I have an aggregate device set up in OSX with my rosetta, and the apple built in output and Audio/Midi setup reports no clock issues between the two. I'm using the Aggaragate device as my audio interface in L9. What I need to do is have the clock out on the built in output so I can use all rosetta I/O with metronome sounding on a diferent mixer channel. PROBLEM IS; under project settings, the metronome will only use outputs 1-8 anyone have any experience in this area? Does L9 even allow full use of an aggregate device? Thanks!
