1 schoenebeck 1549 Version 3.2.1 (5 Dec 2007)
2 schoenebeck 1459
3     * src/RIFF.cpp, src/RIFF.h:
4     - avoid Windows to perform unnecessary file stream caching which would
5     decrease disk streaming performance on Windows systems otherwise
6    
7 schoenebeck 1524 * src/gig.cpp, src/gig.h:
8     - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
9     applications to retrieve very superficial informations like amount of
10     instruments and their names in a very fast way
11    
12 schoenebeck 1416 Version 3.2.0 (14 Oct 2007)

26 persson 1209 - added Resource::GenerateDLSID function
27 persson 1266 - write support fix: allow regions without mapped samples
28 schoenebeck 1335 - added method SetKeyRange() to the Region class which should be used

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

41     instrument constructors
42     - clear unused fields when saving samples and regions
43     - fixed write support bugs: v3 dimension limits and chunksize

56     einf contains file statistics)
57 persson 1209 - write support: DLSID is now generated on the file and the
58     instruments
59 persson 1218 - write support: improved the default values for dimension region
60     parameters
61 persson 1247 - more write support fixes: crossfade parameters were not saved,

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

103     that is File::DeleteGroup() now removes not just the group, but also
104     all the samples that belong to that group

255 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

346 schoenebeck 186 - added support for generating Debian packages
347     - version of shared library can be set in configure.in
348    
349 schoenebeck 58 Version 0.7.0 (3 May 2004)
350    
351     * general changes:
352     - various big endian specific corrections
353     (successfully tested now on PPC)
354     - minor adjustments to avoid compile errors on some systems
355     (using now pow() instead of powl() and --pedantic g++ compiler switch)
356     - libtoolized the library
357     - added man pages for the command line tools
358     (gigextract, gigdump, dlsdump, rifftree)
359    
360     * src/gig.cpp, src/gig.h:
361     - fixed bug in decompression algorithm which caused it not to detect
362     the end of a stream
363     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
364     takes the MIDI key velocity value as an argument and returns the
365     appropriate volume factor (0.0 ... 1.0) for the sample to be played
366     back, the velocity curve transformation functions used for this are
367     only an approximation so far
368     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
369     'Sample::LoopSize' which reflected wrong values
370     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
371     measured in sample points instead of byte offset
372     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
373     'Sample::FineTune'
374     - added class attribute 'Sample::LoopSize'
375     - added method GetInstrument(uint index) to class 'File'
376     - added ReadAndLoop() method to class 'Sample' which is an extension to
377     the normal Read() method to honor the sample's looping information
378     while streaming from disk
379     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
380     'eg2_ctrl_t': replaced this huge enumeration by a structure which
381     reflects the MIDI controller number in case of an ordinary control
382     change controller (this saves a huge switch-case block in the
383     application of the library user)
384     - renamed following attributes in class 'DimensionRegion':
385     'AttenuationContol' -> 'AttenuationController',
386     'InvertAttenuationControl' -> 'InvertAttenuationController',
387     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
388     - minor fix in API documentation for method GetVelocityAttenuation() in
389     class 'DimensionRegion'
390    
391     * src/RIFF.cpp, src/RIFF.h:
392     - added additional API documentation
393     - minor fix in Chunk::Read() method (only a minor efficiency issue)
394    
395     * src/gigdump.cpp:
396     - added printout of samples' looping informations
397    
398 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
399    
400     * initial release
