12        - bugfix: GetPan always returned -1, 0 or 1
13    
14      * src/gig.cpp:
15        - bugfix: VCF velocity dynamic range and VCF velocity curve
16          weren't saved correctly
17        - implemented File::AddDuplicateInstrument()
18        - bugfix: negative EG3 depth values were not correctly parsed or
19          saved
20    
21      * src/DLS.cpp, src/DLS.h:
22        - added new method File::GetFileName()
23        - fixed minor "memory leak on exception" bug found with cppcheck
24        - added new method File::GetExtensionFile(int index)
25    
26      * src/RIFF.cpp, src/RIFF.h:
27        - bugfix: avoid calling read() with count 0 when writing a file,
28          as this may hang on some systems
29        - fixed memory leak and memory handling errors when file loading
30          fails
31    
32    Version 3.3.0 (30 Jul 2009)
33

35        - fixed compilation with gcc 4.3
36        - fixes for building with Visual C++
37        - minor fix in configure for building DLL on Windows
38    
39      * src/gig.cpp, src/gig.h:
40        - added partial support for MIDI rules, only the Controller
41          Triggered rule is supported so far
42        - bugfix: removed another iterator invalidation in DeleteSample
43        - bugfix in Sample::LoadSampleData*(): reset sample read position to
44          sample start before trying to (re)load sample data from file (#82)
45        - bugfix: EG3 depth parameter was not saved correctly
46        - fixed crash which occured when streaming a gig sample with

48    
49      * src/RIFF.cpp, src/RIFF.h:
50        - bugfix: saving to the same file after the file size had been
51          increased made the file corrupt (#82)

53          is not written physically yet (#82)
54        - bugfix: saving to the same file after the file size had been
55          decreased sometimes also made the file corrupt!
56        - bugfix: undefined behavior (e.g. endless loop) when opening zero
57          length files, now throws a RIFF::Exception instead (fixes bug #121)
58        - bugfix: destructor for base class RIFF::Chunk accessed members
59          of derived class RIFF::File, which is bad, and caused crashes
60          when using Visual C++
61        - bugfix: files that contain zero length RIFF lists were not read
62          correctly (fixes #127) (bug was introduced 2009-03-13)
63    
64    Version 3.2.1 (5 Dec 2007)
65    
66      * src/RIFF.cpp, src/RIFF.h:
67        - avoid Windows to perform unnecessary file stream caching which would
68          decrease disk streaming performance on Windows systems otherwise
69    
70      * src/gig.cpp, src/gig.h:
71        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
72          applications to retrieve very superficial informations like amount of
73          instruments and their names in a very fast way
74    
75    Version 3.2.0 (14 Oct 2007)
76    
77      * packaging changes:
78        - added Mac OSX XCode project files (patch by Toshi Nagata)

80          the version info from configure.in
81        - the configure script can now be used in Windows with MSYS
82        - added a mainpage for the Doxygen API documentation
83    
84      * src/DLS.cpp, src/DLS.h:
85        - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
86        - fixed write support for big-endian systems
87        - improved handling of fixed length info strings - separate default
88          lengths can be specified for each INFO chunk
89        - added Resource::GenerateDLSID function
90        - write support fix: allow regions without mapped samples
91        - added method SetKeyRange() to the Region class which should be used
92          instead of setting the KeyRange member variable directly
93        - MoveRegion() method of Region class is now private
94        - added SetGain() method to Sampler class
95        - fixed crash when saving a file after a sample loop was added
96    
97      * src/gig.cpp, src/gig.h:
98        - fixed segmentation fault in the gig::File destructor sequence which
99          happened when gig::Group informations were accessed before
100        - fixed write support for big-endian systems
101        - defined lengths of a fixed set of info strings. These strings
102          are saved when the file is written, even if they are empty.
103        - added missing parameter initalizations in sample, region and
104          instrument constructors
105        - clear unused fields when saving samples and regions
106        - fixed write support bugs: v3 dimension limits and chunksize
107          weren't saved, leverage controller of type controlchange
108          couldn't be saved, group name list chunk was placed wrong,
109          dimension region chunks also placed wrong
110        - added initialization of some fixed info strings in file and
111          instrument
112        - write support: files created by libgig will now have the RIFF
113          chunks in correct order
114        - write support: two previously unknown fields in dimension
115          definition are now saved
116        - added constants for gig file versions
117        - write support: the 3crc and einf chunks are now created or
118          updated when a file is saved (3crc contains sample checksums,
119          einf contains file statistics)
120        - write support: DLSID is now generated on the file and the
121          instruments
122        - write support: improved the default values for dimension region
123          parameters
124        - more write support fixes: crossfade parameters were not saved,
125          v3 dimension limits were not correctly initialized and saved
126          when dimensions were added or deleted, v3 wave pool offsets were
127          not saved correctly
128        - write support: 24 bit samples can now be written
129        - write support: version 3 is now the default for new files
130        - more write support fixes: the 3ewg chunk is now bigger for v3,
131          dimension regions without mapped samples are now allowed, 3gnl
132          list in v3 files now always has 128 entries, several parameters
133          where incorrectly saved due to an operator precedence mistake
134        - DeleteSample now removes all references to the deleted sample
135        - AddDimension now copies all parameters from existing dimension
136          regions and also makes sure that the samplechannel dimension is
137          placed first in the list of dimensions.
138        - added method GetParent() to class 'DimensionRegion', which returns its
139          parent Region
140        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
141          unused areas
142        - added various setter methods to DimensionRegion class which take care
143          of updating lookup tables / caches.
144    
145      * src/RIFF.cpp, src/RIFF.h:
146        - added File::SetByteOrder method
147        - Windows fix: saving a new file didn't work
148    
149      * src/gigdump.cpp:
150        - added some missing dimension strings

174      - fixed constructor for Region, which did not initialize correctly      - fixed constructor for Region, which did not initialize correctly
175        when used from Instrument::AddRegion        when used from Instrument::AddRegion
176        - when saving, override the gig::Regions sample reference simply by
177          the region's first dimension region's sample (avoids an exception
178          when trying to save a new instrument)
179        - fixed AddDimension() method which did not fill out all mandatory
180          dimension definition fields
181
