Touch and Go

Another drone synth, but using the CD40106 this time. Really you could make a multi drone synth out of the same chip but I've already done that with the CD4093 design previously posted. This design uses a momentary switch to make/break the power connection to the circuit. The knob controls pitch. In the end you get a pretty fun little 'instrument' that requires very little parts to make.
