I use a Phonic mixer that has Firewire and it would work 100% but there appears to be a bug in Real Band that we are investigating. It will work up to 8 channels but when I add more it causes an error that says "Could not gave wave in header". Yet after closing the 48 (exactly 48 - the number of available tracks in RB's DAW) error boxes all the channels work. Driver support is there though I doubt they will write new drivers if there is ever the need. They don't make this particular board any longer. Later revisions are available but not this one. I would check them out because it seems you are looking for a board that has both live use (as an analog mixer) and studio use (as a control surface).

Google Phonic mixers.

Anything with a Firewire or USB connection should do. On true control surfaces like the Behringer I use, you won't have audio outs. The Phonic has mains, monitors, and effects buses.

I am using the new 1040XTRAEZ form this year. It has just 2 lines.
