This is probably something very simple that I'm not (obviously) seeing, but I just couldn't figure out how to use my keyboard controller to trigger Monark (usually there's a setting in the GUI to select Midi Omni, but I couldn't find it

). The only sounds that Monark made were the ones played through my qwerty keyboard. BTW, all of this is in standalone mode.......I also checked to make sure my keyboard controller (Alesis 7.1) worked fine in Kontakt 5 so it's not a controller issue.
Can someone please show me where to set this up correctly?
(sometimes my elevator just doesn't seem to be reaching the top floor.....)
