The Supercritical Demon Core Expander module introduces polyphonic control of the DCO. The stacks can be divided between up to 16 polyphonic voices, via MIDI or four 1V/oct inputs with attenuator. The oscillator can be set in continuous streaming mode or in MIDI gating mode with an ADSR envelope for each polyphonic voice. The time sync can be also triggered via MIDI for each voice and the phase sync time can be adjusted from past to future. The expander provides a handy MIDI interface and some extra CV controls.
