* bugfix: saving to the same file after the file size had been
  decreased sometimes made the file corrupt

1 persson 1627 Version CVS HEAD (?)
2    
3 persson 1713 * general changes:
4     - fixed compilation with gcc 4.3
5    
6 persson 1627 * src/gig.cpp, src/gig.h:

8     Triggered rule is supported so far
9 persson 1678 - bugfix: removed another iterator invalidation in DeleteSample
10 schoenebeck 1851 - bugfix in Sample::LoadSampleData*(): reset sample read position to
11     sample start before trying to (re)load sample data from file (#82)
12 persson 1627
13 persson 1678 * src/RIFF.cpp, src/RIFF.h:

78     instruments
79 persson 1218 - write support: improved the default values for dimension region
80     parameters
81 persson 1247 - more write support fixes: crossfade parameters were not saved,

88     dimension regions without mapped samples are now allowed, 3gnl
89     list in v3 files now always has 128 entries, several parameters
90     where incorrectly saved due to an operator precedence mistake
91     - DeleteSample now removes all references to the deleted sample
92 persson 1301 - AddDimension now copies all parameters from existing dimension
93     regions and also makes sure that the samplechannel dimension is

275 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

359 capela 168 Version 0.7.1 (2 Jul 2004)
360    
361     * packaging changes:
362 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
363     Redhat packages
364 capela 168 - header files included on installation.
365     - autotools-generated files removed from CVS repository.
366 schoenebeck 186 - added support for generating Debian packages
367     - version of shared library can be set in configure.in
368    
369 schoenebeck 58 Version 0.7.0 (3 May 2004)
370    
371     * general changes:
372     - various big endian specific corrections
373     (successfully tested now on PPC)
374     - minor adjustments to avoid compile errors on some systems
375     (using now pow() instead of powl() and --pedantic g++ compiler switch)
376     - libtoolized the library
377     - added man pages for the command line tools
378     (gigextract, gigdump, dlsdump, rifftree)
379    
380     * src/gig.cpp, src/gig.h:
381     - fixed bug in decompression algorithm which caused it not to detect
382     the end of a stream
383     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
384     takes the MIDI key velocity value as an argument and returns the
385     appropriate volume factor (0.0 ... 1.0) for the sample to be played
386     back, the velocity curve transformation functions used for this are
387     only an approximation so far
388     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
389     'Sample::LoopSize' which reflected wrong values
390     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
391     measured in sample points instead of byte offset
392     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
393     'Sample::FineTune'
394     - added class attribute 'Sample::LoopSize'
395     - added method GetInstrument(uint index) to class 'File'
396     - added ReadAndLoop() method to class 'Sample' which is an extension to
397     the normal Read() method to honor the sample's looping information
398     while streaming from disk
399     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
400     'eg2_ctrl_t': replaced this huge enumeration by a structure which
401     reflects the MIDI controller number in case of an ordinary control
402     change controller (this saves a huge switch-case block in the
403     application of the library user)
404     - renamed following attributes in class 'DimensionRegion':
405     'AttenuationContol' -> 'AttenuationController',
406     'InvertAttenuationControl' -> 'InvertAttenuationController',
407     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
408     - minor fix in API documentation for method GetVelocityAttenuation() in
409     class 'DimensionRegion'
410    
411     * src/RIFF.cpp, src/RIFF.h:
412     - added additional API documentation
413     - minor fix in Chunk::Read() method (only a minor efficiency issue)
414    
415     * src/gigdump.cpp:
