# 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
20        - bugfix: GetPan always returned -1, 0 or 1
21    
22      * KORG file format:
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).
31        - Fixed Mac OSX support so that the Akai lib files and tools compile without
32          any exotic third party libraries.
33        - Fixed various compilation errors for Windows.
34    
35      * src/gig.cpp:

37          weren't saved correctly
38        - implemented File::AddDuplicateInstrument()

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

68    
69      * src/RIFF.cpp, src/RIFF.h:
70        - bugfix: avoid calling read() with count 0 when writing a file,
71          as this may hang on some systems
72        - fixed memory leak and memory handling errors when file loading
73          fails
74        - added new method Chunk::ReadString
75        - added new method File::SetFileName() allowing to call File::Save()
76          later on without passing a file name
77        - added new method File::IsNew()
78        - added support for loading RIFF-like files with a bit different layout

81        - added new method Chunk::GetLayout()
82        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one

103        - bugfix: removed another iterator invalidation in DeleteSample
104        - bugfix in Sample::LoadSampleData*(): reset sample read position to
105          sample start before trying to (re)load sample data from file (#82)
106        - bugfix: EG3 depth parameter was not saved correctly
107        - fixed crash which occured when streaming a gig sample with

109    
110      * src/RIFF.cpp, src/RIFF.h:
111        - bugfix: saving to the same file after the file size had been
112          increased made the file corrupt (#82)
113        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
114          is not written physically yet (#82)

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

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

165          instrument constructors
166        - clear unused fields when saving samples and regions

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

188          not saved correctly
189        - write support: 24 bit samples can now be written
190        - write support: version 3 is now the default for new files
191        - more write support fixes: the 3ewg chunk is now bigger for v3,
192          dimension regions without mapped samples are now allowed, 3gnl
193          list in v3 files now always has 128 entries, several parameters
194          where incorrectly saved due to an operator precedence mistake
195        - DeleteSample now removes all references to the deleted sample
196        - AddDimension now copies all parameters from existing dimension
197          regions and also makes sure that the samplechannel dimension is
198          placed first in the list of dimensions.
199        - added method GetParent() to class 'DimensionRegion', which returns its
200          parent Region
201        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
202          unused areas
203        - added various setter methods to DimensionRegion class which take care
204          of updating lookup tables / caches.
205    
206      * src/RIFF.cpp, src/RIFF.h:
207        - added File::SetByteOrder method
208        - Windows fix: saving a new file didn't work

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

236          when used from Instrument::AddRegion
237        - when saving, override the gig::Regions sample reference simply by
238          the region's first dimension region's sample (avoids an exception

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

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

319          resize and write operations in one rush
320    
321      * src/gigdump.cpp:
