoopSize'
252 - added method GetInstrument(uint index) to class 'File'
253 - added ReadAndLoop() method to class 'Sample' which is an extension to
254 the normal Read() method to honor the sample's looping information
255 while streaming from disk
256 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
257 'eg2_ctrl_t': replaced this huge enumeration by a structure which
258 reflects the MIDI controller number in case of an ordinary control
259 change controller (this saves a huge switch-case block in the
260 application of the library user)
261 - renamed following attributes in class 'DimensionRegion':
262 'AttenuationContol' -> 'AttenuationController',
263 'InvertAttenuationControl' -> 'InvertAttenuationController',
264 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
265 - minor fix in API documentation for method GetVelocityAttenuation() in
266 class 'DimensionRegion'
267
268 * src/RIFF.cpp, src/RIFF.h:
269 - added additional API documentation
270 - minor fix in Chunk::Read() method (only a minor efficiency issue)
271
272 * src/gigdump.cpp:
273 - added printout of samples' looping informations
274
275 Version 0.6.0 (3 Nov 2003)
276
277 * initial release
