Majella MCVC

Majella MCVC is a four-voice MIDI to CV converter that brings a modular system into the MIDI world without compromise — four independent pitch/gate/velocity outputs instead of the single, limited channel typical of cheaper converters.

Polyphony in a System That Didn't Have It

In polyphonic mode, the MCVC splits chords played on channel 1 across four modular voices using a modern note-priority algorithm, turning an inherently monophonic Eurorack system into an instrument capable of playing chords — without buying four separate converters.

Four Independent Channels When Polyphony Isn't the Goal

Alternatively, the module handles four independent MIDI channels (1-4) in mono mode, letting you drive four separate voices from different sequencer or DAW tracks, each with its own pitch, gate, and velocity. Additional clock, 2x CC, pitch bend, and modulation CV outputs round out the signal set needed for full integration with external MIDI gear.
