Overview

The Allen Synthesis EuroPi is a fully reprogrammable Eurorack module built around a Raspberry Pi Pico. You connect it to a computer over USB and write or edit its behaviour in MicroPython, and it turns that code into modular-level signals. It suits Eurorack users who want to build their own modulation, sequencing or utility tools, especially those who are comfortable writing code or building DIY hardware.

  • Six CV outputs at 0–10V, each with its own indicator LED
  • Hands-on control from two 12-bit knobs and two push buttons
  • One CV input (0–12V, 12-bit) plus a digital input for an external clock or gate
  • 128×32 OLED display for script feedback and parameters
  • I²C expansion header on the back for adding sensors or extra outputs

The whole project is open source. The software is under Apache 2.0, the hardware under CERN OHL-S v2 and the documentation under CC0 1.0, and the hardware is certified by the Open Source Hardware Association. Firmware, an API documentation site, the build guide and a growing collection of user-contributed scripts are all on the project's GitHub. The module is set up and calibrated before any software is loaded. Users can get help and share ideas in the r/EuroPi Reddit community and on the project's Discord server.
