Using Polybrute Connect. AFIK, setup is correct. Works fine until you call up an arpeggiator patch and none of them make sound. I've looked everywhere for an answer and come up empty. Any advice?

Long shot, and assuming you're using Connect as a plugin, maybe you've got your Polybrute synced to Live, and trying out presets with Live's transport stopped? This may cause Polybrute to not run its arpeggiator.
