Literal:
The Thinkpad controls my Yamaha 01V96 digital mixer, and the N810 gets there through VNC.
The resolution is perfect. All 20 faders fit onscreen, no scrolling. I’ve been mixing some simple shows from a seat in the audience. Even for the hands-on and chaotic shows, being able to tweak the balcony speakers from the balcony, and set the stage mix standing next to the musicians, is simply amazing.
