I just landed a battered, but working, SDS-9. I've downloaded the manual and am trying to get it to receive midi from an external source. Before I dig too deep in frustration... I'll ask you.
I know Simmons midi philosophy can be a mess, but I got my MTM's working, so I thought I had the hang of it. But this won't play from midi. Is there some general fault I might be doing? Anyone with a quick guide to setting up the midi receive channel?
