This demo of the rare Zion Turbo Guitar Synth Controller demonstrates how cool guitar synthesizers can be.

This clip shows the Zion Turbo synth guitar used with the Roland GI-20 to drive Native Instruments Reaktor 5.0 and Arturia V2600. A BX-13-VX is used to interface between the 24-pin and 13-pin interface.
