In reading through your comments here is seems you guys aren't understanding the purpose of the Studio Mix (which by the way, I STILL wouldn't buy). I may be misunderstanding myself, but it is NOT a Mixer in the Mackie mixer sense. And it is NOT a sound card. It is nothing more than a controller for Cakwalk. You slide the volume knob, and the track volume in cakewalk gets louder or softer. You turn the pan, and it changes the panning IN CAKEWALK.
It may have a L/R out so you can send out a "final mix" I don't know, but it's a controller, not a mixer. It's for people who want to use cakewalk with the "Real Feel" of a mixer.
