Korg MS20 mini Monophonic Analogue Synthesiser

The Korg MS-20 mini is a faithful, component-by-component recreation of the legendary 1978 monophonic analog synthesizer, scaled down to 86% of its original size. Overseen by the original development engineers, it retains the exact same analog circuitry, dual oscillators, and aggressive self-oscillating filters that defined the original sound. Modernized with MIDI and USB connectivity, it offers the ultimate semi-modular experience for classic growling basses, piercing leads, and experimental sound design.
Key Features
• Authentic Analog Circuitry: Recreates the classic 2VCO / 2VCA / 2VCF / 2EG / 1LFO structure of the original 1978 MS-20.
• Iconic Self-Oscillating Filters: Features both first-generation High-Pass and Low-Pass filters with distinctive peak distortion.
• Flexible Patching Bay: Semi-modular architecture allows players to completely reroute the signal path using standard 1/8′ (3.5 mm) patch cables.
• External Signal Processor (ESP): Uses the pitch or volume of an external audio source (e.g., guitar or mic) to control the synthesizer.
• Modern Integration: Added 5-pin MIDI Input and USB-MIDI port for seamless DAW and hardware sequencer integration.
