Manufacturer's ID: MONOTRON-DUO

What we say:

At A Glance:

The Monotron Duo from Korg is a powerful dual-oscillator synthesizer that fits in your pocket. Featuring a ribbon keyboard, cross-modulation and a smooth filter, the Monotron Duo is a powerful instrument.

Features We Love:

Dual Oscillator Design

The Monotron Duo features two fat sounding analogue oscillators with cross modulation. You can choose to run a single oscillator, or both together. Using the X-Mod (cross modulation) control, you can create some gnarly sounds!

Smooth Analog Filter

You will also find a lovely sounding analogue VCF filter on board the Monotron Duo. You can use this to shape the texture of the analogue oscillators, or filter an external audio source, thanks to the audio input on the unit.


The Monotron Duo is small enough to fit in your pocket, and operates on two AAA batteries. It even has a built in speaker, so you can play the instrument anywhere you go!

Korg puts the thrill of the analog synthesizer into everyone’s hands. Announcing the new monotron DUO

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. The Dual Oscillator monotron DUO offers X-MOD capabilities for generating even more extreme sounds. The monotron DELAY features a Space Delay that can produce intense, analog-like echo effects. 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.

Casual users and gadget mavens will quickly enjoy performing melodies, DJs can create dazzling effects on stage, while established players can add analog muscle to their performance – the possibilities are virtually unlimited. Grab yourself a monotron, monotron DUO, or monotron DELAY, and get in touch with the exciting world of analog synths.

Dual Oscillator / X-Mod Design
Offering two oscillators, the monotron DUO adds an extra dimension, delivering an even more extreme sound. Tune the oscillators in unison for a rich, thick, analog tone. Tune them in intervals for classic soloing sounds and generating new effects. The X-MOD (cross modulation) circuit taken from Korg's classic Mono/Poly can introduce a mild or razor-sharp edge to the overall sound; everything from a rich vibrato to extreme metallic sounds reminiscent of an FM synth.

Enhanced Ribbon Controller Keyboard
The monotron DUO's ribbon controller keyboard now features the familiar Scale function used on the KAOSSILATOR. You can use this button to select one of four scales: Chromatic, Major, Minor, or Off. Choose the Chromatic scale to play precise pitches as on a piano, or choose Major or Minor to generate musically coherent phrases by simply sliding your finger around on the keyboard.

Classic Korg Filtering
The distinctive tone of an analog filter (VCF) can dramatically alter and enrich the sound. The monotron DUO uses the same highly acclaimed VCF circuit as KORG's classic MS-10 and MS-20 semi modular synthesizers. Originally released over 30 years ago, these instruments are still coveted today for their aggressive, dynamic filters. The VCF Cutoff knob sets the frequency or tone of the filter; the VCF Peak knob adds emphasis. A powerful filter is an essential aspect of any analog synthesizer, applying dramatic tonal changes to the sound, and projecting an intense personality that will stand out in any live performance.

Fully-patchable Filter
The input jack (AUX input) built into the monotron DUO’s compact body allow you to place any audio source into the monotron DUO’s signal path, directly before the analog filter. This provides a great way to connect a KAOSSILATOR, a guitar, or a digital audio player to the monotron and enjoy tone-bending filter effects

Go Anywhere Analog
A miniature speaker is built into the monotron DUO. Along with the battery operation and compact size, this feature allows you to enjoy the share the monotron DUO’s analog synthesis sound with your friends, anywhere, at any time. There's also a headphone output that you can use when practicing in private, creating sounds at home, recording, or for connecting to an amplifier or PA system.

Overall Rating 5/5 (2 reviews)

It was bought for my brother, although he is enjoying it. I have a monotron delay which is very similar, and I rate that highly.
