Sat Aug 25 09:59:53 2007 UTC (16 years, 7 months ago) by persson
File size: 16184 byte(s)
* AddDimension now copies all parameters from existing dimension
  regions and also makes sure that the samplechannel dimension is
  placed first
* Windows fixes: compile error in DLSID generator, saving a new file
  didn't work

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
8 * src/DLS.cpp, src/DLS.h:
9 - added Sampler::AddSampleLoop() and Sampler::DeleteSampleLoop() methods
10 - fixed write support for big-endian systems
11 - improved handling of fixed length info strings - separate default
12 lengths can be specified for each INFO chunk
13 - added Resource::GenerateDLSID function
14 - write support fix: allow regions without mapped samples
15
16 * src/gig.cpp, src/gig.h:
17 - fixed segmentation fault in the gig::File destructor sequence which
18 happened when gig::Group informations were accessed before
19 - fixed write support for big-endian systems
20 - defined lengths of a fixed set of info strings. These strings
21 are saved when the file is written, even if they are empty.
22 - added missing parameter initalizations in sample, region and
23 instrument constructors
24 - clear unused fields when saving samples and regions
25 - fixed write support bugs: v3 dimension limits and chunksize
26 weren't saved, leverage controller of type controlchange
27 couldn't be saved, group name list chunk was placed wrong,
28 dimension region chunks also placed wrong
29 - added initialization of some fixed info strings in file and
30 instrument
31 - write support: files created by libgig will now have the RIFF
32 chunks in correct order
33 - write support: two previously unknown fields in dimension
34 definition are now saved
35 - added constants for gig file versions
36 - write support: the 3crc and einf chunks are now created or
37 updated when a file is saved (3crc contains sample checksums,
38 einf contains file statistics)
39 - write support: DLSID is now generated on the file and the
40 instruments
41 - write support: improved the default values for dimension region
42 parameters
43 - more write support fixes: crossfade parameters were not saved,
44 v3 dimension limits were not correctly initialized and saved
45 when dimensions were added or deleted, v3 wave pool offsets were
46 not saved correctly
47 - write support: 24 bit samples can now be written
48 - write support: version 3 is now the default for new files
49 - more write support fixes: the 3ewg chunk is now bigger for v3,
50 dimension regions without mapped samples are now allowed, 3gnl
51 list in v3 files now always has 128 entries, several parameters
52 where incorrectly saved due to an operator precedence mistake
53 - DeleteSample now removes all references to the deleted sample
54 - AddDimension now copies all parameters from existing dimension
55 regions and also makes sure that the samplechannel dimension is
56 placed first in the list of dimensions.
57
58 * src/RIFF.cpp, src/RIFF.h:
59 - added File::SetByteOrder method
60 - Windows fix: saving a new file didn't work
61
62 * src/gigdump.cpp:
63 - added some missing dimension strings
64
65 Version 3.1.1 (24 Mar 2007)
66
67 * packaging changes:
68 - ported to Windows using native Windows functions for file IO
69 (provided Dev-C++ + mingw project file)

71
72 * src/gig.cpp, src/gig.h:
73 - custom velocity splits now works for gig v3 files too
74 - added support for custom splits points for other dimensions than
75 velocity (gig v3 feature)
76 - added "smart midi" and "round robin keyboard" dimensions
77 - added new method File::DeleteGroupOnly() which only deletes the given
78 group but moves all its members to another group, the other method,
79 that is File::DeleteGroup() now removes not just the group, but also
80 all the samples that belong to that group
81 - fixed crash which occured on interfering File::DeleteSample() and
82 File::GetNextSample() calls (due to iterator invalidation)
83 - fixed group names which were not saved
84 - fixed group destructor which did not remove the RIFF chunk associated
85 with the group
86 - added Instrument::MoveRegion method
87 - fixed constructor for Region, which did not initialize correctly
88 when used from Instrument::AddRegion
89 - when saving, override the gig::Regions sample reference simply by
90 the region's first dimension region's sample (avoids an exception
91 when trying to save a new instrument)
92 - fixed AddDimension() method which did not fill out all mandatory
93 dimension definition fields
94
95 * src/DLS.cpp, src/DLS.h:
96 - added Instrument::MoveRegion method
97 - fixed software info field which was wrongly stored on instruments,
98 causing an exception when trying to save a new instrument
99
100 * src/RIFF.cpp, src/RIFF.h:
101 - fixed RIFF::Chunk destructor which did not unregister previously
102 resized chunks, leading to a "zero size chunk" exception when
103 File::Save() was called
104 - added List::MoveSubChunk method
105

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

281
282 * packaging changes:
283 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
284 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
285 - fixed man pages automake install rule (which didn't work on Mandrake,
286 SuSE and Fedora)
287 - fixed generation of Doxygen API documentation (now also included in
288 RPM and Debian packages)
289
290 * src/gig.cpp, src/gig.h:
291 - fixed / improved accuracy of all three velocity to volume
292 transformation functions a.k.a. 'nonlinear','linear','special'
293 (patch by Andreas Persson)
294 - denormals are filtered from the velocity to volume tables
295 - bugfix for dimension region switching (wrong handling of the release
296 trigger dimension, no bit range check for dimensions of split type
297 'split_type_bit')
298 - fixed panorama value in DimensionRegion (invalid conversion from
299 signed 7 bit to signed 8 bit)
300 - added class attribute 'Layers' to class 'gig::Region'
301 - symbol prototyping of gig::Region (fixes build failure with qsampler)
302
303 * src/gigextract.cpp:
304 - added support for libsndfile (if libaudiofile and libsndfile are
305 available then libsndfile is preferred)
306
307 * src/gigdump.cpp:

309 - added printout for velocity response curve parameters
310 - added printout for crossfade definitions
311 - added printout for panorama value for each DimensionRegion

313 Gigasampler layers
314
315 Version 0.7.1 (2 Jul 2004)
316
317 * packaging changes:
318 - added libgig.spec and libgig.pc package configurations for generating
319 Redhat packages
320 - header files included on installation.
321 - autotools-generated files removed from CVS repository.
322 - added support for generating Debian packages
323 - version of shared library can be set in configure.in
324
325 Version 0.7.0 (3 May 2004)
326
327 * general changes:
328 - various big endian specific corrections
329 (successfully tested now on PPC)
330 - minor adjustments to avoid compile errors on some systems
331 (using now pow() instead of powl() and --pedantic g++ compiler switch)
332 - libtoolized the library
333 - added man pages for the command line tools
334 (gigextract, gigdump, dlsdump, rifftree)
335
336 * src/gig.cpp, src/gig.h:
337 - fixed bug in decompression algorithm which caused it not to detect
338 the end of a stream
339 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
340 takes the MIDI key velocity value as an argument and returns the
341 appropriate volume factor (0.0 ... 1.0) for the sample to be played
342 back, the velocity curve transformation functions used for this are
343 only an approximation so far
344 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
345 'Sample::LoopSize' which reflected wrong values
346 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
347 measured in sample points instead of byte offset
348 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
349 'Sample::FineTune'
350 - added class attribute 'Sample::LoopSize'
351 - added method GetInstrument(uint index) to class 'File'
352 - added ReadAndLoop() method to class 'Sample' which is an extension to
353 the normal Read() method to honor the sample's looping information
354 while streaming from disk
355 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
356 'eg2_ctrl_t': replaced this huge enumeration by a structure which
357 reflects the MIDI controller number in case of an ordinary control
358 change controller (this saves a huge switch-case block in the
359 application of the library user)
360 - renamed following attributes in class 'DimensionRegion':
361 'AttenuationContol' -> 'AttenuationController',
362 'InvertAttenuationControl' -> 'InvertAttenuationController',
363 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
364 - minor fix in API documentation for method GetVelocityAttenuation() in
365 class 'DimensionRegion'
366
367 * src/RIFF.cpp, src/RIFF.h:
368 - added additional API documentation
369 - minor fix in Chunk::Read() method (only a minor efficiency issue)
370
371 * src/gigdump.cpp:
372 - added printout of samples' looping informations
373
374 Version 0.6.0 (3 Nov 2003)
375
376 * initial release
