Korg monotron DUO

Two tiny oscillators, a surprisingly unruly pocket.

The monotron DUO is a palm-sized synthesizer played on a touch ribbon instead of piano keys. Slide a finger, turn the knobs and make its two sound generators argue with each other. A small built-in speaker lets the experiments escape into the room.

WHY IT CAUGHT OUR EYE

It makes sound design physical: five knobs and a ribbon invite you to try something before you know what it is called.

BEFORE YOU BUY

This is the DUO version, not the DELAY or original monotron. Its ribbon takes practice for precise notes. Check the seller's case and battery contents; headphones and other instruments are not shown as included.

One monotron DUO (MONOTRONDUO), the dual-oscillator version. The Amazon entry lists a case, which is not pictured. Not the original monotron or monotron DELAY.
