Korg Monotron Delay

Name: Korg Monotron Delay
Brand: Korg

A battery-powered analog ribbon synthesizer with built-in Space Delay, part of Korg's compact Monotron series

Overview

The Korg Monotron Delay is a compact analog ribbon synthesizer. It was the latest addition to the Monotron family, which began with the original Monotron in 2010. Pitch comes from a ribbon controller. It runs on two AAA batteries and gets approximately 8 hours of use from alkaline cells. There is a stereo headphone output on a 3.5 mm mini jack, so the unit is self-contained for private play and for carrying around. The series includes the original Monotron, Monotron Delay, and Monotron Duo.

Design

The Monotron Delay uses true-analog circuitry and has a built-in Space Delay effect. A modification guide describes an "implant" circuit board that adds a second waveform option controlled by the LFO. It also lets the LFO modulate either the filter cutoff frequency or the VCO pitch, which goes beyond the stock configuration.

Context

Market

Common reported problems are low sound volume and delay circuits that don't work. Some users trace the faults to capacitors, such as a failed 10μF capacitor. One listing shows a current price of €55.00, so units are still turning up on the secondary market.
