  decrease disk streaming performance on Windows systems otherwise

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

83
84 Version 3.1.1 (24 Mar 2007)
85
86 * packaging changes:
87 - ported to Windows using native Windows functions for file IO
88 (provided Dev-C++ + mingw project file)
89 - only export relevant files to Doxygen API documentation
90
91 * src/gig.cpp, src/gig.h:
92 - custom velocity splits now works for gig v3 files too
93 - added support for custom splits points for other dimensions than
94 velocity (gig v3 feature)
95 - added "smart midi" and "round robin keyboard" dimensions
96 - added new method File::DeleteGroupOnly() which only deletes the given
97 group but moves all its members to another group, the other method,
98 that is File::DeleteGroup() now removes not just the group, but also
99 all the samples that belong to that group
100 - fixed crash which occured on interfering File::DeleteSample() and
101 File::GetNextSample() calls (due to iterator invalidation)
102 - fixed group names which were not saved
103 - fixed group destructor which did not remove the RIFF chunk associated
104 with the group
105 - added Instrument::MoveRegion method
106 - fixed constructor for Region, which did not initialize correctly
107 when used from Instrument::AddRegion
108 - when saving, override the gig::Regions sample reference simply by
109 the region's first dimension region's sample (avoids an exception
110 when trying to save a new instrument)
111 - fixed AddDimension() method which did not fill out all mandatory
112 dimension definition fields
113
114 * src/DLS.cpp, src/DLS.h:
115 - added Instrument::MoveRegion method
116 - fixed software info field which was wrongly stored on instruments,
117 causing an exception when trying to save a new instrument
118
119 * src/RIFF.cpp, src/RIFF.h:
120 - fixed RIFF::Chunk destructor which did not unregister previously
121 resized chunks, leading to a "zero size chunk" exception when
122 File::Save() was called

300
301 * packaging changes:
302 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
303 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
304 - fixed man pages automake install rule (which didn't work on Mandrake,
305 SuSE and Fedora)
306 - fixed generation of Doxygen API documentation (now also included in
307 RPM and Debian packages)
308
309 * src/gig.cpp, src/gig.h:
310 - fixed / improved accuracy of all three velocity to volume
311 transformation functions a.k.a. 'nonlinear','linear','special'
312 (patch by Andreas Persson)
313 - denormals are filtered from the velocity to volume tables
314 - bugfix for dimension region switching (wrong handling of the release
315 trigger dimension, no bit range check for dimensions of split type
316 'split_type_bit')

318 signed 7 bit to signed 8 bit)
319 - added class attribute 'Layers' to class 'gig::Region'
320 - symbol prototyping of gig::Region (fixes build failure with qsampler)
321
322 * src/gigextract.cpp:

333
334 Version 0.7.1 (2 Jul 2004)
335
336 * packaging changes:
337 - added libgig.spec and libgig.pc package configurations for generating
338 Redhat packages
339 - header files included on installation.
340 - autotools-generated files removed from CVS repository.
341 - added support for generating Debian packages
342 - version of shared library can be set in configure.in
343
344 Version 0.7.0 (3 May 2004)
345
346 * general changes:
347 - various big endian specific corrections
348 (successfully tested now on PPC)
349 - minor adjustments to avoid compile errors on some systems
350 (using now pow() instead of powl() and --pedantic g++ compiler switch)
351 - libtoolized the library
352 - added man pages for the command line tools
353 (gigextract, gigdump, dlsdump, rifftree)
354
355 * src/gig.cpp, src/gig.h:
356 - fixed bug in decompression algorithm which caused it not to detect
357 the end of a stream
358 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
359 takes the MIDI key velocity value as an argument and returns the
360 appropriate volume factor (0.0 ... 1.0) for the sample to be played
361 back, the velocity curve transformation functions used for this are
362 only an approximation so far
363 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
364 'Sample::LoopSize' which reflected wrong values
365 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
366 measured in sample points instead of byte offset
367 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
368 'Sample::FineTune'
369 - added class attribute 'Sample::LoopSize'
370 - added method GetInstrument(uint index) to class 'File'
371 - added ReadAndLoop() method to class 'Sample' which is an extension to
372 the normal Read() method to honor the sample's looping information
373 while streaming from disk
374 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
375 'eg2_ctrl_t': replaced this huge enumeration by a structure which
376 reflects the MIDI controller number in case of an ordinary control
377 change controller (this saves a huge switch-case block in the
378 application of the library user)
379 - renamed following attributes in class 'DimensionRegion':
380 'AttenuationContol' -> 'AttenuationController',
381 'InvertAttenuationControl' -> 'InvertAttenuationController',
382 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
383 - minor fix in API documentation for method GetVelocityAttenuation() in
384 class 'DimensionRegion'
385
386 * src/RIFF.cpp, src/RIFF.h:
387 - added additional API documentation
388 - minor fix in Chunk::Read() method (only a minor efficiency issue)
389
390 * src/gigdump.cpp:
391 - added printout of samples' looping informations
392
393 Version 0.6.0 (3 Nov 2003)
394
395 * initial release
