* added new method File::DeleteGroupOnly() which only deletes the given
  group but moves all its members to another group, the other method,
  that is File::DeleteGroup() now removes not just the group, but also
  all the samples that belong to that group

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - ported to Windows using native Windows functions for file IO
5 (provided Dev-C++ + mingw project file)
6 - only export relevant files to Doxygen API documentation
7
8 * src/gig.cpp, src/gig.h:
9 - custom velocity splits now works for gig v3 files too
10 - added support for custom splits points for other dimensions than
11 velocity (gig v3 feature)
12 - added "smart midi" and "round robin keyboard" dimensions
13 - added new method File::DeleteGroupOnly() which only deletes the given
14 group but moves all its members to another group, the other method,
15 that is File::DeleteGroup() now removes not just the group, but also
16 all the samples that belong to that group
17
18 Version 3.1.0 (24 Nov 2006)
19
20 * packaging changes:
21 - changed deprecated copyright attribute to license;
22 added ldconfig to post-(un)install steps on libgig.spec (RPM)
23
24 * src/gig.cpp, src/gig.h:
25 - added support for more than one set of custom velocity splits
26 inside a region (for example different velocity split levels for
27 pedal up and pedal down)
28 - sample loop parameters are now taken from the DimensionRegion
29 instead of the wave chunk
30 - keyswitching dimension is changed from split type "normal" to
31 "bit"
32 - real support for 24 bit samples - samples are not truncated to
33 16 bits anymore
34 - support for reading of ".art" files. (Merging of .art and .gig
35 files are not implemented yet.)
36 - several fixes for the write support
37 - support for sample groups added
38
39 * src/DLS.cpp, src/DLS.h:
40 - support for reading of ".art" files

42 Jeremy Kerr)
43 - several fixes for the write support
44
45 * src/gigextract.cpp:
46 - real support for 24 bit samples
47
48 * src/gigdump.cpp:
49 - print global file informations
50 - print sample groups
51
52 * general changes:
53 - added CPPUnit test cases (at the moment primarily for automatic check
54 of Gigasampler write support)
55
56 Version 3.0.0 (28 Apr 2006)
57
58 * general changes:
59 - added write support (that is for creating and modifying RIFF, DLS and
60 gig files)
61 - loading DLS and gig files is now much more permissive, DLS and gig
62 files are now loaded even if mandatory RIFF chunks are missing
63 - fixed some memory management errors, one of them was causing a
64 crash when a multi-file gig was deallocated
65
66 * src/gig.cpp, src/gig.h:
67 - fixed the GetVelocityCutoff function, it wasn't always using the
68 VCFVelocityScale parameter when no cutoff controller was defined
69 - support for the gig v3 feature to have a number of dimension
70 splits not equal to a power of two
71 - added write support (highly experimental)
72
73 * src/DLS.cpp, src/DLS.h:
74 - fixed loading of Articulation Connections (<artl> list chunks were
75 seeked instead of ordinary <artl> data chunks)
76 - added write support (highly experimental)
77
78 * src/RIFF.cpp, src/RIFF.h:
79 - added write support
80 - Chunk::LoadChunkData() can now be called again to resize the buffer
81 after a Chunk::Resize() and before the File::Save() call to allow
82 placing the new data in the chunk's write buffer and perform the
83 resize and write operations in one rush
84
85 * src/gigdump.cpp:
86 - fixed to show the correct amount of dimension regions instead of 32
87 (patch by James Wylder)
88
89 * src/dlsdump.cpp:
90 - show for every region the name of the referenced sample
91 - show file name in quotation marks
92

94
95 * packaging changes:
96 - require automake (>= 1.5) for 'make -f Makefile.cvs'
97 (mandatory for 'dist-bzip2' automake option)
98
99 * src/gig.cpp, src/gig.h:
100 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
101 the extension files are read automatically when the samples are
102 loaded
103 - fixed the 24 bit decompression, the result should now be exact
104 instead of an approximation
105 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
106 function to DimensionRegion
107
108 * src/DLS.cpp, src/DLS.h:
109 - the upper bits of the pool table indices are read (used as
110 extension file numbers for gig v3)
111
112 * src/RIFF.cpp, src/RIFF.h:
113 - the file name is remembered in the RIFF::File object
114

133 (if none of the two exist, configure script will abort)
134 - man pages are now auto generated with the correct libgig version
135
136 * src/gig.cpp, src/gig.h:
137 - experimental support for Gigasampler v3 format;
138 64 bit file offsets are truncated to 32 bit, 24 bit samples are
139 truncated to 16 bit, up to 8 dimensions are read, additional
140 articulation informations are ignored at the moment
141 (patch by Andreas Persson)
142 - added some file format compatibility checks
143 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
144 never used, because the necessary check was made before
145 initialization)
146 - fixed crossfade points order (structure for big endian and little
147 endian systems was interchanged)
148 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

192 Version 1.0.0 (26 Nov 2004)
193
194 * packaging changes:
195 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
196 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
197 - fixed man pages automake install rule (which didn't work on Mandrake,
198 SuSE and Fedora)
199 - fixed generation of Doxygen API documentation (now also included in
200 RPM and Debian packages)
201
202 * src/gig.cpp, src/gig.h:
203 - fixed / improved accuracy of all three velocity to volume
204 transformation functions a.k.a. 'nonlinear','linear','special'
205 (patch by Andreas Persson)
206 - denormals are filtered from the velocity to volume tables
207 - bugfix for dimension region switching (wrong handling of the release
208 trigger dimension, no bit range check for dimensions of split type
209 'split_type_bit')

213 - symbol prototyping of gig::Region (fixes build failure with qsampler)
214
215 * src/gigextract.cpp:

225 Gigasampler layers
226
227 Version 0.7.1 (2 Jul 2004)
228
229 * packaging changes:
230 - added libgig.spec and libgig.pc package configurations for generating
231 Redhat packages
232 - header files included on installation.
233 - autotools-generated files removed from CVS repository.
234 - added support for generating Debian packages
235 - version of shared library can be set in configure.in
236
237 Version 0.7.0 (3 May 2004)
238
239 * general changes:
240 - various big endian specific corrections
241 (successfully tested now on PPC)
242 - minor adjustments to avoid compile errors on some systems
243 (using now pow() instead of powl() and --pedantic g++ compiler switch)
244 - libtoolized the library
245 - added man pages for the command line tools
246 (gigextract, gigdump, dlsdump, rifftree)
247
248 * src/gig.cpp, src/gig.h:
249 - fixed bug in decompression algorithm which caused it not to detect
250 the end of a stream
251 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
252 takes the MIDI key velocity value as an argument and returns the
253 appropriate volume factor (0.0 ... 1.0) for the sample to be played
254 back, the velocity curve transformation functions used for this are
255 only an approximation so far
256 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
257 'Sample::LoopSize' which reflected wrong values
258 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
259 measured in sample points instead of byte offset
260 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
261 'Sample::FineTune'
262 - added class attribute 'Sample::LoopSize'
263 - added method GetInstrument(uint index) to class 'File'
264 - added ReadAndLoop() method to class 'Sample' which is an extension to
265 the normal Read() method to honor the sample's looping information
266 while streaming from disk
267 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
268 'eg2_ctrl_t': replaced this huge enumeration by a structure which
269 reflects the MIDI controller number in case of an ordinary control
270 change controller (this saves a huge switch-case block in the
271 application of the library user)
272 - renamed following attributes in class 'DimensionRegion':
273 'AttenuationContol' -> 'AttenuationController',
274 'InvertAttenuationControl' -> 'InvertAttenuationController',
275 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
276 - minor fix in API documentation for method GetVelocityAttenuation() in
277 class 'DimensionRegion'
278
279 * src/RIFF.cpp, src/RIFF.h:
280 - added additional API documentation
281 - minor fix in Chunk::Read() method (only a minor efficiency issue)
282
283 * src/gigdump.cpp:
284 - added printout of samples' looping informations
285
286 Version 0.6.0 (3 Nov 2003)
287
288 * initial release
