Thu Mar 26 13:32:59 2009 UTC (11 years, 6 months ago) by schoenebeck
File size: 18706 byte(s)
* fixed crash which occured when streaming a gig sample with
  bi-directional (a.k.a. 'pingpong') loop type (fixes #102)

1 Version CVS HEAD (?)
2
3 * general changes:
4 - fixed compilation with gcc 4.3
5 - fixes for building with Visual C++
6
7 * src/gig.cpp, src/gig.h:
8 - added partial support for MIDI rules, only the Controller
9 Triggered rule is supported so far
10 - bugfix: removed another iterator invalidation in DeleteSample
11 - bugfix in Sample::LoadSampleData*(): reset sample read position to
12 sample start before trying to (re)load sample data from file (#82)
13 - bugfix: EG3 depth parameter was not saved correctly
14 - fixed crash which occured when streaming a gig sample with
15 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
16
17 * src/RIFF.cpp, src/RIFF.h:
18 - bugfix: saving to the same file after the file size had been
19 increased made the file corrupt (#82)
20 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
21 is not written physically yet (#82)
22 - bugfix: saving to the same file after the file size had been
23 decreased sometimes also made the file corrupt!
24 - bugfix: undefined behavior (e.g. endless loop) when opening zero
25 length files, now throws a RIFF::Exception instead (fixes bug #121)
26 - bugfix: destructor for base class RIFF::Chunk accessed members
27 of derived class RIFF::File, which is bad, and caused crashes
28 when using Visual C++
29
30 Version 3.2.1 (5 Dec 2007)
31
32 * src/RIFF.cpp, src/RIFF.h:
33 - avoid Windows to perform unnecessary file stream caching which would
34 decrease disk streaming performance on Windows systems otherwise
35
36 * src/gig.cpp, src/gig.h:
37 - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
38 applications to retrieve very superficial informations like amount of
39 instruments and their names in a very fast way
40
41 Version 3.2.0 (14 Oct 2007)
42
43 * packaging changes:
44 - added Mac OSX XCode project files (patch by Toshi Nagata)
45 - Dev-C++ (win32) project file is automatically updated with
46 the version info from configure.in

51 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
52 - fixed write support for big-endian systems
53 - improved handling of fixed length info strings - separate default
54 lengths can be specified for each INFO chunk
55 - added Resource::GenerateDLSID function
56 - write support fix: allow regions without mapped samples
57 - added method SetKeyRange() to the Region class which should be used
58 instead of setting the KeyRange member variable directly
59 - MoveRegion() method of Region class is now private
60 - added SetGain() method to Sampler class
61 - fixed crash when saving a file after a sample loop was added
62
63 * src/gig.cpp, src/gig.h:
64 - fixed segmentation fault in the gig::File destructor sequence which
65 happened when gig::Group informations were accessed before
66 - fixed write support for big-endian systems
67 - defined lengths of a fixed set of info strings. These strings
68 are saved when the file is written, even if they are empty.
69 - added missing parameter initalizations in sample, region and
70 instrument constructors
71 - clear unused fields when saving samples and regions
72 - fixed write support bugs: v3 dimension limits and chunksize
73 weren't saved, leverage controller of type controlchange
74 couldn't be saved, group name list chunk was placed wrong,
75 dimension region chunks also placed wrong
76 - added initialization of some fixed info strings in file and
77 instrument
78 - write support: files created by libgig will now have the RIFF
79 chunks in correct order
80 - write support: two previously unknown fields in dimension
81 definition are now saved
82 - added constants for gig file versions
83 - write support: the 3crc and einf chunks are now created or
84 updated when a file is saved (3crc contains sample checksums,
85 einf contains file statistics)
86 - write support: DLSID is now generated on the file and the
87 instruments
88 - write support: improved the default values for dimension region
89 parameters
90 - more write support fixes: crossfade parameters were not saved,
91 v3 dimension limits were not correctly initialized and saved
92 when dimensions were added or deleted, v3 wave pool offsets were
93 not saved correctly
94 - write support: 24 bit samples can now be written
95 - write support: version 3 is now the default for new files
96 - more write support fixes: the 3ewg chunk is now bigger for v3,
97 dimension regions without mapped samples are now allowed, 3gnl
98 list in v3 files now always has 128 entries, several parameters
99 where incorrectly saved due to an operator precedence mistake
100 - DeleteSample now removes all references to the deleted sample
101 - AddDimension now copies all parameters from existing dimension
102 regions and also makes sure that the samplechannel dimension is
103 placed first in the list of dimensions.
104 - added method GetParent() to class 'DimensionRegion', which returns its
105 parent Region
106 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
107 unused areas
108 - added various setter methods to DimensionRegion class which take care
109 of updating lookup tables / caches.
110
111 * src/RIFF.cpp, src/RIFF.h:
112 - added File::SetByteOrder method
113 - Windows fix: saving a new file didn't work

117
118 Version 3.1.1 (24 Mar 2007)
119

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

151 causing an exception when trying to save a new instrument
152
153 * src/RIFF.cpp, src/RIFF.h:
154 - fixed RIFF::Chunk destructor which did not unregister previously
155 resized chunks, leading to a "zero size chunk" exception when
156 File::Save() was called
157 - added List::MoveSubChunk method

281 articulation informations are ignored at the moment
282 (patch by Andreas Persson)
283 - added some file format compatibility checks
284 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

334
335 * packaging changes:
336 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
337 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
338 - fixed man pages automake install rule (which didn't work on Mandrake,
339 SuSE and Fedora)
340 - fixed generation of Doxygen API documentation (now also included in
341 RPM and Debian packages)
342
343 * src/gig.cpp, src/gig.h:
344 - fixed / improved accuracy of all three velocity to volume
345 transformation functions a.k.a. 'nonlinear','linear','special'
346 (patch by Andreas Persson)
347 - denormals are filtered from the velocity to volume tables
348 - bugfix for dimension region switching (wrong handling of the release
349 trigger dimension, no bit range check for dimensions of split type

368 Version 0.7.1 (2 Jul 2004)
369
370 * packaging changes:
371 - added libgig.spec and libgig.pc package configurations for generating
372 Redhat packages
373 - header files included on installation.
374 - autotools-generated files removed from CVS repository.
375 - added support for generating Debian packages
376 - version of shared library can be set in configure.in
377
378 Version 0.7.0 (3 May 2004)
379
380 * general changes:
381 - various big endian specific corrections
382 (successfully tested now on PPC)
383 - minor adjustments to avoid compile errors on some systems
384 (using now pow() instead of powl() and --pedantic g++ compiler switch)
385 - libtoolized the library
386 - added man pages for the command line tools
387 (gigextract, gigdump, dlsdump, rifftree)
388
389 * src/gig.cpp, src/gig.h:
390 - fixed bug in decompression algorithm which caused it not to detect
391 the end of a stream
392 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
393 takes the MIDI key velocity value as an argument and returns the
394 appropriate volume factor (0.0 ... 1.0) for the sample to be played
395 back, the velocity curve transformation functions used for this are
396 only an approximation so far
397 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
398 'Sample::LoopSize' which reflected wrong values
399 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
400 measured in sample points instead of byte offset
401 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
402 'Sample::FineTune'
403 - added class attribute 'Sample::LoopSize'
404 - added method GetInstrument(uint index) to class 'File'
405 - added ReadAndLoop() method to class 'Sample' which is an extension to
406 the normal Read() method to honor the sample's looping information
407 while streaming from disk
408 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
409 'eg2_ctrl_t': replaced this huge enumeration by a structure which
410 reflects the MIDI controller number in case of an ordinary control
411 change controller (this saves a huge switch-case block in the
412 application of the library user)
413 - renamed following attributes in class 'DimensionRegion':
414 'AttenuationContol' -> 'AttenuationController',
415 'InvertAttenuationControl' -> 'InvertAttenuationController',
416 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
417 - minor fix in API documentation for method GetVelocityAttenuation() in
418 class 'DimensionRegion'
419
420 * src/RIFF.cpp, src/RIFF.h:
421 - added additional API documentation
422 - minor fix in Chunk::Read() method (only a minor efficiency issue)
423
424 * src/gigdump.cpp:
425 - added printout of samples' looping informations
426
427 Version 0.6.0 (3 Nov 2003)
428
429 * initial release
