File size: 16796 byte(s)
* added various setter methods to which take care of updating
  lookup tables / caches

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - added Mac OSX XCode project files (patch by Toshi Nagata)
5 - Dev-C++ (win32) project file is automatically updated with
6 the version info from configure.in
7 - the configure script can now be used in Windows with MSYS
8
9 * src/DLS.cpp, src/DLS.h:
10 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
11 - fixed write support for big-endian systems
12 - improved handling of fixed length info strings - separate default
13 lengths can be specified for each INFO chunk
14 - added Resource::GenerateDLSID function
15 - write support fix: allow regions without mapped samples
16 - added method SetKeyRange() to the Region class which should be used
17 instead of setting the KeyRange member variable directly
18 - MoveRegion() method of Region class is now private
19 - added SetGain() method to Sampler class
20
21 * src/gig.cpp, src/gig.h:
22 - fixed segmentation fault in the gig::File destructor sequence which
23 happened when gig::Group informations were accessed before
24 - fixed write support for big-endian systems
25 - defined lengths of a fixed set of info strings. These strings
26 are saved when the file is written, even if they are empty.
27 - 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
31 weren't saved, leverage controller of type controlchange
32 couldn't be saved, group name list chunk was placed wrong,
33 dimension region chunks also placed wrong
34 - added initialization of some fixed info strings in file and
35 instrument
36 - write support: files created by libgig will now have the RIFF
37 chunks in correct order
38 - write support: two previously unknown fields in dimension
39 definition are now saved
40 - added constants for gig file versions
41 - write support: the 3crc and einf chunks are now created or
42 updated when a file is saved (3crc contains sample checksums,
43 einf contains file statistics)
44 - write support: DLSID is now generated on the file and the
45 instruments
46 - write support: improved the default values for dimension region
47 parameters
48 - 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
52 - write support: 24 bit samples can now be written
53 - write support: version 3 is now the default for new files
54 - 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 - 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 - added method GetParent() to class 'DimensionRegion', which returns its
63 parent Region
64 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
65 unused areas
66 - added various setter methods to DimensionRegion class which take care
67 of updating lookup tables / caches.
68
69 * src/RIFF.cpp, src/RIFF.h:
70 - added File::SetByteOrder method
71 - Windows fix: saving a new file didn't work
72
73 * src/gigdump.cpp:
74 - added some missing dimension strings
75
76 Version 3.1.1 (24 Mar 2007)
77
78 * packaging changes:
79 - ported to Windows using native Windows functions for file IO
80 (provided Dev-C++ + mingw project file)
81 - only export relevant files to Doxygen API documentation
82
83 * src/gig.cpp, src/gig.h:
84 - custom velocity splits now works for gig v3 files too
85 - added support for custom splits points for other dimensions than
86 velocity (gig v3 feature)
87 - added "smart midi" and "round robin keyboard" dimensions
88 - added new method File::DeleteGroupOnly() which only deletes the given
89 group but moves all its members to another group, the other method,
90 that is File::DeleteGroup() now removes not just the group, but also
91 all the samples that belong to that group
92 - fixed crash which occured on interfering File::DeleteSample() and
93 File::GetNextSample() calls (due to iterator invalidation)
94 - fixed group names which were not saved
95 - fixed group destructor which did not remove the RIFF chunk associated
96 with the group
97 - added Instrument::MoveRegion method
98 - fixed constructor for Region, which did not initialize correctly
99 when used from Instrument::AddRegion
100 - when saving, override the gig::Regions sample reference simply by
101 the region's first dimension region's sample (avoids an exception
102 when trying to save a new instrument)
103 - fixed AddDimension() method which did not fill out all mandatory
104 dimension definition fields
105
106 * src/DLS.cpp, src/DLS.h:
107 - added Instrument::MoveRegion method
108 - fixed software info field which was wrongly stored on instruments,
109 causing an exception when trying to save a new instrument
110
111 * src/RIFF.cpp, src/RIFF.h:
112 - fixed RIFF::Chunk destructor which did not unregister previously
113 resized chunks, leading to a "zero size chunk" exception when
114 File::Save() was called
115 - added List::MoveSubChunk method
116
117 Version 3.1.0 (24 Nov 2006)

239 articulation informations are ignored at the moment
240 (patch by Andreas Persson)
241 - added some file format compatibility checks
242 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

292
293 * packaging changes:
294 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
295 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
296 - fixed man pages automake install rule (which didn't work on Mandrake,
297 SuSE and Fedora)
298 - fixed generation of Doxygen API documentation (now also included in
299 RPM and Debian packages)
300
301 * src/gig.cpp, src/gig.h:
302 - fixed / improved accuracy of all three velocity to volume
303 transformation functions a.k.a. 'nonlinear','linear','special'
304 (patch by Andreas Persson)
305 - denormals are filtered from the velocity to volume tables
306 - bugfix for dimension region switching (wrong handling of the release
307 trigger dimension, no bit range check for dimensions of split type
308 'split_type_bit')

311 - added class attribute 'Layers' to class 'gig::Region'
312 - symbol prototyping of gig::Region (fixes build failure with qsampler)
313

325
326 Version 0.7.1 (2 Jul 2004)
327
328 * packaging changes:
329 - added libgig.spec and libgig.pc package configurations for generating
330 Redhat packages
331 - header files included on installation.
332 - autotools-generated files removed from CVS repository.
333 - added support for generating Debian packages
334 - version of shared library can be set in configure.in
335
336 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 Version 0.6.0 (3 Nov 2003)
386
387 * initial release
