Overview

The Korg Monotron Delay is a palm-sized analog synthesizer built around a single oscillator, a resonant low-pass filter, and an analog delay circuit inspired by Korg's legendary tape echo units. Despite its diminutive size, it delivers genuinely warm analog tones that can range from smooth bass drones to screaming, self-oscillating delay feedback. The ribbon controller provides a direct, tactile way to play pitches and sweep through sounds, while dedicated knobs for cutoff, rate, intensity, and time give real-time control over the delay and filter parameters.

A standout feature is the 1/8" auxiliary input, which routes external audio through the Monotron Delay's analog filter and delay circuit. This turns the unit into a portable effects processor for other instruments, drum machines, or even smartphone audio. Powered by just two AAA batteries with a built-in speaker, it requires zero setup to start experimenting. While it lacks MIDI, patch storage, and multi-voice capability, the Monotron Delay serves as an inspiring creative tool for sound designers, electronic musicians, and anyone curious about analog synthesis.
