# Sequential Circuits Pro One

Pro One, Sequential Circuits @ 14 March 2019

“Up for auction is my Sequential Pro One vintage analog synth w/MIDI in near mint condition. It has the more desirable j-wire keybed which has been painstakingly refurbished.

What has been done:

MIDI kit installed. Simply connect a MIDI cable from your controller or sequencer to the MIDI IN jack. Hold the red button down to enter MIDI mode. Send the kit a MIDI note and it will respond on that channel from that point forward. A red LED above the pitch/mod wheels indicates whether or not it is receiving MIDI. CV/GATE can also be used.
Keyboard bushings replaced, bushings greased, j-wires polished, every key removed/cleaned/polished, and keybed painstakingly adjusted to perfection (both height and width). Each j-wire adjusted so that they hit the buss wire at the same time for more accurate keyboard response. Keyboard now plays like butter. I have extensive experience refurbishing pratt-reed keybeds and took extra care to make this synth play like a dream. This easily took 4-5 hours of painstaking work to complete.
Prophet-5 knobs with metal caps installed. Paint on caps is absolutely perfect, with no scratches.
Every knob removed and cleaned with a toothbrush to get all the dirt out of the cracks.
Wood panels removed, sanded, waxed, and hand-rubbed to bring out the grain.
Pitch/Mod wheel plastic replaced with NOS wheels from Wine Country. The old ones crack over time and can slip on the pots.
All pots and switches cleaned.
Power cord replaced with a much nicer panel mounted 3 prong IEC power receptacle. Makes it much easier to remove from a stand (power cable included).
Inside and outside of synth completely cleaned.
Synth voices calibrated and checked over for tuning stability up and down the keyboard.

I own two Pro-One’s, and this one sounds the best of the two. It stays in tune up and down the keyboard. Pots have been cleaned but a few might be scratchy. I will retest before shipping. Not sure why this one has such a nice rounded, thick character to it but I prefer the sound over my other Pro One. Physical condition is very clean, near mint. The wood panels have some nicks and dents here and there, and small holes where knots are in the wood. Every knob cap is pristine. Every knob has been cleaned. A few scratches on the front panel. See photos for details. Only selling to fund another purchase. I am very picky about my gear, and have refurbished this to as close to perfect condition as possible.” Click here to visit listing on eBay
