* several fixes for the write support

1 persson 858 Version CVS HEAD (?)
2    
3 capela 867 * packaging changes:
4     - changed deprecated copyright attribute to license;
5     added ldconfig to post-(un)install steps on libgig.spec (RPM)
6 persson 902
7 persson 858 * src/gig.cpp, src/gig.h:
8     - added support for more than one set of custom velocity splits
9     inside a region (for example different velocity split levels for
10     pedal up and pedal down)
11 persson 864 - sample loop parameters are now taken from the DimensionRegion
12     instead of the wave chunk
13     - keyswitching dimension is changed from split type "normal" to
14     "bit"
15 persson 902 - real support for 24 bit samples - samples are not truncated to
16     16 bits anymore
17     - support for reading of ".art" files. (Merging of .art and .gig
18     files are not implemented yet.)
19 persson 918 - several fixes for the write support
20 persson 858
21 persson 918 * src/DLS.cpp, src/DLS.h:
22 persson 902 - support for reading of ".art" files

24     Jeremy Kerr)
25     - several fixes for the write support
26 persson 902
27     * src/gigextract.cpp:
28     - real support for 24 bit samples
29    
30 schoenebeck 916 * src/gigdump.cpp:
31     - print global file informations
32

36    
37 schoenebeck 854 Version 3.0.0 (28 Apr 2006)
38 persson 773
39 schoenebeck 780 * general changes:
40 schoenebeck 809 - added write support (that is for creating and modifying RIFF, DLS and
41     gig files)
42     - loading DLS and gig files is now much more permissive, DLS and gig
43     files are now loaded even if mandatory RIFF chunks are missing
44 persson 834 - fixed some memory management errors, one of them was causing a
45     crash when a multi-file gig was deallocated
46 schoenebeck 780
47 persson 773 * src/gig.cpp, src/gig.h:
48     - fixed the GetVelocityCutoff function, it wasn't always using the

53 persson 773
54 schoenebeck 800 * src/DLS.cpp, src/DLS.h:

56     seeked instead of ordinary <artl> data chunks)
57     - added write support (highly experimental)
58    
59     * src/RIFF.cpp, src/RIFF.h:
60     - added write support
61     - Chunk::LoadChunkData() can now be called again to resize the buffer
62     after a Chunk::Resize() and before the File::Save() call to allow
63     placing the new data in the chunk's write buffer and perform the
64     resize and write operations in one rush
65    
66 schoenebeck 809 * src/gigdump.cpp:
67     - fixed to show the correct amount of dimension regions instead of 32
68     (patch by James Wylder)
69    
70 schoenebeck 804 * src/dlsdump.cpp:
71     - show for every region the name of the referenced sample

174 schoenebeck 196
175     * packaging changes:
176     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

185 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
186     (patch by Andreas Persson)
187 schoenebeck 231 - denormals are filtered from the velocity to volume tables
188 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
189     trigger dimension, no bit range check for dimensions of split type
190     'split_type_bit')
191 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
192     signed 7 bit to signed 8 bit)
193 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
194 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
195 schoenebeck 231
196 schoenebeck 220 * src/gigextract.cpp:
197     - added support for libsndfile (if libaudiofile and libsndfile are

207 schoenebeck 229
208 capela 168 Version 0.7.1 (2 Jul 2004)
209    
210     * packaging changes:
211 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
212     Redhat packages
213 capela 168 - header files included on installation.
214     - autotools-generated files removed from CVS repository.
215 schoenebeck 186 - added support for generating Debian packages
216     - version of shared library can be set in configure.in
217    
218 schoenebeck 58 Version 0.7.0 (3 May 2004)
219    
220     * general changes:
221     - various big endian specific corrections
222     (successfully tested now on PPC)
223     - minor adjustments to avoid compile errors on some systems
224     (using now pow() instead of powl() and --pedantic g++ compiler switch)
225     - libtoolized the library
226     - added man pages for the command line tools
227     (gigextract, gigdump, dlsdump, rifftree)
228    
229     * src/gig.cpp, src/gig.h:
230     - fixed bug in decompression algorithm which caused it not to detect
231     the end of a stream
232     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
233     takes the MIDI key velocity value as an argument and returns the
234     appropriate volume factor (0.0 ... 1.0) for the sample to be played
235     back, the velocity curve transformation functions used for this are
236     only an approximation so far
237     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
238     'Sample::LoopSize' which reflected wrong values
239     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
240     measured in sample points instead of byte offset
241     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
242     'Sample::FineTune'
243     - added class attribute 'Sample::LoopSize'
244     - added method GetInstrument(uint index) to class 'File'
245     - added ReadAndLoop() method to class 'Sample' which is an extension to
246     the normal Read() method to honor the sample's looping information
247     while streaming from disk
248     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
249     'eg2_ctrl_t': replaced this huge enumeration by a structure which
250     reflects the MIDI controller number in case of an ordinary control
251     change controller (this saves a huge switch-case block in the
252     application of the library user)
253     - renamed following attributes in class 'DimensionRegion':
254     'AttenuationContol' -> 'AttenuationController',
255     'InvertAttenuationControl' -> 'InvertAttenuationController',
256     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
257     - minor fix in API documentation for method GetVelocityAttenuation() in
258     class 'DimensionRegion'
259    
260     * src/RIFF.cpp, src/RIFF.h:
261     - added additional API documentation
262     - minor fix in Chunk::Read() method (only a minor efficiency issue)
263    
264     * src/gigdump.cpp:
265     - added printout of samples' looping informations
266    
267 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
268    
269     * initial release
