Sol Programmable USB MIDI to CV

Write a review
We have run out of stock for this item. Please add it to your wishlist, and we will email you as soon as more arrive.

Sol is a uniquely customizable USB MIDI to CV/Gate module. It's designed to be useful right out of the box but flexible enough to accommodate a ton of different CV/Gate generation needs. It is an unusual module, though- Sol is the first Eurorack module that can be re-programmed using CircuitPython. It's designed from the ground up to be customized by you. You are not limited by what we’ve programmed the module to do and you don't have to become an embedded developer to impart your own magic into this module.

Manufactured in the United States.
