Tuna - Eurorack tuner module

Inspired by the original work of Amanda Ghassaei's Instructables, Sam's LookMumNoComputer Videos, and the modified code by Jos Bouten Tune-O-Matic.

This hardware is an Eurorack adapted version of the LOOKMUMNOCOMPUTER's video's on building the 1112 performance oscillators here https://www.lookmumnocomputer.com/projects#/1222-performance-vco.

The Arduino code can be found on the GitHub of Jos Bouten. https://github.com/josbouten/Tune-O-Matic
