* added CPPUnit test cases (at the moment primarily for automatic check
  of Gigasampler 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 858
20 persson 902 * src/DLS.cpp:
21     - support for reading of ".art" files
22    
23     * src/gigextract.cpp:
24     - real support for 24 bit samples
25    
26 schoenebeck 916 * src/gigdump.cpp:
27     - print global file informations
28    
29 schoenebeck 917 * general changes:
30     - added CPPUnit test cases (at the moment primarily for automatic check
31     of Gigasampler write support)
32    
33 schoenebeck 854 Version 3.0.0 (28 Apr 2006)
34 persson 773
35 schoenebeck 780 * general changes:
36 schoenebeck 809 - added write support (that is for creating and modifying RIFF, DLS and
37     gig files)
38     - loading DLS and gig files is now much more permissive, DLS and gig
39     files are now loaded even if mandatory RIFF chunks are missing
40 persson 834 - fixed some memory management errors, one of them was causing a
41     crash when a multi-file gig was deallocated
42 schoenebeck 780
43 persson 773 * src/gig.cpp, src/gig.h:
44     - fixed the GetVelocityCutoff function, it wasn't always using the
45     VCFVelocityScale parameter when no cutoff controller was defined
46 persson 774 - support for the gig v3 feature to have a number of dimension
47     splits not equal to a power of two
48 schoenebeck 809 - added write support (highly experimental)
49 persson 773
50 schoenebeck 800 * src/DLS.cpp, src/DLS.h:
51     - fixed loading of Articulation Connections (<artl> list chunks were
52     seeked instead of ordinary <artl> data chunks)
53     - added write support (highly experimental)
54    
55     * src/RIFF.cpp, src/RIFF.h:
56     - added write support
57     - Chunk::LoadChunkData() can now be called again to resize the buffer
58     after a Chunk::Resize() and before the File::Save() call to allow
59     placing the new data in the chunk's write buffer and perform the
60     resize and write operations in one rush
61    
62 schoenebeck 809 * src/gigdump.cpp:
63     - fixed to show the correct amount of dimension regions instead of 32
64     (patch by James Wylder)
65    
66 schoenebeck 804 * src/dlsdump.cpp:
67     - show for every region the name of the referenced sample

83     function to DimensionRegion
84 persson 666
85     * src/DLS.cpp, src/DLS.h:

87     extension file numbers for gig v3)
88    
89     * src/RIFF.cpp, src/RIFF.h:
90     - the file name is remembered in the RIFF::File object

170 schoenebeck 196
171     * packaging changes:
172     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
173     'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix

181 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
182     (patch by Andreas Persson)
183 schoenebeck 231 - denormals are filtered from the velocity to volume tables
184 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
185     trigger dimension, no bit range check for dimensions of split type
186     'split_type_bit')
187 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
188     signed 7 bit to signed 8 bit)
189 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
190 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
191 schoenebeck 231
192 schoenebeck 220 * src/gigextract.cpp:
193     - added support for libsndfile (if libaudiofile and libsndfile are
194     available then libsndfile is preferred)
195    
196 schoenebeck 229 * src/gigdump.cpp:
197     - added printout for dimension informations (amount, type, bits, zones)
198 schoenebeck 231 - added printout for velocity response curve parameters

203 schoenebeck 229
204 capela 168 Version 0.7.1 (2 Jul 2004)
205    
206     * packaging changes:
207 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
208     Redhat packages
209 capela 168 - header files included on installation.
210     - autotools-generated files removed from CVS repository.
211 schoenebeck 186 - added support for generating Debian packages
212     - version of shared library can be set in configure.in
213    
214 schoenebeck 58 Version 0.7.0 (3 May 2004)
215    
216     * general changes:
217     - various big endian specific corrections
218     (successfully tested now on PPC)
219     - minor adjustments to avoid compile errors on some systems
220     (using now pow() instead of powl() and --pedantic g++ compiler switch)
221     - libtoolized the library
222     - added man pages for the command line tools
223     (gigextract, gigdump, dlsdump, rifftree)
224    
225     * src/gig.cpp, src/gig.h:
226     - fixed bug in decompression algorithm which caused it not to detect
227     the end of a stream
228     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
229     takes the MIDI key velocity value as an argument and returns the
230     appropriate volume factor (0.0 ... 1.0) for the sample to be played
231     back, the velocity curve transformation functions used for this are
232     only an approximation so far
233     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
234     'Sample::LoopSize' which reflected wrong values
235     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
236     measured in sample points instead of byte offset
237     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
238     'Sample::FineTune'
239     - added class attribute 'Sample::LoopSize'
240     - added method GetInstrument(uint index) to class 'File'
241     - added ReadAndLoop() method to class 'Sample' which is an extension to
242     the normal Read() method to honor the sample's looping information
243     while streaming from disk
244     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
245     'eg2_ctrl_t': replaced this huge enumeration by a structure which
246     reflects the MIDI controller number in case of an ordinary control
247     change controller (this saves a huge switch-case block in the
248     application of the library user)
249     - renamed following attributes in class 'DimensionRegion':
250     'AttenuationContol' -> 'AttenuationController',
251     'InvertAttenuationControl' -> 'InvertAttenuationController',
252     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
253     - minor fix in API documentation for method GetVelocityAttenuation() in
254     class 'DimensionRegion'
255    
256     * src/RIFF.cpp, src/RIFF.h:
257     - added additional API documentation
258     - minor fix in Chunk::Read() method (only a minor efficiency issue)
259    
260     * src/gigdump.cpp:
261     - added printout of samples' looping informations
262    
263 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
264    
265     * initial release
