“Sequential Circuits Prophet 10 Rev 3 with Midi — In great condition! 100% functional! Looks great! Nicks here and there as seen in the photos. The left rear panel is slightly bent(previous owner) but does not effect functionality at all. Recently gone over by a qualified professional tech. Comes with 2 manuals and the US power cord. Sounds like 2 x Prophet 5s, so amazing!!” Click here to visit listing on eBay

“It would be difficult to find a better sounding or functioning Prophet 10 than this one. I have gone to great lengths over the years to make sure this machine was functioning optimally. It has NEVER been shipped the entire time I have owned it. I have always driven it to the synth doctor even if that means being in the car for 12+ hours. Whoever the new owner of this analog monster synth is, will receive it via freight. Professionally over-packed and strapped to a pallet with NO overhang of the box. This way no human can pick it up and drop it or stack anything on top of it.

I really like the sound of the Prophet 10, and much like the Yamaha DX1 is much more than two DX7s, the Prophet 10 is much more than two Prophet 5s. The way the two Prophet 5s are combined into ONE ergonomic and intuitive interface and controlled by the same micro processor is really inspiring (to me anyway). The Prophet 10 is also visually stunning in my opinion. It was always an instrument I aspired to own when I first saw it 30 years ago.

This P10 has recently been serviced by an expert on sequential products with 30+ years of doing so. At it’s last servicing I had the following done:

Cleaned all jacks and contacts

Replaced memory backup battery

Cleaned all internal connectors and treated all gold contacts

Re-lubricated all upper and lower keyboard bushings

Aligned all upper and lower J wires

Cleaned and burnished all upper and lower J wires

Cleaned and burnished all upper and lower Buss bars

Treated all gold J wires and Buss bars

Calibrated all 20 oscillators tuning and scale

Tested all auto tune and circuits functionality

Ran factory diagnostic rom all test = ok

Installed factory patches

Tested all controls, all keys, all functions, auto-tune, and playability

Cosmetically it looks great but has some flaws. The paint bubbles up in some spots on the back but is not flaking off. This is not very noticeable. This is also happening on my other Prophet 10. The face has some slight shadowing on the paint where studio/performance notes were taped to the front of it for years. At some angles you can see the wear from the adhesive, at other angels you can’t see anything and the P10 looks like it’s sitting in the showroom in 1981. Even though this machine is not mint, it is in way better shape than most of the P10s I see. (I don’t see very many because they only made 400 or so)” Click here to visit listing on eBay

“For sale is one vintage Sequential Prophet 10 analog synthesizer. There were only very few of these made. It’s one of the most powerful analog poly synths ever made! It was made famous by its use with the band Genesis in the early 80s. It’s more than just two Prophet 5 Rev 3s in one, it also includes a Sequencer and other features. I don’t think this unit has midi. I’ve listed this unit as “non-working” because it needs attention by the appropriate repairman who works on analog synths like these. Analog synths, particularly the old Prophets, require regular maintenance like key contacts being cleaned and other similar things that you’d have to take in anyway. So it most likely won’t cost much more to have it gone through and refurbished with a new preset battery (it’s lost its memory of the presets). I don’t know if the little mini casette for presets works or not. I think it does but cannot guarantee that anything works on the unit as I am selling this AS IS for a great price (notice a refurbished Prophet 10 is currently listed on ebay for over $12,000). However, I have to say that I am optimistic that this unit has very little to actually have to fix. I just had Tony Banks’ tech over at my studio and I’m tempted to have him help me fix it for myself to just keep instead of selling it. This is what I’ll do if it doesn’t sell. But, I also have limited time for repairs right now (working on funding touring and making music) and less and less space for my wonderful “Tony Banks rig” (you can see it on top of a nice CP70 for those who know the rig! I am also going to sell my Mellotron and RMI electric piano). So I am considering selling a lot of items I thought I wouldn’t sell because I love them. For this month I’m letting go of a certain number of them and they can go to new homes for people who similarly collect and enjoy rare vintage synths. ” Click here to visit listing on eBay

“Up for sale is my unique sequential circuits prophet 10 synthesizer. First the bad – the previous owner professionally chopped off the second keyboard from the unit along with the old sequencer. Consider this unit two prophet 5s with the ability to stack voices and create some of the best sounding synth tracks you’ve ever heard.

The good – this unit was fully serviced a year ago by Three Wave Music in NJ and everything is fully working and it tunes up great. The only thing off is that the contact of the second highest B flat is not working after having not used it much over the past 6 months but this should be an extremely easy fix. I haven’t been able to figure out the midi on this unit but that might just be not knowing how to get the channels set up right. Besides that she is beautiful.” Click here to visit listing on eBay

“Sequential Circuits Prophet 10 Rev 3 (CEM) analog synth VCO/VCF from about 1982-83, serial # is 324. Sequential Circuits did not make a huge # of these Prophet 10 synths, maybe a few hundred at most. This P 10 was just serviced by The Analog Lab in NYC and it had all issues that needed service and repair done. I have the repair work log showing what service was done to this P 10 analog synth. This P 10 has all 10 voices working and the auto tune function keeps the synth stable and in tune. There are 2 VCOs per voice total of 20 oscillators and a simple basic sequencer which works great, I believe it just uses some of the lower voices not all 10. The Prophet 10 is much more than just two Prophet 5 synths put together, these P 10s are rare and unique to an era when analog synthesizers ruled. You just do not see any modern synths like this P 10 anymore, and it is doubtful if any company will ever make something like this analog beast again. The micro cassette tape drive on the side of this P 10 does not work, as it was intended originally for the dumping of saved sequence patches. All the original SC factory patches were reloaded into this P 10, and this P 10 has early basic MIDI, in out and 32 patch memory. There are no dead keys in either keybed no missing voices, and no chipped or damaged keys either. No broken or missing buttons or knobs and pitch/mod wheels function perfect. The key contacts and bushings are in very nice working condition. This vintage early 1980’s analog poly synth is in good to more accurate very good cosmetic condition, and very good to more accurate excellent condition with the electronic components on the inside.” Click here to visit listing on eBay

“DESCRIPTION -This is a listing for a rare SEQUENTIAL CIRCUITS Prophet 10 Synthesizer w/Factory MIDI.

This may be one of the more cleaner Prophet 10’s that you will come across. If you are a gear nut who has to have your gear pristine, even your vintage gear, then you should strongly consider this epic analog monster. Another one like this may not come around for a long time.

Installed in this 10 voice double-stacked prophet 5 wooly mammoth is the preferred MIDI option, and an internally installed fan to keep those 20 oscillators just cool enough to singe your eyebrows.

Notice the cleverly upgraded cassette drive mounted on the left side panel.

Back in the days when the Japanese analog synths makers were still trying to put hair on their chest, this American made mastadon was putting hair on other places. #BALLS

PRICE. Yes, our price is crazy, but so is this synth. We are selling this museum piece for a collector who really does not want to sell it, but as they say, everyone has a price, and this is his. So we are pricing it within reach of those who really want something special and can afford the best.

“For sale is a vintage Sequential Circuits Prophet 10 analog synthesizer. This is one of the greatest analog synthesizers ever made, 10 voices, 20 oscillators, insanely huge phat sound! It’s like having two Prophet 5’s in one, but with a few added features like a built in sequencer, a 3 band EQ and keyboard modes like double and alternate. This is the later version with midi installed! Loaded with the original patches. I recently had it fully serviced, it is 100% ready to play and is fully functional. Only two minor issues barely worth mentioning; 1 LED is out on the Single switch (you can still tell which voice mode you are in; if you don’t see any LEDs light up, you are in the Single mode…it would take a lot of work taking the boards out to replace one LED so I didn’t bother getting that fixed). Also the side cassette mechanism has been disconnected inside, since it is unlikely anyone would bother saving sequences to cassette tapes that you can’t even find any more. Cosmetically it is in excellent shape, looks really nice. See pictures below for details. I also have a flight/road case that will be included, though the case is not in the best of shape, it still works well for transporting the synth safely. These synths are very rare, especially the later midi model and in such nice shape as this one is! Don’t miss out on this awesome legend! ” Auction ended. Click here to browse on eBay.

“This unit, serial number 1010-0078, is the final production version of the Prophet-10 designed around two Prophet-5 Rev 3 voice boards. It has enhanced microprocessor control circuitry and software to provide 10 polyphonic voices (2 VCOs each) in four keyboard modes with responsiveness comparable to the Prophet-5. These modes allow the choice of separate polyphonic control of two 5-voice synths, combined control of a “stacked” pair of 5-voice synths, alternating notes between two 5-voice synths, or control of a single 10-voice synth. Additional features not found on the Prophet-5 include programmable 3-band equalization, two control voltage pedal inputs with assignable routing, three foot switch inputs and a 10,200 note polyphonic sequencer. It is equipped with Sequential’s MIDI interface kit and the latest firmware, Rev 6.1. Recently the unit was thoroughly tested, repaired and burned-in by Wine Country Sequential in preparation for sale.

If you are familiar with the Prophet-10, you are probably wondering what happened to the keyboards on this unit. Although the stock Prophet-10 with its twin manuals is a sight to behold, the inclusion of two keyboards makes the nearly 3-1/2 foot by 2 foot by 8 inch, 70 pound unit so cumbersome that it is difficult for one person to move it by themselves, and difficult to integrate into a small studio environment or performance setup. As well, with the advent of MIDI controllers and sequencers and availability of the Prophet-10 MIDI upgrade kit, the built-in keyboards became redundant. At least a few ardent but frustrated Prophet-10 users dreamed of a slimmer instrument without the keyboards.

While I was employed as a service technician and visiting E-Mu Systems in the late 1980s, I happened to mention this to a product design engineer there who described to me a simple solution he referred to as “The Riley Mod.” It turns out that all the structural members forward of the main control panel can easily be unbolted and removed except for the sides of the chassis frame. The keyboards, modulation wheel and sequencer modules are simply unplugged from the rest of the synthesizer, unbolted and removed. Then the sides of the chassis frame can be cut back in line with the new forward face of the enclosure created by reusing a long corner piece and sheet metal that was part of the keyboard enclosure. Likewise, the wooden end pieces are carefully cut back to match the new enclosure dimensions and refinished to match the original look. Voila!

As you can see in the photos, the end result resembles an Oberheim Xpander, but with the familiar Prophet-10 control panel and no keyboards. This reduces the depth of the instrument to 13-1/2 inches and weight to 43 pounds – a much more practical size for lifting, transporting and integrating into an electronic music studio or performance system. For example, this slim rendition of the Prophet-10 rests comfortably on an Apex column stand.

NOTE: The circuit boards contained in the synthesizer unit are unaffected by the “Riley Mod” and have not been modified in any way except for installation of the factory-supplied MIDI upgrade kit. The MIDI upgrade and all servicing of the unit was performed by an authorized Sequential warranty service center. I performed the chassis modification while employed as a service tech at an authorized Sequential warranty service center, although this of course was not warranty service. In addition to the steps described above, minor modifications to the components removed from the original instrument were made to facilitate their continued use as separate modules. The Polysequencer was mounted in a custom enclosure made of sheet metal with wooden side panels, and the ribbon cable connecting it to the instrument was divided and terminated with cable headers so it can be connected by an extension cable. A selector switch was also added so that switching between internal and external clocks can be performed without unplugging and re-plugging the external clock signal cable. The single remaining keyboard (the other was sold) was mounted on sheet metal cut to the size of the keyboard’s footprint. An enclosure and external cabling similar to that provided for the Polysequencer was planned but no further work was done. The modulation wheel panel was prepared for addition of an external control switch but that and an enclosure with cabling were never implemented.

I am the original owner of this instrument and have kept it in smoke-free home studios or in heated storage at home. The instrument was used in a handful of public performances and has relatively little wear and tear. All rotary controls, switches and displays look like new and are in perfect working condition. The tape drive and Polysequencer are in perfect working order. All the white lettering on the control panel and black lettering on name plates is fully intact. Two of the four screws that attach the hinged control panel to the chassis frame are missing, and a nut for one of the screws is missing from the chassis frame, although the two remaining screws are sufficient to secure the panel. Some minor scratches or worn spots in the paint on the chassis and around the control panel screws have been touched up. Same for the Polysequencer. The instrument’s right wooden end panel has numerous light scratches and could be refinished to appear as nice as the left panel, which is still in very nice condition.” Auction ended.

“Sequential Circuits Prophet 10 Rev 3 with the Curtis chips, analog 10 voice polyphonic synthesizer serial # 91 manufactured around Sept. 1981 fairly rare and somewhat HTF in good working/cosmetic condition anymore, the synth in very very nice but not perfect mint condition.

No broken knobs or sliders or other controls anywhere at all. No broken or chipped keys on either upper or lower set of keys You can get all 10 voices on the upper or lower set of 61 keys or a mix of the 10 voices between the upper and lower two sets of 61 keys which gives a different option for musicians playing this keyboard /synth unlike other synths from that era with only one keyboard. The Prophet 10 has the early basic MIDI circa 1983 or so in/out only retrofitted by SC, according to the huge original SC owners manual with many updated addendums/refinements all done at the SC factory through 1982-83 which is included, also comes with 5 original SC foot pedals and a custom Ultimate brand A-frame type adjustable height stand to hold the synth, and a huge Anvil type heavy duty in nice condition flight case no bad foam with heavy casters which holds the aforementioned original SC P 10 synth as well as the original SC owners manual, and it also holds the 5 SC pedals as well as the orginal power cord. You can play this synth vertically as well as horizontally with this Ultimate stand if you prefer, or some custom angle in between that works best for the new owner standing up, or put it on a modern stand to sit down and play it. There are also several NOS rare original Curtis chips included, as backups for future replacements, that came with this synth when I bought it from the previous owner about a year and a half ago on ebay. The synth plays 100% , except for the obsolete tape drive for the poly sequencer, I have not used at all so I am not sure about the poly-sequencer,which is most likely in working order however, again I have not ever used the poly-sequencer myself. I had the synth checked out at a reputable pro music store Big Dudes in KC by the veteran analog/digital techs, and they could not find any thing wrong with the synth with the exception of the poly sequencer, which previous owner said he had not used in 15 years or so because of the obsolete tape drive used to record the sequencer notes, there was no mini-tape cassette on hand to test the sequencer. The mini-tapes may still be available at WINECOUNTRY.COM which still offers repair/servicing of the old SEQUENTIAL analog synths. All 61 keys x 2 sound as well all leds function, and the one tech spent a month at least checking out the VCA and all the filters ,oscillators, ADSR envelopes, presets, etc with the proper test equipment. The synth does take about 10-15 to properly warm up though. ” Auction ended. Click here to browse on eBay.

No dead keys or voices, and there are no broken or missing knobs, buttons or controls anywhere The synth functions 100% except for the onboard poly- sequencer and obsolete micro-cassette tape drive, which may work fine but, I have not used them at all so I, cannot really verify that this section of the synth is 100%. I am not sure but I think you can also use newer modern MIDI compatible external sequencers with this prophet as well, again I do not use sequencers, but this version of the P 10 is more collectable because it came with the factory onboard poly-sequencer, whereas some of the P 10’s did not have them. The synth needs a few minutes to warm up and the autotune works proper. The factory presets on the synth are the original as far as I can tell but I am not 100% sure of this, though you have the option to overwrite the existing ones with a new cassette tape of the SC Prophet 10 original factory presets purchased from WINE COUNTRY, which still offers repair/support for the old SC synths. ” Auction ended.

I will spare you the specificications of this vintage synth, but will add that it lives up to its reputation = Good for studio, Not so good for going on the road 🙂

I am the original owner. I bought this about 30 years ago. The SCI factory MIDI interface was installed around 1983 by OmniTron located inside the BrookMays Music Store in Dallas (which makes the original Voltage/Gate sequencer interface on the back non-working). About that time I also had OmniTron update it to the Braemar Tape drive which removed the original front drive.

Then SCI was aquired by Yamaha = 🙁

In 2010 the keyboard keybeds (J-wire contacts) and audio interface were service by Audio Electronics in Dallas so there is good action/contact. In 2011 I had them send one of the internal boards to Wine Country for service to make all 10 voices excellent.
