// This simple example assumes a MIDI device is present on port 0.
// When invoked, we route notes and other MIDI events to the
// FluidSynth plugin.  Note that this simple example supports
// chords, pitch bending, etc.  The cancel trick affords the
// opportunity to "gracefully" shutdown using x in the Fibers Control Panel
