Software only. I've partially located the problem but am unsure of why
it occurs so frequently, again down to software.

the call to jack_midi_event_reserve returns NULL every few notes being
sequenced (instead of returning a pointer to the data where the MIDI
events should be written to). So some note-on events are missing
note-off events, and some note-off events are divorced from any
preceding note-on. Definitely s/w.

might try adjusting some JACK settings and see what happens.

Cheers,
James.
