Pro One, Sequential Circuits @ 31 August 2017, Comments Off on Sequential Circuits Pro One

“Here we have a Sequential Circuits Pro-One Monophonic synthesizer, a rare Vintage 80s Analog synthesizer made between 1981-1984

It has been cared for in a smoke-free studio environment and never gigged (by me). Cosmetically it is a 9/10, everything looks fantastic.

Functionally it is an 8/10, everything works and sounds great but most of the pots and switches are crackly and need to be cleaned.

Once you dial in a value it’s fine, it’s only when turning/switching you hear some crackling. (some cleaning of the potentiometers/switches should take care of this.)
I also just had the bushings changed out before listing it, and one key is a little higher than the others (see pic) but this doesn’t affect its playability at all.
I hate to part with this one, it just sounds incredible, but I need to sell it so my loss is your gain, low starting bid and a short auction so don’t wait!” Link

Arguably the standout synth for bass, leads and pads ever. This machine is a monster!

Mine has been upgraded with the Turbo CPU Midi and is in immaculate condition with zero faults.” Link

“I’m selling my Sequential Circuits Pro One. It’s in excellent condition and sounds unbelievable. This is the model with the J-Wire keyboard which has recently been serviced and works perfectly. The little rubber cover on the audio output jack popped off and I can’t seem to find it in my studio, this does not affect the audio output at all, it’s purely cosmetic – guaranteed!

All knobs, buttons, wheels, keys, etc… work perfectly. It’s in excellent condition and sounds incredible.

I’m also including my Kenton Pro Solo Mk II MIDI to CV interface which allows you to sequence the Pro One with a DAW.

This synth has been kept in my smoke free home studio, so it will arrive smelling clean.” Link

“I had this on auction previously but pulled it, some keys needed a clean after storage , which has now been done. A nice Pro One, the unit was overhauled and serviced by the KSR synth guru. The J-Wire keyboard was rebuilt and re-bushed, There are new wooden cheeks and no damage to any of the knobs. At some point a Kenton Midi kit has been fitted, this is one feature I have not tried out. ” Link

sci_pro_one_syntth “Location: Barnet, North London
Asking price is £1790 as these rarely come up for sale, open to sensible offers.
Pay on collection, you can collect or delivery is free in the U.K. can ship overseas on cleared funds at cost to the buyer.

Lovely and well cared for example of the Pro-One synth. Bought this over 12 years ago from well know synth supplier RL MUSIC (look them up on google) and it’s recently been serviced and inspected by their team at KSR in London.

I don’t use this much anymore, fully digital these days, so would like to give it to a good home, it’s had studio use only and in excellent condition, the wood panels look great with some small marks to them but overall this synth looks fantastic and more importantly sounds fantastic.

I’m quite sure I have the original manual in storage which I will locate for the buyer but cannot promise I’ll find it.

This synth is also a great investment piece and will only increase in value over time.

Thank you” Link

” Up for auction my Sequential circuits pro one, a 2VCO monophonic synth from the early 80’s. The overall condition is good for an instrument of it’s age, and it sounds great! Although I am prepared to post this if absolutely necessary, I would far prefer any buyer to collect this instrument in person, due to the value, age, and fragility of classic instruments. Happy bidding!” Link

However I mostly sequenced it with a hardware sequencer. I just spent $300 to have it fully gone through at Perfect Circuit Audio here in Los Angeles. It sounds dreamy. I am selling in order to buy a OB-6. I’ll miss this synth but I need a poly. ” Link

sci pro _one “This is an original Pro One with a 37-note J-wire style keyboard. I have installed new Pratt & Read rubber bushings for the keys, and have kept this synth stored in my closet for the past 12 years. I also recapped the power supply and reflowed all the solder joints when I acquired the keyboard for my personal home studio. The previous owner drilled two holes in the case (see photos) for reasons I never understood. It never really bothered me, but could be a perfect location for MIDI in/out should you choose to go down that path.

I have just tested all keys, knobs, switches and both pitch wheels with my headphones, and all work great! Also included are the original operating and technical manuals. Both have been written in (original owner again), but are otherwise in fine shape.” Link

usedpro_opne “For sale is my Sequential Circuits Pro One vintage analog synthesizer. This has the more desirable J-wire keyboard (serial number #100-3142). It’s in nice shape and working great. The only thing not working is the Noise knob in the mixer section. Everythign else is working, but in general it could use a servicing/tune-up. All the keys do trigger currently but the keyboard is clacky, so a rebushing would make it play smoothly. Some of the switches are dirty and knobs are scratchy. Otherwise it looks to be working as it should, and has a great sound. The Pro One is almost like a monophonic Prophet 5 but with a few extra features like the sequencer, arpeggiator and mod section.” Link

up1 “Selling my beloved Sequential Circuits Pro One to free up room in my studio. The synth has been recently tuned by a reputable technician. Due to the nature of vintage instruments, the synth is sold as-is, no returns accepted.

Issues:
1. This unit features the membrane keyboard (this is not a J-Wire model). These keyboards all trigger pretty unreliably, so I recommend you play the synth via CV/Gate.
2. The key bushings need to be replaced. I have a new set I will include with the synth (pretty simple procedure to replace them). Doesn’t make a difference if you’re playing over CV/Gate due to the issues with the membrane keyboard, however.
3. Tuning is a bit flat when playing via CV (but tracks correctly across the full range). Not really a problem per se, just adjust the osc tuning accordingly.” Link

sci_pro_one “This J-wire Pro One was serviced on 11-30-16 by Greg Montalbano via Music Technologies Group.

Routine service included pots, switches and key contacts cleaned, bypass caps were replaced, and the synth was tuned & scaled. Furthermore an IEC Power Connector was installed, Key Bushings were replaced, and the MTG MIDI Mod was installed (Midi In, Out and Thru)!

The serial number is 4566.” Link

por-one “This Pro One is one of the first 1000 made(677). It is in VG cosmetic condition and sounds outstanding. The outputs and potentiometers are static free and turn smoothly.

One key has lost its bushing and sits a little higher in the key-bed than the others. It is a little loose upon being struck and wiggles a tad. The key does still work. The bushing costs a few bucks at Wine Country.

Owners manual and Service manual are included in a binder.

I have described this item to the best of my ability and therefore cannot offer returns on this item.” Link

sciproone ” This Sequential Circuits Pro-One is in amazing condition and fully functional, and is Midi-Capable via INCLUDED Vesta Kozo Midi-CV converter. It is a fully and professionally restored Late-Model with fully-functioning Keyboard. This is all-original, with NO modified circuitry or re-soldered components. All rotary pots and switches have been professionally cleaned. All key contacts on this later non-J-wire model have been restored and functioning. Everything works and sounds great. While no vintage synth is ever “truly” mint or perfect, this one has been well cared for and not cosmetically re-finished. Incredibly clean unit inside and out. Original Power cord (does not use AC wall adapter).” Link

1 “This is the original Sequential Circuits Pro One, serial #5510, with the preferred J-wire key action. All the knobs and switches have been de-oxidized and run as smooth as silk. Each key’s J-wire connections have also been carefully cleaned and de-oxidized and work perfectly. There is on key, the second C key from the bottom, that is still a little scratchy if the key is released slowly, but works perfectly in normal playing conditions. The orginal key bushings have all been cleaned and all the keys are even.

This comes with, and will be shipped in, a perfectly fitting Pelican 1650 case with wheels and is perfect for storing the insturments or taking it out on gigs. I purchased this instrument in 1993 and am the second owner. Since then it has been in my smoke-free studio or in temperature controlled storage. I have just given it a thorough cleaning and it works and sounds totally great.

As with all of these vintage Pro Ones, there are a good number of ways to interface it with other analog voltage controlled devices, including all the modern modular Eurorack gear (with a simple 1/4’ to 1/8” adaptor). There is basic CV in and out, gate out, gate/clock in, and filter CV in. There is also an audio in plug so you can send external audio through the Pro One’s great sounding filter. As I’m sure you know since you are here, this is a monophonic instrument but it does have a very cool appreciator and a very basic, but still cool, two position sequencer. This is basically the (one voice) little brother of the Prophet 5. (Thus the “Pro One” name.)” Link
