Im in the process of setting up a home recording/mixing studio, but being kind of stuck at the moment. I have been using an A&H Zed R16 for some time, but just recently bought the RME UFX interface. So question 1 is : Since both these units are functioning as firewire audio interfaces, should i sell the Zed R16 or can these interfaces be combined in a nice way and fulfill eachother ? I have a lot of stuff going on with synths, sequencer and effects etc and often play "live" and record all tracks to a daw. But i would also like to route the daw outputs back into my mixer when mixing the recorded tracks. So question 2 is : How can i set up my mixer both as a front and back end to my interface ?
