This is the classic Korg M1-R rack synthesizer. - One of the best selling synthesizers ever made.
It was Korg's answer to the Roland D550 (D50) and uses similar principles to produce its sound. That is, it uses digital samples as it's foundation.
The Korg M1(R) was the first ever music 'workstation' in that it includes a multi-track midi sequencer and digital effects. - You can compose a whole tune with just this equipment, an amp and a midi-controller.
This particular unit is in very good condition and full working order. There are a few minor scratches here and there, but it is in generally good cosmetic condition.
I have printed the full manual from the internet and bound it in a proper plastic folder, so I will include this along with the power lead.
I will post to the UK only and will accept payment via Paypal only.
