  saved correctly

1 Version CVS HEAD (?)
2 * general changes:
3 - minor Makefile fix for parallel make
4
5 * SoundFont file format
6 - initial implementation
7 - changed region lookup API to avoid malloc in RT threads
8
9 * src/gig.cpp:
10 - bugfix: VCF velocity dynamic range and VCF velocity curve
11 weren't saved correctly
12
13 * src/RIFF.cpp, src/RIFF.h:
14 - bugfix: avoid calling read() with count 0 when writing a file,
15 as this may hang on some systems
16
17 Version 3.3.0 (30 Jul 2009)
18
19 * general changes:
20 - fixed compilation with gcc 4.3
21 - fixes for building with Visual C++
22 - minor fix in configure for building DLL on Windows
23
24 * src/gig.cpp, src/gig.h:
25 - added partial support for MIDI rules, only the Controller
26 Triggered rule is supported so far
27 - bugfix: removed another iterator invalidation in DeleteSample
28 - bugfix in Sample::LoadSampleData*(): reset sample read position to
29 sample start before trying to (re)load sample data from file (#82)
30 - bugfix: EG3 depth parameter was not saved correctly
31 - fixed crash which occured when streaming a gig sample with
32 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
33
34 * src/RIFF.cpp, src/RIFF.h:
35 - bugfix: saving to the same file after the file size had been
36 increased made the file corrupt (#82)
37 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
38 is not written physically yet (#82)
39 - bugfix: saving to the same file after the file size had been
40 decreased sometimes also made the file corrupt!
41 - bugfix: undefined behavior (e.g. endless loop) when opening zero
42 length files, now throws a RIFF::Exception instead (fixes bug #121)
43 - bugfix: destructor for base class RIFF::Chunk accessed members
44 of derived class RIFF::File, which is bad, and caused crashes
45 when using Visual C++
46 - bugfix: files that contain zero length RIFF lists were not read
47 correctly (fixes #127) (bug was introduced 2009-03-13)
48
49 Version 3.2.1 (5 Dec 2007)
50

56 - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
57 applications to retrieve very superficial informations like amount of
58 instruments and their names in a very fast way
59
60 Version 3.2.0 (14 Oct 2007)
61
62 * packaging changes:
63 - added Mac OSX XCode project files (patch by Toshi Nagata)

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

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

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

157 with the group
158 - added Instrument::MoveRegion method
159 - fixed constructor for Region, which did not initialize correctly
160 when used from Instrument::AddRegion
161 - when saving, override the gig::Regions sample reference simply by
162 the region's first dimension region's sample (avoids an exception
163 when trying to save a new instrument)

165 dimension definition fields
166
167 * src/DLS.cpp, src/DLS.h:

300 articulation informations are ignored at the moment
301 (patch by Andreas Persson)
302 - added some file format compatibility checks
303 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

353
354 * packaging changes:
355 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

358 SuSE and Fedora)
359 - fixed generation of Doxygen API documentation (now also included in
360 RPM and Debian packages)
361
362 * src/gig.cpp, src/gig.h:
363 - fixed / improved accuracy of all three velocity to volume
364 transformation functions a.k.a. 'nonlinear','linear','special'
365 (patch by Andreas Persson)
366 - denormals are filtered from the velocity to volume tables
367 - bugfix for dimension region switching (wrong handling of the release
368 trigger dimension, no bit range check for dimensions of split type

391 Redhat packages
392 - header files included on installation.
393 - autotools-generated files removed from CVS repository.
394 - added support for generating Debian packages
395 - version of shared library can be set in configure.in
396
397 Version 0.7.0 (3 May 2004)
398
399 * general changes:
400 - various big endian specific corrections
401 (successfully tested now on PPC)
402 - minor adjustments to avoid compile errors on some systems
403 (using now pow() instead of powl() and --pedantic g++ compiler switch)
404 - libtoolized the library
405 - added man pages for the command line tools
406 (gigextract, gigdump, dlsdump, rifftree)
407
408 * src/gig.cpp, src/gig.h:
409 - fixed bug in decompression algorithm which caused it not to detect
410 the end of a stream
411 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
412 takes the MIDI key velocity value as an argument and returns the
413 appropriate volume factor (0.0 ... 1.0) for the sample to be played
414 back, the velocity curve transformation functions used for this are
415 only an approximation so far
416 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
417 'Sample::LoopSize' which reflected wrong values
418 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
419 measured in sample points instead of byte offset
420 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
421 'Sample::FineTune'
422 - added class attribute 'Sample::LoopSize'
423 - added method GetInstrument(uint index) to class 'File'
424 - added ReadAndLoop() method to class 'Sample' which is an extension to
425 the normal Read() method to honor the sample's looping information
426 while streaming from disk
427 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
428 'eg2_ctrl_t': replaced this huge enumeration by a structure which
429 reflects the MIDI controller number in case of an ordinary control
430 change controller (this saves a huge switch-case block in the
431 application of the library user)
432 - renamed following attributes in class 'DimensionRegion':
433 'AttenuationContol' -> 'AttenuationController',
434 'InvertAttenuationControl' -> 'InvertAttenuationController',
435 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
436 - minor fix in API documentation for method GetVelocityAttenuation() in
437 class 'DimensionRegion'
438
439 * src/RIFF.cpp, src/RIFF.h:
440 - added additional API documentation
441 - minor fix in Chunk::Read() method (only a minor efficiency issue)
442
443 * src/gigdump.cpp:
444 - added printout of samples' looping informations
445
446 Version 0.6.0 (3 Nov 2003)
447
448 * initial release
