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

62          lengths can be specified for each INFO chunk
63        - added Resource::GenerateDLSID function
64        - write support fix: allow regions without mapped samples
65        - added method SetKeyRange() to the Region class which should be used
66          instead of setting the KeyRange member variable directly
67        - MoveRegion() method of Region class is now private
68        - added SetGain() method to Sampler class
69        - fixed crash when saving a file after a sample loop was added
70

73          happened when gig::Group informations were accessed before
74        - fixed write support for big-endian systems
75        - defined lengths of a fixed set of info strings. These strings
76          are saved when the file is written, even if they are empty.
77        - added missing parameter initalizations in sample, region and
78          instrument constructors
79        - clear unused fields when saving samples and regions
80        - fixed write support bugs: v3 dimension limits and chunksize
81          weren't saved, leverage controller of type controlchange
82          couldn't be saved, group name list chunk was placed wrong,
83          dimension region chunks also placed wrong
84        - added initialization of some fixed info strings in file and
85          instrument
86        - write support: files created by libgig will now have the RIFF

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

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

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

160    
161      * src/RIFF.cpp, src/RIFF.h:
162        - fixed RIFF::Chunk destructor which did not unregister previously
163          resized chunks, leading to a "zero size chunk" exception when
164          File::Save() was called
165        - added List::MoveSubChunk method
166

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

214    
215      * src/gig.cpp, src/gig.h:

230          after a Chunk::Resize() and before the File::Save() call to allow
231          placing the new data in the chunk's write buffer and perform the
232          resize and write operations in one rush
233    
234      * src/gigdump.cpp:
235        - fixed to show the correct amount of dimension regions instead of 32

289          articulation informations are ignored at the moment
290          (patch by Andreas Persson)
291        - added some file format compatibility checks
292        - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
293          never used, because the necessary check was made before
294          initialization)
295        - fixed crossfade points order (structure for big endian and little

340    
341    Version 1.0.0 (26 Nov 2004)
342    
343      * packaging changes:
344        - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
345          'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
346        - fixed man pages automake install rule (which didn't work on Mandrake,
347          SuSE and Fedora)
348        - fixed generation of Doxygen API documentation (now also included in

361        - added class attribute 'Layers' to class 'gig::Region'
362        - symbol prototyping of gig::Region (fixes build failure with qsampler)
363    
364      * src/gigextract.cpp:
365        - added support for libsndfile (if libaudiofile and libsndfile are
366          available then libsndfile is preferred)

375    
376    Version 0.7.1 (2 Jul 2004)
377    
378      * packaging changes:
379        - added libgig.spec and libgig.pc package configurations for generating
380          Redhat packages
381        - header files included on installation.
382        - autotools-generated files removed from CVS repository.
383        - added support for generating Debian packages
384        - version of shared library can be set in configure.in
385    
386    Version 0.7.0 (3 May 2004)
387    
388      * general changes:
389        - various big endian specific corrections
390          (successfully tested now on PPC)
391        - minor adjustments to avoid compile errors on some systems
392          (using now pow() instead of powl() and --pedantic g++ compiler switch)
393        - libtoolized the library
394        - added man pages for the command line tools
395          (gigextract, gigdump, dlsdump, rifftree)
396    
397      * src/gig.cpp, src/gig.h:
398        - fixed bug in decompression algorithm which caused it not to detect
399          the end of a stream
400        - added method GetVelocityAttenuation() to class 'DimensionRegion' which
401          takes the MIDI key velocity value as an argument and returns the
402          appropriate volume factor (0.0 ... 1.0) for the sample to be played
403          back, the velocity curve transformation functions used for this are
404          only an approximation so far
405        - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
406          'Sample::LoopSize' which reflected wrong values
407        - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
408          measured in sample points instead of byte offset
409        - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
410          'Sample::FineTune'
411        - added class attribute 'Sample::LoopSize'
412        - added method GetInstrument(uint index) to class 'File'
413        - added ReadAndLoop() method to class 'Sample' which is an extension to
414          the normal Read() method to honor the sample's looping information
415          while streaming from disk
416        - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
417          'eg2_ctrl_t': replaced this huge enumeration by a structure which
418          reflects the MIDI controller number in case of an ordinary control
419          change controller (this saves a huge switch-case block in the
420          application of the library user)
421        - renamed following attributes in class 'DimensionRegion':
422          'AttenuationContol' -> 'AttenuationController',
423          'InvertAttenuationControl' -> 'InvertAttenuationController',
