File size: 18047 byte(s)
* bugfix: refuse RIFF::Chunk::Read() in case chunk has just been added,
  that is not written physically yet (#82)
* bugfix in gig::Sample::LoadSampleData*(): reset sample read position
  to sample start before trying to (re)load sample data from file (#82)

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 - bugfix in Sample::LoadSampleData*(): reset sample read position to
11 sample start before trying to (re)load sample data from file (#82)
12
13 * src/RIFF.cpp, src/RIFF.h:
14 - bugfix: saving to the same file after the file size had been
15 increased made the file corrupt (#82)
16 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
17 is not written physically yet (#82)
18
19 Version 3.2.1 (5 Dec 2007)
20
21 * src/RIFF.cpp, src/RIFF.h:
22 - avoid Windows to perform unnecessary file stream caching which would
23 decrease disk streaming performance on Windows systems otherwise
24
25 * src/gig.cpp, src/gig.h:
26 - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
27 applications to retrieve very superficial informations like amount of
28 instruments and their names in a very fast way
29
30 Version 3.2.0 (14 Oct 2007)
31
32 * packaging changes:
33 - added Mac OSX XCode project files (patch by Toshi Nagata)
34 - Dev-C++ (win32) project file is automatically updated with
35 the version info from configure.in

40 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
41 - fixed write support for big-endian systems
42 - improved handling of fixed length info strings - separate default
43 lengths can be specified for each INFO chunk
44 - added Resource::GenerateDLSID function
45 - write support fix: allow regions without mapped samples
46 - added method SetKeyRange() to the Region class which should be used
47 instead of setting the KeyRange member variable directly
48 - MoveRegion() method of Region class is now private
49 - added SetGain() method to Sampler class
50 - fixed crash when saving a file after a sample loop was added
51
52 * src/gig.cpp, src/gig.h:
53 - fixed segmentation fault in the gig::File destructor sequence which
54 happened when gig::Group informations were accessed before
55 - fixed write support for big-endian systems
56 - defined lengths of a fixed set of info strings. These strings
57 are saved when the file is written, even if they are empty.
58 - added missing parameter initalizations in sample, region and
59 instrument constructors
60 - clear unused fields when saving samples and regions
61 - fixed write support bugs: v3 dimension limits and chunksize
62 weren't saved, leverage controller of type controlchange
63 couldn't be saved, group name list chunk was placed wrong,
64 dimension region chunks also placed wrong
65 - added initialization of some fixed info strings in file and
66 instrument
67 - write support: files created by libgig will now have the RIFF
68 chunks in correct order
69 - write support: two previously unknown fields in dimension
70 definition are now saved
71 - added constants for gig file versions
72 - write support: the 3crc and einf chunks are now created or
73 updated when a file is saved (3crc contains sample checksums,
74 einf contains file statistics)
75 - write support: DLSID is now generated on the file and the
76 instruments
77 - write support: improved the default values for dimension region
78 parameters
79 - more write support fixes: crossfade parameters were not saved,
80 v3 dimension limits were not correctly initialized and saved
81 when dimensions were added or deleted, v3 wave pool offsets were
82 not saved correctly
83 - write support: 24 bit samples can now be written
84 - write support: version 3 is now the default for new files
85 - more write support fixes: the 3ewg chunk is now bigger for v3,
86 dimension regions without mapped samples are now allowed, 3gnl
87 list in v3 files now always has 128 entries, several parameters
88 where incorrectly saved due to an operator precedence mistake
89 - DeleteSample now removes all references to the deleted sample
90 - AddDimension now copies all parameters from existing dimension
91 regions and also makes sure that the samplechannel dimension is
92 placed first in the list of dimensions.
93 - added method GetParent() to class 'DimensionRegion', which returns its
94 parent Region
95 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
96 unused areas
97 - added various setter methods to DimensionRegion class which take care
98 of updating lookup tables / caches.
99
100 * src/RIFF.cpp, src/RIFF.h:
101 - added File::SetByteOrder method

106
107 Version 3.1.1 (24 Mar 2007)
108
109 * packaging changes:

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

270 articulation informations are ignored at the moment
271 (patch by Andreas Persson)
272 - added some file format compatibility checks
273 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

341 signed 7 bit to signed 8 bit)
342 - added class attribute 'Layers' to class 'gig::Region'
343 - symbol prototyping of gig::Region (fixes build failure with qsampler)
344

357 Version 0.7.1 (2 Jul 2004)
358
359 * packaging changes:
360 - added libgig.spec and libgig.pc package configurations for generating
361 Redhat packages
362 - header files included on installation.
363 - autotools-generated files removed from CVS repository.
364 - added support for generating Debian packages
365 - version of shared library can be set in configure.in
366
367 Version 0.7.0 (3 May 2004)
368
369 * general changes:
370 - various big endian specific corrections
371 (successfully tested now on PPC)
372 - minor adjustments to avoid compile errors on some systems
373 (using now pow() instead of powl() and --pedantic g++ compiler switch)
374 - libtoolized the library
375 - added man pages for the command line tools
376 (gigextract, gigdump, dlsdump, rifftree)
377
378 * src/gig.cpp, src/gig.h:
379 - fixed bug in decompression algorithm which caused it not to detect
380 the end of a stream
381 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
382 takes the MIDI key velocity value as an argument and returns the
383 appropriate volume factor (0.0 ... 1.0) for the sample to be played
384 back, the velocity curve transformation functions used for this are
385 only an approximation so far
386 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
387 'Sample::LoopSize' which reflected wrong values
388 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
389 measured in sample points instead of byte offset
390 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
391 'Sample::FineTune'
392 - added class attribute 'Sample::LoopSize'
393 - added method GetInstrument(uint index) to class 'File'
394 - added ReadAndLoop() method to class 'Sample' which is an extension to
395 the normal Read() method to honor the sample's looping information
396 while streaming from disk
397 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
398 'eg2_ctrl_t': replaced this huge enumeration by a structure which
399 reflects the MIDI controller number in case of an ordinary control
400 change controller (this saves a huge switch-case block in the
401 application of the library user)
402 - renamed following attributes in class 'DimensionRegion':
403 'AttenuationContol' -> 'AttenuationController',
404 'InvertAttenuationControl' -> 'InvertAttenuationController',
405 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
406 - minor fix in API documentation for method GetVelocityAttenuation() in
407 class 'DimensionRegion'
408
409 * src/RIFF.cpp, src/RIFF.h:
410 - added additional API documentation
411 - minor fix in Chunk::Read() method (only a minor efficiency issue)
412
413 * src/gigdump.cpp:
414 - added printout of samples' looping informations
415
416 Version 0.6.0 (3 Nov 2003)
417
418 * initial release
