I'm very used to my instrument and I feel proud about the fact that many others in my town, with terrific keyboards, can't do what I can in my modest i4S. I've heard sequences made in Ensoniqs, Korg i-30s, X3, 01-W and they show the total absence of research and curiosity from their owners. They say: "This is a limited instrument. It can't do this or this". I reply: "Instrument's aren't limited. We are." I play both electric and upright. I have a Carvin BB75 bass guitar (5-string), an acoustic upright which I play with German bow and an electric upright made in Colombia (the one that I'm playing in the picture I sent to you). Also have a Zoom BFX-708 bass effects processor.
