? :) That's three options, unless a PCM device already is a possible trigger for the main sequencer timer as per first option. Anyway, my favourite would be the last option. It would also allow us to implement the kind of predelay soft synths need without a big fuzz: a clock-master client would only need to advance the clock ahead of time.
