Evan is working on upgrading his Otamatone by replacing the internal analog synthesizer with a digital synth.
Using a Teensy 3.2 paired with an audio shield, the project aims to put a digital synth in an Otamatone that will include presets that can be configured on the fly. This could be very useful in making the instrument a bit easier to play. After all, the world needs a better Otamatone.
Code for the project can be found on GitHub.
