That's great, the loop of the recorded midi events seems correct.

A minor detail: I'm noticing truncated notes during an improvisation;
it makes sense if we are recording the events, but I think it's better
to avoid a forced midi noteoff at the end of the loop if the midi
track(s) is in monitor input mode ("In" button pressed, no recording),
because there aren't notes to write.
