* minor fix in configure for building DLL on Windows

1 Version CVS HEAD (?)
2
3 * general changes:
4 - fixed compilation with gcc 4.3
5 - fixes for building with Visual C++
6 - minor fix in configure for building DLL on Windows
7
8 * src/gig.cpp, src/gig.h:
9 - added partial support for MIDI rules, only the Controller
10 Triggered rule is supported so far
11 - bugfix: removed another iterator invalidation in DeleteSample
12 - bugfix in Sample::LoadSampleData*(): reset sample read position to
13 sample start before trying to (re)load sample data from file (#82)
14 - bugfix: EG3 depth parameter was not saved correctly
15 - fixed crash which occured when streaming a gig sample with
16 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
17
18 * src/RIFF.cpp, src/RIFF.h:
19 - bugfix: saving to the same file after the file size had been
20 increased made the file corrupt (#82)
21 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
22 is not written physically yet (#82)
23 - bugfix: saving to the same file after the file size had been
24 decreased sometimes also made the file corrupt!
25 - bugfix: undefined behavior (e.g. endless loop) when opening zero
26 length files, now throws a RIFF::Exception instead (fixes bug #121)
27 - bugfix: destructor for base class RIFF::Chunk accessed members
28 of derived class RIFF::File, which is bad, and caused crashes
29 when using Visual C++
30 - bugfix: files that contain zero length RIFF lists were not read
31 correctly (fixes #127) (bug was introduced 2009-03-13)
32
33 Version 3.2.1 (5 Dec 2007)
34
35 * src/RIFF.cpp, src/RIFF.h:
36 - avoid Windows to perform unnecessary file stream caching which would
37 decrease disk streaming performance on Windows systems otherwise
38
39 * src/gig.cpp, src/gig.h:
40 - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
41 applications to retrieve very superficial informations like amount of
42 instruments and their names in a very fast way
43
44 Version 3.2.0 (14 Oct 2007)
45
46 * packaging changes:
47 - added Mac OSX XCode project files (patch by Toshi Nagata)
48 - Dev-C++ (win32) project file is automatically updated with
49 the version info from configure.in

54 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
55 - fixed write support for big-endian systems
56 - improved handling of fixed length info strings - separate default
57 lengths can be specified for each INFO chunk
58 - added Resource::GenerateDLSID function
59 - write support fix: allow regions without mapped samples
60 - added method SetKeyRange() to the Region class which should be used
61 instead of setting the KeyRange member variable directly
62 - MoveRegion() method of Region class is now private
63 - added SetGain() method to Sampler class
64 - fixed crash when saving a file after a sample loop was added
65
66 * src/gig.cpp, src/gig.h:
67 - fixed segmentation fault in the gig::File destructor sequence which
68 happened when gig::Group informations were accessed before
69 - fixed write support for big-endian systems
70 - defined lengths of a fixed set of info strings. These strings
71 are saved when the file is written, even if they are empty.
72 - added missing parameter initalizations in sample, region and
73 instrument constructors
74 - clear unused fields when saving samples and regions
75 - fixed write support bugs: v3 dimension limits and chunksize
76 weren't saved, leverage controller of type controlchange
77 couldn't be saved, group name list chunk was placed wrong,
78 dimension region chunks also placed wrong
79 - added initialization of some fixed info strings in file and
80 instrument
81 - write support: files created by libgig will now have the RIFF
82 chunks in correct order
83 - write support: two previously unknown fields in dimension
84 definition are now saved
85 - added constants for gig file versions
86 - write support: the 3crc and einf chunks are now created or
87 updated when a file is saved (3crc contains sample checksums,
88 einf contains file statistics)
89 - write support: DLSID is now generated on the file and the
90 instruments
91 - write support: improved the default values for dimension region
92 parameters
93 - more write support fixes: crossfade parameters were not saved,
94 v3 dimension limits were not correctly initialized and saved
95 when dimensions were added or deleted, v3 wave pool offsets were
96 not saved correctly
97 - write support: 24 bit samples can now be written
98 - write support: version 3 is now the default for new files
99 - more write support fixes: the 3ewg chunk is now bigger for v3,
100 dimension regions without mapped samples are now allowed, 3gnl
101 list in v3 files now always has 128 entries, several parameters
102 where incorrectly saved due to an operator precedence mistake
103 - DeleteSample now removes all references to the deleted sample
104 - AddDimension now copies all parameters from existing dimension
105 regions and also makes sure that the samplechannel dimension is
106 placed first in the list of dimensions.
107 - added method GetParent() to class 'DimensionRegion', which returns its
108 parent Region
109 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
110 unused areas
111 - added various setter methods to DimensionRegion class which take care
112 of updating lookup tables / caches.
113
114 * src/RIFF.cpp, src/RIFF.h:
115 - added File::SetByteOrder method
116 - Windows fix: saving a new file didn't work

120
121 Version 3.1.1 (24 Mar 2007)
122

125 (provided Dev-C++ + mingw project file)
126 - only export relevant files to Doxygen API documentation
127
128 * src/gig.cpp, src/gig.h:
129 - custom velocity splits now works for gig v3 files too
130 - added support for custom splits points for other dimensions than
131 velocity (gig v3 feature)
132 - added "smart midi" and "round robin keyboard" dimensions
133 - added new method File::DeleteGroupOnly() which only deletes the given
134 group but moves all its members to another group, the other method,
135 that is File::DeleteGroup() now removes not just the group, but also
136 all the samples that belong to that group
137 - fixed crash which occured on interfering File::DeleteSample() and
138 File::GetNextSample() calls (due to iterator invalidation)
139 - fixed group names which were not saved
140 - fixed group destructor which did not remove the RIFF chunk associated
141 with the group
142 - added Instrument::MoveRegion method
143 - fixed constructor for Region, which did not initialize correctly
144 when used from Instrument::AddRegion
145 - when saving, override the gig::Regions sample reference simply by
146 the region's first dimension region's sample (avoids an exception
147 when trying to save a new instrument)
148 - fixed AddDimension() method which did not fill out all mandatory
149 dimension definition fields
150
151 * src/DLS.cpp, src/DLS.h:
152 - added Instrument::MoveRegion method

154 causing an exception when trying to save a new instrument
155
156 * src/RIFF.cpp, src/RIFF.h:
157 - fixed RIFF::Chunk destructor which did not unregister previously
158 resized chunks, leading to a "zero size chunk" exception when
159 File::Save() was called

284 articulation informations are ignored at the moment
285 (patch by Andreas Persson)
286 - added some file format compatibility checks
287 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

340 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
341 - fixed man pages automake install rule (which didn't work on Mandrake,
342 SuSE and Fedora)
343 - fixed generation of Doxygen API documentation (now also included in
344 RPM and Debian packages)
345
346 * src/gig.cpp, src/gig.h:
347 - fixed / improved accuracy of all three velocity to volume
348 transformation functions a.k.a. 'nonlinear','linear','special'
349 (patch by Andreas Persson)
350 - denormals are filtered from the velocity to volume tables
351 - bugfix for dimension region switching (wrong handling of the release
352 trigger dimension, no bit range check for dimensions of split type

374 - added libgig.spec and libgig.pc package configurations for generating
375 Redhat packages
376 - header files included on installation.
377 - autotools-generated files removed from CVS repository.
378 - added support for generating Debian packages
379 - version of shared library can be set in configure.in
380
381 Version 0.7.0 (3 May 2004)
382
383 * general changes:
384 - various big endian specific corrections
385 (successfully tested now on PPC)
386 - minor adjustments to avoid compile errors on some systems
387 (using now pow() instead of powl() and --pedantic g++ compiler switch)
388 - libtoolized the library
389 - added man pages for the command line tools
390 (gigextract, gigdump, dlsdump, rifftree)
391
392 * src/gig.cpp, src/gig.h:
393 - fixed bug in decompression algorithm which caused it not to detect
394 the end of a stream
395 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
396 takes the MIDI key velocity value as an argument and returns the
397 appropriate volume factor (0.0 ... 1.0) for the sample to be played
398 back, the velocity curve transformation functions used for this are
399 only an approximation so far
400 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
401 'Sample::LoopSize' which reflected wrong values
402 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
403 measured in sample points instead of byte offset
404 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
405 'Sample::FineTune'
406 - added class attribute 'Sample::LoopSize'
407 - added method GetInstrument(uint index) to class 'File'
408 - added ReadAndLoop() method to class 'Sample' which is an extension to
409 the normal Read() method to honor the sample's looping information
410 while streaming from disk
411 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
412 'eg2_ctrl_t': replaced this huge enumeration by a structure which
413 reflects the MIDI controller number in case of an ordinary control
414 change controller (this saves a huge switch-case block in the
415 application of the library user)
416 - renamed following attributes in class 'DimensionRegion':
417 'AttenuationContol' -> 'AttenuationController',
418 'InvertAttenuationControl' -> 'InvertAttenuationController',
419 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
420 - minor fix in API documentation for method GetVelocityAttenuation() in
421 class 'DimensionRegion'
422
423 * src/RIFF.cpp, src/RIFF.h:
424 - added additional API documentation
425 - minor fix in Chunk::Read() method (only a minor efficiency issue)
426
427 * src/gigdump.cpp:
428 - added printout of samples' looping informations
429
430 Version 0.6.0 (3 Nov 2003)
431
432 * initial release
