  • 1 monotron
  • 2 rechargeable AAA batteries (installed)
  • 1 stylus pen (optional)

How To Use

Slide the power switch from "Standby" to either the "Pitch" or "Cutoff" setting. Adjust the volume with the rotating switch located on the back of the instrument. Touch your finger or the stylus to the ribbon keyboard to sound a note. Rotate the knobs to affect the note. Check the instruction manual under Documentation for more detailed information. When finished playing the instrument move the power switch back to standby to conserve the battery.


Monotron common features:

Go Anywhere Analog
A miniature speaker is built into every monotron. Along with its compact size, this feature allows you to enjoy and share the analog synthesis sound of the monotron Series 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.

VCO + VCF = Modular synthesis building blocks
The basic analog sound-building circuit in each of the monotrons is radically simple: one voltage-controlled oscillator and one voltage-controlled filter. As a result, the process of sound creation is intuitive, and instantly understandable. And it's tons of fun. Each Korg monotron provides the joy of sonic creativity that's at the heart of analog synthesis.

Classic Korg Filtering
The distinctive tone of an analog filter (VCF) can dramatically alter and enrich the sound. The monotron Series 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 (monotron, monotron DUO) 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 each monotron’s compact body allow you to place any audio source into the 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 Series and enjoy tone-bending filter effects.

Monotron key features:

  • VCO Voltage Controlled Oscillator
  • VCF with Cutoff and Peak Control
  • LFO can be applied to the Pitch (VCO) or Filter(VCF)
  • Ribbon controller keyboard
  • 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

Versatile LFO provides audio – and visual – excitement!
The LFO (Low Frequency Oscillator) can affect either the oscillator pitch or the filter cutoff. Both the speed and the intensity are individually adjustable, so you can create anything from a gentle vibrato to swooping tone changes of galactic proportions. As you turn the LFO Rate knob – featuring an embedded LED – the speed of the modulation effect and the speed of the blinking LED will change in tandem.

Ribbon controller keyboard offers easy expression
Borrowing the enjoyment of performing with a simple touch from Korg's wildly popular KAOSS products, the monotron's ribbon controller keyboard takes this ease of use even farther. Simple finger gestures can produce expressive effects such as vibrato and glide.

Much more pleasant than similar instruments

I found this much quieter and pleasant in tones than other similar instruments offered by the library, most specifically the Pocket Piano, which was quite shrill and gave me an instant headache. This one was weird-sounding but never got to the unpleasant zone.

Limited, but fun!

Of the three monotron models, this was my favorite to play with!

You can get a lot of sounds from the small number of knobs, from very noisy to something that could carry a tune.

It's possible to play a mostly-accurate tune on the keyboard with some practice, or have fun sliding or wiggling your finger around.

It's more fun if you have on hand some miniplug patch cables (and maybe miniplug-to-1/4" adapters?), so you can plug other stuff into it. (Might be nice if the library could include something like that.)

The headphone jack has a pretty annoying hiss.
