# Line 1  Line 1 
1  Version CVS HEAD (?)  Version CVS HEAD (?)
2      * general changes:
3        - minor Makefile fix for parallel make
4    
5      * SoundFont file format
6        - initial implementation
7        - changed region lookup API to avoid malloc in RT threads
8    
9      * src/gig.cpp:
10        - bugfix: VCF velocity dynamic range and VCF velocity curve
11          weren't saved correctly
12    
13      * src/RIFF.cpp, src/RIFF.h:
14        - bugfix: avoid calling read() with count 0 when writing a file,
15          as this may hang on some systems
16    
17    Version 3.3.0 (30 Jul 2009)
18    
19      * general changes:
20        - fixed compilation with gcc 4.3
21        - fixes for building with Visual C++
22        - minor fix in configure for building DLL on Windows
23    
24      * src/gig.cpp, src/gig.h:
25        - added partial support for MIDI rules, only the Controller
26          Triggered rule is supported so far
27        - bugfix: removed another iterator invalidation in DeleteSample
28        - bugfix in Sample::LoadSampleData*(): reset sample read position to
29          sample start before trying to (re)load sample data from file (#82)
30        - bugfix: EG3 depth parameter was not saved correctly
31        - fixed crash which occured when streaming a gig sample with
32          bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
33    
34      * src/RIFF.cpp, src/RIFF.h:
35        - bugfix: saving to the same file after the file size had been
36          increased made the file corrupt (#82)
37        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
38          is not written physically yet (#82)
39        - bugfix: saving to the same file after the file size had been
40          decreased sometimes also made the file corrupt!
41        - bugfix: undefined behavior (e.g. endless loop) when opening zero
42          length files, now throws a RIFF::Exception instead (fixes bug #121)
43        - bugfix: destructor for base class RIFF::Chunk accessed members
44          of derived class RIFF::File, which is bad, and caused crashes
45          when using Visual C++
46        - bugfix: files that contain zero length RIFF lists were not read
47          correctly (fixes #127) (bug was introduced 2009-03-13)
48    
49    Version 3.2.1 (5 Dec 2007)
50    
51      * src/RIFF.cpp, src/RIFF.h:
52        - avoid Windows to perform unnecessary file stream caching which would
53          decrease disk streaming performance on Windows systems otherwise
54    
55      * src/gig.cpp, src/gig.h:
56        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
57          applications to retrieve very superficial informations like amount of
58          instruments and their names in a very fast way
59    
60    Version 3.2.0 (14 Oct 2007)
61    
62    * packaging changes:    * packaging changes:
63      - added Mac OSX XCode project files (patch by Toshi Nagata)      - added Mac OSX XCode project files (patch by Toshi Nagata)
64        - Dev-C++ (win32) project file is automatically updated with
65          the version info from configure.in
66        - the configure script can now be used in Windows with MSYS
67        - added a mainpage for the Doxygen API documentation
68    
69    * src/DLS.cpp, src/DLS.h:    * src/DLS.cpp, src/DLS.h:
70      - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods      - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
71      - fixed write support for big-endian systems      - fixed write support for big-endian systems
72        - improved handling of fixed length info strings - separate default
73          lengths can be specified for each INFO chunk
74        - added Resource::GenerateDLSID function
75        - write support fix: allow regions without mapped samples
76        - added method SetKeyRange() to the Region class which should be used
77          instead of setting the KeyRange member variable directly
78        - MoveRegion() method of Region class is now private
79        - added SetGain() method to Sampler class
80        - fixed crash when saving a file after a sample loop was added
81    
82    * src/gig.cpp, src/gig.h:    * src/gig.cpp, src/gig.h:
83      - fixed segmentation fault in the gig::File destructor sequence which      - fixed segmentation fault in the gig::File destructor sequence which

85      - fixed write support for big-endian systems      - fixed write support for big-endian systems

89          instrument constructors
90        - clear unused fields when saving samples and regions
91        - fixed write support bugs: v3 dimension limits and chunksize

93          couldn't be saved, group name list chunk was placed wrong,
94          dimension region chunks also placed wrong
95        - added initialization of some fixed info strings in file and
96          instrument
97        - write support: files created by libgig will now have the RIFF

100          definition are now saved
101        - added constants for gig file versions
102        - write support: the 3crc and einf chunks are now created or
103          updated when a file is saved (3crc contains sample checksums,
104          einf contains file statistics)
105        - write support: DLSID is now generated on the file and the
106          instruments
107        - write support: improved the default values for dimension region
108          parameters
109        - more write support fixes: crossfade parameters were not saved,
110          v3 dimension limits were not correctly initialized and saved
111          when dimensions were added or deleted, v3 wave pool offsets were
112          not saved correctly
113        - write support: 24 bit samples can now be written
114        - write support: version 3 is now the default for new files
115        - more write support fixes: the 3ewg chunk is now bigger for v3,
116          dimension regions without mapped samples are now allowed, 3gnl
117          list in v3 files now always has 128 entries, several parameters
118          where incorrectly saved due to an operator precedence mistake
119        - DeleteSample now removes all references to the deleted sample
120        - AddDimension now copies all parameters from existing dimension
121          regions and also makes sure that the samplechannel dimension is
122          placed first in the list of dimensions.
123        - added method GetParent() to class 'DimensionRegion', which returns its
124          parent Region
125        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
126          unused areas
127        - added various setter methods to DimensionRegion class which take care
128          of updating lookup tables / caches.
129    
130      * src/RIFF.cpp, src/RIFF.h:
131        - added File::SetByteOrder method
132        - Windows fix: saving a new file didn't work
133    
134      * src/gigdump.cpp:
135        - added some missing dimension strings
