I am running Cubase 5 and I have a Yamaha N8 digital interface/mixer. I also have an old Edirol FA-66. Maybe this isn’t possible, but what I am trying to do is utilize my FA-66 as a separate headphone device so I can have a couple of independent musician mixes. I can connect the n8 and FA-66 via Firewire. My initial thought was to have the ability to SEND Cubase tracks to the FA-66 outputs, but this is where I get hung up. It appears I can’t have multiple AISO drivers active at the same time. Anyone have any suggestions?
