# Line 1  Line 1 
1    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
26    
27      * KORG file format:
28        - initial support for sample based instruments in KORG's file format
29          (.KMP and .KSF files)
30    
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).
36        - Fixed Mac OSX support so that the Akai lib files and tools compile without
37          any exotic third party libraries.
38        - Fixed various compilation errors for Windows.
39        - POSIX fix: open() requires third (mode) argument if used with O_CREAT

52          wrong textual group name
53        - added new method File::AddContentOf() for merging .gig files
54        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
55          controller types (only works with LinuxSampler & gigedit, will not

75    
76      * src/RIFF.cpp, src/RIFF.h:
77        - bugfix: avoid calling read() with count 0 when writing a file,
78          as this may hang on some systems
79        - fixed memory leak and memory handling errors when file loading
80          fails
81        - added new method Chunk::ReadString
82        - added new method File::SetFileName() allowing to call File::Save()

188        - write support: DLSID is now generated on the file and the
189          instruments
190        - write support: improved the default values for dimension region

202        - DeleteSample now removes all references to the deleted sample
203        - AddDimension now copies all parameters from existing dimension
204          regions and also makes sure that the samplechannel dimension is

209          unused areas
210        - added various setter methods to DimensionRegion class which take care
211          of updating lookup tables / caches.
212    
213      * src/RIFF.cpp, src/RIFF.h:
214        - added File::SetByteOrder method
215        - Windows fix: saving a new file didn't work

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

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

271        - sample loop parameters are now taken from the DimensionRegion
272          instead of the wave chunk
273        - keyswitching dimension is changed from split type "normal" to
274          "bit"
275        - real support for 24 bit samples - samples are not truncated to

326          resize and write operations in one rush
327    
328      * src/gigdump.cpp:
