CMC fader controller with Mac Mainstage?

Hi folks,
anyone know whether the gorgeous looking cmc fader controller is going to work in my system? Doepfer PK88 keyboard into new Macbook pro running Yosemite 10.10.2 via Focusrite Pro14 interface. Don’t need it to do anything fancy, just move volume faders in Mainstage. Any response gratefully received.
