So to reiterate someone’s earlier point about using din sync, the RYTM can operate in din sync mode and you should be able to wire the clock + ground onto a 3.5mm cable for sync into your sq-1. This would save a voice (or two) sending impulses. I imagine if you searched around you could find someone selling a pre-made cable.
Someone helpfully made a diagram here:
Although the advantage of using an impulse is that you can create your own rhythm with the rytm sequencer.
p.s. where in australia are you moving to? (I’m in Perth)
