Voyager Touch Pad

Question for those who’ve already acquired the rackmountable Mm Voyager. Yes, it’s got everything from the keyboard version, except the illuminated wheels and touchpad controller. But, does that pad exist on another controller device? I’ve seen one similar to it on the Roland V-Synth. Does it function the same way?

. . . anyone? . . .

Uh-oh! Sorry. No-one’s tried it yet. Same question above, once the Voyager Rack has started shipping.
