Hello, I have a question.. I have an Apogee Duet Audio Interface, But I would like to have an interface where it has 2 headphone outputs with two adjustable mixes. Here's the scenario- I'm a guitarist and I'm moving over to a rack mounted digital system, If I have one of my friends come over to record duets with his line out/digital system how can I have headphones setup for him and myself, with two different mixes (meaning, he will have more of his guitar and less of mine and vice versa) Anyway, I know there has to be a way to do this, Maybe not with the Apogge Duet, But maybe with another interface? If so, Which one would you suggest, and how might I set up this "setup" with Logic and etc? Thank you for reading!
