* preparations for release 3.2.1

1 Version 3.2.1 (5 Dec 2007)
2
3 * src/RIFF.cpp, src/RIFF.h:
4 - avoid Windows to perform unnecessary file stream caching which would
5 decrease disk streaming performance on Windows systems otherwise
6
7 * src/gig.cpp, src/gig.h:
8 - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
9 applications to retrieve very superficial informations like amount of
10 instruments and their names in a very fast way
11
12 Version 3.2.0 (14 Oct 2007)
13
14 * packaging changes:
15 - added Mac OSX XCode project files (patch by Toshi Nagata)
16 - Dev-C++ (win32) project file is automatically updated with
17 the version info from configure.in
18 - the configure script can now be used in Windows with MSYS
19 - added a mainpage for the Doxygen API documentation
20
21 * src/DLS.cpp, src/DLS.h:
22 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
23 - fixed write support for big-endian systems
24 - improved handling of fixed length info strings - separate default
25 lengths can be specified for each INFO chunk
26 - added Resource::GenerateDLSID function
27 - write support fix: allow regions without mapped samples
28 - added method SetKeyRange() to the Region class which should be used
29 instead of setting the KeyRange member variable directly
30 - MoveRegion() method of Region class is now private
31 - added SetGain() method to Sampler class
32 - fixed crash when saving a file after a sample loop was added
33
34 * src/gig.cpp, src/gig.h:
35 - fixed segmentation fault in the gig::File destructor sequence which
36 happened when gig::Group informations were accessed before
37 - fixed write support for big-endian systems
38 - defined lengths of a fixed set of info strings. These strings
39 are saved when the file is written, even if they are empty.
40 - added missing parameter initalizations in sample, region and
41 instrument constructors
42 - clear unused fields when saving samples and regions
43 - fixed write support bugs: v3 dimension limits and chunksize
44 weren't saved, leverage controller of type controlchange
45 couldn't be saved, group name list chunk was placed wrong,
46 dimension region chunks also placed wrong
47 - added initialization of some fixed info strings in file and
48 instrument
49 - write support: files created by libgig will now have the RIFF
50 chunks in correct order
51 - write support: two previously unknown fields in dimension
52 definition are now saved
53 - added constants for gig file versions
54 - write support: the 3crc and einf chunks are now created or
55 updated when a file is saved (3crc contains sample checksums,
56 einf contains file statistics)
57 - write support: DLSID is now generated on the file and the
58 instruments
59 - write support: improved the default values for dimension region
60 parameters
61 - more write support fixes: crossfade parameters were not saved,
62 v3 dimension limits were not correctly initialized and saved
63 when dimensions were added or deleted, v3 wave pool offsets were
64 not saved correctly
65 - write support: 24 bit samples can now be written
66 - write support: version 3 is now the default for new files
67 - more write support fixes: the 3ewg chunk is now bigger for v3,
68 dimension regions without mapped samples are now allowed, 3gnl
69 list in v3 files now always has 128 entries, several parameters
70 where incorrectly saved due to an operator precedence mistake
71 - DeleteSample now removes all references to the deleted sample
72 - AddDimension now copies all parameters from existing dimension
73 regions and also makes sure that the samplechannel dimension is
74 placed first in the list of dimensions.
75 - added method GetParent() to class 'DimensionRegion', which returns its
76 parent Region
77 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
78 unused areas
79 - added various setter methods to DimensionRegion class which take care
80 of updating lookup tables / caches.
81
82 * src/RIFF.cpp, src/RIFF.h:
83 - added File::SetByteOrder method
84 - Windows fix: saving a new file didn't work

88
89 Version 3.1.1 (24 Mar 2007)
90
91 * packaging changes:
92 - ported to Windows using native Windows functions for file IO
93 (provided Dev-C++ + mingw project file)
94 - only export relevant files to Doxygen API documentation
95
96 * src/gig.cpp, src/gig.h:
97 - custom velocity splits now works for gig v3 files too
98 - added support for custom splits points for other dimensions than
99 velocity (gig v3 feature)
100 - added "smart midi" and "round robin keyboard" dimensions
101 - added new method File::DeleteGroupOnly() which only deletes the given
102 group but moves all its members to another group, the other method,
103 that is File::DeleteGroup() now removes not just the group, but also
104 all the samples that belong to that group
105 - fixed crash which occured on interfering File::DeleteSample() and
106 File::GetNextSample() calls (due to iterator invalidation)
107 - fixed group names which were not saved
108 - fixed group destructor which did not remove the RIFF chunk associated
109 with the group
110 - added Instrument::MoveRegion method
111 - fixed constructor for Region, which did not initialize correctly
112 when used from Instrument::AddRegion
113 - when saving, override the gig::Regions sample reference simply by
114 the region's first dimension region's sample (avoids an exception
115 when trying to save a new instrument)
116 - fixed AddDimension() method which did not fill out all mandatory
117 dimension definition fields
118
119 * src/DLS.cpp, src/DLS.h:
120 - added Instrument::MoveRegion method

122 causing an exception when trying to save a new instrument
123
124 * src/RIFF.cpp, src/RIFF.h:
125 - fixed RIFF::Chunk destructor which did not unregister previously
126 resized chunks, leading to a "zero size chunk" exception when
127 File::Save() was called
128 - added List::MoveSubChunk method
129

138 inside a region (for example different velocity split levels for
139 pedal up and pedal down)

253 (patch by Andreas Persson)
254 - added some file format compatibility checks
255 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

309 - fixed man pages automake install rule (which didn't work on Mandrake,
310 SuSE and Fedora)
311 - fixed generation of Doxygen API documentation (now also included in
312 RPM and Debian packages)
313
314 * src/gig.cpp, src/gig.h:
315 - fixed / improved accuracy of all three velocity to volume
316 transformation functions a.k.a. 'nonlinear','linear','special'
317 (patch by Andreas Persson)
318 - denormals are filtered from the velocity to volume tables
319 - bugfix for dimension region switching (wrong handling of the release
320 trigger dimension, no bit range check for dimensions of split type

339 Version 0.7.1 (2 Jul 2004)
340
341 * packaging changes:
342 - added libgig.spec and libgig.pc package configurations for generating
343 Redhat packages
344 - header files included on installation.
345 - autotools-generated files removed from CVS repository.
346 - added support for generating Debian packages
347 - version of shared library can be set in configure.in
348
349 Version 0.7.0 (3 May 2004)
350
351 * general changes:
352 - various big endian specific corrections
353 (successfully tested now on PPC)
354 - minor adjustments to avoid compile errors on some systems
355 (using now pow() instead of powl() and --pedantic g++ compiler switch)
356 - libtoolized the library
357 - added man pages for the command line tools
358 (gigextract, gigdump, dlsdump, rifftree)
359
360 * src/gig.cpp, src/gig.h:
361 - fixed bug in decompression algorithm which caused it not to detect
362 the end of a stream
363 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
364 takes the MIDI key velocity value as an argument and returns the
365 appropriate volume factor (0.0 ... 1.0) for the sample to be played
366 back, the velocity curve transformation functions used for this are
367 only an approximation so far
368 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
369 'Sample::LoopSize' which reflected wrong values
370 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
371 measured in sample points instead of byte offset
372 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
373 'Sample::FineTune'
374 - added class attribute 'Sample::LoopSize'
375 - added method GetInstrument(uint index) to class 'File'
376 - added ReadAndLoop() method to class 'Sample' which is an extension to
377 the normal Read() method to honor the sample's looping information
378 while streaming from disk
379 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
380 'eg2_ctrl_t': replaced this huge enumeration by a structure which
381 reflects the MIDI controller number in case of an ordinary control
382 change controller (this saves a huge switch-case block in the
383 application of the library user)
384 - renamed following attributes in class 'DimensionRegion':
385 'AttenuationContol' -> 'AttenuationController',
386 'InvertAttenuationControl' -> 'InvertAttenuationController',
387 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
388 - minor fix in API documentation for method GetVelocityAttenuation() in
389 class 'DimensionRegion'
390
391 * src/RIFF.cpp, src/RIFF.h:
392 - added additional API documentation
393 - minor fix in Chunk::Read() method (only a minor efficiency issue)
394
395 * src/gigdump.cpp:
396 - added printout of samples' looping informations
397
398 Version 0.6.0 (3 Nov 2003)
399
400 * initial release
