# Line 1  Line 1 
1    Version CVS HEAD (?)
2    
3      * src/RIFF.cpp, src/RIFF.h:
4        - avoid Windows to perform unnecessary file stream caching which would
5          decrease disk streaming performance on Windows systems otherwise
6    
7    Version 3.2.0 (14 Oct 2007)
8    
9      * packaging changes:
10        - added Mac OSX XCode project files (patch by Toshi Nagata)
11        - Dev-C++ (win32) project file is automatically updated with
12          the version info from configure.in
13        - the configure script can now be used in Windows with MSYS
14        - added a mainpage for the Doxygen API documentation
15    
16      * src/DLS.cpp, src/DLS.h:
17        - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
18        - fixed write support for big-endian systems
19        - improved handling of fixed length info strings - separate default
20          lengths can be specified for each INFO chunk
21        - added Resource::GenerateDLSID function
22        - write support fix: allow regions without mapped samples
23        - added method SetKeyRange() to the Region class which should be used
24          instead of setting the KeyRange member variable directly
25        - MoveRegion() method of Region class is now private
26        - added SetGain() method to Sampler class
27        - fixed crash when saving a file after a sample loop was added
28    
29      * src/gig.cpp, src/gig.h:
30        - fixed segmentation fault in the gig::File destructor sequence which
31          happened when gig::Group informations were accessed before
32        - fixed write support for big-endian systems
33        - defined lengths of a fixed set of info strings. These strings
34          are saved when the file is written, even if they are empty.
35        - added missing parameter initalizations in sample, region and
36          instrument constructors
37        - clear unused fields when saving samples and regions
38        - fixed write support bugs: v3 dimension limits and chunksize
39          weren't saved, leverage controller of type controlchange
40          couldn't be saved, group name list chunk was placed wrong,
41          dimension region chunks also placed wrong
42        - added initialization of some fixed info strings in file and
43          instrument
44        - write support: files created by libgig will now have the RIFF
45          chunks in correct order
46        - write support: two previously unknown fields in dimension
47          definition are now saved
48        - added constants for gig file versions
49        - write support: the 3crc and einf chunks are now created or
50          updated when a file is saved (3crc contains sample checksums,
51          einf contains file statistics)
52        - write support: DLSID is now generated on the file and the
53          instruments
54        - write support: improved the default values for dimension region
55          parameters
56        - more write support fixes: crossfade parameters were not saved,
57          v3 dimension limits were not correctly initialized and saved
58          when dimensions were added or deleted, v3 wave pool offsets were
59          not saved correctly
60        - write support: 24 bit samples can now be written
61        - write support: version 3 is now the default for new files
62        - more write support fixes: the 3ewg chunk is now bigger for v3,
63          dimension regions without mapped samples are now allowed, 3gnl
64          list in v3 files now always has 128 entries, several parameters
65          where incorrectly saved due to an operator precedence mistake
66        - DeleteSample now removes all references to the deleted sample
67        - AddDimension now copies all parameters from existing dimension
68          regions and also makes sure that the samplechannel dimension is
69          placed first in the list of dimensions.
70        - added method GetParent() to class 'DimensionRegion', which returns its
71          parent Region
72        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
73          unused areas
74        - added various setter methods to DimensionRegion class which take care
75          of updating lookup tables / caches.
76    
77      * src/RIFF.cpp, src/RIFF.h:
78        - added File::SetByteOrder method
79        - Windows fix: saving a new file didn't work
80    
81      * src/gigdump.cpp:
82        - added some missing dimension strings
83    
84    Version 3.1.1 (24 Mar 2007)
85    
86      * packaging changes:
87        - ported to Windows using native Windows functions for file IO
88          (provided Dev-C++ + mingw project file)
89        - only export relevant files to Doxygen API documentation
90    
91      * src/gig.cpp, src/gig.h:
92        - custom velocity splits now works for gig v3 files too
93        - added support for custom splits points for other dimensions than
94          velocity (gig v3 feature)
95        - added "smart midi" and "round robin keyboard" dimensions
96        - added new method File::DeleteGroupOnly() which only deletes the given
97          group but moves all its members to another group, the other method,
98          that is File::DeleteGroup() now removes not just the group, but also
99          all the samples that belong to that group
100        - fixed crash which occured on interfering File::DeleteSample() and
101          File::GetNextSample() calls (due to iterator invalidation)
102        - fixed group names which were not saved
103        - fixed group destructor which did not remove the RIFF chunk associated
104          with the group
105        - added Instrument::MoveRegion method
106        - fixed constructor for Region, which did not initialize correctly
107          when used from Instrument::AddRegion
108        - when saving, override the gig::Regions sample reference simply by
109          the region's first dimension region's sample (avoids an exception
110          when trying to save a new instrument)
111        - fixed AddDimension() method which did not fill out all mandatory
112          dimension definition fields
113    
114      * src/DLS.cpp, src/DLS.h:
115        - added Instrument::MoveRegion method
116        - fixed software info field which was wrongly stored on instruments,
117          causing an exception when trying to save a new instrument
118    
119      * src/RIFF.cpp, src/RIFF.h:
120        - fixed RIFF::Chunk destructor which did not unregister previously
121          resized chunks, leading to a "zero size chunk" exception when
122          File::Save() was called
123        - added List::MoveSubChunk method
124    
125    Version 3.1.0 (24 Nov 2006)

135        - sample loop parameters are now taken from the DimensionRegion
136          instead of the wave chunk
137        - keyswitching dimension is changed from split type "normal" to
138          "bit"
139        - real support for 24 bit samples - samples are not truncated to
140          16 bits anymore
141        - support for reading of ".art" files. (Merging of .art and .gig
142          files are not implemented yet.)

171          crash when a multi-file gig was deallocated
172    
173      * src/gig.cpp, src/gig.h:

188          after a Chunk::Resize() and before the File::Save() call to allow
189          placing the new data in the chunk's write buffer and perform the
190          resize and write operations in one rush
191    
192      * src/gigdump.cpp:
193        - fixed to show the correct amount of dimension regions instead of 32
