Revision 1906 - (view) (download) (annotate) - [select for diffs]
Modified Sat May 16 12:14:27 2009 UTC (9 years ago) by persson
File length: 13220 byte(s)
Diff to previous 1748
* bugfix: sometimes, when playing a note twice fast, the second note
  was silent


Revision 1748 - (view) (download) (annotate) - [select for diffs]
Modified Sun Jun 22 14:46:46 2008 UTC (9 years, 11 months ago) by persson
File length: 13791 byte(s)
Diff to previous 1424
* bugfix: notes triggered at position 0 in the audio buffer were
  sometimes wrongly killed in the same buffer, causing no sound to be
  played
* fixes for audio drivers with varying buffer sizes
* Makefile fix: JACK_CFLAGS wasn't used
* JACK driver: use jack_client_open instead of the deprecated
  jack_client_new


Revision 1424 - (view) (download) (annotate) - [select for diffs]
Modified Sun Oct 14 22:00:17 2007 UTC (10 years, 7 months ago) by schoenebeck
File length: 13372 byte(s)
Diff to previous 1147
* code cleanup:
- global.h now only covers global definitions that are needed for the C++
  API header files, all implementation internal global definitions are now
  in global_private.h
- atomic.h is not exposed to the C++ API anymore (replaced the references
  in SynchronizedConfig.h for this with local definitions)
- no need to include config.h anymore for using LS's API header files
- DB instruments classes are not exposed to the C++ API
- POSIX callback functions of Thread.h are hidden
- the (optional) gig Engine benchmark compiles again
- updated Doxyfile.in
- fixed warnings in API doc generation
* preparations for release 0.5.0


Revision 1147 - (view) (download) (annotate) - [select for diffs]
Modified Tue Apr 3 17:39:52 2007 UTC (11 years, 1 month ago) by persson
File length: 13330 byte(s)
Diff to previous 1046
* fixed some more EG bugs that could cause noises or crashes


Revision 1046 - (view) (download) (annotate) - [select for diffs]
Modified Sat Feb 10 12:00:55 2007 UTC (11 years, 3 months ago) by persson
File length: 13327 byte(s)
Diff to previous 1039
* EG fine tuning: when attack is zero the EG starts at a level above
  max sustain level, which means that there is a decay phase even if
  sustain is 100%


Revision 1039 - (view) (download) (annotate) - [select for diffs]
Modified Sat Feb 3 20:46:44 2007 UTC (11 years, 3 months ago) by persson
File length: 13331 byte(s)
Diff to previous 830
* EG fix: a release value of zero could cause noises or crash
* fix of previous thread safety fix, which in some cases locked the
  engine


Revision 830 - (view) (download) (annotate) - [select for diffs]
Modified Sun Jan 15 18:23:11 2006 UTC (12 years, 4 months ago) by persson
File length: 13228 byte(s)
Diff to previous 797
* added linear interpolation of volume modulation inside a
  subfragment; this prevents clicks during voice stealing. Can be
  switched off with the --disable-interpolate-volume configure option.


Revision 797 - (view) (download) (annotate) - [select for diffs]
Modified Wed Nov 2 19:26:15 2005 UTC (12 years, 6 months ago) by persson
File length: 13207 byte(s)
Diff to previous 796
* minor EG fine tuning: attack time now has a minimum value to prevent
  clicks


Revision 796 - (view) (download) (annotate) - [select for diffs]
Modified Sun Oct 30 08:35:13 2005 UTC (12 years, 6 months ago) by persson
File length: 13092 byte(s)
Diff to previous 783
* fixed voice stealing - stolen voices weren't killed


Revision 783 - (view) (download) (annotate) - [select for diffs]
Modified Sun Oct 2 14:40:52 2005 UTC (12 years, 7 months ago) by persson
File length: 13058 byte(s)
Diff to previous 768
* EG fixes: the length of "attack hold" stage was wrong. Release stage
  can now start before attack stage ends. Cancel release didn't work
  when sustain was zero.


Revision 768 - (view) (download) (annotate) - [select for diffs]
Modified Fri Sep 2 20:11:55 2005 UTC (12 years, 8 months ago) by persson
File length: 13171 byte(s)
Diff to previous 738
* bug fixes for the new EG implementation


Revision 738 - (view) (download) (annotate) - [select for diffs]
Modified Tue Aug 16 17:14:25 2005 UTC (12 years, 9 months ago) by schoenebeck
File length: 12798 byte(s)
Diff to previous 688
* extensive synthesis optimization: reimplementation of EGs and LFO(s),
  removed synthesis parameter prerendering and the synthesis parameter
  matrix in general, splitting each audio fragment into subfragments now
  where each subfragment uses constant synthesis parameters
  (everything's still very buggy ATM)


Revision 688 - (view) (download) (annotate) - [select for diffs]
Modified Thu Jul 14 12:25:20 2005 UTC (12 years, 10 months ago) by schoenebeck
File length: 20390 byte(s)
Diff to previous 614
* if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
  then simply show a warning about possible click sounds and reduce the
  volume ramp down appropriately instead of cancelling the audio device
  connection


Revision 614 - (view) (download) (annotate) - [select for diffs]
Modified Mon Jun 6 16:54:20 2005 UTC (12 years, 11 months ago) by persson
File length: 20402 byte(s)
Diff to previous 563
* support for the gig parameters for "release velocity response"
  curves, which means the decay and release times now depends on
  velocity. The softer velocity, the longer release.
* fine tuning of the envelope curves. Decay1 and release now have two
  parts, first linear and then exponential at the end.

  description and version about this sampler
* added some API documentation comments
* minor cleanup

* All compile time options are now centrally alterable as arguments to the
  ./configure script. All options are C Macros beginning with CONFIG_
  prefix and will be placed into auto generated config.h file.

Modified Sun Feb 20 20:32:24 2005 UTC (13 years, 3 months ago) by persson
File length: 15163 byte(s)
Diff to previous 286

  (envelope went directly from attack to release)

Revision 271 - (view) (download) (annotate) - [select for diffs]
Modified Fri Oct 8 20:51:39 2004 UTC (13 years, 7 months ago) by schoenebeck
File length: 14222 byte(s)
Diff to previous 259
* libgig: fixed panorama value in DimensionRegion (invalid conversion
  from signed 7 bit to signed 8 bit)
* src/linuxsampler.cpp: stacktrace is now automatically shown on fatal
  errors (that is  segmentation faults, etc.), gdb should be installed for
  this to work
* gig::Voice: tiny accuracy fix of pan calculation
* replaced old pool classes by completely new ones which now offer
  Iterator abstraction

* implemented key groups (a.k.a exclusive groups) which is important for
  drum patches and monphonic instruments

* completely restructured source tree
* implemented multi channel support
* implemented instrument manager, which controls sharing of instruments
  between multiple sampler engines / sampler channels

  convenient implementation of further audio output driver and MIDI input
  driver for LinuxSampler
* implemented following LSCP commands: 'SET CHANNEL MIDI INPUT TYPE',
  'LOAD ENGINE', 'GET CHANNELS', 'ADD CHANNEL', 'REMOVE CHANNEL',
  'SET CHANNEL AUDIO OUTPUT TYPE'
