Do you know Vavdo controller? Its a handmade controller with 6 knobs, 5 buttons & 7 leds. Its designed more like an instrument and despite the trend of our times does not have big numbers of knobs & buttons. Its more oriented for creating custom patches in maxmsp(or pd, sc, reaktor) or for careful mapping of other ready made synths.
