"Sharp 2D120X is a proximity sensor unit that can be used as it is as an analog interface. The output is a voltage that varies with the distance to any object within the optical line in front of the unit. Contrary to many other optical sensors this one doesn't work by measuring the amount of reflection. Instead it uses the triagulation principle work the angle of reflection is detected - the bigger angle the closer the reflection might be.
I made a little interface with the necessary voltage regulator (it requires 5V and my synthesizer modules runs at 9V) and a DC amplifier.
The music is played on E-mu Pro-formance/1+ piano module, Roland JX-8P synthesizer, Yamaha HE-8 organ, and Roland TR-626 drum machine."
