File size: 23814 byte(s)
* gig.h/.cpp: Added new method Region::SetDimensionType().
* Bumped version (3.3.0.svn18).

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
21 * SoundFont file format:
22 - initial implementation
23 - changed region lookup API to avoid malloc in RT threads
24 - fixed GetEG1Sustain which didn't return correct value
25 - bugfix: GetPan always returned -1, 0 or 1
26
27 * KORG file format:
28 - initial support for sample based instruments in KORG's file format
29 (.KMP and .KSF files)
30
31 * AKAI file format:
32 - Added Linux/POSIX ported version of libakai. Note that libakai is released
33 under LGPL terms while libgig is released under GPL terms. To handle this
34 license difference appropriately the AKAI support part is built as
35 separate DLL (.so file).
36 - Fixed Mac OSX support so that the Akai lib files and tools compile without
37 any exotic third party libraries.
38 - Fixed various compilation errors for Windows.
39 - POSIX fix: open() requires third (mode) argument if used with O_CREAT
40 (fixes #219).

121 - bugfix: saving to the same file after the file size had been
122 increased made the file corrupt (#82)
123 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
124 is not written physically yet (#82)
125 - bugfix: saving to the same file after the file size had been
126 decreased sometimes also made the file corrupt!
127 - bugfix: undefined behavior (e.g. endless loop) when opening zero
128 length files, now throws a RIFF::Exception instead (fixes bug #121)

175 instrument constructors
176 - clear unused fields when saving samples and regions
177 - fixed write support bugs: v3 dimension limits and chunksize

192 instruments
193 - write support: improved the default values for dimension region
194 parameters
195 - more write support fixes: crossfade parameters were not saved,

197 when dimensions were added or deleted, v3 wave pool offsets were
198 not saved correctly
199 - write support: 24 bit samples can now be written

203 list in v3 files now always has 128 entries, several parameters
204 where incorrectly saved due to an operator precedence mistake
205 - DeleteSample now removes all references to the deleted sample
206 - AddDimension now copies all parameters from existing dimension
207 regions and also makes sure that the samplechannel dimension is
208 placed first in the list of dimensions.

210 parent Region
211 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
212 unused areas

232 - added support for custom splits points for other dimensions than
233 velocity (gig v3 feature)
234 - added "smart midi" and "round robin keyboard" dimensions
235 - added new method File::DeleteGroupOnly() which only deletes the given
236 group but moves all its members to another group, the other method,
237 that is File::DeleteGroup() now removes not just the group, but also
238 all the samples that belong to that group
239 - fixed crash which occured on interfering File::DeleteSample() and
240 File::GetNextSample() calls (due to iterator invalidation)

243 with the group
244 - added Instrument::MoveRegion method
245 - fixed constructor for Region, which did not initialize correctly
246 when used from Instrument::AddRegion
247 - when saving, override the gig::Regions sample reference simply by
248 the region's first dimension region's sample (avoids an exception
249 when trying to save a new instrument)

444 SuSE and Fedora)
445 - fixed generation of Doxygen API documentation (now also included in
446 RPM and Debian packages)
447
448 * src/gig.cpp, src/gig.h:
449 - fixed / improved accuracy of all three velocity to volume
450 transformation functions a.k.a. 'nonlinear','linear','special'
451 (patch by Andreas Persson)
452 - denormals are filtered from the velocity to volume tables

476 - added libgig.spec and libgig.pc package configurations for generating
477 Redhat packages
478 - header files included on installation.
479 - autotools-generated files removed from CVS repository.
480 - added support for generating Debian packages
481 - version of shared library can be set in configure.in
482
483 Version 0.7.0 (3 May 2004)
484
485 * general changes:
486 - various big endian specific corrections
487 (successfully tested now on PPC)
488 - minor adjustments to avoid compile errors on some systems
489 (using now pow() instead of powl() and --pedantic g++ compiler switch)
490 - libtoolized the library
491 - added man pages for the command line tools
492 (gigextract, gigdump, dlsdump, rifftree)
493
494 * src/gig.cpp, src/gig.h:
495 - fixed bug in decompression algorithm which caused it not to detect
496 the end of a stream
497 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
498 takes the MIDI key velocity value as an argument and returns the
499 appropriate volume factor (0.0 ... 1.0) for the sample to be played
500 back, the velocity curve transformation functions used for this are
501 only an approximation so far
502 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
503 'Sample::LoopSize' which reflected wrong values
504 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
505 measured in sample points instead of byte offset
506 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
507 'Sample::FineTune'
508 - added class attribute 'Sample::LoopSize'
509 - added method GetInstrument(uint index) to class 'File'
510 - added ReadAndLoop() method to class 'Sample' which is an extension to
511 the normal Read() method to honor the sample's looping information
512 while streaming from disk
513 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
514 'eg2_ctrl_t': replaced this huge enumeration by a structure which
515 reflects the MIDI controller number in case of an ordinary control
516 change controller (this saves a huge switch-case block in the
517 application of the library user)
518 - renamed following attributes in class 'DimensionRegion':
519 'AttenuationContol' -> 'AttenuationController',
520 'InvertAttenuationControl' -> 'InvertAttenuationController',
521 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
