Firewire Midi Control Surface, Zed R16

Does anybody know?

I’m looking at the Allen Heath Zed R16 mixing board. Claims it has support for midi control surface and was wondering if anybody here has used any firewire mixers that might have a section for midi control surfaces. In a nut shell, I know n-Track can support MIDI controls with USB devices like the Beringer BCF2000, can it support midi control as well with firewire midi supported devices?

Any help would be great.
