By supporting MIDI output, it can be connected to digital instruments such as synthesizers, allowing you to play your favorite sounds with the theremin. However, it does not produce sound on its own, so you must have a MIDI-compatible sound source or speakers. Please be aware of this. It has hardly been used, so it is in good condition.
