KORG Mini MS-20 Korg’s MS-20 monophonic synthesizer, first introduced in 1978, is still a coveted instrument to this day, thanks to its thick, robust sound, its powerful, iconic analog filter, and its versatile patching options.  Over 300,000 people have enjoyed the distinct MS-20 sounds from the original, from Korg’s MS-20 plug-in synth, and the iMS-20 iPad app. Today, the sounds of the MS-20 have been reborn as the MS-20 Mini. The same engineers who developed the original MS-20 have perfectly reproduced its circuitry and fitted it into a body that’s been shrunk to 86% of the original size, yet retains the distinctive look of the original that remains unfaded despite the passage of time. The MS-20 mini will amaze you with its absolutely authentic analog synth sound. The MS-20 mini reproduces the distinctive synthesis of the MS-20; two oscillators with ring modulation, and envelope generators with hold and delay. The VCA maintains the basic design of the original, but it’s been modified to produce less noise than the original. Self-oscillating high-pass/low-pass filters with distinctive distortion One of the greatest characteristics of the MS-20 was its powerful filters, which provided resonance on both the high-pass and the low-pass. Maximizing the resonance would cause the filter to self-oscillate like an oscillator, producing a distinctive and dramatic tonal change that was acclaimed as inimitable, and was later used on the monotron and monotribe.  The filter circuit was changed mid-way through the production lifecycle of the MS-20; the MS-20 mini uses the earlier filter, which was felt to be superior due to its more radical sound.
