# Line 1  Line 1 
1  Version CVS HEAD (?)  Version CVS HEAD (?)
2      * general changes:
3        - minor Makefile fix for parallel make
4        - Mac OS X: link with CoreFoundation (for the UUID function)
5        - removed gcc 4.7 warnings
6        - modernized configure script
7        - removed usage of deprecated Automake variable INCLUDES
8        - added new command line tool "gigmerge"
9        - added "const" keyword to several methods
10        - added new command line tool "gig2mono"
11        - added man page for "sf2dump"
12        - added new command line tool "korgdump" (and a man page for it)
13        - added new command line tool "korg2gig" (and a man page for it)
14        - moved source files of command line tools to new subdir src/tools
15    
16      * SoundFont file format:
17        - initial implementation
18        - changed region lookup API to avoid malloc in RT threads
19        - fixed GetEG1Sustain which didn't return correct value

23        - initial support for sample based instruments in KORG's file format
24          (.KMP and .KSF files)
25    
26      * AKAI file format:
27        - Added Linux/POSIX ported version of libakai. Note that libakai is released
28          under LGPL terms while libgig is released under GPL terms. To handle this
29          license difference appropriately the AKAI support part is built as
30          separate DLL (.so file).

46        - added new method File::AddContentOf() for merging .gig files
47        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
48          controller types (only works with LinuxSampler & gigedit, will not

72          fails
73        - added new method Chunk::ReadString

75          later on without passing a file name
76        - added new method File::IsNew()
77        - added support for loading RIFF-like files with a bit different layout
78          than "real" RIFF files (used for KORG format support)

104          bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
105    
106      * src/RIFF.cpp, src/RIFF.h:
107        - bugfix: saving to the same file after the file size had been
108          increased made the file corrupt (#82)
109        - bugfix: refuse Chunk::Read() in case chunk has just been added, that

114          length files, now throws a RIFF::Exception instead (fixes bug #121)
115        - bugfix: destructor for base class RIFF::Chunk accessed members
116          of derived class RIFF::File, which is bad, and caused crashes
117          when using Visual C++
118        - bugfix: files that contain zero length RIFF lists were not read
119          correctly (fixes #127) (bug was introduced 2009-03-13)
120    
121    Version 3.2.1 (5 Dec 2007)
122    
123      * src/RIFF.cpp, src/RIFF.h:
124        - avoid Windows to perform unnecessary file stream caching which would
125          decrease disk streaming performance on Windows systems otherwise
126    
127      * src/gig.cpp, src/gig.h:
128        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
129          applications to retrieve very superficial informations like amount of
130          instruments and their names in a very fast way
131

148        - added method SetKeyRange() to the Region class which should be used

156          happened when gig::Group informations were accessed before
157        - fixed write support for big-endian systems

161          instrument constructors
162        - clear unused fields when saving samples and regions

173        - added constants for gig file versions
174        - write support: the 3crc and einf chunks are now created or
175          updated when a file is saved (3crc contains sample checksums,
176          einf contains file statistics)
177        - write support: DLSID is now generated on the file and the
178          instruments
179        - write support: improved the default values for dimension region
180          parameters

184          not saved correctly
185        - write support: 24 bit samples can now be written
186        - write support: version 3 is now the default for new files
187        - more write support fixes: the 3ewg chunk is now bigger for v3,
188          dimension regions without mapped samples are now allowed, 3gnl
189          list in v3 files now always has 128 entries, several parameters
190          where incorrectly saved due to an operator precedence mistake
191        - DeleteSample now removes all references to the deleted sample
192        - AddDimension now copies all parameters from existing dimension
193          regions and also makes sure that the samplechannel dimension is

195        - added method GetParent() to class 'DimensionRegion', which returns its
196          parent Region
197        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
198          unused areas
199        - added various setter methods to DimensionRegion class which take care
200          of updating lookup tables / caches.
201    
202      * src/RIFF.cpp, src/RIFF.h:
203        - added File::SetByteOrder method
204        - Windows fix: saving a new file didn't work

219          velocity (gig v3 feature)
220        - added "smart midi" and "round robin keyboard" dimensions
221        - added new method File::DeleteGroupOnly() which only deletes the given
222          group but moves all its members to another group, the other method,
223          that is File::DeleteGroup() now removes not just the group, but also
224          all the samples that belong to that group
225        - fixed crash which occured on interfering File::DeleteSample() and
226          File::GetNextSample() calls (due to iterator invalidation)

232          when used from Instrument::AddRegion
233        - when saving, override the gig::Regions sample reference simply by
234          the region's first dimension region's sample (avoids an exception
235          when trying to save a new instrument)

244      * src/RIFF.cpp, src/RIFF.h:
245        - fixed RIFF::Chunk destructor which did not unregister previously
246          resized chunks, leading to a "zero size chunk" exception when
247          File::Save() was called
248        - added List::MoveSubChunk method

260        - sample loop parameters are now taken from the DimensionRegion
261          instead of the wave chunk
262        - keyswitching dimension is changed from split type "normal" to
263          "bit"
264        - real support for 24 bit samples - samples are not truncated to

310      * src/RIFF.cpp, src/RIFF.h:
311        - added write support
312        - Chunk::LoadChunkData() can now be called again to resize the buffer
313          after a Chunk::Resize() and before the File::Save() call to allow

315          resize and write operations in one rush
316    
317      * src/gigdump.cpp:
318        - fixed to show the correct amount of dimension regions instead of 32

427      - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name      - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
428        'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix        'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
429        - fixed man pages automake install rule (which didn't work on Mandrake,
430          SuSE and Fedora)
431        - fixed generation of Doxygen API documentation (now also included in
432          RPM and Debian packages)
433    
434      * src/gig.cpp, src/gig.h:
435        - fixed / improved accuracy of all three velocity to volume
436          transformation functions a.k.a. 'nonlinear','linear','special'
437          (patch by Andreas Persson)
438        - denormals are filtered from the velocity to volume tables
439        - bugfix for dimension region switching (wrong handling of the release
440          trigger dimension, no bit range check for dimensions of split type
441          'split_type_bit')
442        - fixed panorama value in DimensionRegion (invalid conversion from
443          signed 7 bit to signed 8 bit)
444        - added class attribute 'Layers' to class 'gig::Region'
445        - symbol prototyping of gig::Region (fixes build failure with qsampler)
446    
447      * src/gigextract.cpp:
448        - added support for libsndfile (if libaudiofile and libsndfile are
449          available then libsndfile is preferred)
450    
451      * src/gigdump.cpp:
452        - added printout for dimension informations (amount, type, bits, zones)
453        - added printout for velocity response curve parameters
454        - added printout for crossfade definitions
455        - added printout for panorama value for each DimensionRegion
456        - replaced printout of DLS Region layer by printout of amount of
457          Gigasampler layers
