Hey Mac Shack bishes. I has a question now that I'm shopping for Firewire interfaces to use with Garage Band for recording songs at home. I noticed under the Audio/MIDI setup utility, there are drop down menus to select Default Input, Default Output, and System Output. If you plug in a Firewire audio interface, like a PreSonus or Focusrite, can you change all these defaults to go to the Firewire device? I'm curious if I'll be able to play songs in iTunes into my recording monitors.
