The Etherwave Plus Theremin and Controller from Moog is a musical instrument, CV, and gate controller that is played based on hand gestures and proximity to its antenna. It has 1/4" outputs for pitch and volume CV, but these can be used for any CV destination. The Etherwave Plus also has a gate output, and all three can be used to control synthesizers with corresponding inputs. Its pitch preview headphone output allows you to hear what you are playing before the audience does. The Etherwave Plus has a power LED for power status display on dark stages.
