GREAT entertainer, nice voice too. One thing I don't get... regarding the "Bass keyboard" he seems to be playing multi-note chords. I would have expected it to be monophonic like bass pedals. I wonder what kind of hardware / AI module is being driven by that bass keyboard? Does it have lowest note priority? [I think MIDI Solutions sells a box that can break out the lowest note.]

Edit: Also, not sure about the ergonomics of his right-angle setup. (Not what the piano teacher taught me, but hey, can you argue with success?) Why not just use an 88-key performance synth, split the keyboard and use MIDI out??
