File size: 12068 byte(s)
* fixed crash which occured on interfering File::DeleteSample() and
  File::GetNextSample() calls (due to iterator invalidation)

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 - fixed crash which occured on interfering File::DeleteSample() and
18 File::GetNextSample() calls (due to iterator invalidation)
19
20 Version 3.1.0 (24 Nov 2006)
21
22 * packaging changes:
23 - changed deprecated copyright attribute to license;
24 added ldconfig to post-(un)install steps on libgig.spec (RPM)
25
26 * src/gig.cpp, src/gig.h:
27 - added support for more than one set of custom velocity splits
28 inside a region (for example different velocity split levels for
29 pedal up and pedal down)
30 - sample loop parameters are now taken from the DimensionRegion
31 instead of the wave chunk
32 - keyswitching dimension is changed from split type "normal" to
33 "bit"
34 - real support for 24 bit samples - samples are not truncated to
35 16 bits anymore
36 - support for reading of ".art" files. (Merging of .art and .gig
37 files are not implemented yet.)
38 - several fixes for the write support
39 - support for sample groups added
40
41 * src/DLS.cpp, src/DLS.h:
42 - support for reading of ".art" files

44 Jeremy Kerr)
45 - several fixes for the write support
46
47 * src/gigextract.cpp:
48 - real support for 24 bit samples
49
50 * src/gigdump.cpp:
51 - print global file informations
52 - print sample groups
53
54 * general changes:
55 - added CPPUnit test cases (at the moment primarily for automatic check
56 of Gigasampler write support)
57
58 Version 3.0.0 (28 Apr 2006)
59
60 * general changes:
61 - added write support (that is for creating and modifying RIFF, DLS and
62 gig files)
63 - loading DLS and gig files is now much more permissive, DLS and gig
64 files are now loaded even if mandatory RIFF chunks are missing
65 - fixed some memory management errors, one of them was causing a
66 crash when a multi-file gig was deallocated
67
68 * src/gig.cpp, src/gig.h:
69 - fixed the GetVelocityCutoff function, it wasn't always using the
70 VCFVelocityScale parameter when no cutoff controller was defined
71 - support for the gig v3 feature to have a number of dimension
72 splits not equal to a power of two
73 - added write support (highly experimental)
74
75 * src/DLS.cpp, src/DLS.h:
76 - fixed loading of Articulation Connections (<artl> list chunks were
77 seeked instead of ordinary <artl> data chunks)
78 - added write support (highly experimental)
79
80 * src/RIFF.cpp, src/RIFF.h:
81 - added write support
82 - Chunk::LoadChunkData() can now be called again to resize the buffer
83 after a Chunk::Resize() and before the File::Save() call to allow
84 placing the new data in the chunk's write buffer and perform the
85 resize and write operations in one rush
86
87 * src/gigdump.cpp:
88 - fixed to show the correct amount of dimension regions instead of 32
89 (patch by James Wylder)
90
91 * src/dlsdump.cpp:
92 - show for every region the name of the referenced sample
93 - show file name in quotation marks
94

98 - require automake (>= 1.5) for 'make -f Makefile.cvs'
99 (mandatory for 'dist-bzip2' automake option)
100
101 * src/gig.cpp, src/gig.h:
102 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
103 the extension files are read automatically when the samples are
104 loaded
105 - fixed the 24 bit decompression, the result should now be exact
106 instead of an approximation
107 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
108 function to DimensionRegion
109
110 * src/DLS.cpp, src/DLS.h:
111 - the upper bits of the pool table indices are read (used as
112 extension file numbers for gig v3)
113
114 * src/RIFF.cpp, src/RIFF.h:
115 - the file name is remembered in the RIFF::File object
116

137
138 * src/gig.cpp, src/gig.h:
139 - experimental support for Gigasampler v3 format;
140 64 bit file offsets are truncated to 32 bit, 24 bit samples are
141 truncated to 16 bit, up to 8 dimensions are read, additional
142 articulation informations are ignored at the moment
143 (patch by Andreas Persson)
144 - added some file format compatibility checks
145 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
146 never used, because the necessary check was made before

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

215 - symbol prototyping of gig::Region (fixes build failure with qsampler)
216

228
229 Version 0.7.1 (2 Jul 2004)
230
231 * packaging changes:
232 - added libgig.spec and libgig.pc package configurations for generating
233 Redhat packages
234 - header files included on installation.
235 - autotools-generated files removed from CVS repository.
236 - added support for generating Debian packages
237 - version of shared library can be set in configure.in
238
239 Version 0.7.0 (3 May 2004)
240
241 * general changes:
242 - various big endian specific corrections
243 (successfully tested now on PPC)
244 - minor adjustments to avoid compile errors on some systems
245 (using now pow() instead of powl() and --pedantic g++ compiler switch)
246 - libtoolized the library
247 - added man pages for the command line tools
248 (gigextract, gigdump, dlsdump, rifftree)
249
250 * src/gig.cpp, src/gig.h:
251 - fixed bug in decompression algorithm which caused it not to detect
252 the end of a stream
253 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
254 takes the MIDI key velocity value as an argument and returns the
255 appropriate volume factor (0.0 ... 1.0) for the sample to be played
256 back, the velocity curve transformation functions used for this are
257 only an approximation so far
258 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
259 'Sample::LoopSize' which reflected wrong values
260 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
261 measured in sample points instead of byte offset
262 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
263 'Sample::FineTune'
264 - added class attribute 'Sample::LoopSize'
265 - added method GetInstrument(uint index) to class 'File'
266 - added ReadAndLoop() method to class 'Sample' which is an extension to
267 the normal Read() method to honor the sample's looping information
268 while streaming from disk
269 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
270 'eg2_ctrl_t': replaced this huge enumeration by a structure which
271 reflects the MIDI controller number in case of an ordinary control
272 change controller (this saves a huge switch-case block in the
273 application of the library user)
274 - renamed following attributes in class 'DimensionRegion':
275 'AttenuationContol' -> 'AttenuationController',
276 'InvertAttenuationControl' -> 'InvertAttenuationController',
277 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
278 - minor fix in API documentation for method GetVelocityAttenuation() in
279 class 'DimensionRegion'
280
281 * src/RIFF.cpp, src/RIFF.h:
282 - added additional API documentation
283 - minor fix in Chunk::Read() method (only a minor efficiency issue)
284
285 * src/gigdump.cpp:
286 - added printout of samples' looping informations
287
288 Version 0.6.0 (3 Nov 2003)
289
290 * initial release
