Yep, I definitely second that …!
Coincidentally I've been searching for exactly this today - more & more of my gear is being edited/controlled via iPad, so it would be totally awesome if I could also adjust my Mastermind in the same way, as I'm carrying way too much stuff to every gig & session as it is.
One additional Q related to that: is it possible to Bluetooth the Mastermind …? I did try getting a USB A-B adapter and plugging in a Bluetooth dongle, but it wouldn't work.
Thanks, Ron.
