Korg Monotron DUO Analogue Synthesizer Dual Filter AUX

Space Delay and AUX input.

Original analogue filter circuit from Korg's MS-10/MS-20 synthesizers.

Integrated speaker, and able to run on battery power.

Go Anywhere Analogue: That was the idea behind the development of the palm-sized, battery-powered analogue Monotron synthesizer. The Korg Monotron DUO is another synthesizer from the Monotron-family, and is fun and addictive. It has, as the name implies, two oscillators with cross-modulation ability which can create extraordinary sounds. What remains is the ease of use that you may have already experienced with the Monotron series. It is often said that less is more. The Monotron DUO proves this: five buttons and a switch is all you need to go on a long, musically-inspiring journey of discovery.

Whether a beginner or a seasoned pro - everyone will soon have fun creating sounds and melodies. DJs can embed live effects, while established musicians can add some analogue muscle to their performance - the possibilities are endless. In short: by getting a Monotron, you get in touch with the amazing world of the Korg analogue synths.

With the presence of two oscillators, the Monotron DUO adds a new dimension, bringing new and unusual sounds. The ribbon controller keyboard features the familiar Scale function used on the KAOSSILATOR. One button can be used to select from one of the four existing scale settings: Chromatic, Major, Minor, or Off. The distinctive sound of an analogue filter (VCF) can completely change the sound and also bring more depth. The Monotron DUO uses the same VCF circuit that helped KORG's classic MS-10 and MS-20 semi-modular synthesizers to find fame.

After more than 30 years, these instruments are still popular thanks to their dynamic and aggressive filters.

The AUX input allows for external audio sources to be connected directly into the signal path before the analogue filter. Connect a KAOSSILATOR, guitar or your MP3 player with the Monotron DUO and bend the sound to your heart's content!

Thanks to its compact size, built-in speaker and battery power, it is possible to use the Monotron DUO anywhere. With the integrated headphone output you can create sounds and ideas at home, practise in private, record, or connect to an amplifier or PA system.
