Lippold Haken, inventor of the Continuum Fingerboard, has worked over 20 years on this amazing controller. On the surface it is a strip of cloth sheet that feels "gushy" to the touch. But when you place your fingers on it sound comes out (assuming you have it connected up to some kind of synth).

In this video Mark Smart, a master of this controller, shows us the type of tactile control that is possible on this instrument. With the help of Haken Audio's new Continuum Control Voltage Converter, Mark plays his modified Arp Axe like we've never seen one played.

You can order a custom model from the Haken Audio website, just like Jordan Rudess from Dream Theater. That'll cost you a pretty penny though. A half sized model can be purchased for under $4000 dollars (still a pretty penny but, c'mon, this thing is really cool).
