Bastl Instruments 1983 in excellent condition — a 4-channel polyphonic MIDI to CV interface with one of the most thoughtful feature sets in its class. Four channels of CV and gate configurable across multiple layouts: up to 4-voice polyphony, mono splits, velocity, CC, aftertouch, clock, and reset outputs. Automatic tuning via the TUNE button maps each oscillator's response across seven octaves with a single press. CV inputs for transpose, portamento, window, and update. Also functions as a quad quantizer. Smoke-free studio. Original box and power cable included.
