A page dedicated to Lunetta Synthesis, the art of repurposing and perverting digital logic semiconductor chips into sound-producing devices. The techniques of Lunetta Synthesis were pioneered by sculptor and percussionist Stanley Lunetta in the 1970's. In 2014, Noisebridge was honored to host a talk and demonstration by Stanley Lunetta himself. Stanley3.jpgStanley2.jpg

This page is a work-in-progress. Feel free to add more info and links, but please try to keep it organized.

General Tips

For visual fun, use LED's wherever a schematic calls for diodes.

Lunetta Oscillator

The Lunetta Oscillator is the heart of Lunetta Synthesis. It's an oscillator based on a Schmitt Inverter.

Driving one Schmitt oscillator with another, through a diode, and using a switch as a trigger:

CD40106 Hex Schmitt architecture:


Most Lunetta syntesizers out there are raucous and chaotic. But sweet, gentle sounds are also possible.

  • Tap the inverter output to obtain a loud, buzzy, digital square wave.
  • Tap the inverter input to obtain a gentle, soft, analog triangular wave. That's the voltage presented by the capacitor as it charges/discharges.
