Hey guys, I'm kind of a newbie as far as external control surfaces are concerned. I'm having trouble setting up my Akai MPD-18. It's linked to the usb port in my computer, all the lights are on, and I downloaded the software called "MPD18 Editor", so It's basically set up, right? But when I go into Reason (5), and go into adding control surfaces, and get it to where it says to hit any button on the surface, nothing I hit makes Reason recognize it. Any help?
