Hi, I can't figure out how to get my Nord Electro keyboard to appear within Presonus. I have the Nord routed via phono plug cable to a Tascam US-2x2, and the Tascam going into my computer via a USB cable. I don't want to mess with midi yet, I just want to be able to push "record" in presonus and play my nord onto a track. But I can't figure out how, and giving up for today. Any advice for a novice?
