# 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        - added new command line tool "gig2stereo" (and a man page for it)
21        - unit tests: fixed wrong return value when test suite app exits
22          (patch by Ryan Schmidt)
23        - added new command line tool "sf2extract" (and a man page for it)
24    
25      * SoundFont file format:
26        - initial implementation
27        - changed region lookup API to avoid malloc in RT threads
28        - fixed GetEG1Sustain which didn't return correct value
29        - bugfix: GetPan always returned -1, 0 or 1
30    
31      * KORG file format:
32        - initial support for sample based instruments in KORG's file format
33          (.KMP and .KSF files)
34    
35      * AKAI file format:
36        - Added Linux/POSIX ported version of libakai. Note that libakai is released
37          under LGPL terms while libgig is released under GPL terms. To handle this
38          license difference appropriately the AKAI support part is built as
39          separate DLL (.so file).
40        - Fixed Mac OSX support so that the Akai lib files and tools compile without
41          any exotic third party libraries.
42        - Fixed various compilation errors for Windows.
43        - POSIX fix: open() requires third (mode) argument if used with O_CREAT
44          (fixes #219).
45    
46      * src/gig.cpp:
47        - bugfix: VCF velocity dynamic range and VCF velocity curve
48          weren't saved correctly

56          wrong textual group name
57        - added new method File::AddContentOf() for merging .gig files
58        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
59          controller types (only works with LinuxSampler & gigedit, will not
60          work with Gigasampler/GigaStudio)

71        - added new method Region::GetDimensionRegionIndexByValue()
72        - added new method Script::GetGroup()
73        - added new method Region::SetDimensionType()

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

103          later on without passing a file name
104        - added new method File::IsNew()
105        - added support for loading RIFF-like files with a bit different layout
106          than "real" RIFF files (used for KORG format support)
107        - added new method Chunk::GetFile()
108        - added new method Chunk::GetLayout()
109        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
110          allows to move a subchunk within the current List, whereas the new 2nd
111          one allows to move the subchunk from the current list to another list
112        - POSIX: only assume -1 result value as error on open() calls
113        - POSIX: show operating system's error reason if opening a file failed
114        - Added support for custom progress notification while saving to RIFF file.
115        - Fixed embarrassing old bug: POSIX read() errors were never detected on
116          Chunk::Read() calls due to signment incompatible variable.
117        - Cleanup of an old DLL binary backward compatibility hack.
118    
119      * src/gigextract.cpp:

136        - bugfix: removed another iterator invalidation in DeleteSample
137        - bugfix in Sample::LoadSampleData*(): reset sample read position to
138          sample start before trying to (re)load sample data from file (#82)

142    
143      * src/RIFF.cpp, src/RIFF.h:
144        - bugfix: saving to the same file after the file size had been
145          increased made the file corrupt (#82)
146        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
147          is not written physically yet (#82)
148        - bugfix: saving to the same file after the file size had been
149          decreased sometimes also made the file corrupt!
150        - bugfix: undefined behavior (e.g. endless loop) when opening zero
151          length files, now throws a RIFF::Exception instead (fixes bug #121)
152        - bugfix: destructor for base class RIFF::Chunk accessed members
153          of derived class RIFF::File, which is bad, and caused crashes
154          when using Visual C++
155        - bugfix: files that contain zero length RIFF lists were not read
156          correctly (fixes #127) (bug was introduced 2009-03-13)
157    
158    Version 3.2.1 (5 Dec 2007)
159    
160      * src/RIFF.cpp, src/RIFF.h:
161        - avoid Windows to perform unnecessary file stream caching which would
162          decrease disk streaming performance on Windows systems otherwise

213          einf contains file statistics)
214        - write support: DLSID is now generated on the file and the
215          instruments
216        - write support: improved the default values for dimension region
217          parameters

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

232        - added method GetParent() to class 'DimensionRegion', which returns its
233          parent Region
234        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
235          unused areas
236        - added various setter methods to DimensionRegion class which take care
237          of updating lookup tables / caches.
238    
239      * src/RIFF.cpp, src/RIFF.h:
240        - added File::SetByteOrder method
241        - Windows fix: saving a new file didn't work

254        - custom velocity splits now works for gig v3 files too
255        - added support for custom splits points for other dimensions than
256          velocity (gig v3 feature)
257        - added "smart midi" and "round robin keyboard" dimensions
258        - added new method File::DeleteGroupOnly() which only deletes the given
259          group but moves all its members to another group, the other method,
260          that is File::DeleteGroup() now removes not just the group, but also
261          all the samples that belong to that group
262        - fixed crash which occured on interfering File::DeleteSample() and
263          File::GetNextSample() calls (due to iterator invalidation)

269          when used from Instrument::AddRegion
270        - when saving, override the gig::Regions sample reference simply by
271          the region's first dimension region's sample (avoids an exception
272          when trying to save a new instrument)
273        - fixed AddDimension() method which did not fill out all mandatory
274          dimension definition fields
275

297        - sample loop parameters are now taken from the DimensionRegion
298          instead of the wave chunk
299        - keyswitching dimension is changed from split type "normal" to
300          "bit"
301        - real support for 24 bit samples - samples are not truncated to
302          16 bits anymore
303        - support for reading of ".art" files. (Merging of .art and .gig
304          files are not implemented yet.)

333          crash when a multi-file gig was deallocated
334    
335      * src/gig.cpp, src/gig.h:

352          resize and write operations in one rush
353    
354      * src/gigdump.cpp:
355        - fixed to show the correct amount of dimension regions instead of 32

427        - added v3 "random" and "round robin" dimensions
428        - implemented progress indicator callback mechanism for loading
429          instruments and samples
430        - added functions libraryName() and libraryVersion()
431    
432      * src/DLS.cpp, src/DLS.h:
433        - fixed File constructor which caused variable File::Instruments always
434          to be zero
435        - added functions libraryName() and libraryVersion()
436    
437      * src/RIFF.cpp, src/RIFF.h:
438        - fixed method List::LoadSubChunks() which did not restore the original
439          position within the body of the given list chunk
440        - added functions libraryName() and libraryVersion()
441    
442      * src/rifftree.cpp:
443        - added command line switch -v to show rifftree's revision and the used
444          libgig version

448          libgig version
449    
450      * src/gigdump.cpp:
451        - added output of UnityNote, FineTune, Gain, SampleStartOffset an
452          LoopPlayCount
453        - added command line switch -v to show gigdump's revision and the used
454          libgig version
455    
456      * src/gigextract.cpp:
457        - support for compressed mono samples and compressed 24 bit samples
458        - added command line switch -v to show gigextract's revision and the
459          used libgig version

461    Version 1.0.0 (26 Nov 2004)
462    
463      * packaging changes:
464        - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
465          'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
466        - fixed man pages automake install rule (which didn't work on Mandrake,
467          SuSE and Fedora)
468        - fixed generation of Doxygen API documentation (now also included in
469          RPM and Debian packages)
470    
471      * src/gig.cpp, src/gig.h:
472        - fixed / improved accuracy of all three velocity to volume
473          transformation functions a.k.a. 'nonlinear','linear','special'
474          (patch by Andreas Persson)
475        - denormals are filtered from the velocity to volume tables
476        - bugfix for dimension region switching (wrong handling of the release
477          trigger dimension, no bit range check for dimensions of split type
478          'split_type_bit')
479        - fixed panorama value in DimensionRegion (invalid conversion from
480          signed 7 bit to signed 8 bit)
481        - added class attribute 'Layers' to class 'gig::Region'
482        - symbol prototyping of gig::Region (fixes build failure with qsampler)
483    
484      * src/gigextract.cpp:
485        - added support for libsndfile (if libaudiofile and libsndfile are
486          available then libsndfile is preferred)
487    
488      * src/gigdump.cpp:
489        - added printout for dimension informations (amount, type, bits, zones)
490        - added printout for velocity response curve parameters
491        - added printout for crossfade definitions
492        - added printout for panorama value for each DimensionRegion
493        - replaced printout of DLS Region layer by printout of amount of
494          Gigasampler layers
