* the configure script can now be used in Windows with MSYS

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - added Mac OSX XCode project files (patch by Toshi Nagata)
5 - Dev-C++ (win32) project file is automatically updated with
6 the version info from configure.in
7 - the configure script can now be used in Windows with MSYS
8
9 * src/DLS.cpp, src/DLS.h:
10 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
11 - fixed write support for big-endian systems
12 - improved handling of fixed length info strings - separate default
13 lengths can be specified for each INFO chunk
14 - added Resource::GenerateDLSID function
15 - write support fix: allow regions without mapped samples
16
17 * src/gig.cpp, src/gig.h:
18 - fixed segmentation fault in the gig::File destructor sequence which
19 happened when gig::Group informations were accessed before
20 - fixed write support for big-endian systems
21 - defined lengths of a fixed set of info strings. These strings
22 are saved when the file is written, even if they are empty.
23 - added missing parameter initalizations in sample, region and
24 instrument constructors
25 - clear unused fields when saving samples and regions
26 - fixed write support bugs: v3 dimension limits and chunksize
27 weren't saved, leverage controller of type controlchange
28 couldn't be saved, group name list chunk was placed wrong,
29 dimension region chunks also placed wrong
30 - added initialization of some fixed info strings in file and
31 instrument
32 - write support: files created by libgig will now have the RIFF
33 chunks in correct order
34 - write support: two previously unknown fields in dimension
35 definition are now saved
36 - added constants for gig file versions
37 - write support: the 3crc and einf chunks are now created or
38 updated when a file is saved (3crc contains sample checksums,
39 einf contains file statistics)
40 - write support: DLSID is now generated on the file and the
41 instruments
42 - write support: improved the default values for dimension region
43 parameters
44 - more write support fixes: crossfade parameters were not saved,
45 v3 dimension limits were not correctly initialized and saved
46 when dimensions were added or deleted, v3 wave pool offsets were
47 not saved correctly
48 - write support: 24 bit samples can now be written
49 - write support: version 3 is now the default for new files
50 - more write support fixes: the 3ewg chunk is now bigger for v3,
51 dimension regions without mapped samples are now allowed, 3gnl
52 list in v3 files now always has 128 entries, several parameters
53 where incorrectly saved due to an operator precedence mistake
54 - DeleteSample now removes all references to the deleted sample
55 - AddDimension now copies all parameters from existing dimension
56 regions and also makes sure that the samplechannel dimension is
57 placed first in the list of dimensions.
58 - added method GetParent() to class 'DimensionRegion', which returns its
59 parent Region
60
61 * src/RIFF.cpp, src/RIFF.h:
62 - added File::SetByteOrder method
63 - Windows fix: saving a new file didn't work
64
65 * src/gigdump.cpp:
66 - added some missing dimension strings
67
68 Version 3.1.1 (24 Mar 2007)
69
70 * packaging changes:
71 - ported to Windows using native Windows functions for file IO
72 (provided Dev-C++ + mingw project file)
73 - only export relevant files to Doxygen API documentation
74
75 * src/gig.cpp, src/gig.h:
76 - custom velocity splits now works for gig v3 files too
77 - added support for custom splits points for other dimensions than
78 velocity (gig v3 feature)
79 - added "smart midi" and "round robin keyboard" dimensions
80 - added new method File::DeleteGroupOnly() which only deletes the given
81 group but moves all its members to another group, the other method,
82 that is File::DeleteGroup() now removes not just the group, but also
83 all the samples that belong to that group
84 - fixed crash which occured on interfering File::DeleteSample() and
85 File::GetNextSample() calls (due to iterator invalidation)
86 - fixed group names which were not saved
87 - fixed group destructor which did not remove the RIFF chunk associated
88 with the group
89 - added Instrument::MoveRegion method
90 - fixed constructor for Region, which did not initialize correctly
91 when used from Instrument::AddRegion
92 - when saving, override the gig::Regions sample reference simply by
93 the region's first dimension region's sample (avoids an exception
94 when trying to save a new instrument)
95 - fixed AddDimension() method which did not fill out all mandatory
96 dimension definition fields
97
98 * src/DLS.cpp, src/DLS.h:
99 - added Instrument::MoveRegion method
100 - fixed software info field which was wrongly stored on instruments,
101 causing an exception when trying to save a new instrument
102
103 * src/RIFF.cpp, src/RIFF.h:
104 - fixed RIFF::Chunk destructor which did not unregister previously
105 resized chunks, leading to a "zero size chunk" exception when
106 File::Save() was called
107 - added List::MoveSubChunk method
108

120 instead of the wave chunk
121 - keyswitching dimension is changed from split type "normal" to

231 articulation informations are ignored at the moment
232 (patch by Andreas Persson)
233 - added some file format compatibility checks
234 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

284
285 * packaging changes:
286 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

288 - fixed man pages automake install rule (which didn't work on Mandrake,
289 SuSE and Fedora)
290 - fixed generation of Doxygen API documentation (now also included in
291 RPM and Debian packages)
292
293 * src/gig.cpp, src/gig.h:
294 - fixed / improved accuracy of all three velocity to volume
295 transformation functions a.k.a. 'nonlinear','linear','special'
296 (patch by Andreas Persson)
297 - denormals are filtered from the velocity to volume tables
298 - bugfix for dimension region switching (wrong handling of the release
299 trigger dimension, no bit range check for dimensions of split type

304 - symbol prototyping of gig::Region (fixes build failure with qsampler)
305

318 Version 0.7.1 (2 Jul 2004)
319
320 * packaging changes:
321 - added libgig.spec and libgig.pc package configurations for generating
322 Redhat packages
323 - header files included on installation.
324 - autotools-generated files removed from CVS repository.
325 - added support for generating Debian packages
326 - version of shared library can be set in configure.in
327
328 Version 0.7.0 (3 May 2004)
329
330 * general changes:
331 - various big endian specific corrections
332 (successfully tested now on PPC)
333 - minor adjustments to avoid compile errors on some systems
334 (using now pow() instead of powl() and --pedantic g++ compiler switch)
335 - libtoolized the library
336 - added man pages for the command line tools
337 (gigextract, gigdump, dlsdump, rifftree)
338
339 * src/gig.cpp, src/gig.h:
340 - fixed bug in decompression algorithm which caused it not to detect
341 the end of a stream
342 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
343 takes the MIDI key velocity value as an argument and returns the
344 appropriate volume factor (0.0 ... 1.0) for the sample to be played
345 back, the velocity curve transformation functions used for this are
346 only an approximation so far
347 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
348 'Sample::LoopSize' which reflected wrong values
349 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
350 measured in sample points instead of byte offset
351 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
352 'Sample::FineTune'
353 - added class attribute 'Sample::LoopSize'
354 - added method GetInstrument(uint index) to class 'File'
355 - added ReadAndLoop() method to class 'Sample' which is an extension to
356 the normal Read() method to honor the sample's looping information
357 while streaming from disk
358 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
359 'eg2_ctrl_t': replaced this huge enumeration by a structure which
360 reflects the MIDI controller number in case of an ordinary control
361 change controller (this saves a huge switch-case block in the
362 application of the library user)
363 - renamed following attributes in class 'DimensionRegion':
364 'AttenuationContol' -> 'AttenuationController',
365 'InvertAttenuationControl' -> 'InvertAttenuationController',
366 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
367 - minor fix in API documentation for method GetVelocityAttenuation() in
368 class 'DimensionRegion'
369
370 * src/RIFF.cpp, src/RIFF.h:
371 - added additional API documentation
372 - minor fix in Chunk::Read() method (only a minor efficiency issue)
373
374 * src/gigdump.cpp:
375 - added printout of samples' looping informations
376
377 Version 0.6.0 (3 Nov 2003)
378
379 * initial release
