The module commissioned by Projektstudio31 was built to automate the experimental organ 'Archi Organo' which uniquely features 36 tones per octave. Using 138 Solenoids, each key can be controlled through midi. The module also features two switchable 240V outputs to control the organ's air pump and a secondary external device e.g lights.
