Genuine 1980's monophonic analogue synth by Sequential Circuits. This synth has been cherished but unplayed (literally) for decades! Recently brought back to life with a full service by 'Synth Doctor', retro-enthusiast and friend - Dr. Chris Powell - Oxford: the keyboard contacts have been cleaned, a faulty oscillator replaced with an original CEM-3340 chip and the system 'tuned'. All features are fully functioning, pots and switches are clean from scratch/noise. This synth has the serial number 7274 and was bought by my brother in 1981 (?) from Biggles Music, 85, West Street, Bristol and it moved to Oxford with me in about 1984/5 when he upgraded to a polyphonic and his Mrs 'insisted' he found it a new home. It has never been 'gigged' and was used to provide 'space whispers' and sequenced backing effects (a la Gong/ Daevid Allen) on a couple of music projects. Thereafter it's been tucked away safely in a cupboard for a good 20 years. It can programmed using the 40 - note sequencer in step time - but spaces can be added to give simple rhythm effects - these can come into their own when the synth is hooked up through an echo unit - and I've discovered awesome baselines and 'groove riffs' this way. ...oh...and it has the original manual, (very much worse for wear however) with some of the patch blanks filled in. There are some blanks too which can be copied - they're useful for remembering the following day just exactly where the switches and pots were when you discovered something awesome in the early hours... This is listed as buyer to collect, however, I would deliver in a radius of 100miles or so @ 40p/ mile (to include both ways) or check out delivery options via courier at the buyer's expense and risk.

It comes from the same period and genre as the Roland SH-101 and Moog Prodigy . The Pro One was basically Sequential's attempt at taking their legendary Prophet 5 poly-synth and packing it into a compact, inexpensive, monophonic analog synth! It has two VCOs, a great 4-pole lowpass filter, two ADSR envelopes (one for filter), and a compact three-octave keyboard. With a Pro-One, you can easily create punchy analog bass-lines and leads or quirky analog synth effects.The Pro One is an extremely flexible synth with lots of modulation possibilities (ie: the filter, VCO B and LFO can modulate VCO A or B frequencies or pulse widths, or the VCF). There's also an onboard sequencer, something common on many Sequential synths but not often found on other monosynths of the time. It is very basic, however, storing only two patterns and up to 40 notes max. Also, only pitch info is recorded (and in step time only); you can not assign a note duration to any notes. So it's basically a short melodic sketch-pad...but useful. Also onboard is an arpeggiator which has UP and UP/DOWN patterns. The Pro One is relatively simple and intuitive to use, fun, educational and responsible for some of the coolest and hardest basslines in electronic music today! It is used by Hardfloor, Überzone, the Prodigy, Cirrus, Fluke, Depeche Mode, Download, Banco De Gaia, Vince Clarke, New Order, Freddy Fresh, Mouse on Mars, Prince, Soft Cell, Richard Barbieri and Sigue Sigue Sputnik . read more
