Build a EuroPi DIY Eurorack Module

  • Synth Library Portland 1256 Lloyd Center Portland, OR, 97232 United States (map)

In this workshop participants will build and take home a EuroPi Eurorack module. The EuroPi, designed by Allen Synthesis is an open source fully user-reprogrammable Eurorack multi-function controller module based on the Raspberry Pi Pico. Use it as a master clock, CV modulator, LFO, quantizer, sequencer, arpeggiator, source of randomization and more (see below for a list of community scripts) or extend its capabilities by writing your own scripts in Python.

"The EuroPi is a project aimed at making Eurorack more accessible and customizable by giving users complete control of the inner workings of a digital module. Users can entirely reprogram the module simply by connecting it via USB to a computer, and then writing or editing the program in Python." ~ Allen Synthesis

The EuroPi module built in this workshop is a 8HP width Euro Rack module that requires a eurorack power supply to operate. No coding will be required for this class or to use the EuroPi once complete. Kits will include all required parts including a Raspberry Pi Pico2W microcontroller with wifi pre-programmed with the library of scripts listed below. Note: to optionally enable wifi users will need to program wifi settings on the Pi from a computer via the included USB cable.

Information for the EuroPi project including instructions, software, scripts, hardware schematics and a build guide can be found in the project GitHub Repository: https://github.com/Allen-Synthesis/EuroPi

DIY beginners are welcome! No prior experience is necessary. If you are brand new to DIY we can teach you the skills you need to complete the project (including how to solder) and facilitators will be there to assist with troubleshooting to help get your build working if you run into any problems. Coding questions are welcome and will be answered if possible, but this is not the focus of the workshop (scripts are provided).
