14     lengths can be specified for each INFO chunk
15 persson 1209 - added Resource::GenerateDLSID function
16 persson 1266 - write support fix: allow regions without mapped samples
17 schoenebeck 1335 - added method SetKeyRange() to the Region class which should be used
18     instead of setting the KeyRange member variable directly
19     - MoveRegion() method of Region class is now private

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

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

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

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

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

71 persson 1184 - added File::SetByteOrder method

89 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
90     group but moves all its members to another group, the other method,
91     that is File::DeleteGroup() now removes not just the group, but also
92     all the samples that belong to that group

242 schoenebeck 317 - added some file format compatibility checks
243 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

327 capela 168 Version 0.7.1 (2 Jul 2004)
328    
329     * packaging changes:
330 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
331     Redhat packages

333     - autotools-generated files removed from CVS repository.
334 schoenebeck 186 - added support for generating Debian packages
335     - version of shared library can be set in configure.in
336    
337 schoenebeck 58 Version 0.7.0 (3 May 2004)
338    
339     * general changes:
340     - various big endian specific corrections
341     (successfully tested now on PPC)
342     - minor adjustments to avoid compile errors on some systems
343     (using now pow() instead of powl() and --pedantic g++ compiler switch)
344     - libtoolized the library
345     - added man pages for the command line tools
346     (gigextract, gigdump, dlsdump, rifftree)
347    
348     * src/gig.cpp, src/gig.h:
349     - fixed bug in decompression algorithm which caused it not to detect
350     the end of a stream
351     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
352     takes the MIDI key velocity value as an argument and returns the
353     appropriate volume factor (0.0 ... 1.0) for the sample to be played
354     back, the velocity curve transformation functions used for this are
355     only an approximation so far
356     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
357     'Sample::LoopSize' which reflected wrong values
358     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
359     measured in sample points instead of byte offset
360     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
361     'Sample::FineTune'
362     - added class attribute 'Sample::LoopSize'
363     - added method GetInstrument(uint index) to class 'File'
364     - added ReadAndLoop() method to class 'Sample' which is an extension to
365     the normal Read() method to honor the sample's looping information
366     while streaming from disk
367     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
368     'eg2_ctrl_t': replaced this huge enumeration by a structure which
369     reflects the MIDI controller number in case of an ordinary control
370     change controller (this saves a huge switch-case block in the
371     application of the library user)
372     - renamed following attributes in class 'DimensionRegion':
373     'AttenuationContol' -> 'AttenuationController',
374     'InvertAttenuationControl' -> 'InvertAttenuationController',
375     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
376     - minor fix in API documentation for method GetVelocityAttenuation() in
377     class 'DimensionRegion'
378    
379     * src/RIFF.cpp, src/RIFF.h:
380     - added additional API documentation
381     - minor fix in Chunk::Read() method (only a minor efficiency issue)
382    
383     * src/gigdump.cpp:
384     - added printout of samples' looping informations
385    
386 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
387    
388     * initial release
