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.
As hardware test boards costs money, and many of you have asked how you can contribute in a financial way, we have decided to set up a Patreon account. 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.)
