File size: 18168 byte(s)
* bugfix: saving to the same file after the file size had been
  decreased sometimes made the file corrupt

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 - bugfix: saving to the same file after the file size had been
19 decreased sometimes also made the file corrupt!

21 Version 3.2.1 (5 Dec 2007)
22
23 * src/RIFF.cpp, src/RIFF.h:
24 - avoid Windows to perform unnecessary file stream caching which would
25 decrease disk streaming performance on Windows systems otherwise
26
27 * src/gig.cpp, src/gig.h:
28 - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
29 applications to retrieve very superficial informations like amount of
30 instruments and their names in a very fast way
31
32 Version 3.2.0 (14 Oct 2007)
33
34 * packaging changes:
35 - added Mac OSX XCode project files (patch by Toshi Nagata)
36 - Dev-C++ (win32) project file is automatically updated with
37 the version info from configure.in

41 * src/DLS.cpp, src/DLS.h:
42 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
43 - fixed write support for big-endian systems
44 - improved handling of fixed length info strings - separate default
45 lengths can be specified for each INFO chunk
46 - added Resource::GenerateDLSID function
47 - write support fix: allow regions without mapped samples
48 - added method SetKeyRange() to the Region class which should be used
49 instead of setting the KeyRange member variable directly
50 - MoveRegion() method of Region class is now private
51 - added SetGain() method to Sampler class
52 - fixed crash when saving a file after a sample loop was added
53
54 * src/gig.cpp, src/gig.h:
55 - fixed segmentation fault in the gig::File destructor sequence which
56 happened when gig::Group informations were accessed before
57 - fixed write support for big-endian systems
58 - defined lengths of a fixed set of info strings. These strings
59 are saved when the file is written, even if they are empty.
60 - added missing parameter initalizations in sample, region and
61 instrument constructors
62 - clear unused fields when saving samples and regions
63 - fixed write support bugs: v3 dimension limits and chunksize
64 weren't saved, leverage controller of type controlchange
65 couldn't be saved, group name list chunk was placed wrong,
66 dimension region chunks also placed wrong
67 - added initialization of some fixed info strings in file and
68 instrument
69 - write support: files created by libgig will now have the RIFF
70 chunks in correct order
71 - write support: two previously unknown fields in dimension
72 definition are now saved
73 - added constants for gig file versions

75 updated when a file is saved (3crc contains sample checksums,
76 einf contains file statistics)
77 - write support: DLSID is now generated on the file and the
78 instruments
79 - write support: improved the default values for dimension region
80 parameters
81 - more write support fixes: crossfade parameters were not saved,
82 v3 dimension limits were not correctly initialized and saved
83 when dimensions were added or deleted, v3 wave pool offsets were
84 not saved correctly
85 - write support: 24 bit samples can now be written
86 - write support: version 3 is now the default for new files
87 - more write support fixes: the 3ewg chunk is now bigger for v3,
88 dimension regions without mapped samples are now allowed, 3gnl
89 list in v3 files now always has 128 entries, several parameters
90 where incorrectly saved due to an operator precedence mistake
91 - DeleteSample now removes all references to the deleted sample
92 - AddDimension now copies all parameters from existing dimension
93 regions and also makes sure that the samplechannel dimension is
94 placed first in the list of dimensions.
95 - added method GetParent() to class 'DimensionRegion', which returns its
96 parent Region
97 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
98 unused areas
99 - added various setter methods to DimensionRegion class which take care
100 of updating lookup tables / caches.
101

108
109 Version 3.1.1 (24 Mar 2007)
110
111 * packaging changes:

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

273 (patch by Andreas Persson)
274 - added some file format compatibility checks
275 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

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

344 - added class attribute 'Layers' to class 'gig::Region'
345 - symbol prototyping of gig::Region (fixes build failure with qsampler)
346

360
361 * packaging changes:
362 - added libgig.spec and libgig.pc package configurations for generating
363 Redhat packages
364 - header files included on installation.
365 - autotools-generated files removed from CVS repository.
366 - added support for generating Debian packages
367 - version of shared library can be set in configure.in
368
369 Version 0.7.0 (3 May 2004)
370
371 * general changes:
372 - various big endian specific corrections
373 (successfully tested now on PPC)
374 - minor adjustments to avoid compile errors on some systems
375 (using now pow() instead of powl() and --pedantic g++ compiler switch)
376 - libtoolized the library
377 - added man pages for the command line tools
378 (gigextract, gigdump, dlsdump, rifftree)
379
380 * src/gig.cpp, src/gig.h:
381 - fixed bug in decompression algorithm which caused it not to detect
382 the end of a stream
383 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
384 takes the MIDI key velocity value as an argument and returns the
385 appropriate volume factor (0.0 ... 1.0) for the sample to be played
386 back, the velocity curve transformation functions used for this are
387 only an approximation so far
388 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
389 'Sample::LoopSize' which reflected wrong values
390 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
391 measured in sample points instead of byte offset
392 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
393 'Sample::FineTune'
394 - added class attribute 'Sample::LoopSize'
395 - added method GetInstrument(uint index) to class 'File'
396 - added ReadAndLoop() method to class 'Sample' which is an extension to
397 the normal Read() method to honor the sample's looping information
398 while streaming from disk
399 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
400 'eg2_ctrl_t': replaced this huge enumeration by a structure which
401 reflects the MIDI controller number in case of an ordinary control
402 change controller (this saves a huge switch-case block in the
403 application of the library user)
404 - renamed following attributes in class 'DimensionRegion':
405 'AttenuationContol' -> 'AttenuationController',
406 'InvertAttenuationControl' -> 'InvertAttenuationController',
407 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
408 - minor fix in API documentation for method GetVelocityAttenuation() in
409 class 'DimensionRegion'
410
411 * src/RIFF.cpp, src/RIFF.h:
412 - added additional API documentation
413 - minor fix in Chunk::Read() method (only a minor efficiency issue)
414
415 * src/gigdump.cpp:
416 - added printout of samples' looping informations
417
418 Version 0.6.0 (3 Nov 2003)
419
420 * initial release
