Connect and control your Eurorack Synthesizer with your MIDI gear, build the Majella 4-voice expandable MIDI to CV converter! The MCVC DIY KIT is a straightforward build and creates an interface between your Eurorack synthesizer system and devices that communicate using the MIDI -protocol. The MIDI CV Converter bridges the gap between MIDI and Eurorack systems, it converts MIDI messages to control voltages, which correspond to Eurorack synthesizer signal standards. You can expand the Majella MCVC with four voices using the MCVC-exp and you can expand up to 20 voices! HERE is a building and review video by Synth DIY Guy.
