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
20 schoenebeck 1358 - added SetGain() method to Sampler class
21 persson 1388 - fixed crash when saving a file after a sample loop was added

25     happened when gig::Group informations were accessed before
26 persson 1179 - fixed write support for big-endian systems
27 persson 1180 - defined lengths of a fixed set of info strings. These strings
28     are saved when the file is written, even if they are empty.
29 persson 1182 - added missing parameter initalizations in sample, region and
30     instrument constructors
31     - clear unused fields when saving samples and regions
32     - fixed write support bugs: v3 dimension limits and chunksize
33     weren't saved, leverage controller of type controlchange
34 persson 1195 couldn't be saved, group name list chunk was placed wrong,
35     dimension region chunks also placed wrong
36 persson 1182 - added initialization of some fixed info strings in file and
37     instrument
38 persson 1192 - write support: files created by libgig will now have the RIFF

41     definition are now saved
42     - added constants for gig file versions
43     - write support: the 3crc and einf chunks are now created or
44     updated when a file is saved (3crc contains sample checksums,
45     einf contains file statistics)
46 persson 1209 - write support: DLSID is now generated on the file and the
47     instruments
48 persson 1218 - write support: improved the default values for dimension region
49     parameters
50 persson 1247 - more write support fixes: crossfade parameters were not saved,
51     v3 dimension limits were not correctly initialized and saved
52     when dimensions were added or deleted, v3 wave pool offsets were
53     not saved correctly
54 persson 1264 - write support: 24 bit samples can now be written
55     - write support: version 3 is now the default for new files
56 persson 1266 - more write support fixes: the 3ewg chunk is now bigger for v3,
57     dimension regions without mapped samples are now allowed, 3gnl
58     list in v3 files now always has 128 entries, several parameters
59     where incorrectly saved due to an operator precedence mistake
60     - DeleteSample now removes all references to the deleted sample
61 persson 1301 - AddDimension now copies all parameters from existing dimension
62     regions and also makes sure that the samplechannel dimension is
63     placed first in the list of dimensions.
64 schoenebeck 1316 - added method GetParent() to class 'DimensionRegion', which returns its
65     parent Region
66 schoenebeck 1335 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
67     unused areas

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

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

243 schoenebeck 317 - added some file format compatibility checks
244 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
245     never used, because the necessary check was made before

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

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

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

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