Thanks Axel!! It seems my drivers weren't installed correctly. Nano came up as a generic device. I followed this tutorial for loading the drivers properly, and then the Nano showed up by name in Reaper. Hopefully with your Keyset, I can get the sliders and pan knobs to work. For those of you who need the tutorial, go here: Thanks again Axel. You're time and consideration is one of the reasons why this forum is top notch. :) BTW, followed your instructions to a T. If I don't set device for "enable and control" instead of the control only, my tracks don't read the nano device. I'm getting a flashing green light on the track, so I assume Reaper is reading the nanokontrol, but the volume slider and pan doesn't move or change. Any idea what else I should be doing to get this thing to work?
