Korg Monotron Duo Analog ribbon synthesizer with two oscillators

Go Anywhere Analog: That was the theme behind the remarkable battery-powered and palm-sized analog synthesizer that Korg dubbed the monotron. Now the powerful and fun-to-play monotron is joined by two new siblings. Each is played from a ribbon controller keyboard with newly added features. The monotron’s simple operation and ease of use (5 knobs and 1 switch) is alive and well, inviting hours of enjoyment and musical exploration.
