# 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        - added new command line tool "gig2stereo" (and a man page for it)
21    
22      * SoundFont file format:
23        - initial implementation
24        - changed region lookup API to avoid malloc in RT threads
25        - fixed GetEG1Sustain which didn't return correct value
26        - bugfix: GetPan always returned -1, 0 or 1
27    
28      * KORG file format:
29        - initial support for sample based instruments in KORG's file format
30          (.KMP and .KSF files)
31    
32      * AKAI file format:
33        - Added Linux/POSIX ported version of libakai. Note that libakai is released
34          under LGPL terms while libgig is released under GPL terms. To handle this
35          license difference appropriately the AKAI support part is built as
36          separate DLL (.so file).
37        - Fixed Mac OSX support so that the Akai lib files and tools compile without
38          any exotic third party libraries.
39        - Fixed various compilation errors for Windows.
40        - POSIX fix: open() requires third (mode) argument if used with O_CREAT
41          (fixes #219).
42    
43      * src/gig.cpp:
44        - bugfix: VCF velocity dynamic range and VCF velocity curve

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

73          new one being dropped after save operation and the gig file being tainted
74          (chunks at wrong location in the RIFF tree).
75        - Added new method Instrument::MoveTo() which allows to rearrange the order
76          of instruments within the same gig file.
77    
78      * src/DLS.cpp, src/DLS.h:
79        - added new method File::GetFileName()
80        - fixed minor "memory leak on exception" bug found with cppcheck
81        - added new method File::GetExtensionFile(int index)
82        - added new method File::SetFileName() allowing to call File::Save()
83          later on without passing a file name
84        - added inline helper methods overlaps() for struct range_t
85        - Added support for custom progress notification while saving to DLS file.
86        - Bugfix: Adding a new region in between two existing regions caused the
87          new one being dropped after save operation and the gig file being tainted
88          (chunks at wrong location in the RIFF tree).
89    
90      * src/RIFF.cpp, src/RIFF.h:
91        - bugfix: avoid calling read() with count 0 when writing a file,

100          than "real" RIFF files (used for KORG format support)
101        - added new method Chunk::GetFile()
102        - added new method Chunk::GetLayout()
103        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
104          allows to move a subchunk within the current List, whereas the new 2nd
105          one allows to move the subchunk from the current list to another list
106        - POSIX: only assume -1 result value as error on open() calls
107        - POSIX: show operating system's error reason if opening a file failed
108        - Added support for custom progress notification while saving to RIFF file.
109        - Fixed embarrassing old bug: POSIX read() errors were never detected on
110          Chunk::Read() calls due to signment incompatible variable.
111        - Cleanup of an old DLL binary backward compatibility hack.
112    
113      * src/gigextract.cpp:

130        - bugfix: removed another iterator invalidation in DeleteSample
131        - bugfix in Sample::LoadSampleData*(): reset sample read position to
132          sample start before trying to (re)load sample data from file (#82)
133        - bugfix: EG3 depth parameter was not saved correctly
134        - fixed crash which occured when streaming a gig sample with
135          bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
136    
137      * src/RIFF.cpp, src/RIFF.h:
138        - bugfix: saving to the same file after the file size had been
139          increased made the file corrupt (#82)
140        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
141          is not written physically yet (#82)
142        - bugfix: saving to the same file after the file size had been
143          decreased sometimes also made the file corrupt!
144        - bugfix: undefined behavior (e.g. endless loop) when opening zero
145          length files, now throws a RIFF::Exception instead (fixes bug #121)
146        - bugfix: destructor for base class RIFF::Chunk accessed members
147          of derived class RIFF::File, which is bad, and caused crashes
148          when using Visual C++

150          correctly (fixes #127) (bug was introduced 2009-03-13)
151    
152    Version 3.2.1 (5 Dec 2007)
153    
154      * src/RIFF.cpp, src/RIFF.h:

156          decrease disk streaming performance on Windows systems otherwise
157    
158      * src/gig.cpp, src/gig.h:
159        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing

207          einf contains file statistics)
208        - write support: DLSID is now generated on the file and the
209          instruments
210        - write support: improved the default values for dimension region
211          parameters

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

231          of updating lookup tables / caches.
232    
233      * src/RIFF.cpp, src/RIFF.h:
234        - added File::SetByteOrder method

250          velocity (gig v3 feature)
251        - added "smart midi" and "round robin keyboard" dimensions
252        - added new method File::DeleteGroupOnly() which only deletes the given
253          group but moves all its members to another group, the other method,
254          that is File::DeleteGroup() now removes not just the group, but also
255          all the samples that belong to that group
256        - fixed crash which occured on interfering File::DeleteSample() and

292          instead of the wave chunk
293        - keyswitching dimension is changed from split type "normal" to
294          "bit"
295        - real support for 24 bit samples - samples are not truncated to
