22 persson 1266 - write support fix: allow regions without mapped samples
23 schoenebeck 1335 - added method SetKeyRange() to the Region class which should be used

31     happened when gig::Group informations were accessed before
32 persson 1179 - fixed write support for big-endian systems

36     instrument constructors
37     - clear unused fields when saving samples and regions
38     - fixed write support bugs: v3 dimension limits and chunksize

41     dimension region chunks also placed wrong
42 persson 1182 - added initialization of some fixed info strings in file and
43     instrument

51     einf contains file statistics)
52 persson 1209 - write support: DLSID is now generated on the file and the
53     instruments
54 persson 1218 - write support: improved the default values for dimension region
55     parameters
56 persson 1247 - more write support fixes: crossfade parameters were not saved,
57     v3 dimension limits were not correctly initialized and saved

61     - write support: version 3 is now the default for new files
62 persson 1266 - more write support fixes: the 3ewg chunk is now bigger for v3,
63     dimension regions without mapped samples are now allowed, 3gnl
64     list in v3 files now always has 128 entries, several parameters
65     where incorrectly saved due to an operator precedence mistake
66     - DeleteSample now removes all references to the deleted sample
67 persson 1301 - AddDimension now copies all parameters from existing dimension
68     regions and also makes sure that the samplechannel dimension is
69     placed first in the list of dimensions.

95 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
96 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
97     group but moves all its members to another group, the other method,
98     that is File::DeleteGroup() now removes not just the group, but also
99     all the samples that belong to that group

250 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

314 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
315     trigger dimension, no bit range check for dimensions of split type
316     'split_type_bit')
317 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from

334 capela 168 Version 0.7.1 (2 Jul 2004)
335    
336     * packaging changes:

341 schoenebeck 186 - added support for generating Debian packages
342     - version of shared library can be set in configure.in
343    
344 schoenebeck 58 Version 0.7.0 (3 May 2004)
345    
346     * general changes:
347     - various big endian specific corrections
348     (successfully tested now on PPC)
349     - minor adjustments to avoid compile errors on some systems
350     (using now pow() instead of powl() and --pedantic g++ compiler switch)
351     - libtoolized the library
352     - added man pages for the command line tools
353     (gigextract, gigdump, dlsdump, rifftree)
354    
355     * src/gig.cpp, src/gig.h:
356     - fixed bug in decompression algorithm which caused it not to detect
357     the end of a stream
358     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
359     takes the MIDI key velocity value as an argument and returns the
360     appropriate volume factor (0.0 ... 1.0) for the sample to be played
361     back, the velocity curve transformation functions used for this are
362     only an approximation so far
363     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
364     'Sample::LoopSize' which reflected wrong values
365     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
366     measured in sample points instead of byte offset
367     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
368     'Sample::FineTune'
369     - added class attribute 'Sample::LoopSize'
370     - added method GetInstrument(uint index) to class 'File'
371     - added ReadAndLoop() method to class 'Sample' which is an extension to
372     the normal Read() method to honor the sample's looping information
373     while streaming from disk
374     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
375     'eg2_ctrl_t': replaced this huge enumeration by a structure which
376     reflects the MIDI controller number in case of an ordinary control
377     change controller (this saves a huge switch-case block in the
378     application of the library user)
379     - renamed following attributes in class 'DimensionRegion':
380     'AttenuationContol' -> 'AttenuationController',
381     'InvertAttenuationControl' -> 'InvertAttenuationController',
382     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
383     - minor fix in API documentation for method GetVelocityAttenuation() in
384     class 'DimensionRegion'
385    
386     * src/RIFF.cpp, src/RIFF.h:
387     - added additional API documentation
388     - minor fix in Chunk::Read() method (only a minor efficiency issue)
389    
390     * src/gigdump.cpp:
391     - added printout of samples' looping informations
392    
393 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
394    
395     * initial release
