14 persson 1627

85     instruments
86 persson 1218 - write support: improved the default values for dimension region
87     parameters
88 persson 1247 - more write support fixes: crossfade parameters were not saved,

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

282 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

333     * packaging changes:
334     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

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