From the project
Eurorack MPE implementation, 2 to 8 voices
Inspired by the use of duophony on the ARP 2600 and Odyssey, this is a MIDI to CV Eurorack module with twin outputs: low-note priority and high-note priority.
Re-utilising designs from the polyphonic Euro-MPE project, this aims to be a high-precison, flexible, and performance oriented duophonic MIDI to Eurorack CV module. It's MPE compatible, so there is independent expression on each of the two notes.
