# Line 0  Line 1 
1    Version CVS HEAD (?)
2      * SoundFont file format
3        - initial implementation
4        - changed region lookup API to avoid malloc in RT threads
5    
6      * src/RIFF.cpp, src/RIFF.h:
7        - bugfix: avoid calling read() with count 0 when writing a file,
8          as this may hang on some systems
9    
10    Version 3.3.0 (30 Jul 2009)
11    
12      * general changes:
13        - fixed compilation with gcc 4.3
14        - fixes for building with Visual C++
15        - minor fix in configure for building DLL on Windows
16    
17      * src/gig.cpp, src/gig.h:
18        - added partial support for MIDI rules, only the Controller
19          Triggered rule is supported so far
20        - bugfix: removed another iterator invalidation in DeleteSample
21        - bugfix in Sample::LoadSampleData*(): reset sample read position to
22          sample start before trying to (re)load sample data from file (#82)
23        - bugfix: EG3 depth parameter was not saved correctly
24        - fixed crash which occured when streaming a gig sample with
25          bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
26    
27      * src/RIFF.cpp, src/RIFF.h:
28        - bugfix: saving to the same file after the file size had been
29          increased made the file corrupt (#82)
30        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
31          is not written physically yet (#82)
32        - bugfix: saving to the same file after the file size had been
33          decreased sometimes also made the file corrupt!
34        - bugfix: undefined behavior (e.g. endless loop) when opening zero
35          length files, now throws a RIFF::Exception instead (fixes bug #121)
36        - bugfix: destructor for base class RIFF::Chunk accessed members
37          of derived class RIFF::File, which is bad, and caused crashes
38          when using Visual C++
39        - bugfix: files that contain zero length RIFF lists were not read
40          correctly (fixes #127) (bug was introduced 2009-03-13)
41    
42    Version 3.2.1 (5 Dec 2007)
43    
44      * src/RIFF.cpp, src/RIFF.h:
45        - avoid Windows to perform unnecessary file stream caching which would
46          decrease disk streaming performance on Windows systems otherwise
47    
48      * src/gig.cpp, src/gig.h:
49        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
50          applications to retrieve very superficial informations like amount of
51          instruments and their names in a very fast way
52    
53    Version 3.2.0 (14 Oct 2007)

67        - added Resource::GenerateDLSID function
68        - write support fix: allow regions without mapped samples
69        - added method SetKeyRange() to the Region class which should be used

71        - MoveRegion() method of Region class is now private
72        - added SetGain() method to Sampler class
73        - fixed crash when saving a file after a sample loop was added
74

77          happened when gig::Group informations were accessed before
78        - fixed write support for big-endian systems
79        - defined lengths of a fixed set of info strings. These strings
80          are saved when the file is written, even if they are empty.
81        - added missing parameter initalizations in sample, region and
82          instrument constructors
83        - clear unused fields when saving samples and regions
84        - fixed write support bugs: v3 dimension limits and chunksize

87          dimension region chunks also placed wrong
88        - added initialization of some fixed info strings in file and
89          instrument

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

140          velocity (gig v3 feature)
141        - added "smart midi" and "round robin keyboard" dimensions
142        - added new method File::DeleteGroupOnly() which only deletes the given
143          group but moves all its members to another group, the other method,
144          that is File::DeleteGroup() now removes not just the group, but also
145          all the samples that belong to that group
146        - fixed crash which occured on interfering File::DeleteSample() and
147          File::GetNextSample() calls (due to iterator invalidation)

153          when used from Instrument::AddRegion
154        - when saving, override the gig::Regions sample reference simply by
155          the region's first dimension region's sample (avoids an exception
156          when trying to save a new instrument)
157        - fixed AddDimension() method which did not fill out all mandatory
158          dimension definition fields
159

164    
165      * src/RIFF.cpp, src/RIFF.h:
166        - fixed RIFF::Chunk destructor which did not unregister previously
167          resized chunks, leading to a "zero size chunk" exception when
168          File::Save() was called
169        - added List::MoveSubChunk method

181        - sample loop parameters are now taken from the DimensionRegion
182          instead of the wave chunk
183        - keyswitching dimension is changed from split type "normal" to
184          "bit"
185        - real support for 24 bit samples - samples are not truncated to
186          16 bits anymore
187        - support for reading of ".art" files. (Merging of .art and .gig

218    
219      * src/gig.cpp, src/gig.h:

234          after a Chunk::Resize() and before the File::Save() call to allow
235          placing the new data in the chunk's write buffer and perform the
236          resize and write operations in one rush
237    
238      * src/gigdump.cpp:
239        - fixed to show the correct amount of dimension regions instead of 32

294          (patch by Andreas Persson)
295        - added some file format compatibility checks
296        - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
297          never used, because the necessary check was made before
298          initialization)
299        - fixed crossfade points order (structure for big endian and little

344    
345    Version 1.0.0 (26 Nov 2004)
346    
347      * packaging changes:
348        - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
349          'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
350        - fixed man pages automake install rule (which didn't work on Mandrake,
351          SuSE and Fedora)
352        - fixed generation of Doxygen API documentation (now also included in

367    
368      * src/gigextract.cpp:
369        - added support for libsndfile (if libaudiofile and libsndfile are
370          available then libsndfile is preferred)

380    Version 0.7.1 (2 Jul 2004)
381    
382      * packaging changes:
383        - added libgig.spec and libgig.pc package configurations for generating
384          Redhat packages
385        - header files included on installation.
386        - autotools-generated files removed from CVS repository.
387        - added support for generating Debian packages
388        - version of shared library can be set in configure.in
389    
390    Version 0.7.0 (3 May 2004)
391    
392      * general changes:
393        - various big endian specific corrections
394          (successfully tested now on PPC)
395        - minor adjustments to avoid compile errors on some systems
396          (using now pow() instead of powl() and --pedantic g++ compiler switch)
397        - libtoolized the library
398        - added man pages for the command line tools
399          (gigextract, gigdump, dlsdump, rifftree)
400    
401      * src/gig.cpp, src/gig.h:
402        - fixed bug in decompression algorithm which caused it not to detect
403          the end of a stream
404        - added method GetVelocityAttenuation() to class 'DimensionRegion' which
405          takes the MIDI key velocity value as an argument and returns the
406          appropriate volume factor (0.0 ... 1.0) for the sample to be played
407          back, the velocity curve transformation functions used for this are
408          only an approximation so far
409        - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
410          'Sample::LoopSize' which reflected wrong values
411        - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
412          measured in sample points instead of byte offset
413        - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
414          'Sample::FineTune'
415        - added class attribute 'Sample::LoopSize'
416        - added method GetInstrument(uint index) to class 'File'
417        - added ReadAndLoop() method to class 'Sample' which is an extension to
418          the normal Read() method to honor the sample's looping information
419          while streaming from disk
420        - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
421          'eg2_ctrl_t': replaced this huge enumeration by a structure which
422          reflects the MIDI controller number in case of an ordinary control
423          change controller (this saves a huge switch-case block in the
