Sorry Dude...but you gotta do your own legwork on that! There are things that require experience to be able to share and then there are things that one just has to do for themselves....like wiping your nose, washing your hands, etc..

Why do you need 24 inputs if all you are going to do is use it as a control surface?

The Yamaha 01V96 will act as a control surface for Cubase. Used as a mixer, it has 32 mono channels selectable from 42 inputs.
