Korg Monotron Duo Analog Ribbon Synthesiser

The Korg Monotron Duo Analog Ribbon Synthesiser is a remarkable battery-powered synthesiser that is small enough to fit in the palm of your hand but capable of producing a multitude of sounds.

Korg's Monotron Duo comes with two completely analog voltage controlled oscillators each with individual tuning functionality. The ribbon controller keyboard features scale select thus making this even more capable. In addition to this, the Monotron Duo features the original voltage controlled filter which can be found on the classic MS-10 and MS-20 models.

The Duo also comes with an AUX input jack which allows you to apply the analog VCF filter to any audio source, very useful for computer musicians.
