The Daisy Patch Submodule is a DSP platform for Eurorack synthesizer modules. It features a lightning fast STM32 processor, high fidelity stereo audio codec, and enough RAM for 10 minute long buffers - all with standard signal levels and conditioning for the Eurorack ecosystem.

Simply design your carrier board, and let the Patch Submodule do the rest!

Programming is a breeze with support for C++, Max / MSP Gen~, Pure Data, Arduino, and more. These languages can be coupled with our open source DSP library, DaisySP, for a powerful music synthesis programming environment.
