Sun Feb 10 16:07:22 2008 UTC (16 years, 1 month ago) by persson
File size: 17725 byte(s)
* bugfix: saving to the same file after the file size had been
  increased made the file corrupt (#82)
* bugfix: removed another iterator invalidation in DeleteSample
* changed the functions for midi rules, to get rid of the iterator

1 persson 1627 Version CVS HEAD (?)
2    
3     * src/gig.cpp, src/gig.h:
4     - added partial support for MIDI rules, only the Controller
5     Triggered rule is supported so far

52     instrument constructors
53     - clear unused fields when saving samples and regions
54     - fixed write support bugs: v3 dimension limits and chunksize

67     einf contains file statistics)
68 persson 1209 - write support: DLSID is now generated on the file and the
69     instruments
70 persson 1218 - write support: improved the default values for dimension region
71     parameters
72 persson 1247 - more write support fixes: crossfade parameters were not saved,

77     - write support: version 3 is now the default for new files
78 persson 1266 - more write support fixes: the 3ewg chunk is now bigger for v3,
79     dimension regions without mapped samples are now allowed, 3gnl
80     list in v3 files now always has 128 entries, several parameters
81     where incorrectly saved due to an operator precedence mistake
82     - DeleteSample now removes all references to the deleted sample
83 persson 1301 - AddDimension now copies all parameters from existing dimension
84     regions and also makes sure that the samplechannel dimension is

266 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

350 capela 168 Version 0.7.1 (2 Jul 2004)
351    
352     * packaging changes:
353 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
354     Redhat packages
355 capela 168 - header files included on installation.
356     - autotools-generated files removed from CVS repository.
357 schoenebeck 186 - added support for generating Debian packages
358     - version of shared library can be set in configure.in
359    
360 schoenebeck 58 Version 0.7.0 (3 May 2004)
361    
362     * general changes:
363     - various big endian specific corrections
364     (successfully tested now on PPC)
365     - minor adjustments to avoid compile errors on some systems
366     (using now pow() instead of powl() and --pedantic g++ compiler switch)
367     - libtoolized the library
368     - added man pages for the command line tools
369     (gigextract, gigdump, dlsdump, rifftree)
370    
371     * src/gig.cpp, src/gig.h:
372     - fixed bug in decompression algorithm which caused it not to detect
373     the end of a stream
374     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
375     takes the MIDI key velocity value as an argument and returns the
376     appropriate volume factor (0.0 ... 1.0) for the sample to be played
377     back, the velocity curve transformation functions used for this are
378     only an approximation so far
379     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
380     'Sample::LoopSize' which reflected wrong values
381     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
382     measured in sample points instead of byte offset
383     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
384     'Sample::FineTune'
385     - added class attribute 'Sample::LoopSize'
386     - added method GetInstrument(uint index) to class 'File'
387     - added ReadAndLoop() method to class 'Sample' which is an extension to
388     the normal Read() method to honor the sample's looping information
389     while streaming from disk
390     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
391     'eg2_ctrl_t': replaced this huge enumeration by a structure which
392     reflects the MIDI controller number in case of an ordinary control
393     change controller (this saves a huge switch-case block in the
394     application of the library user)
395     - renamed following attributes in class 'DimensionRegion':
396     'AttenuationContol' -> 'AttenuationController',
397     'InvertAttenuationControl' -> 'InvertAttenuationController',
398     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
399     - minor fix in API documentation for method GetVelocityAttenuation() in
400     class 'DimensionRegion'
401    
402     * src/RIFF.cpp, src/RIFF.h:
403     - added additional API documentation
404     - minor fix in Chunk::Read() method (only a minor efficiency issue)
405    
406     * src/gigdump.cpp:
407     - added printout of samples' looping informations
408    
409 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
410    
411     * initial release
