* fixed compilation with gcc 4.3

1 Version CVS HEAD (?)
2
3 * general changes:
4 - fixed compilation with gcc 4.3
5
6 * src/gig.cpp, src/gig.h:
7 - added partial support for MIDI rules, only the Controller
8 Triggered rule is supported so far
9 - bugfix: removed another iterator invalidation in DeleteSample
10
11 * src/RIFF.cpp, src/RIFF.h:
12 - bugfix: saving to the same file after the file size had been
13 increased made the file corrupt (#82)
14
15 Version 3.2.1 (5 Dec 2007)
16
17 * src/RIFF.cpp, src/RIFF.h:
18 - avoid Windows to perform unnecessary file stream caching which would
19 decrease disk streaming performance on Windows systems otherwise
20
21 * src/gig.cpp, src/gig.h:
22 - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
23 applications to retrieve very superficial informations like amount of
24 instruments and their names in a very fast way
25
26 Version 3.2.0 (14 Oct 2007)
27
28 * packaging changes:
29 - added Mac OSX XCode project files (patch by Toshi Nagata)
30 - Dev-C++ (win32) project file is automatically updated with
31 the version info from configure.in

36 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
37 - fixed write support for big-endian systems
38 - improved handling of fixed length info strings - separate default
39 lengths can be specified for each INFO chunk
40 - added Resource::GenerateDLSID function
41 - write support fix: allow regions without mapped samples
42 - added method SetKeyRange() to the Region class which should be used
43 instead of setting the KeyRange member variable directly
44 - MoveRegion() method of Region class is now private
45 - added SetGain() method to Sampler class
46 - fixed crash when saving a file after a sample loop was added
47
48 * src/gig.cpp, src/gig.h:
49 - fixed segmentation fault in the gig::File destructor sequence which
50 happened when gig::Group informations were accessed before
51 - fixed write support for big-endian systems
52 - defined lengths of a fixed set of info strings. These strings
53 are saved when the file is written, even if they are empty.
54 - added missing parameter initalizations in sample, region and
55 instrument constructors
56 - clear unused fields when saving samples and regions
57 - fixed write support bugs: v3 dimension limits and chunksize
58 weren't saved, leverage controller of type controlchange
59 couldn't be saved, group name list chunk was placed wrong,
60 dimension region chunks also placed wrong
61 - added initialization of some fixed info strings in file and
62 instrument
63 - write support: files created by libgig will now have the RIFF
64 chunks in correct order
65 - write support: two previously unknown fields in dimension
66 definition are now saved
67 - added constants for gig file versions
68 - write support: the 3crc and einf chunks are now created or
69 updated when a file is saved (3crc contains sample checksums,
70 einf contains file statistics)
71 - write support: DLSID is now generated on the file and the
72 instruments
73 - write support: improved the default values for dimension region
74 parameters
75 - more write support fixes: crossfade parameters were not saved,
76 v3 dimension limits were not correctly initialized and saved
77 when dimensions were added or deleted, v3 wave pool offsets were
78 not saved correctly
79 - write support: 24 bit samples can now be written
80 - write support: version 3 is now the default for new files
81 - more write support fixes: the 3ewg chunk is now bigger for v3,
82 dimension regions without mapped samples are now allowed, 3gnl
83 list in v3 files now always has 128 entries, several parameters
84 where incorrectly saved due to an operator precedence mistake
85 - DeleteSample now removes all references to the deleted sample
86 - AddDimension now copies all parameters from existing dimension
87 regions and also makes sure that the samplechannel dimension is
88 placed first in the list of dimensions.
89 - added method GetParent() to class 'DimensionRegion', which returns its
90 parent Region
91 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
92 unused areas
93 - added various setter methods to DimensionRegion class which take care
94 of updating lookup tables / caches.
95
96 * src/RIFF.cpp, src/RIFF.h:
97 - added File::SetByteOrder method
98 - Windows fix: saving a new file didn't work

102
103 Version 3.1.1 (24 Mar 2007)
104
105 * packaging changes:

111 - custom velocity splits now works for gig v3 files too
112 - added support for custom splits points for other dimensions than
113 velocity (gig v3 feature)
114 - added "smart midi" and "round robin keyboard" dimensions
115 - added new method File::DeleteGroupOnly() which only deletes the given
116 group but moves all its members to another group, the other method,
117 that is File::DeleteGroup() now removes not just the group, but also
118 all the samples that belong to that group
119 - fixed crash which occured on interfering File::DeleteSample() and
120 File::GetNextSample() calls (due to iterator invalidation)
121 - fixed group names which were not saved
122 - fixed group destructor which did not remove the RIFF chunk associated
123 with the group
124 - added Instrument::MoveRegion method
125 - fixed constructor for Region, which did not initialize correctly
126 when used from Instrument::AddRegion
127 - when saving, override the gig::Regions sample reference simply by
128 the region's first dimension region's sample (avoids an exception
129 when trying to save a new instrument)
130 - fixed AddDimension() method which did not fill out all mandatory
131 dimension definition fields
132
133 * src/DLS.cpp, src/DLS.h:
134 - added Instrument::MoveRegion method
135 - fixed software info field which was wrongly stored on instruments,
136 causing an exception when trying to save a new instrument
137
138 * src/RIFF.cpp, src/RIFF.h:
139 - fixed RIFF::Chunk destructor which did not unregister previously
140 resized chunks, leading to a "zero size chunk" exception when
141 File::Save() was called
142 - added List::MoveSubChunk method
143
144 Version 3.1.0 (24 Nov 2006)

267 (patch by Andreas Persson)
268 - added some file format compatibility checks
269 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

319
320 * packaging changes:
321 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
322 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
323 - fixed man pages automake install rule (which didn't work on Mandrake,
324 SuSE and Fedora)
325 - fixed generation of Doxygen API documentation (now also included in
326 RPM and Debian packages)
327
328 * src/gig.cpp, src/gig.h:
329 - fixed / improved accuracy of all three velocity to volume
330 transformation functions a.k.a. 'nonlinear','linear','special'
331 (patch by Andreas Persson)
332 - denormals are filtered from the velocity to volume tables
333 - bugfix for dimension region switching (wrong handling of the release
334 trigger dimension, no bit range check for dimensions of split type
335 'split_type_bit')

338 - added class attribute 'Layers' to class 'gig::Region'
339 - symbol prototyping of gig::Region (fixes build failure with qsampler)
340

353 Version 0.7.1 (2 Jul 2004)
354
355 * packaging changes:
356 - added libgig.spec and libgig.pc package configurations for generating
357 Redhat packages
358 - header files included on installation.
359 - autotools-generated files removed from CVS repository.
360 - added support for generating Debian packages
361 - version of shared library can be set in configure.in
362
363 Version 0.7.0 (3 May 2004)
364
365 * general changes:
366 - various big endian specific corrections
367 (successfully tested now on PPC)
368 - minor adjustments to avoid compile errors on some systems
369 (using now pow() instead of powl() and --pedantic g++ compiler switch)
370 - libtoolized the library
371 - added man pages for the command line tools
372 (gigextract, gigdump, dlsdump, rifftree)
373
374 * src/gig.cpp, src/gig.h:
375 - fixed bug in decompression algorithm which caused it not to detect
376 the end of a stream
377 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
378 takes the MIDI key velocity value as an argument and returns the
379 appropriate volume factor (0.0 ... 1.0) for the sample to be played
380 back, the velocity curve transformation functions used for this are
381 only an approximation so far
382 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
383 'Sample::LoopSize' which reflected wrong values
384 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
385 measured in sample points instead of byte offset
386 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
387 'Sample::FineTune'
388 - added class attribute 'Sample::LoopSize'
389 - added method GetInstrument(uint index) to class 'File'
390 - added ReadAndLoop() method to class 'Sample' which is an extension to
391 the normal Read() method to honor the sample's looping information
392 while streaming from disk
393 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
394 'eg2_ctrl_t': replaced this huge enumeration by a structure which
395 reflects the MIDI controller number in case of an ordinary control
396 change controller (this saves a huge switch-case block in the
397 application of the library user)
398 - renamed following attributes in class 'DimensionRegion':
399 'AttenuationContol' -> 'AttenuationController',
400 'InvertAttenuationControl' -> 'InvertAttenuationController',
401 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
402 - minor fix in API documentation for method GetVelocityAttenuation() in
403 class 'DimensionRegion'
404
405 * src/RIFF.cpp, src/RIFF.h:
406 - added additional API documentation
407 - minor fix in Chunk::Read() method (only a minor efficiency issue)
408
409 * src/gigdump.cpp:
410 - added printout of samples' looping informations
411
412 Version 0.6.0 (3 Nov 2003)
413
414 * initial release
