The OTTO is an open source digital hardware synth, groovebox and FX processor. For information and documentation see our website!
We would like to invite you to our discord server where we hang out and discuss all things OTTO.
If you want to help support the development of OTTO, you can support us on Patreon. With Patreon, you can send us a small monthly amount of money, or make a one-time donation by cancelling the monthly subscription after the first payment (Note that this usually happens on the first of the month, not immediately.)
