I am running Studio One 3 Artist on a Macbook Pro Retina using OS 10.11.2. I cannot seem to get my KORG Kontrol 49 MIDI keyboard to trigger any of the virtual instruments. I have the latest driver installed and the Audio/ MIDI setup shows it listed as installed. I am also running Reason 8 and Cubase 8 on the same laptop. Both programs recognize the Kontrol 49 without anything more than selecting it in their Preferences menu. I could be doing something wrong, but after watching a half dozen tutorials on Youtube I'm not sure what that could be. Any help would be greatly appreciated as I am pretty lost at this point.
