* fixed crash when saving a file after a sample loop was added

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 - added a mainpage for the Doxygen API documentation
9
10 * src/DLS.cpp, src/DLS.h:
11 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
12 - fixed write support for big-endian systems
13 - improved handling of fixed length info strings - separate default
14 lengths can be specified for each INFO chunk
15 - added Resource::GenerateDLSID function
16 - write support fix: allow regions without mapped samples
17 - 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 - added SetGain() method to Sampler class
21 - fixed crash when saving a file after a sample loop was added
22
23 * src/gig.cpp, src/gig.h:
24 - fixed segmentation fault in the gig::File destructor sequence which
25 happened when gig::Group informations were accessed before
26 - fixed write support for big-endian systems
27 - 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 - 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 couldn't be saved, group name list chunk was placed wrong,
35 dimension region chunks also placed wrong
36 - added initialization of some fixed info strings in file and
37 instrument
38 - write support: files created by libgig will now have the RIFF
39 chunks in correct order
40 - write support: two previously unknown fields in dimension
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 - write support: DLSID is now generated on the file and the
47 instruments
48 - write support: improved the default values for dimension region
49 parameters
50 - 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 - write support: 24 bit samples can now be written
55 - write support: version 3 is now the default for new files
56 - 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 - 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 - added method GetParent() to class 'DimensionRegion', which returns its
65 parent Region
66 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
67 unused areas
68 - added various setter methods to DimensionRegion class which take care
69 of updating lookup tables / caches.
70
71 * src/RIFF.cpp, src/RIFF.h:
72 - added File::SetByteOrder method
73 - Windows fix: saving a new file didn't work
74
75 * src/gigdump.cpp:
76 - added some missing dimension strings
77
78 Version 3.1.1 (24 Mar 2007)
79
80 * packaging changes:
81 - ported to Windows using native Windows functions for file IO
82 (provided Dev-C++ + mingw project file)

84
85 * src/gig.cpp, src/gig.h:
86 - custom velocity splits now works for gig v3 files too
87 - added support for custom splits points for other dimensions than
88 velocity (gig v3 feature)
89 - added "smart midi" and "round robin keyboard" dimensions
90 - 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
94 - fixed crash which occured on interfering File::DeleteSample() and
95 File::GetNextSample() calls (due to iterator invalidation)
96 - fixed group names which were not saved
97 - fixed group destructor which did not remove the RIFF chunk associated
98 with the group
99 - added Instrument::MoveRegion method
100 - fixed constructor for Region, which did not initialize correctly
101 when used from Instrument::AddRegion
102 - when saving, override the gig::Regions sample reference simply by
103 the region's first dimension region's sample (avoids an exception
104 when trying to save a new instrument)
105 - fixed AddDimension() method which did not fill out all mandatory
106 dimension definition fields
107
108 * src/DLS.cpp, src/DLS.h:
109 - added Instrument::MoveRegion method
110 - fixed software info field which was wrongly stored on instruments,
111 causing an exception when trying to save a new instrument
112
113 * src/RIFF.cpp, src/RIFF.h:
114 - fixed RIFF::Chunk destructor which did not unregister previously
115 resized chunks, leading to a "zero size chunk" exception when
116 File::Save() was called
117 - added List::MoveSubChunk method
118

242 (patch by Andreas Persson)
243 - added some file format compatibility checks
244 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

314 - symbol prototyping of gig::Region (fixes build failure with qsampler)
315

328 Version 0.7.1 (2 Jul 2004)
329
330 * packaging changes:
331 - added libgig.spec and libgig.pc package configurations for generating
332 Redhat packages
333 - header files included on installation.
334 - autotools-generated files removed from CVS repository.
335 - added support for generating Debian packages
336 - version of shared library can be set in configure.in
337
338 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 Version 0.6.0 (3 Nov 2003)
388
389 * initial release
