Ok. I am looking to get a small MIDI controller to put down keyboard parts with, and misc. parts that I thinks would be better (strings for example, I can't recreate with guitar tunings, ebows, or effects, well, I could, but they wouldn't sound close to the tone I want, or maybe they would...) Anyway, would I be able to just buy a MIDI controller and run it straight to N-track? Or would I need to install software? Should I just get a yamaha keyboard?
