Description
The black MS-20 Mini from Korg is a fully functioning analogue synthesiser featuring the circuitry of the iconic, late 1970's MS-20 synthesiser, but shrunk to 86% of the original size. Its versatile patching options, analogue filters, and the ability to process external signals makes this diminutive powerhouse very attractive to the analogue synthesiser aficionado.
A development team led by the original engineers strove to painstakingly replicate the MS-20, both in sound and form. The sound comes from an architecture featuring two oscillators (one with ring modulation) and envelope generators with hold and delay. The VCA (Voltage Controlled Amplifier) maintains the basic design of the original, but has been modified to produce less noise.
High- and low-pass filters with resonance and distinctive distortion can deliver radical sounds when they are pushed into self-oscillation. Additionally, external sources such as an electric guitar or vocals can be used to control the synthesiser or have the source manipulated by the filters. A flexible hard-wire patching system provides nearly endless possibilities.
The synthesiser features a MIDI In jack for receiving note messages, and a USB-MIDI connector that can transmit and receive note messages (there is no velocity information). Connecting the unit to a computer allows it to be triggered from a sequencer.

My School had an original version and I would mess with it all the time creating new sounds and patching up the various stages to see what they did. It's a good way to learn synthesis and amazing what the range of sounds you can create is. Unfortunately the originals were kinda scratchy and the keyboard wasn't all that nice to play. This thing is great value for money and benefits from modern parts.Read more Read less
