Korg Monotron Delay

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 introduced as the latest addition to the Monotron family, which began with the original Monotron in 2010. Designed for hands-on experimentation, it features a ribbon controller for pitch input and operates on two AAA batteries, offering approximately 8 hours of use with alkaline cells. The unit includes a stereo headphone output via a 3.5 mm mini jack, making it self-contained for private play and on-the-go synthesis. It is part of a series that includes the original Monotron, Monotron Delay, and Monotron Duo.

Design

The Monotron Delay uses true-analog circuitry and includes a built-in Space Delay effect, contributing to its unique sonic character. A modification guide describes the addition of an "implant" circuit board that enables new functionality, including a second waveform option controlled by the LFO and the ability for the LFO to modulate either the filter cutoff frequency or VCO pitch, expanding its synthesis capabilities beyond the stock configuration.

Context

Market

Common issues reported include low sound volume and non-functional delay circuits, with some users identifying capacitor-related faults, such as a 10μF capacitor failure. One listing notes a current price of €55.00, suggesting ongoing availability in the secondary market.
