1) The real-time scheduling is not perfect, and interruptions can cause the
   output to become crackly.  IMPROVED with version 1.0.1

2) Very occasionally the MIDI input can become corrupted, causing a false
   note to be played.  FIXED with version 1.0.1

3) The filter can overload the output when the resonance is high.  This causes
   (nasty) distortion, but may be cured by reducing the (synth) volume setting.
   This is not really a bug, but is also not really a feature...
