# 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
40          (fixes #219).

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

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

138          decrease disk streaming performance on Windows systems otherwise
139    
140      * src/gig.cpp, src/gig.h:
141        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing

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

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

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

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

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

328          resize and write operations in one rush
329    
330      * src/gigdump.cpp:
