HELP! I'm trying to expand my new Clarett 8Pre USB with an old Focusrite PLATINUM OctoPre to get a total of 16 simultaneous inputs. Is it possible? Can anyone tell me how to do this? I've been playing around with the ADAT optical ins/outs, sync button, clock, and Focusrite Control software...but, can't get it to work. Any help, suggestions, opinions, knowledge, ideas, or bro-science would be appreciated. Thank you.
