Korg MS20 Mini White

Faithful Recreation Of The MS-20

The MS-20 Mini has been painstakingly reproduced by the development team that produced the original MS-20, taking care to recreate the original circuitry for a faithful reproduction of the original sound. The rich and bright tone the MS-20 Mini produces is down to the internal circuitry, designed to produce the sound of the original MS-20 in mint condition before any of the components aged. The dual oscillators both feature ring modulation and envelope generators with hold and delay functions. The VCA is based on the original design but has been modified slightly to minimise the noise it produces for improved overall audio quality.

Self-Oscillating Filters

One of the most revered features of the original MS-20 was powerful filters, with the MS-20 Mini retaining these self-oscillating filters, providing resonance for both the high-pass and low-pass. The process works by maximising the resonance, in-turn causing the filter to self-oscillate and produce a noticeable change in tone. Fans of the MS-20 may know that the filter circuit was changed through its production cycle, with the MS-20 Mini opting for the earlier filter, designed for a superior and more radical sound.

External Signal Processor (ESP)

The External signal processor of the MS-20 Mini gives you the ability to use the pitch or volume of an external source to control your synth. The experimental nature of the ESP functionality, opens up a new world of flexibility, allowing you to input instruments such as electric guitars and use the MS-20 Mini as a guitar synthesizer, or attach a microphone to change it to a vocal synthesizer.

Flexible Patching System

One of the most prominent features of the MS-20 Mini is its highly-flexible patching system. The patching system located to the right of the panel, gives you the ability to create complex new sounds by changing cables between connections. Allow your imagination to run free with its countless combinations between modulation, triggering, samples and noise generators; allowing you to produce a wide palette of tones and sounds. The accompanying flow chart allows novice users to easily take advantage of the patching system, giving you a crash course in synthesis straight out of the box.

Design & Connectivity

The compact yet highly robust design of the MS-20 mini makes it perfect for studio and live performances alike. This mini version of the original MS-20 has been scaled down to 86 percent of its original size. The keybed features 37 notes in total, spanning three octaves for added versatility. In addition to its analog design, the MS-20 Mini also features USB & MIDI connectivity, ideal for using your MS-20 Mini with your favourite DAW, allowing you to incorporate its rich, warmth into your productions.
