1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3    * src/gig.cpp, src/gig.h:    * src/gig.cpp, src/gig.h:
4        - added partial support for MIDI rules, only the Controller
5          Triggered rule is supported so far
6        - bugfix: removed another iterator invalidation in DeleteSample
7    
8      * src/RIFF.cpp, src/RIFF.h:
9        - bugfix: saving to the same file after the file size had been
10          increased made the file corrupt (#82)
11    
12    Version 3.2.1 (5 Dec 2007)
13    
14      * src/RIFF.cpp, src/RIFF.h:
15        - avoid Windows to perform unnecessary file stream caching which would
16          decrease disk streaming performance on Windows systems otherwise
17    
18      * src/gig.cpp, src/gig.h:
19        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
20          applications to retrieve very superficial informations like amount of
21          instruments and their names in a very fast way
22    
23    Version 3.2.0 (14 Oct 2007)
24    
25      * packaging changes:
26        - added Mac OSX XCode project files (patch by Toshi Nagata)
27        - Dev-C++ (win32) project file is automatically updated with
28          the version info from configure.in
29        - the configure script can now be used in Windows with MSYS
30        - added a mainpage for the Doxygen API documentation
31    
32      * src/DLS.cpp, src/DLS.h:
33        - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
34        - fixed write support for big-endian systems
35        - improved handling of fixed length info strings - separate default
36          lengths can be specified for each INFO chunk
37        - added Resource::GenerateDLSID function
38        - write support fix: allow regions without mapped samples
39        - added method SetKeyRange() to the Region class which should be used
40          instead of setting the KeyRange member variable directly
41        - MoveRegion() method of Region class is now private
42        - added SetGain() method to Sampler class
43        - fixed crash when saving a file after a sample loop was added
44    
45      * src/gig.cpp, src/gig.h:
46        - fixed segmentation fault in the gig::File destructor sequence which
47          happened when gig::Group informations were accessed before
48        - fixed write support for big-endian systems
49        - defined lengths of a fixed set of info strings. These strings
50          are saved when the file is written, even if they are empty.
51        - added missing parameter initalizations in sample, region and
52          instrument constructors
53        - clear unused fields when saving samples and regions
54        - fixed write support bugs: v3 dimension limits and chunksize
55          weren't saved, leverage controller of type controlchange
56          couldn't be saved, group name list chunk was placed wrong,
57          dimension region chunks also placed wrong
58        - added initialization of some fixed info strings in file and
59          instrument
60        - write support: files created by libgig will now have the RIFF
61          chunks in correct order
62        - write support: two previously unknown fields in dimension
63          definition are now saved
64        - added constants for gig file versions
65        - write support: the 3crc and einf chunks are now created or
66          updated when a file is saved (3crc contains sample checksums,
67          einf contains file statistics)
68        - write support: DLSID is now generated on the file and the
69          instruments
70        - write support: improved the default values for dimension region
71          parameters
72        - more write support fixes: crossfade parameters were not saved,
73          v3 dimension limits were not correctly initialized and saved
74          when dimensions were added or deleted, v3 wave pool offsets were
75          not saved correctly
76        - write support: 24 bit samples can now be written
77        - write support: version 3 is now the default for new files
78        - more write support fixes: the 3ewg chunk is now bigger for v3,
79          dimension regions without mapped samples are now allowed, 3gnl
80          list in v3 files now always has 128 entries, several parameters
81          where incorrectly saved due to an operator precedence mistake
82        - DeleteSample now removes all references to the deleted sample
83        - AddDimension now copies all parameters from existing dimension
84          regions and also makes sure that the samplechannel dimension is
85          placed first in the list of dimensions.
86        - added method GetParent() to class 'DimensionRegion', which returns its
87          parent Region
88        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
89          unused areas
90        - added various setter methods to DimensionRegion class which take care
91          of updating lookup tables / caches.
92    
93      * src/RIFF.cpp, src/RIFF.h:
94        - added File::SetByteOrder method
95        - Windows fix: saving a new file didn't work
96    
97      * src/gigdump.cpp:
98        - added some missing dimension strings
99    
100    Version 3.1.1 (24 Mar 2007)
101    
102      * packaging changes:
103        - ported to Windows using native Windows functions for file IO
104          (provided Dev-C++ + mingw project file)
105        - only export relevant files to Doxygen API documentation
106    
107      * src/gig.cpp, src/gig.h:
108        - custom velocity splits now works for gig v3 files too
109        - added support for custom splits points for other dimensions than
110          velocity (gig v3 feature)
111        - added "smart midi" and "round robin keyboard" dimensions
112        - added new method File::DeleteGroupOnly() which only deletes the given
113          group but moves all its members to another group, the other method,
114          that is File::DeleteGroup() now removes not just the group, but also
115          all the samples that belong to that group
116        - fixed crash which occured on interfering File::DeleteSample() and
117          File::GetNextSample() calls (due to iterator invalidation)
118        - fixed group names which were not saved
119        - fixed group destructor which did not remove the RIFF chunk associated
120          with the group
121        - added Instrument::MoveRegion method
122        - fixed constructor for Region, which did not initialize correctly
123          when used from Instrument::AddRegion
124        - when saving, override the gig::Regions sample reference simply by
125          the region's first dimension region's sample (avoids an exception
126          when trying to save a new instrument)
127        - fixed AddDimension() method which did not fill out all mandatory
128          dimension definition fields
129    
130      * src/DLS.cpp, src/DLS.h:
131        - added Instrument::MoveRegion method
132        - fixed software info field which was wrongly stored on instruments,
133          causing an exception when trying to save a new instrument
134    
135      * src/RIFF.cpp, src/RIFF.h:
136        - fixed RIFF::Chunk destructor which did not unregister previously
137          resized chunks, leading to a "zero size chunk" exception when
138          File::Save() was called
139        - added List::MoveSubChunk method
140

151        - sample loop parameters are now taken from the DimensionRegion
152          instead of the wave chunk
153        - keyswitching dimension is changed from split type "normal" to
154          "bit"
155        - real support for 24 bit samples - samples are not truncated to
156          16 bits anymore
157        - support for reading of ".art" files. (Merging of .art and .gig

188    
189      * src/gig.cpp, src/gig.h:

206          resize and write operations in one rush
207    
208      * src/gigdump.cpp:
