I am using my Pro 14 (full midi mod) with two Eventide units:  Time and Modfactors.

My full midi mod GR sends program change messages only.  So the Gig Rig can change presets, or (as of the latest Eventide software update) send the factors into bypass mode.

I don't think you can program it to change banks but – since you can program it to change presets….I'm not sure why you would want to?
