* preparations for release 3.0.0

1 schoenebeck 854 Version 3.0.0 (28 Apr 2006)
2 persson 773
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 persson 834 - fixed some memory management errors, one of them was causing a
9     crash when a multi-file gig was deallocated
10 schoenebeck 780
11 persson 773 * src/gig.cpp, src/gig.h:
12     - fixed the GetVelocityCutoff function, it wasn't always using the
13     VCFVelocityScale parameter when no cutoff controller was defined
14 persson 774 - support for the gig v3 feature to have a number of dimension
15     splits not equal to a power of two
16 schoenebeck 809 - added write support (highly experimental)
17 persson 773
18 schoenebeck 800 * src/DLS.cpp, src/DLS.h:
19     - fixed loading of Articulation Connections (<artl> list chunks were
20     seeked instead of ordinary <artl> data chunks)
21     - added write support (highly experimental)
22    
23     * src/RIFF.cpp, src/RIFF.h:
24     - added write support
25     - Chunk::LoadChunkData() can now be called again to resize the buffer
26     after a Chunk::Resize() and before the File::Save() call to allow
27     placing the new data in the chunk's write buffer and perform the
28     resize and write operations in one rush
29    
30 schoenebeck 809 * src/gigdump.cpp:
31     - fixed to show the correct amount of dimension regions instead of 32
32     (patch by James Wylder)
33    
34 schoenebeck 804 * src/dlsdump.cpp:
35     - show for every region the name of the referenced sample
36     - show file name in quotation marks
37    
38 schoenebeck 732 Version 2.0.2 (15 Aug 2005)
39 schoenebeck 652
40     * packaging changes:
41     - require automake (>= 1.5) for 'make -f Makefile.cvs'
42     (mandatory for 'dist-bzip2' automake option)
43    
44 persson 666 * src/gig.cpp, src/gig.h:
45     - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
46     the extension files are read automatically when the samples are
47     loaded
48 persson 695 - fixed the 24 bit decompression, the result should now be exact
49     instead of an approximation
50 persson 728 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
51     function to DimensionRegion
52 persson 666
53     * src/DLS.cpp, src/DLS.h:
54     - the upper bits of the pool table indices are read (used as
55     extension file numbers for gig v3)
56    
57     * src/RIFF.cpp, src/RIFF.h:
58     - the file name is remembered in the RIFF::File object
59    
60 schoenebeck 632 Version 2.0.1 (12 Jun 2005)
61 schoenebeck 549
62 schoenebeck 634 * packaging changes:

75 schoenebeck 317
76 schoenebeck 383 * packaging changes:
77     - fixed conditional linkage of either libsndfile or libaudiofile

84 schoenebeck 347 truncated to 16 bit, up to 8 dimensions are read, additional
85     articulation informations are ignored at the moment
86     (patch by Andreas Persson)
87 schoenebeck 317 - added some file format compatibility checks
88 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
89     never used, because the necessary check was made before
90     initialization)

92     endian systems was interchanged)
93 schoenebeck 355 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

115     position within the body of the given list chunk
116 schoenebeck 518 - added functions libraryName() and libraryVersion()
117 schoenebeck 515

137 schoenebeck 315 Version 1.0.0 (26 Nov 2004)
138 schoenebeck 196
139     * packaging changes:
140     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
141     'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix

143     SuSE and Fedora)
144     - fixed generation of Doxygen API documentation (now also included in
145     RPM and Debian packages)
146 schoenebeck 196
147 schoenebeck 231 * src/gig.cpp, src/gig.h:
148     - fixed / improved accuracy of all three velocity to volume
149 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
150     (patch by Andreas Persson)
151 schoenebeck 231 - denormals are filtered from the velocity to volume tables
152 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
153     trigger dimension, no bit range check for dimensions of split type
154     'split_type_bit')
155 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
156     signed 7 bit to signed 8 bit)
157 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
158 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
159 schoenebeck 231
160 schoenebeck 220 * src/gigextract.cpp:
161     - added support for libsndfile (if libaudiofile and libsndfile are
162     available then libsndfile is preferred)
163    
164 schoenebeck 229 * src/gigdump.cpp:
165     - added printout for dimension informations (amount, type, bits, zones)
166 schoenebeck 231 - added printout for velocity response curve parameters
167 schoenebeck 235 - added printout for crossfade definitions
168 schoenebeck 269 - added printout for panorama value for each DimensionRegion
169 schoenebeck 282 - replaced printout of DLS Region layer by printout of amount of
170     Gigasampler layers
171 schoenebeck 229
172 capela 168 Version 0.7.1 (2 Jul 2004)
173    
174     * packaging changes:
175 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
176     Redhat packages
177 capela 168 - header files included on installation.
178     - autotools-generated files removed from CVS repository.
179 schoenebeck 186 - added support for generating Debian packages
180     - version of shared library can be set in configure.in
181    
182 schoenebeck 58 Version 0.7.0 (3 May 2004)
183    
184     * general changes:
185     - various big endian specific corrections
186     (successfully tested now on PPC)
187     - minor adjustments to avoid compile errors on some systems
188     (using now pow() instead of powl() and --pedantic g++ compiler switch)
189     - libtoolized the library
190     - added man pages for the command line tools
191     (gigextract, gigdump, dlsdump, rifftree)
192    
193     * src/gig.cpp, src/gig.h:
194     - fixed bug in decompression algorithm which caused it not to detect
195     the end of a stream
196     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
197     takes the MIDI key velocity value as an argument and returns the
198     appropriate volume factor (0.0 ... 1.0) for the sample to be played
199     back, the velocity curve transformation functions used for this are
200     only an approximation so far
201     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
202     'Sample::LoopSize' which reflected wrong values
203     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
204     measured in sample points instead of byte offset
205     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
206     'Sample::FineTune'
207     - added class attribute 'Sample::LoopSize'
208     - added method GetInstrument(uint index) to class 'File'
209     - added ReadAndLoop() method to class 'Sample' which is an extension to
210     the normal Read() method to honor the sample's looping information
211     while streaming from disk
212     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
213     'eg2_ctrl_t': replaced this huge enumeration by a structure which
214     reflects the MIDI controller number in case of an ordinary control
215     change controller (this saves a huge switch-case block in the
216     application of the library user)
217     - renamed following attributes in class 'DimensionRegion':
218     'AttenuationContol' -> 'AttenuationController',
219     'InvertAttenuationControl' -> 'InvertAttenuationController',
220     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
221     - minor fix in API documentation for method GetVelocityAttenuation() in
222     class 'DimensionRegion'
223    
224     * src/RIFF.cpp, src/RIFF.h:
225     - added additional API documentation
226     - minor fix in Chunk::Read() method (only a minor efficiency issue)
227    
228     * src/gigdump.cpp:
229     - added printout of samples' looping informations
230    
231 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
232    
233     * initial release
