13     lengths can be specified for each INFO chunk
14 persson 1209 - added Resource::GenerateDLSID function
15 persson 1266 - write support fix: allow regions without mapped samples
16 schoenebeck 1335 - added method SetKeyRange() to the Region class which should be used

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

26     are saved when the file is written, even if they are empty.
27 persson 1182 - added missing parameter initalizations in sample, region and
28     instrument constructors
29     - clear unused fields when saving samples and regions
30     - fixed write support bugs: v3 dimension limits and chunksize

32 persson 1195 couldn't be saved, group name list chunk was placed wrong,
33     dimension region chunks also placed wrong
34 persson 1182 - added initialization of some fixed info strings in file and
35     instrument
36 persson 1192 - write support: files created by libgig will now have the RIFF

43     einf contains file statistics)
44 persson 1209 - write support: DLSID is now generated on the file and the
45     instruments
46 persson 1218 - write support: improved the default values for dimension region
47     parameters
48 persson 1247 - more write support fixes: crossfade parameters were not saved,
49     v3 dimension limits were not correctly initialized and saved
50     when dimensions were added or deleted, v3 wave pool offsets were
51     not saved correctly

53     - write support: version 3 is now the default for new files
54 persson 1266 - more write support fixes: the 3ewg chunk is now bigger for v3,
55     dimension regions without mapped samples are now allowed, 3gnl
56     list in v3 files now always has 128 entries, several parameters
57     where incorrectly saved due to an operator precedence mistake
58     - DeleteSample now removes all references to the deleted sample
59 persson 1301 - AddDimension now copies all parameters from existing dimension
60     regions and also makes sure that the samplechannel dimension is
61     placed first in the list of dimensions.
62 schoenebeck 1316 - added method GetParent() to class 'DimensionRegion', which returns its
63     parent Region
64 schoenebeck 1335 - fixed Instrument::UpdateRegionKeyTable() method which did not reset

336 schoenebeck 58 Version 0.7.0 (3 May 2004)
337    
338     * general changes:
339     - various big endian specific corrections
340     (successfully tested now on PPC)
341     - minor adjustments to avoid compile errors on some systems
342     (using now pow() instead of powl() and --pedantic g++ compiler switch)
343     - libtoolized the library
344     - added man pages for the command line tools
345     (gigextract, gigdump, dlsdump, rifftree)
346    
347     * src/gig.cpp, src/gig.h:
348     - fixed bug in decompression algorithm which caused it not to detect
349     the end of a stream
350     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
351     takes the MIDI key velocity value as an argument and returns the
352     appropriate volume factor (0.0 ... 1.0) for the sample to be played
353     back, the velocity curve transformation functions used for this are
354     only an approximation so far
355     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
356     'Sample::LoopSize' which reflected wrong values
357     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
358     measured in sample points instead of byte offset
359     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
360     'Sample::FineTune'
361     - added class attribute 'Sample::LoopSize'
362     - added method GetInstrument(uint index) to class 'File'
363     - added ReadAndLoop() method to class 'Sample' which is an extension to
364     the normal Read() method to honor the sample's looping information
365     while streaming from disk
366     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
367     'eg2_ctrl_t': replaced this huge enumeration by a structure which
368     reflects the MIDI controller number in case of an ordinary control
369     change controller (this saves a huge switch-case block in the
370     application of the library user)
371     - renamed following attributes in class 'DimensionRegion':
372     'AttenuationContol' -> 'AttenuationController',
373     'InvertAttenuationControl' -> 'InvertAttenuationController',
374     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
375     - minor fix in API documentation for method GetVelocityAttenuation() in
376     class 'DimensionRegion'
377    
378     * src/RIFF.cpp, src/RIFF.h:
379     - added additional API documentation
380     - minor fix in Chunk::Read() method (only a minor efficiency issue)
381    
382     * src/gigdump.cpp:
383     - added printout of samples' looping informations
384    
385 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
386    
387     * initial release
