It's the first time I've used this feature of OSX, so hoped someone may have encountered this before. I'm using 2 Avid Mbox2 mini's as an aggregate device in OSX to get four outputs for a surround piece. Max will only let me select a 32khz sample rate for output? Other programs are fine with 48khz.
