Revision 840 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Sun Feb 26 13:00:08 2006 UTC (12 years, 3 months ago) by persson
File length: 13428 byte(s)
Diff to previous 832
* fixed some concurrency problems between the lscp thread and the
  audio/midi threads for these commands: load engine, set channel
  audio output device, set channel midi input device/port/channel and
  remove channel. Thanks to Vincent Bongiorno for bug reports and
  testing.
* removed an autotools warning
* fixed an iterator bug
* minor code clean-ups

Modified Sun Feb 5 10:24:05 2006 UTC (12 years, 4 months ago) by persson
File length: 13465 byte(s)
Diff to previous 831
* added smoothing of volume changes caused by control change messages
* fine tuning of the crossfade volume curve


Revision 831 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Sat Jan 28 16:55:30 2006 UTC (12 years, 4 months ago) by persson
File length: 13119 byte(s)
Diff to previous 830
* fixed global pan (CC10) which hasn't been working for a while
* fine tuning of the curves for volume (CC7) and pan (CC10 and gig
  parameter)
* added support for the "attenuation controller threshold" gig
  parameter


Revision 830 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Sun Jan 15 18:23:11 2006 UTC (12 years, 5 months ago) by persson
File length: 13175 byte(s)
Diff to previous 829
* 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 829 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Sat Jan 14 14:07:47 2006 UTC (12 years, 5 months ago) by schoenebeck
File length: 13144 byte(s)
Diff to previous 783
* implemented portamento mode and solo mode (a.k.a 'mono mode'):
  all modes can be altered via standard GM messages, that is CC5 for
  altering portamento time, CC65 for enabling / disabling portamento
  mode, CC126 for enabling solo mode and CC127 for disabling solo mode
* fixed EG3 (pitch envelope) synthesis which was neutral all the time
* configure.in: do not automatically pick optimized gcc flags if the user
  already provided some on his own (as CXXFLAGS)


Revision 783 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Sun Oct 2 14:40:52 2005 UTC (12 years, 8 months ago) by persson
File length: 13066 byte(s)
Diff to previous 770
* 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 770 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Sun Sep 11 15:56:29 2005 UTC (12 years, 9 months ago) by schoenebeck
File length: 13068 byte(s)
Diff to previous 738
* synthesis core optimizations


Revision 738 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Tue Aug 16 17:14:25 2005 UTC (12 years, 10 months ago) by schoenebeck
File length: 13084 byte(s)
Diff to previous 729
* 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 729 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Tue Jul 26 11:18:46 2005 UTC (12 years, 11 months ago) by persson
File length: 11345 byte(s)
Diff to previous 687
* improved filter cutoff calculation by adding support for the
  following gig parameters: Cutoff freq (used when no cutoff
  controller is defined), Control invert, Minimum cutoff, Velocity
  curve and Velocity range. The keyboard tracking now also scales
  cutoff frequency, not just resonance.


Revision 687 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Tue Jul 12 22:37:21 2005 UTC (12 years, 11 months ago) by schoenebeck
File length: 11217 byte(s)
Diff to previous 669
* minor efficiency fix (LFO preprocessing was performed even though the
  respective LFO was disabled by the instrument patch)


Revision 669 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Tue Jun 21 13:33:19 2005 UTC (13 years ago) by schoenebeck
File length: 10875 byte(s)
Diff to previous 663
* fixed minor issue with null/silence samples
  (those stole voices even though they don't need a voice at all which
  resulted in "voice stealing didn't work out" messages)


Revision 663 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Sat Jun 18 21:37:03 2005 UTC (13 years ago) by schoenebeck
File length: 11059 byte(s)

File length: 11043 byte(s)

  prefix and will be placed into auto generated config.h file.

Modified Mon Mar 14 22:35:44 2005 UTC (13 years, 3 months ago) by schoenebeck
File length: 11004 byte(s)
Diff to previous 411
* spawning layered voices now within a loop instead of recursively (fixes
  segmentation fault under heavy voice count load and reduces stress on the
  stack)
* voice stealing operates on all engine channels now
* limit voice stealing to MAX_AUDIO_VOICES thefts per audio fragment cycle
* fixed keygroup handling (layered voices could kill each other)


Revision 411 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Sat Feb 26 02:01:14 2005 UTC (13 years, 4 months ago) by schoenebeck
File length: 11160 byte(s)
Diff to previous 348
* design change: using now one sampler engine instance and one disk thread
  instance for all sampler channels that are connected to the same audio
  output device (and are using the same engine type of course)
* added EngineFactory / EngineChannelFactory to remove the annoying build
  dependencies e.g. of the lscpserver to the actual sampler engine
  implementations
* bumped version to 0.3.0 (current CVS state is still quite broken,
  previous, stable CVS version was tagged as "v0_2_0" and is also available
  as source tarball)

File length: 12066 byte(s)
Diff to previous 346
* another crossfade fix (honoring AttenuationController for case 0,0,0,0,
  fixed cases in_start = in_end = CrossfadeControllerValue, fixed curve for
  cases out_start < CrossfadeControllerValue < out_end, honoring
  InvertAttenuationController parameter)
* support for up to 8 dimensions as introduced by Gig V3
(patch by Andreas Persson)

* gig::Voice: fixed special crossfade case 0,0,0,0 which actually means no
  crossfade defined

Diff to previous 287
* introduced 'synthesis mode' to reduce the amount of code and conditionals
  for the current synthesis case in the main synthesis loop

  detection at runtime, only x86 so far)

File length: 17838 byte(s)
Diff to previous 285
* fixed segfault which occured whenever a voice stole a voice and was in
  turn killed in the same audio fragment, to fix that the MIDI key
  informations are now updated only after all voices were processed

File length: 17587 byte(s)
Diff to previous 245
* 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
