Sun Jun 1 00:28:46 2014 UTC (9 years, 9 months ago) by schoenebeck
File size: 23658 byte(s)
* Akai.cpp: POSIX fix: open() requires third (mode) argument
  if used with O_CREAT (fixes #219).

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.

121 is not written physically yet (#82)
122 - bugfix: saving to the same file after the file size had been
123 decreased sometimes also made the file corrupt!
124 - bugfix: undefined behavior (e.g. endless loop) when opening zero
125 length files, now throws a RIFF::Exception instead (fixes bug #121)
126 - bugfix: destructor for base class RIFF::Chunk accessed members
127 of derived class RIFF::File, which is bad, and caused crashes
128 when using Visual C++

172 instrument constructors
173 - clear unused fields when saving samples and regions
174 - fixed write support bugs: v3 dimension limits and chunksize

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

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

207 parent Region
208 - fixed Instrument::UpdateRegionKeyTable() method which did not reset

231 - added "smart midi" and "round robin keyboard" dimensions
232 - added new method File::DeleteGroupOnly() which only deletes the given
233 group but moves all its members to another group, the other method,
234 that is File::DeleteGroup() now removes not just the group, but also
235 all the samples that belong to that group
236 - fixed crash which occured on interfering File::DeleteSample() and

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

473 - added libgig.spec and libgig.pc package configurations for generating
474 Redhat packages
475 - header files included on installation.
476 - autotools-generated files removed from CVS repository.

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