I'm quite keen to see (in addition to realtime MIDI handling and saving) the
opportunity to run the non-continuous MIDI events from a MIDI sequence
(maybe after conversion to a score) in non-realtime so that I can work with
standard score pfields: ie. so that the note durations are already known to
the instrument, so to speak.

ie.
channel number may be assigned to the p1
note on - p2, note off p3
everything else definable eg. velocity to p4 etc.

This may seem like some sort of step backwards but it would be useful if you
want to get absolute control over pvoc timepoints etc. over the p3 duration.
