Note the absence of an R-8. Whatever gave you that idea, Morph
I think the R-8 is one of the most excellent drummachines out there and I've mentioned it a couple of times, so maybe you remembered wrong?
Call Roland, M704. I did that with my old MC-202 and they sent me a photocopied manual really cheap. It's the easiest way.
