# 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
26

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).

37          any exotic third party libraries.

78    
79      * src/RIFF.cpp, src/RIFF.h:
80        - bugfix: avoid calling read() with count 0 when writing a file,
81          as this may hang on some systems

191        - write support: DLSID is now generated on the file and the
192          instruments
193        - write support: improved the default values for dimension region

205        - DeleteSample now removes all references to the deleted sample
206        - AddDimension now copies all parameters from existing dimension

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