Korg monotron DUO Analogue Ribbon Synthesizer 

The Dual Oscillator monotron DUO offers X-MOD capabilities for generating even more extreme sounds. 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.

• Two analog oscillators (VCO) with individual tunings
• Edgy X-MOD circuit borrowed from Korg’s classic Mono/Poly
• Ribbon controller keyboard with Scale Select
• Original Analog (VCF) Filter taken from the classic MS-10 & MS-20
• Aux input jack lets you apply filter to any audio source
• Built-in speaker and battery power for Go Anywhere Analog sound
• Headphone jack for private use

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.
