File size: 16632 byte(s)
* added virtual method SetKeyRange() to the gig and DLS Region classes,
  which automatically take care that the "resized" Region is at the
  correct position and that the lookup table for
  gig::Instrument::GetRegion() is updated (moved code from gigedit)
* MoveRegion() method of DLS::Region class is now private
* bugfix: gig::Instrument::UpdateRegionKeyTable() did not reset unused
  areas

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
20 * src/gig.cpp, src/gig.h:
21 - fixed segmentation fault in the gig::File destructor sequence which
22 happened when gig::Group informations were accessed before
23 - fixed write support for big-endian systems
24 - defined lengths of a fixed set of info strings. These strings
25 are saved when the file is written, even if they are empty.
26 - added missing parameter initalizations in sample, region and
27 instrument constructors
28 - clear unused fields when saving samples and regions
29 - fixed write support bugs: v3 dimension limits and chunksize
30 weren't saved, leverage controller of type controlchange
31 couldn't be saved, group name list chunk was placed wrong,
32 dimension region chunks also placed wrong
33 - added initialization of some fixed info strings in file and
34 instrument
35 - write support: files created by libgig will now have the RIFF
36 chunks in correct order
37 - write support: two previously unknown fields in dimension
38 definition are now saved
39 - added constants for gig file versions
40 - write support: the 3crc and einf chunks are now created or
41 updated when a file is saved (3crc contains sample checksums,
42 einf contains file statistics)
43 - write support: DLSID is now generated on the file and the
44 instruments
45 - write support: improved the default values for dimension region
46 parameters
47 - more write support fixes: crossfade parameters were not saved,
48 v3 dimension limits were not correctly initialized and saved
49 when dimensions were added or deleted, v3 wave pool offsets were
50 not saved correctly
51 - write support: 24 bit samples can now be written
52 - write support: version 3 is now the default for new files
53 - more write support fixes: the 3ewg chunk is now bigger for v3,
54 dimension regions without mapped samples are now allowed, 3gnl
55 list in v3 files now always has 128 entries, several parameters
56 where incorrectly saved due to an operator precedence mistake
57 - DeleteSample now removes all references to the deleted sample
58 - AddDimension now copies all parameters from existing dimension
59 regions and also makes sure that the samplechannel dimension is
60 placed first in the list of dimensions.
61 - added method GetParent() to class 'DimensionRegion', which returns its
62 parent Region
63 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
64 unused areas
65
66 * src/RIFF.cpp, src/RIFF.h:
67 - added File::SetByteOrder method
68 - Windows fix: saving a new file didn't work
69
70 * src/gigdump.cpp:
71 - added some missing dimension strings
72
73 Version 3.1.1 (24 Mar 2007)
74
75 * packaging changes:
76 - ported to Windows using native Windows functions for file IO
77 (provided Dev-C++ + mingw project file)
78 - only export relevant files to Doxygen API documentation
79
80 * src/gig.cpp, src/gig.h:
81 - custom velocity splits now works for gig v3 files too
82 - added support for custom splits points for other dimensions than
83 velocity (gig v3 feature)
84 - added "smart midi" and "round robin keyboard" dimensions
85 - added new method File::DeleteGroupOnly() which only deletes the given
86 group but moves all its members to another group, the other method,
87 that is File::DeleteGroup() now removes not just the group, but also
88 all the samples that belong to that group
89 - fixed crash which occured on interfering File::DeleteSample() and
90 File::GetNextSample() calls (due to iterator invalidation)
91 - fixed group names which were not saved
92 - fixed group destructor which did not remove the RIFF chunk associated
93 with the group
94 - added Instrument::MoveRegion method
95 - fixed constructor for Region, which did not initialize correctly
96 when used from Instrument::AddRegion
97 - when saving, override the gig::Regions sample reference simply by
98 the region's first dimension region's sample (avoids an exception
99 when trying to save a new instrument)
100 - fixed AddDimension() method which did not fill out all mandatory
101 dimension definition fields
102
103 * src/DLS.cpp, src/DLS.h:
104 - added Instrument::MoveRegion method
105 - fixed software info field which was wrongly stored on instruments,
106 causing an exception when trying to save a new instrument
107
108 * src/RIFF.cpp, src/RIFF.h:
109 - fixed RIFF::Chunk destructor which did not unregister previously
110 resized chunks, leading to a "zero size chunk" exception when
111 File::Save() was called
112 - added List::MoveSubChunk method
113

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

289
290 * packaging changes:
291 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
292 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
293 - fixed man pages automake install rule (which didn't work on Mandrake,
294 SuSE and Fedora)
295 - fixed generation of Doxygen API documentation (now also included in
296 RPM and Debian packages)
297
298 * src/gig.cpp, src/gig.h:
299 - fixed / improved accuracy of all three velocity to volume
300 transformation functions a.k.a. 'nonlinear','linear','special'
301 (patch by Andreas Persson)
302 - denormals are filtered from the velocity to volume tables
303 - bugfix for dimension region switching (wrong handling of the release
304 trigger dimension, no bit range check for dimensions of split type
305 'split_type_bit')
306 - fixed panorama value in DimensionRegion (invalid conversion from
307 signed 7 bit to signed 8 bit)
308 - added class attribute 'Layers' to class 'gig::Region'
309 - symbol prototyping of gig::Region (fixes build failure with qsampler)
310
311 * src/gigextract.cpp:

322
323 Version 0.7.1 (2 Jul 2004)
324
325 * packaging changes:
326 - added libgig.spec and libgig.pc package configurations for generating
327 Redhat packages
328 - header files included on installation.
329 - autotools-generated files removed from CVS repository.
330 - added support for generating Debian packages
331 - version of shared library can be set in configure.in
332
333 Version 0.7.0 (3 May 2004)
334
335 * general changes:
336 - various big endian specific corrections
337 (successfully tested now on PPC)
338 - minor adjustments to avoid compile errors on some systems
339 (using now pow() instead of powl() and --pedantic g++ compiler switch)
340 - libtoolized the library
341 - added man pages for the command line tools
342 (gigextract, gigdump, dlsdump, rifftree)
343
344 * src/gig.cpp, src/gig.h:
345 - fixed bug in decompression algorithm which caused it not to detect
346 the end of a stream
347 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
348 takes the MIDI key velocity value as an argument and returns the
349 appropriate volume factor (0.0 ... 1.0) for the sample to be played
350 back, the velocity curve transformation functions used for this are
351 only an approximation so far
352 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
353 'Sample::LoopSize' which reflected wrong values
354 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
355 measured in sample points instead of byte offset
356 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
357 'Sample::FineTune'
358 - added class attribute 'Sample::LoopSize'
359 - added method GetInstrument(uint index) to class 'File'
360 - added ReadAndLoop() method to class 'Sample' which is an extension to
361 the normal Read() method to honor the sample's looping information
362 while streaming from disk
363 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
364 'eg2_ctrl_t': replaced this huge enumeration by a structure which
365 reflects the MIDI controller number in case of an ordinary control
366 change controller (this saves a huge switch-case block in the
367 application of the library user)
368 - renamed following attributes in class 'DimensionRegion':
369 'AttenuationContol' -> 'AttenuationController',
370 'InvertAttenuationControl' -> 'InvertAttenuationController',
371 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
372 - minor fix in API documentation for method GetVelocityAttenuation() in
373 class 'DimensionRegion'
374
375 * src/RIFF.cpp, src/RIFF.h:
376 - added additional API documentation
377 - minor fix in Chunk::Read() method (only a minor efficiency issue)
378
379 * src/gigdump.cpp:
380 - added printout of samples' looping informations
381
382 Version 0.6.0 (3 Nov 2003)
383
384 * initial release
