Sat May 31 20:54:39 2014 UTC (6 years, 1 month ago) by schoenebeck
File size: 23288 byte(s)
* gig.h/.cpp: GIG FORMAT EXTENSION: added support for real-time
  instrument scripts.
* RIFF.h/.cpp: added 2nd alternative method for List::MoveSubChunk(),
  the old 1st one allows to move a subchunk within the current List
  whereas the new 2nd one allows to move the subchunk from the
  current list to another list.
* Bumped version (3.3.0.svn13).

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
16 * SoundFont file format:
17 - initial implementation

25
26 * AKAI file format:
27 - Added Linux/POSIX ported version of libakai. Note that libakai is released
28 under LGPL terms while libgig is released under GPL terms. To handle this
29 license difference appropriately the AKAI support part is built as
30 separate DLL (.so file).

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

85
86 * src/gigextract.cpp:
87 - export sample loop, unity note and fine tune with libsndfile
88
89 * src/riftree.cpp:

117 - bugfix: undefined behavior (e.g. endless loop) when opening zero
118 length files, now throws a RIFF::Exception instead (fixes bug #121)
119 - bugfix: destructor for base class RIFF::Chunk accessed members
120 of derived class RIFF::File, which is bad, and caused crashes
121 when using Visual C++
122 - bugfix: files that contain zero length RIFF lists were not read
123 correctly (fixes #127) (bug was introduced 2009-03-13)

164 - added missing parameter initalizations in sample, region and
165 instrument constructors
166 - clear unused fields when saving samples and regions
167 - fixed write support bugs: v3 dimension limits and chunksize

187 when dimensions were added or deleted, v3 wave pool offsets were
188 not saved correctly
189 - write support: 24 bit samples can now be written

193 list in v3 files now always has 128 entries, several parameters
194 where incorrectly saved due to an operator precedence mistake
195 - DeleteSample now removes all references to the deleted sample
196 - AddDimension now copies all parameters from existing dimension
197 regions and also makes sure that the samplechannel dimension is
198 placed first in the list of dimensions.

200 parent Region
201 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
202 unused areas

224 - added "smart midi" and "round robin keyboard" dimensions
225 - added new method File::DeleteGroupOnly() which only deletes the given
226 group but moves all its members to another group, the other method,
227 that is File::DeleteGroup() now removes not just the group, but also
228 all the samples that belong to that group
229 - fixed crash which occured on interfering File::DeleteSample() and
230 File::GetNextSample() calls (due to iterator invalidation)

436 RPM and Debian packages)
437
438 * src/gig.cpp, src/gig.h:
439 - fixed / improved accuracy of all three velocity to volume
440 transformation functions a.k.a. 'nonlinear','linear','special'
441 (patch by Andreas Persson)
442 - denormals are filtered from the velocity to volume tables

472
473 Version 0.7.0 (3 May 2004)
474
475 * general changes:
476 - various big endian specific corrections
477 (successfully tested now on PPC)
478 - minor adjustments to avoid compile errors on some systems
479 (using now pow() instead of powl() and --pedantic g++ compiler switch)
480 - libtoolized the library
481 - added man pages for the command line tools
482 (gigextract, gigdump, dlsdump, rifftree)
483
484 * src/gig.cpp, src/gig.h:
485 - fixed bug in decompression algorithm which caused it not to detect
486 the end of a stream
487 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
488 takes the MIDI key velocity value as an argument and returns the
489 appropriate volume factor (0.0 ... 1.0) for the sample to be played
490 back, the velocity curve transformation functions used for this are
491 only an approximation so far
492 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
493 'Sample::LoopSize' which reflected wrong values
494 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
495 measured in sample points instead of byte offset
496 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
497 'Sample::FineTune'
498 - added class attribute 'Sample::LoopSize'
499 - added method GetInstrument(uint index) to class 'File'
500 - added ReadAndLoop() method to class 'Sample' which is an extension to
501 the normal Read() method to honor the sample's looping information
502 while streaming from disk
503 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
504 'eg2_ctrl_t': replaced this huge enumeration by a structure which
505 reflects the MIDI controller number in case of an ordinary control
506 change controller (this saves a huge switch-case block in the
507 application of the library user)
508 - renamed following attributes in class 'DimensionRegion':
509 'AttenuationContol' -> 'AttenuationController',
510 'InvertAttenuationControl' -> 'InvertAttenuationController',
511 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
512 - minor fix in API documentation for method GetVelocityAttenuation() in
513 class 'DimensionRegion'
514
515 * src/RIFF.cpp, src/RIFF.h:
516 - added additional API documentation
517 - minor fix in Chunk::Read() method (only a minor efficiency issue)
518
519 * src/gigdump.cpp:
