File size: 9737 byte(s)
* src/gig.cpp, src/gig.h:
  - added write support (highly experimental)
  - removed unnecessary definitions from header file
* src/DLS.cpp:
  - try to load instruments/samples before adding a new instrument/sample

1 persson 773 Version CVS HEAD (?)
2    
3 schoenebeck 780 * general changes:
4 schoenebeck 809 - added write support (that is for creating and modifying RIFF, DLS and
5     gig files)
6     - loading DLS and gig files is now much more permissive, DLS and gig
7     files are now loaded even if mandatory RIFF chunks are missing
8 schoenebeck 780
9 persson 773 * src/gig.cpp, src/gig.h:
10     - fixed the GetVelocityCutoff function, it wasn't always using the
11     VCFVelocityScale parameter when no cutoff controller was defined
12 persson 774 - support for the gig v3 feature to have a number of dimension
13     splits not equal to a power of two
14 schoenebeck 809 - added write support (highly experimental)
15 persson 773
16 schoenebeck 800 * src/DLS.cpp, src/DLS.h:
17     - fixed loading of Articulation Connections (<artl> list chunks were
18     seeked instead of ordinary <artl> data chunks)
19     - added write support (highly experimental)
20    
21     * src/RIFF.cpp, src/RIFF.h:
22     - added write support
23     - Chunk::LoadChunkData() can now be called again to resize the buffer
24     after a Chunk::Resize() and before the File::Save() call to allow
25     placing the new data in the chunk's write buffer and perform the
26     resize and write operations in one rush
27    
28 schoenebeck 809 * src/gigdump.cpp:
29     - fixed to show the correct amount of dimension regions instead of 32
30     (patch by James Wylder)
31    
32 schoenebeck 804 * src/dlsdump.cpp:
33     - show for every region the name of the referenced sample
34     - show file name in quotation marks
35    
36 schoenebeck 732 Version 2.0.2 (15 Aug 2005)
37 schoenebeck 652
38     * packaging changes:
39     - require automake (>= 1.5) for 'make -f Makefile.cvs'
40     (mandatory for 'dist-bzip2' automake option)
41    
42 persson 666 * src/gig.cpp, src/gig.h:
43     - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
44     the extension files are read automatically when the samples are
45     loaded
46 persson 695 - fixed the 24 bit decompression, the result should now be exact
47     instead of an approximation
48 persson 728 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
49     function to DimensionRegion
50 persson 666
51     * src/DLS.cpp, src/DLS.h:

53     extension file numbers for gig v3)
54    
55     * src/RIFF.cpp, src/RIFF.h:
56     - the file name is remembered in the RIFF::File object

84     (patch by Andreas Persson)
85 schoenebeck 317 - added some file format compatibility checks
86 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

136 schoenebeck 196
137     * packaging changes:
138     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
139     'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix

141     SuSE and Fedora)
142     - fixed generation of Doxygen API documentation (now also included in

147 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
148     (patch by Andreas Persson)
149 schoenebeck 231 - denormals are filtered from the velocity to volume tables
150 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
151     trigger dimension, no bit range check for dimensions of split type
152     'split_type_bit')
153 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
154     signed 7 bit to signed 8 bit)
155 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
156 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
157 schoenebeck 231
158 schoenebeck 220 * src/gigextract.cpp:
159     - added support for libsndfile (if libaudiofile and libsndfile are
160     available then libsndfile is preferred)
161    
162 schoenebeck 229 * src/gigdump.cpp:
163     - added printout for dimension informations (amount, type, bits, zones)
164 schoenebeck 231 - added printout for velocity response curve parameters

169 schoenebeck 229
170 capela 168 Version 0.7.1 (2 Jul 2004)
171    
172     * packaging changes:
173 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
174     Redhat packages
175 capela 168 - header files included on installation.
176     - autotools-generated files removed from CVS repository.
177 schoenebeck 186 - added support for generating Debian packages
178     - version of shared library can be set in configure.in
179    
180 schoenebeck 58 Version 0.7.0 (3 May 2004)
181    
182     * general changes:
183     - various big endian specific corrections
184     (successfully tested now on PPC)
185     - minor adjustments to avoid compile errors on some systems
186     (using now pow() instead of powl() and --pedantic g++ compiler switch)
187     - libtoolized the library
188     - added man pages for the command line tools
189     (gigextract, gigdump, dlsdump, rifftree)
190    
191     * src/gig.cpp, src/gig.h:
192     - fixed bug in decompression algorithm which caused it not to detect
193     the end of a stream
194     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
195     takes the MIDI key velocity value as an argument and returns the
196     appropriate volume factor (0.0 ... 1.0) for the sample to be played
197     back, the velocity curve transformation functions used for this are
198     only an approximation so far
199     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
200     'Sample::LoopSize' which reflected wrong values
201     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
202     measured in sample points instead of byte offset
203     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
204     'Sample::FineTune'
205     - added class attribute 'Sample::LoopSize'
206     - added method GetInstrument(uint index) to class 'File'
207     - added ReadAndLoop() method to class 'Sample' which is an extension to
208     the normal Read() method to honor the sample's looping information
209     while streaming from disk
210     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
211     'eg2_ctrl_t': replaced this huge enumeration by a structure which
212     reflects the MIDI controller number in case of an ordinary control
213     change controller (this saves a huge switch-case block in the
214     application of the library user)
215     - renamed following attributes in class 'DimensionRegion':
216     'AttenuationContol' -> 'AttenuationController',
217     'InvertAttenuationControl' -> 'InvertAttenuationController',
218     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
219     - minor fix in API documentation for method GetVelocityAttenuation() in
220     class 'DimensionRegion'
221    
222     * src/RIFF.cpp, src/RIFF.h:
223     - added additional API documentation
224     - minor fix in Chunk::Read() method (only a minor efficiency issue)
225    
226     * src/gigdump.cpp:
227     - added printout of samples' looping informations
228    
229 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
230    
231     * initial release
