Mackie Hui & Mcu

Have you already tried Duplex??

I tried to make Mackie Control layout for duplex here (the control-map is included in the latest duplex beta version already). I think your request may be fulfilled “to some degree” by using it. ;)

But please understand, current duplex doesn’t support relative encorder, so you cannot use panning knobs and jog dial.

Also, the latest duplex 0.98b18 seems to have tiny bugs (lighting update for solo & mute buttons), so please wait the next duplex release (0.98b19 or official 0.98 stable version maybe). Well, you can try using it even in the duplex 0.98b18 though.
(fixed in 0.98b19)
