8 - changed region lookup API to avoid malloc in RT threads
9 - fixed GetEG1Sustain which didn't return correct value
10
11 * src/gig.cpp:
12 - bugfix: VCF velocity dynamic range and VCF velocity curve
13 weren't saved correctly
14
15 * src/RIFF.cpp, src/RIFF.h:
16 - bugfix: avoid calling read() with count 0 when writing a file,
17 as this may hang on some systems
18 - fixed memory leak and memory handling errors when file loading
19 fails
20
21 Version 3.3.0 (30 Jul 2009)
22
23 * general changes:
24 - fixed compilation with gcc 4.3
25 - fixes for building with Visual C++
26 - minor fix in configure for building DLL on Windows
27
28 * src/gig.cpp, src/gig.h:
29 - added partial support for MIDI rules, only the Controller
30 Triggered rule is supported so far
31 - bugfix: removed another iterator invalidation in DeleteSample
32 - bugfix in Sample::LoadSampleData*(): reset sample read position to
33 sample start before trying to (re)load sample data from file (#82)
34 - bugfix: EG3 depth parameter was not saved correctly
35 - fixed crash which occured when streaming a gig sample with
36 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
37
38 * src/RIFF.cpp, src/RIFF.h:
39 - bugfix: saving to the same file after the file size had been
40 increased made the file corrupt (#82)
41 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
42 is not written physically yet (#82)
43 - bugfix: saving to the same file after the file size had been
44 decreased sometimes also made the file corrupt!
45 - bugfix: undefined behavior (e.g. endless loop) when opening zero
46 length files, now throws a RIFF::Exception instead (fixes bug #121)
47 - bugfix: destructor for base class RIFF::Chunk accessed members
48 of derived class RIFF::File, which is bad, and caused crashes
49 when using Visual C++
50 - bugfix: files that contain zero length RIFF lists were not read
51 correctly (fixes #127) (bug was introduced 2009-03-13)
52
53 Version 3.2.1 (5 Dec 2007)

61 applications to retrieve very superficial informations like amount of
62 instruments and their names in a very fast way
63
64 Version 3.2.0 (14 Oct 2007)
65
66 * packaging changes:
67 - added Mac OSX XCode project files (patch by Toshi Nagata)

92 - added missing parameter initalizations in sample, region and
93 instrument constructors
94 - clear unused fields when saving samples and regions
95 - fixed write support bugs: v3 dimension limits and chunksize
96 weren't saved, leverage controller of type controlchange
97 couldn't be saved, group name list chunk was placed wrong,
98 dimension region chunks also placed wrong
99 - added initialization of some fixed info strings in file and
100 instrument
101 - write support: files created by libgig will now have the RIFF
102 chunks in correct order
103 - write support: two previously unknown fields in dimension
104 definition are now saved

109 - write support: DLSID is now generated on the file and the
110 instruments
111 - write support: improved the default values for dimension region
112 parameters
113 - more write support fixes: crossfade parameters were not saved,
114 v3 dimension limits were not correctly initialized and saved
115 when dimensions were added or deleted, v3 wave pool offsets were
116 not saved correctly
117 - write support: 24 bit samples can now be written
118 - write support: version 3 is now the default for new files
119 - more write support fixes: the 3ewg chunk is now bigger for v3,
120 dimension regions without mapped samples are now allowed, 3gnl
121 list in v3 files now always has 128 entries, several parameters
122 where incorrectly saved due to an operator precedence mistake
123 - DeleteSample now removes all references to the deleted sample
124 - AddDimension now copies all parameters from existing dimension
125 regions and also makes sure that the samplechannel dimension is
126 placed first in the list of dimensions.
127 - added method GetParent() to class 'DimensionRegion', which returns its
128 parent Region
129 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
130 unused areas
131 - added various setter methods to DimensionRegion class which take care
132 of updating lookup tables / caches.

149 - custom velocity splits now works for gig v3 files too
150 - added support for custom splits points for other dimensions than
151 velocity (gig v3 feature)
152 - added "smart midi" and "round robin keyboard" dimensions
153 - added new method File::DeleteGroupOnly() which only deletes the given
154 group but moves all its members to another group, the other method,
155 that is File::DeleteGroup() now removes not just the group, but also
156 all the samples that belong to that group
157 - fixed crash which occured on interfering File::DeleteSample() and
158 File::GetNextSample() calls (due to iterator invalidation)
159 - fixed group names which were not saved

161 with the group
162 - added Instrument::MoveRegion method
163 - fixed constructor for Region, which did not initialize correctly
164 when used from Instrument::AddRegion
165 - when saving, override the gig::Regions sample reference simply by
166 the region's first dimension region's sample (avoids an exception
167 when trying to save a new instrument)
168 - fixed AddDimension() method which did not fill out all mandatory
169 dimension definition fields
170
171 * src/DLS.cpp, src/DLS.h:
172 - added Instrument::MoveRegion method

175
176 * src/RIFF.cpp, src/RIFF.h:

305 (patch by Andreas Persson)
306 - added some file format compatibility checks
307 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

362 SuSE and Fedora)
363 - fixed generation of Doxygen API documentation (now also included in
364 RPM and Debian packages)
365
366 * src/gig.cpp, src/gig.h:
367 - fixed / improved accuracy of all three velocity to volume
368 transformation functions a.k.a. 'nonlinear','linear','special'
369 (patch by Andreas Persson)
370 - denormals are filtered from the velocity to volume tables

400
401 Version 0.7.0 (3 May 2004)
402
403 * general changes:
404 - various big endian specific corrections
405 (successfully tested now on PPC)
406 - minor adjustments to avoid compile errors on some systems
407 (using now pow() instead of powl() and --pedantic g++ compiler switch)
408 - libtoolized the library
409 - added man pages for the command line tools
410 (gigextract, gigdump, dlsdump, rifftree)
411
412 * src/gig.cpp, src/gig.h:
413 - fixed bug in decompression algorithm which caused it not to detect
414 the end of a stream
415 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
416 takes the MIDI key velocity value as an argument and returns the
417 appropriate volume factor (0.0 ... 1.0) for the sample to be played
418 back, the velocity curve transformation functions used for this are
419 only an approximation so far
420 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
421 'Sample::LoopSize' which reflected wrong values
422 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
423 measured in sample points instead of byte offset
424 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
425 'Sample::FineTune'
426 - added class attribute 'Sample::LoopSize'
427 - added method GetInstrument(uint index) to class 'File'
428 - added ReadAndLoop() method to class 'Sample' which is an extension to
429 the normal Read() method to honor the sample's looping information
430 while streaming from disk
431 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
432 'eg2_ctrl_t': replaced this huge enumeration by a structure which
433 reflects the MIDI controller number in case of an ordinary control
434 change controller (this saves a huge switch-case block in the
435 application of the library user)
436 - renamed following attributes in class 'DimensionRegion':
437 'AttenuationContol' -> 'AttenuationController',
438 'InvertAttenuationControl' -> 'InvertAttenuationController',
439 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
440 - minor fix in API documentation for method GetVelocityAttenuation() in
441 class 'DimensionRegion'
442
443 * src/RIFF.cpp, src/RIFF.h:
444 - added additional API documentation
445 - minor fix in Chunk::Read() method (only a minor efficiency issue)
446
447 * src/gigdump.cpp:
448 - added printout of samples' looping informations
449
450 Version 0.6.0 (3 Nov 2003)
451
452 * initial release
