Tuner Electronic Things... and Stuff Eurorack

A simple tuner

Tuner is a Eurorack and analog synth tuner utility.


It's a very useful tool, which should be installed in all systems: It will help you keep your VCOs in-tune with other oscillators, or with other players in your band.

It’s based on the sub-circuit proposed by LMNC in his amazing Performance VCO.

The module is equipped with 4 jack sockets, creating a passive multiple. You have the flexibility to input your oscillator’s signal into any of the 4 sockets, monitor the tuning, and subsequently route your signal to connect with other modules as needed.

The open-source firmware can be downloaded here: https://github.com/dhaillant/Tune-O-Matic
