A year after he announced the Axe Synth, a guitar-shaped optical theremin, Tony Amendolare returns with the Sonar Axe - a $425 plastic and aluminium MIDI sonar theremin thing. You trigger percussion by tapping on the red eye (or maybe the green switch), and pick notes by moving your hands up and down the neck. I think Cary would love this. Disappointingly, the old school pocket calculator doesn't seem to be part of the deal.
