Thu Jul 2 20:04:16 2015 UTC (8 years, 8 months ago) by schoenebeck
File size: 25256 byte(s)
* src/SF.cpp, src/SF.h:
- Added new method Sample::ReadNoClear().
* Added new command line tool "sf2extract" (and a man page for it).
* Bumped version (3.3.0.svn29).

1 Version CVS HEAD (?)
2 * general changes:
3 - minor Makefile fix for parallel make
4 - Mac OS X: link with CoreFoundation (for the UUID function)
5 - removed gcc 4.7 warnings
6 - modernized configure script
7 - removed usage of deprecated Automake variable INCLUDES
8 - added new command line tool "gigmerge"
9 - added "const" keyword to several methods
10 - added new command line tool "gig2mono"
11 - added man page for "sf2dump"
12 - added new command line tool "korgdump" (and a man page for it)
13 - added new command line tool "korg2gig" (and a man page for it)
14 - moved source files of command line tools to new subdir src/tools
15 - libgig.so and libakai.so files are now installed under
16 $(prefix)/lib/libgig/ by default.
17 - Header files are now installed under $(prefix)/include/libgig/ by default.
18 - Fixed various packaging issues regarding installation directories
19 (fixes #218).
20 - added new command line tool "gig2stereo" (and a man page for it)
21 - unit tests: fixed wrong return value when test suite app exits
22 (patch by Ryan Schmidt)
23 - added new command line tool "sf2extract" (and a man page for it)
24
25 * SoundFont file format:
26 - initial implementation
27 - changed region lookup API to avoid malloc in RT threads
28 - fixed GetEG1Sustain which didn't return correct value
29 - bugfix: GetPan always returned -1, 0 or 1
30
31 * KORG file format:
32 - initial support for sample based instruments in KORG's file format
33 (.KMP and .KSF files)
34
35 * AKAI file format:
36 - Added Linux/POSIX ported version of libakai. Note that libakai is released
37 under LGPL terms while libgig is released under GPL terms. To handle this
38 license difference appropriately the AKAI support part is built as
39 separate DLL (.so file).
40 - Fixed Mac OSX support so that the Akai lib files and tools compile without
41 any exotic third party libraries.
42 - Fixed various compilation errors for Windows.
43 - POSIX fix: open() requires third (mode) argument if used with O_CREAT

68 with certain velocity split sounds under certain conditions (added bound
69 constraints to prevent that)
70 - GIG FORMAT EXTENSION: added support for real-time instrument scripts.
71 - added new method Region::GetDimensionRegionIndexByValue()
72 - added new method Script::GetGroup()
73 - added new method Region::SetDimensionType()
74 - Added support for custom progress notification while saving to gig file.

76 new one being dropped after save operation and the gig file being tainted
77 (chunks at wrong location in the RIFF tree).
78 - Added new method Instrument::MoveTo() which allows to rearrange the order
79 of instruments within the same gig file.
80

87 - added inline helper methods overlaps() for struct range_t
88 - Added support for custom progress notification while saving to DLS file.
89 - Bugfix: Adding a new region in between two existing regions caused the
90 new one being dropped after save operation and the gig file being tainted
91 (chunks at wrong location in the RIFF tree).
92
93 * src/SF.cpp, src/SF.h:
94 - added new method Sample::ReadNoClear()
95
96 * src/RIFF.cpp, src/RIFF.h:
97 - bugfix: avoid calling read() with count 0 when writing a file,
98 as this may hang on some systems

109 - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
110 allows to move a subchunk within the current List, whereas the new 2nd
111 one allows to move the subchunk from the current list to another list
112 - POSIX: only assume -1 result value as error on open() calls
113 - POSIX: show operating system's error reason if opening a file failed
114 - Added support for custom progress notification while saving to RIFF file.
115 - Fixed embarrassing old bug: POSIX read() errors were never detected on

140 - fixed crash which occured when streaming a gig sample with
141 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
142
143 * src/RIFF.cpp, src/RIFF.h:
144 - bugfix: saving to the same file after the file size had been
145 increased made the file corrupt (#82)
146 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
147 is not written physically yet (#82)
148 - bugfix: saving to the same file after the file size had been

153 of derived class RIFF::File, which is bad, and caused crashes
154 when using Visual C++
155 - bugfix: files that contain zero length RIFF lists were not read
156 correctly (fixes #127) (bug was introduced 2009-03-13)

169 Version 3.2.0 (14 Oct 2007)
170
171 * packaging changes:
172 - added Mac OSX XCode project files (patch by Toshi Nagata)

198 instrument constructors
199 - clear unused fields when saving samples and regions
200 - fixed write support bugs: v3 dimension limits and chunksize

215 instruments
216 - write support: improved the default values for dimension region
217 parameters
218 - more write support fixes: crossfade parameters were not saved,
219 v3 dimension limits were not correctly initialized and saved
220 when dimensions were added or deleted, v3 wave pool offsets were
221 not saved correctly
222 - write support: 24 bit samples can now be written

226 list in v3 files now always has 128 entries, several parameters
227 where incorrectly saved due to an operator precedence mistake
228 - DeleteSample now removes all references to the deleted sample
229 - AddDimension now copies all parameters from existing dimension
230 regions and also makes sure that the samplechannel dimension is
231 placed first in the list of dimensions.

233 parent Region
234 - fixed Instrument::UpdateRegionKeyTable() method which did not reset

255 - added support for custom splits points for other dimensions than
256 velocity (gig v3 feature)
257 - added "smart midi" and "round robin keyboard" dimensions
258 - added new method File::DeleteGroupOnly() which only deletes the given
259 group but moves all its members to another group, the other method,
260 that is File::DeleteGroup() now removes not just the group, but also
261 all the samples that belong to that group
262 - fixed crash which occured on interfering File::DeleteSample() and
263 File::GetNextSample() calls (due to iterator invalidation)
264 - fixed group names which were not saved
265 - fixed group destructor which did not remove the RIFF chunk associated
266 with the group
267 - added Instrument::MoveRegion method
268 - fixed constructor for Region, which did not initialize correctly
269 when used from Instrument::AddRegion
270 - when saving, override the gig::Regions sample reference simply by
271 the region's first dimension region's sample (avoids an exception
272 when trying to save a new instrument)

274 dimension definition fields
275
276 * src/DLS.cpp, src/DLS.h:

519 the end of a stream
520 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
521 takes the MIDI key velocity value as an argument and returns the
522 appropriate volume factor (0.0 ... 1.0) for the sample to be played
523 back, the velocity curve transformation functions used for this are
524 only an approximation so far
525 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
526 'Sample::LoopSize' which reflected wrong values
527 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
528 measured in sample points instead of byte offset
529 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
530 'Sample::FineTune'
531 - added class attribute 'Sample::LoopSize'
532 - added method GetInstrument(uint index) to class 'File'
533 - added ReadAndLoop() method to class 'Sample' which is an extension to
534 the normal Read() method to honor the sample's looping information
535 while streaming from disk
536 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
537 'eg2_ctrl_t': replaced this huge enumeration by a structure which
538 reflects the MIDI controller number in case of an ordinary control
539 change controller (this saves a huge switch-case block in the
540 application of the library user)
541 - renamed following attributes in class 'DimensionRegion':
542 'AttenuationContol' -> 'AttenuationController',
543 'InvertAttenuationControl' -> 'InvertAttenuationController',
544 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
545 - minor fix in API documentation for method GetVelocityAttenuation() in
546 class 'DimensionRegion'
547
548 * src/RIFF.cpp, src/RIFF.h:
549 - added additional API documentation
550 - minor fix in Chunk::Read() method (only a minor efficiency issue)
551
552 * src/gigdump.cpp:
553 - added printout of samples' looping informations
554
555 Version 0.6.0 (3 Nov 2003)
556
557 * initial release
