The ESP carries on the experimental spirit of MS-20 it allows you to use the pitch or volume of an external audio source to control the synthesizer. External signal processor (ESP) for processing an external signal 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. 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. 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. Self-oscillating high-pass/low-pass filters with distinctive distortion The VCA maintains the basic design of the original, but itвЂ™s been modified to produce less noise than the original. The MS-20 mini reproduces the distinctive synthesis of the MS-20 two oscillators with ring modulation, and envelope generators with hold and delay. 2VCO / 2VCF / 2VCA / 2EG / 1LFO structure In fact, the sound of the MS-20 mini has a somewhat bright and extreme quality to it because its sound is that of an original MS-20 in mint condition at the time it went on sale, before any of the components aged. A development team led by the original engineers themselves worked to recreate the original circuitry, and when it was necessary to substitute a part, these engineers made the decisions based on careful listening, in order to reproduce the original sound faithfully. The MS-20 mini painstakingly replicates the original MS-20.
