Sequential Circuits Pro-One

“The original Pro-One monophonic synthesizer from 1981. Please refer to online reviews of this legendary instrument for detailed technical specifications. Suffice to say this is a classic analogue synth with extensive modulation capabilities, powerful filter with the SCI unique resonance, two oscillators, sequencer and arpeggiator. There is only one Pro-One in terms of build and sound quality; naming no names, recent clones are decent enough machines but simply that: machines rather than instruments. It was mostly triggered by a MIDI converter box rather than played direct during its working life, so the keyboard is responsive and without the triggering problems which some examples exhibit. There are slight though noticeable abrasions on the right-hand wooden sides (see photos) but otherwise it’s in a fine condition.

The Pro-One sound can be heard on recordings by artists as diverse as Vince Clarke, Michael Jackson, John Carpenter, and many others. It’s an absolute beast if you’re producing Techno or House.

This example has been kept carefully in storage since the early 1990s and has recently undergone an extensive service and overhaul by the Synthesizer Service Centre, London NW10 (invoice document included).
