Cubase 7.5, Muse Receptor and ADAT


I wonder if anyone out there can guide me through how to set up Cubase to recive ADAT from a Muse Receptor. I have two Receptors, A Focusrite saffire pro40 and A Yamaha 01V96 with 2 X ADAT in/out.
When I make music in Cubase I make several MIDI-tracks. To get seperate audiotracks I have to record each MIDI-track through the Focusrite… I know that this is not a good way of working!!

So, I hope that someone can give me a recipe how to set up my software and hardware.
