File length: 46624 byte(s)
Diff to previous 829 , to selected 287

File length: 46098 byte(s)
Diff to previous 799 , to selected 287

  altering portamento time, CC65 for enabling / disabling portamento
  mode, CC126 for enabling solo mode and CC127 for disabling solo mode

* Filter tuning: calculation of cutoff frequency and bandwidth
  improved. Removed use of "BasicBPFilter". Changed bandpass filter
  from constant peak to constant skirt. Use gig parameter Resonance if
  no resonance controller is set. Removed keyboard tracking influence
  on resonance.

* 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.

File length: 44740 byte(s)
Diff to previous 770 , to selected 287
* fixed event handling bug which was introduced by the recent synthesis
  optimizations (events were only processed for the first active voice)

  which can be overridden with --enable-global-attenuation

File length: 43019 byte(s)
Diff to previous 729 , to selected 287
* 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)

* 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.

* 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.

* voice stealing operates on all engine channels now

* 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)
