Hello. I am not new to the daw world, but I have been away from it for a long time. I use to have a 002 and protools, neither of which I was fond of. I was in the market to get an nice sounding stereo so I thought why not just get a daw and kill to birds with one stone. My question is, if I get a Metric Halo setup or any other outboard interface (usb or thunderbolt) can I use this and listen to all my audio through? Say I want to listen to stuff on iTunes or something, is it as simple as setting the Macbook pro audio a different channel? Thanks.
