This was one of my main projects during the 2013 fall semester at CalArts. It’s an analog synthesizer with five square/triangle oscillators. Since it doesn’t have any envelope generators it is best used to generate drones. I also use it to make rhythmic chords by running it through an amplifier module modulated with and envelope from my Eurorack synthesizer.
Because of the nature of these analog circuits, the tuning drifts, creating natural and organic movement.
The instrument also has a switch that I call the “mad/nice” switch which purposely creates grounding issues that make the instrument sound noisy, chaotic and unpredictable.
I made this using a hex schmitt trigger IC. Each of the triggers has a capacitor and resistor (potentiometer) between their ins an outs. This creates a feedback loop that creates oscillation.
I designed the enclosure with Inkscape and I used laser cutting to print it.
