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

47     instrument constructors
48     - clear unused fields when saving samples and regions
49     - fixed write support bugs: v3 dimension limits and chunksize

62     einf contains file statistics)
63 persson 1209 - write support: DLSID is now generated on the file and the
64     instruments
65 persson 1218 - write support: improved the default values for dimension region
66     parameters
67 persson 1247 - more write support fixes: crossfade parameters were not saved,
68     v3 dimension limits were not correctly initialized and saved
69     when dimensions were added or deleted, v3 wave pool offsets were

71 persson 1264 - write support: 24 bit samples can now be written
72     - write support: version 3 is now the default for new files
73 persson 1266 - more write support fixes: the 3ewg chunk is now bigger for v3,
74     dimension regions without mapped samples are now allowed, 3gnl
75     list in v3 files now always has 128 entries, several parameters
76     where incorrectly saved due to an operator precedence mistake
77     - DeleteSample now removes all references to the deleted sample
78 persson 1301 - AddDimension now copies all parameters from existing dimension
79     regions and also makes sure that the samplechannel dimension is
80     placed first in the list of dimensions.
81 schoenebeck 1316 - added method GetParent() to class 'DimensionRegion', which returns its
82     parent Region
83 schoenebeck 1335 - fixed Instrument::UpdateRegionKeyTable() method which did not reset

88 persson 1183 * src/RIFF.cpp, src/RIFF.h:
89 persson 1184 - added File::SetByteOrder method

105     velocity (gig v3 feature)
106 persson 1076 - added "smart midi" and "round robin keyboard" dimensions
107 schoenebeck 1081 - added new method File::DeleteGroupOnly() which only deletes the given
108     group but moves all its members to another group, the other method,
109     that is File::DeleteGroup() now removes not just the group, but also
110     all the samples that belong to that group

261 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

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

345 capela 168 Version 0.7.1 (2 Jul 2004)
346    
347     * packaging changes:
348 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
349     Redhat packages
350 capela 168 - header files included on installation.
351     - autotools-generated files removed from CVS repository.
352 schoenebeck 186 - added support for generating Debian packages
353     - version of shared library can be set in configure.in
354    
355 schoenebeck 58 Version 0.7.0 (3 May 2004)
356    
357     * general changes:
358     - various big endian specific corrections
359     (successfully tested now on PPC)
360     - minor adjustments to avoid compile errors on some systems
361     (using now pow() instead of powl() and --pedantic g++ compiler switch)
362     - libtoolized the library
363     - added man pages for the command line tools
364     (gigextract, gigdump, dlsdump, rifftree)
365    
366     * src/gig.cpp, src/gig.h:
367     - fixed bug in decompression algorithm which caused it not to detect
368     the end of a stream
369     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
370     takes the MIDI key velocity value as an argument and returns the
371     appropriate volume factor (0.0 ... 1.0) for the sample to be played
372     back, the velocity curve transformation functions used for this are
373     only an approximation so far
374     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
375     'Sample::LoopSize' which reflected wrong values
376     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
377     measured in sample points instead of byte offset
378     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
379     'Sample::FineTune'
380     - added class attribute 'Sample::LoopSize'
381     - added method GetInstrument(uint index) to class 'File'
382     - added ReadAndLoop() method to class 'Sample' which is an extension to
383     the normal Read() method to honor the sample's looping information
384     while streaming from disk
385     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
386     'eg2_ctrl_t': replaced this huge enumeration by a structure which
387     reflects the MIDI controller number in case of an ordinary control
388     change controller (this saves a huge switch-case block in the
389     application of the library user)
390     - renamed following attributes in class 'DimensionRegion':
391     'AttenuationContol' -> 'AttenuationController',
392     'InvertAttenuationControl' -> 'InvertAttenuationController',
393     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
394     - minor fix in API documentation for method GetVelocityAttenuation() in
395     class 'DimensionRegion'
396    
397     * src/RIFF.cpp, src/RIFF.h:
398     - added additional API documentation
399     - minor fix in Chunk::Read() method (only a minor efficiency issue)
400    
401     * src/gigdump.cpp:
402     - added printout of samples' looping informations
403    
404 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
405    
406     * initial release
