* real support for 24 bit samples
* support for reading of .art files

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 858
20 persson 902 * src/DLS.cpp:
21     - support for reading of ".art" files
22    
23     * src/gigextract.cpp:

25    
26 schoenebeck 854 Version 3.0.0 (28 Apr 2006)
27 persson 773
28 schoenebeck 780 * general changes:
29 schoenebeck 809 - added write support (that is for creating and modifying RIFF, DLS and
30     gig files)
31     - loading DLS and gig files is now much more permissive, DLS and gig
32     files are now loaded even if mandatory RIFF chunks are missing
33 persson 834 - fixed some memory management errors, one of them was causing a
34     crash when a multi-file gig was deallocated
35 schoenebeck 780
36 persson 773 * src/gig.cpp, src/gig.h:
37     - fixed the GetVelocityCutoff function, it wasn't always using the
38     VCFVelocityScale parameter when no cutoff controller was defined
39 persson 774 - support for the gig v3 feature to have a number of dimension
40     splits not equal to a power of two
41 schoenebeck 809 - added write support (highly experimental)
42 persson 773
43 schoenebeck 800 * src/DLS.cpp, src/DLS.h:
44     - fixed loading of Articulation Connections (<artl> list chunks were
45     seeked instead of ordinary <artl> data chunks)
46     - added write support (highly experimental)
47    
48     * src/RIFF.cpp, src/RIFF.h:
49     - added write support
50     - Chunk::LoadChunkData() can now be called again to resize the buffer
51     after a Chunk::Resize() and before the File::Save() call to allow
52     placing the new data in the chunk's write buffer and perform the
53     resize and write operations in one rush
54    
55 schoenebeck 809 * src/gigdump.cpp:
56     - fixed to show the correct amount of dimension regions instead of 32
57     (patch by James Wylder)
58    
59 schoenebeck 804 * src/dlsdump.cpp:
60     - show for every region the name of the referenced sample

68    
69 persson 666 * src/gig.cpp, src/gig.h:
70     - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),

74     instead of an approximation
75 persson 728 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
76     function to DimensionRegion
77 persson 666
78     * src/DLS.cpp, src/DLS.h:
79     - the upper bits of the pool table indices are read (used as
80     extension file numbers for gig v3)
81    
82     * src/RIFF.cpp, src/RIFF.h:
83     - the file name is remembered in the RIFF::File object
84

111     (patch by Andreas Persson)
112 schoenebeck 317 - added some file format compatibility checks
113 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

163 schoenebeck 196
164     * packaging changes:
165     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

174 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
175     (patch by Andreas Persson)
176 schoenebeck 231 - denormals are filtered from the velocity to volume tables
177 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
178     trigger dimension, no bit range check for dimensions of split type
179     'split_type_bit')
180 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from

182 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
183 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
184 schoenebeck 231
185 schoenebeck 220 * src/gigextract.cpp:
186     - added support for libsndfile (if libaudiofile and libsndfile are

188    
189 schoenebeck 229 * src/gigdump.cpp:
190     - added printout for dimension informations (amount, type, bits, zones)
191 schoenebeck 231 - added printout for velocity response curve parameters

197 capela 168 Version 0.7.1 (2 Jul 2004)
198    
199     * packaging changes:
200 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
201     Redhat packages
202 capela 168 - header files included on installation.
203     - autotools-generated files removed from CVS repository.
204 schoenebeck 186 - added support for generating Debian packages
205     - version of shared library can be set in configure.in
206    
207 schoenebeck 58 Version 0.7.0 (3 May 2004)
208    
209     * general changes:
210     - various big endian specific corrections
211     (successfully tested now on PPC)
212     - minor adjustments to avoid compile errors on some systems
213     (using now pow() instead of powl() and --pedantic g++ compiler switch)
214     - libtoolized the library
215     - added man pages for the command line tools
216     (gigextract, gigdump, dlsdump, rifftree)
217    
218     * src/gig.cpp, src/gig.h:
219     - fixed bug in decompression algorithm which caused it not to detect
220     the end of a stream
221     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
222     takes the MIDI key velocity value as an argument and returns the
223     appropriate volume factor (0.0 ... 1.0) for the sample to be played
224     back, the velocity curve transformation functions used for this are
225     only an approximation so far
226     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
227     'Sample::LoopSize' which reflected wrong values
228     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
229     measured in sample points instead of byte offset
230     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
231     'Sample::FineTune'
232     - added class attribute 'Sample::LoopSize'
233     - added method GetInstrument(uint index) to class 'File'
234     - added ReadAndLoop() method to class 'Sample' which is an extension to
235     the normal Read() method to honor the sample's looping information
236     while streaming from disk
237     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
238     'eg2_ctrl_t': replaced this huge enumeration by a structure which
239     reflects the MIDI controller number in case of an ordinary control
240     change controller (this saves a huge switch-case block in the
241     application of the library user)
242     - renamed following attributes in class 'DimensionRegion':
243     'AttenuationContol' -> 'AttenuationController',
244     'InvertAttenuationControl' -> 'InvertAttenuationController',
245     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
246     - minor fix in API documentation for method GetVelocityAttenuation() in
247     class 'DimensionRegion'
248    
249     * src/RIFF.cpp, src/RIFF.h:
250     - added additional API documentation
251     - minor fix in Chunk::Read() method (only a minor efficiency issue)
252    
253     * src/gigdump.cpp:
254     - added printout of samples' looping informations
255    
256 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
257    
258     * initial release
