# Line 1  Line 1 
1    Version CVS HEAD (?)
2    
3      * packaging changes:
4        - added Mac OSX XCode project files (patch by Toshi Nagata)
5    
6      * src/DLS.cpp, src/DLS.h:
7        - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
8        - fixed write support for big-endian systems
9        - improved handling of fixed length info strings - separate default
10          lengths can be specified for each INFO chunk
11    
12      * src/gig.cpp, src/gig.h:
13        - fixed segmentation fault in the gig::File destructor sequence which
14          happened when gig::Group informations were accessed before
15        - fixed write support for big-endian systems
16        - defined lengths of a fixed set of info strings. These strings
17          are saved when the file is written, even if they are empty.
18        - added missing parameter initalizations in sample, region and
19          instrument constructors
20        - clear unused fields when saving samples and regions
21        - fixed write support bugs: v3 dimension limits and chunksize
22          weren't saved, leverage controller of type controlchange
23          couldn't be saved, group name list chunk was placed wrong
24        - added initialization of some fixed info strings in file and
25          instrument
26    
27      * src/RIFF.cpp, src/RIFF.h:
28        - added File::SetByteOrder method
29    
30    Version 3.1.1 (24 Mar 2007)
31    
32      * packaging changes:
33        - ported to Windows using native Windows functions for file IO
34          (provided Dev-C++ + mingw project file)
35        - only export relevant files to Doxygen API documentation
36    
37      * src/gig.cpp, src/gig.h:
38        - custom velocity splits now works for gig v3 files too
39        - added support for custom splits points for other dimensions than
40          velocity (gig v3 feature)
41        - added "smart midi" and "round robin keyboard" dimensions
42        - added new method File::DeleteGroupOnly() which only deletes the given
43          group but moves all its members to another group, the other method,
44          that is File::DeleteGroup() now removes not just the group, but also
45          all the samples that belong to that group
46        - fixed crash which occured on interfering File::DeleteSample() and
47          File::GetNextSample() calls (due to iterator invalidation)
48        - fixed group names which were not saved
49        - fixed group destructor which did not remove the RIFF chunk associated
50          with the group
51        - added Instrument::MoveRegion method
52        - fixed constructor for Region, which did not initialize correctly
53          when used from Instrument::AddRegion
54        - when saving, override the gig::Regions sample reference simply by
55          the region's first dimension region's sample (avoids an exception
56          when trying to save a new instrument)
57        - fixed AddDimension() method which did not fill out all mandatory
58          dimension definition fields
59    
60      * src/DLS.cpp, src/DLS.h:
61        - added Instrument::MoveRegion method
62        - fixed software info field which was wrongly stored on instruments,
63          causing an exception when trying to save a new instrument
64    
65      * src/RIFF.cpp, src/RIFF.h:
66        - fixed RIFF::Chunk destructor which did not unregister previously
67          resized chunks, leading to a "zero size chunk" exception when
68          File::Save() was called
69        - added List::MoveSubChunk method
70    
71    Version 3.1.0 (24 Nov 2006)
72    
73      * packaging changes:
74        - changed deprecated copyright attribute to license;
75          added ldconfig to post-(un)install steps on libgig.spec (RPM)
76    
77      * src/gig.cpp, src/gig.h:
78        - added support for more than one set of custom velocity splits
79          inside a region (for example different velocity split levels for
80          pedal up and pedal down)
81        - sample loop parameters are now taken from the DimensionRegion
82          instead of the wave chunk
83        - keyswitching dimension is changed from split type "normal" to
84          "bit"
85        - real support for 24 bit samples - samples are not truncated to
86          16 bits anymore
87        - support for reading of ".art" files. (Merging of .art and .gig
88          files are not implemented yet.)
89        - several fixes for the write support
90        - support for sample groups added
91    
92      * src/DLS.cpp, src/DLS.h:
93        - support for reading of ".art" files

95          Jeremy Kerr)
96        - several fixes for the write support
97    
98      * src/gigextract.cpp:
99        - real support for 24 bit samples

107          of Gigasampler write support)
108    
109    Version 3.0.0 (28 Apr 2006)
110    
111      * general changes:
112        - added write support (that is for creating and modifying RIFF, DLS and
113          gig files)
114        - loading DLS and gig files is now much more permissive, DLS and gig
115          files are now loaded even if mandatory RIFF chunks are missing
116        - fixed some memory management errors, one of them was causing a
117          crash when a multi-file gig was deallocated
118    
119      * src/gig.cpp, src/gig.h:
120        - fixed the GetVelocityCutoff function, it wasn't always using the
121          VCFVelocityScale parameter when no cutoff controller was defined
122        - support for the gig v3 feature to have a number of dimension
123          splits not equal to a power of two

125    
126      * src/DLS.cpp, src/DLS.h:
127        - fixed loading of Articulation Connections (<artl> list chunks were
128          seeked instead of ordinary <artl> data chunks)
129        - added write support (highly experimental)
130    
131      * src/RIFF.cpp, src/RIFF.h:
132        - added write support
133        - Chunk::LoadChunkData() can now be called again to resize the buffer
134          after a Chunk::Resize() and before the File::Save() call to allow
135          placing the new data in the chunk's write buffer and perform the
136          resize and write operations in one rush
137    
138      * src/gigdump.cpp:
139        - fixed to show the correct amount of dimension regions instead of 32
140          (patch by James Wylder)
141    
142      * src/dlsdump.cpp:

147    
148      * packaging changes:
149        - require automake (>= 1.5) for 'make -f Makefile.cvs'
150          (mandatory for 'dist-bzip2' automake option)
151    
152      * src/gig.cpp, src/gig.h:
153        - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
154          the extension files are read automatically when the samples are
155          loaded
156        - fixed the 24 bit decompression, the result should now be exact
157          instead of an approximation
158        - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
159          function to DimensionRegion
160

163          extension file numbers for gig v3)
164    
165      * src/RIFF.cpp, src/RIFF.h:
166        - the file name is remembered in the RIFF::File object

194          (patch by Andreas Persson)
195        - added some file format compatibility checks
196        - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
197          never used, because the necessary check was made before

243          used libgig version
244    
245    Version 1.0.0 (26 Nov 2004)
246    
247      * packaging changes:
248        - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
249          'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
250        - fixed man pages automake install rule (which didn't work on Mandrake,
251          SuSE and Fedora)
