De careful with Behringer. The cheap control surfaces are NOT touch sensitive and will NOT track automation curves properly. I bought a secondhand Tascam FW 1884 and only use the control surface part and its perfect. All the basic functions work (Faders, Pan, Mute and Solo). None of the Mackie protocol interfaces can properly handle ProChannel. I had the Behringer and sent it back. You can get the tascam for around 300. Also, IF you want another interface, you can use that too but I bypass the interface and use only yhr control surface. I use Focusrite interface. With the cheaper Behringer, if you are trying to write an automation curve, only tracks the actual movement and then sets back to zero rather than stay at the point you moved to. If you are looking for FULL X3 support, I do not think there is anything out there that supports it except MAYBE the discontinued VS 700
