3    * packaging changes:    * 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    Version 3.1.1 (24 Mar 2007)
28    
29      * packaging changes:
30        - ported to Windows using native Windows functions for file IO
31          (provided Dev-C++ + mingw project file)
32        - only export relevant files to Doxygen API documentation
33    
34      * src/gig.cpp, src/gig.h:
35        - custom velocity splits now works for gig v3 files too
36        - added support for custom splits points for other dimensions than
37          velocity (gig v3 feature)
38        - added "smart midi" and "round robin keyboard" dimensions
39        - added new method File::DeleteGroupOnly() which only deletes the given
40          group but moves all its members to another group, the other method,
41          that is File::DeleteGroup() now removes not just the group, but also
42          all the samples that belong to that group
43        - fixed crash which occured on interfering File::DeleteSample() and
44          File::GetNextSample() calls (due to iterator invalidation)
45        - fixed group names which were not saved
46        - fixed group destructor which did not remove the RIFF chunk associated
47          with the group
48        - added Instrument::MoveRegion method
49        - fixed constructor for Region, which did not initialize correctly
50          when used from Instrument::AddRegion
51        - when saving, override the gig::Regions sample reference simply by
52          the region's first dimension region's sample (avoids an exception
53          when trying to save a new instrument)
54        - fixed AddDimension() method which did not fill out all mandatory
55          dimension definition fields
56    
57      * src/DLS.cpp, src/DLS.h:
58        - added Instrument::MoveRegion method
59        - fixed software info field which was wrongly stored on instruments,
60          causing an exception when trying to save a new instrument
61    
62      * src/RIFF.cpp, src/RIFF.h:
63        - fixed RIFF::Chunk destructor which did not unregister previously
64          resized chunks, leading to a "zero size chunk" exception when
65          File::Save() was called
66        - added List::MoveSubChunk method
67    
68    Version 3.1.0 (24 Nov 2006)
69    
70      * packaging changes:
71        - changed deprecated copyright attribute to license;
72          added ldconfig to post-(un)install steps on libgig.spec (RPM)
73    
74      * src/gig.cpp, src/gig.h:
75        - added support for more than one set of custom velocity splits
76          inside a region (for example different velocity split levels for
77          pedal up and pedal down)
78        - sample loop parameters are now taken from the DimensionRegion
79          instead of the wave chunk
80        - keyswitching dimension is changed from split type "normal" to
81          "bit"
82        - real support for 24 bit samples - samples are not truncated to
83          16 bits anymore
84        - support for reading of ".art" files. (Merging of .art and .gig
85          files are not implemented yet.)
86        - several fixes for the write support
87        - support for sample groups added
88    
89      * src/DLS.cpp, src/DLS.h:

94    
95      * src/gigextract.cpp:
96        - real support for 24 bit samples

105    
106    Version 3.0.0 (28 Apr 2006)
107    
108      * general changes:
109        - added write support (that is for creating and modifying RIFF, DLS and
110          gig files)
111        - loading DLS and gig files is now much more permissive, DLS and gig
112          files are now loaded even if mandatory RIFF chunks are missing
113        - fixed some memory management errors, one of them was causing a
114          crash when a multi-file gig was deallocated
115    
116      * src/gig.cpp, src/gig.h:
117        - fixed the GetVelocityCutoff function, it wasn't always using the
118          VCFVelocityScale parameter when no cutoff controller was defined

120          splits not equal to a power of two

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

150        - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
151          the extension files are read automatically when the samples are

154          instead of an approximation
155        - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
156          function to DimensionRegion
157

162      * src/RIFF.cpp, src/RIFF.h:
163        - the file name is remembered in the RIFF::File object
