I have a Roland V-bass, and I am pretty impressed with it, but it has not been able to replicate the instrument sounds which I was hoping for. I am looking for the sounds on this video: http://video.google.com/videoplay?docid=3525478989944617613&q=bass The instrument modeling is superb, and I really like the quality. Since the V-bass can't do these effects, what MIDI controller is Al Caldwell using in this video to get those sounds? All help is GREATLY apprecaited edit: I'm assuming its a Roland GR-20, but honestly I have no idea. Thanks for any help!
