This is a simple passive switch modular synth module for Eurorack. Emergency push button is used as a switch component. Can be used for both ways by routing trigger signal either to A or B output or other way around by switching from trigger signal A to trigger signal B.
Wikipedia answer: Eurorack is a modular synthesizer format originally specified in 1995 by Doepfer Musikelektronik. It has since grown in popularity, and as of 2022 has become a dominant hardware modular synthesizer format, with over 15,000 modules available from more than 1000 different manufacturers ranging from DIY kits and boutique, cottage-industry designers to well-known, established synth mass-manufacturers like Moog and Roland.
Bill of Material
Requires only few parts:
- Emergency stop switch, e.g. this from Amazon.de ~13€
- 3.5mm jack socket (3 pce), e.g. this from Amazon.de ~9€/5 pce. There are cheaper sets in Aliexpress etc. ...and also mono socket would be better for Eurorack but I had these spare stereo ones available so used them.
- 3D printed panel and button
It's just a switch 🙃
Had couple of designs for the front panel. Settled on this one that tries to visualize the audio waves rushing from the button to the audio jacks.
