# 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        - libgig.so and libakai.so files are now installed under
16          $(prefix)/lib/libgig/ by default.
17        - Header files are now installed under $(prefix)/include/libgig/ by default.
18        - Fixed various packaging issues regarding installation directories
19          (fixes #218).
20    
21      * SoundFont file format:
22        - initial implementation
23        - changed region lookup API to avoid malloc in RT threads
24        - fixed GetEG1Sustain which didn't return correct value
25        - bugfix: GetPan always returned -1, 0 or 1

31      * AKAI file format:
32        - Added Linux/POSIX ported version of libakai. Note that libakai is released
33          under LGPL terms while libgig is released under GPL terms. To handle this
34          license difference appropriately the AKAI support part is built as
35          separate DLL (.so file).

75        - bugfix: avoid calling read() with count 0 when writing a file,
76          as this may hang on some systems
77        - fixed memory leak and memory handling errors when file loading
78          fails
79        - added new method Chunk::ReadString
80        - added new method File::SetFileName() allowing to call File::Save()
81          later on without passing a file name
82        - added new method File::IsNew()
83        - added support for loading RIFF-like files with a bit different layout

114    
115      * src/RIFF.cpp, src/RIFF.h:
116        - bugfix: saving to the same file after the file size had been
117          increased made the file corrupt (#82)
118        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
119          is not written physically yet (#82)

123          length files, now throws a RIFF::Exception instead (fixes bug #121)
124        - bugfix: destructor for base class RIFF::Chunk accessed members
125          of derived class RIFF::File, which is bad, and caused crashes
126          when using Visual C++
127        - bugfix: files that contain zero length RIFF lists were not read
128          correctly (fixes #127) (bug was introduced 2009-03-13)
129    
130    Version 3.2.1 (5 Dec 2007)
131    
132      * src/RIFF.cpp, src/RIFF.h:
133        - avoid Windows to perform unnecessary file stream caching which would
134          decrease disk streaming performance on Windows systems otherwise
135    
136      * src/gig.cpp, src/gig.h:
137        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
138          applications to retrieve very superficial informations like amount of
139          instruments and their names in a very fast way
140

156        - write support fix: allow regions without mapped samples
157        - added method SetKeyRange() to the Region class which should be used

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

170          instrument constructors
171        - clear unused fields when saving samples and regions

182        - added constants for gig file versions
183        - write support: the 3crc and einf chunks are now created or
184          updated when a file is saved (3crc contains sample checksums,
185          einf contains file statistics)
186        - write support: DLSID is now generated on the file and the
187          instruments
188        - write support: improved the default values for dimension region
189          parameters

193          not saved correctly
194        - write support: 24 bit samples can now be written
195        - write support: version 3 is now the default for new files
196        - more write support fixes: the 3ewg chunk is now bigger for v3,
197          dimension regions without mapped samples are now allowed, 3gnl

199          where incorrectly saved due to an operator precedence mistake
200        - DeleteSample now removes all references to the deleted sample
201        - AddDimension now copies all parameters from existing dimension
202          regions and also makes sure that the samplechannel dimension is

204        - added method GetParent() to class 'DimensionRegion', which returns its
205          parent Region
206        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
207          unused areas
208        - added various setter methods to DimensionRegion class which take care
209          of updating lookup tables / caches.
210    
211      * src/RIFF.cpp, src/RIFF.h:
212        - added File::SetByteOrder method
213        - Windows fix: saving a new file didn't work

226        - custom velocity splits now works for gig v3 files too
227        - added support for custom splits points for other dimensions than
228          velocity (gig v3 feature)
229        - added "smart midi" and "round robin keyboard" dimensions
230        - added new method File::DeleteGroupOnly() which only deletes the given
231          group but moves all its members to another group, the other method,
232          that is File::DeleteGroup() now removes not just the group, but also
233          all the samples that belong to that group
234        - fixed crash which occured on interfering File::DeleteSample() and
235          File::GetNextSample() calls (due to iterator invalidation)

240        - fixed constructor for Region, which did not initialize correctly
241          when used from Instrument::AddRegion
242        - when saving, override the gig::Regions sample reference simply by
243          the region's first dimension region's sample (avoids an exception
244          when trying to save a new instrument)
245        - fixed AddDimension() method which did not fill out all mandatory
246          dimension definition fields
247

252    
253      * src/RIFF.cpp, src/RIFF.h:
254        - fixed RIFF::Chunk destructor which did not unregister previously
255          resized chunks, leading to a "zero size chunk" exception when
256          File::Save() was called
257        - added List::MoveSubChunk method
258

267          inside a region (for example different velocity split levels for
268          pedal up and pedal down)
269        - sample loop parameters are now taken from the DimensionRegion
270          instead of the wave chunk
271        - keyswitching dimension is changed from split type "normal" to
272          "bit"
273        - real support for 24 bit samples - samples are not truncated to
274          16 bits anymore
275        - support for reading of ".art" files. (Merging of .art and .gig
276          files are not implemented yet.)

305          crash when a multi-file gig was deallocated
306    
307      * src/gig.cpp, src/gig.h:

320        - added write support
321        - Chunk::LoadChunkData() can now be called again to resize the buffer
322          after a Chunk::Resize() and before the File::Save() call to allow
323          placing the new data in the chunk's write buffer and perform the
324          resize and write operations in one rush
325    
326      * src/gigdump.cpp:
327        - fixed to show the correct amount of dimension regions instead of 32

382          (patch by Andreas Persson)
383        - added some file format compatibility checks
384        - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
385          never used, because the necessary check was made before
