Joy! Will it be possible to have (a mode where) the arp cycle restarts on note onset regardless of any time source? E.g. In a jam situation with no midi clock, set arpeggiator rate with the Poly sequencer speed by ear to roughly 8ths/16ths/?ths and have the cycle start afresh with each chord played (perhaps on first note-on after all notes-off). E.g. 2. Use tap tempo midi clock to achieve same thing as first example. That would be incredibly useful for ad hoc situations!
