KORG monotron DELAY - Portable analog synthesizer with Space Delay and filter MS-20/MS-10

The Korg monotron DELAY is a pocket-sized analog synthesizer designed to create effects and textures with an unmistakable character. It combines a VCO , analog VCF inherited from the classic MS-10 / MS-20 , LFO with selectable triangular or square shape and a Space Delay that produces analog-style echoes . Its wide-range ribbon keyboard , the AUX input for processing external sources using a filter and delay, and the integrated speaker make it a creative and portable module for the studio, live or mobile sessions. It runs on 2 AAA batteries and offers an approximate battery life of 8 hours , as well as a headphone output for working in silence.

The workflow is immediate: 5 dedicated knobs (LFO Rate, LFO Intensity, VCF Cutoff, Delay Time, and Delay Feedback) and an LFO waveform switch . The Space Delay allows for everything from short, granular echoes to long repeats and self-oscillation by increasing the feedback; varying the delay time produces characteristic pitch shifts , similar to tape echoes. Thanks to the AUX input (3.5 mm mini jack), you can process drum machines, synthesizers, guitars, or other sources with the MS filter and delay, all in an ultra-compact format of 120 × 72 × 28 mm and weighing 95 g (without batteries).

Main features

• Portable analog synthesis: simple and straightforward architecture with 1 VCO, 1 VCF, 1 LFO and Space Delay .
• MS-10/MS-20 Filter: Original MS series analog VCF for aggressive sweeps and classic tones.
• Improved LFO: triangle or square shapes with rate and intensity control.
• Ribbon controller: wide-range ribbon keyboard for performance and pitch effects.
• External processing: AUX input (3.5 mm) to apply filter and delay to any source.
• Space Delay: Analog-style echoes with time and feedback control; pitch behaviors vary with time.
• True portability: built-in speaker, headphone output, 2×AAA (up to approx. 8h ), pocket size.

Product benefits

• Immediate creativity: Five controls and one switch let you sculpt sounds without menus or complex learning curve.
• Textures with character: VCF MS and Space Delay add color and musical saturation to synthesizers, drum machines, or guitars.
• Ready to go: battery-operated, with built-in speaker and headphone output for practicing or performing anywhere.
• Easy integration: AUX input and 3.5mm mini jacks for connecting to interfaces, pedals or mixers.

Frequently Asked Questions

Is the delay analog? Korg describes the effect as “analog-style echoes” ; in practice, it reproduces typical tape echo behaviors, such as pitch changes as the delay time moves.

What connectors does it use? AUX input and headphone output via 3.5mm stereo mini jack , plus an internal speaker (which is muted when headphones are connected).

Can I filter and delay an external source? Yes. Connect the source to the AUX input to process it with VCF MS and Space Delay.
