No, there isn't. I'm not up on dinsync, so don't know if you can advance the sequencer step-by-step using it like is possible using gate signals. Perhaps some way of sending stop/continue signals maybe
Dunno...
I tend to use the BSP drum sequencer as my master drum controller and then slave my other machines to it either via a gate out or midi, so haven't thought about triggering it with another machine.
Slightly OT, is the dinsync working properly yet? Last I tried it was running out of sync with midi.
