Sequential Circuits Drumtraks

“Today I’m listing a sequential circuits model 400 drumtraks drum machine from 1984.

I’m only selling it as I can’t really justify owning 2 of these just to save swapping EPROMs around!

It is In remarkably good condition for the age.

There are a few dings on the wood sides , not much mind and only minor marks and blemishes / corrosion marks here and there on the metalwork.

It is very clean throughout , no dust bunnies or spiders!

Iv tried to show the cosmetic condition in the pictures , do have a good look to make sure you’re happy.

More importantly it works flawlessly. ” Click here to visit listing on eBay

“Sequential Circuits Pro One Synthesizer Model 100 Sold AS-IS for restoration. It powers up. I am not familiar with these. I do not know history. I think it is from 1979. I assume the power on/off switch went out so the previous owner hardwired it on. The only way to turn it off on is plug/unplug. One key is higher than others. I opened it up and saw one pin on connector the 16 pin connector was broken off. (see photo) I may have done it opening it up. Those are the only things I noticed.

Sequential Circuits Six Trak

“SEQUENTIAL CIRCUITS SIX TRAK – Polyphonic Vintage Analogue Synthesizer.

The six track is one if the last attainable vintage synths with a genuine pedigree. whilst it lacks the chorus of the juno’s it has a more complex and nuanced set of sound parameters and once you add a chorus it really comes to life. on top of that it’s fully multitimbral with the ability to play all six voices independently each with a different sound.

for an early synth the midi implementation is really good with cc support across all parameters. which potentially makes it your sequencers newest best friend.

the synth is in really really good condition with a small scuff at the top which i’ve tried to photograph. it comes with the original manual, cheat sheet – actually i still have the ordinal box which is really tatty but may be of interest it even has the original sales receipt from 1987.

i bought this in the states so it’s a 110v but i’ve been running it happily off a step down converter for the past 2 years.” Click here to visit listing on eBay

Sequential Circuits Prophet 600

” Sequential Circuits Prophet 600 – Vintage Analogue Poly Synth – s/n 3660

An absolute classic poly synth from the 80s.

This one is in very good condition, not perfect, but very good. And it’s all working well.

There are some minor marks here and there which are to be expected from a synth of this age that has been used. Some little chips to the paint that have been coloured in (not by me) which show up when you look carefully. There are some minor scratches on the front panel but they are not glaringly obvious and a few marks on the top keys which might come off. The membrane panel is very good with no damage at all, and I have had no problems using it. There are a number of quite obvious scratches and marks on the bottom of the synth most likely from being on a stand.

The knob caps are all good except for the speed control (on the membrane panel section) where the white mark has faded. Everything functions as it should, buttons, switches, knobs, led display, keys, midi, etc.

The wood end panels have been replaced as the original ones were pretty worn. The new ones are thicker and look really great. I will include the original ones so you have the option of going fully original if you want.” Click here to visit listing on eBay

Sequential Circuits Prophet 5 Rev 3.3

“This is the legendary Sequential Circuits Prophet 5 (Rev3.3) analog synthesizer. I am theoriginal owner, bought it brand spanking new in 1981. It originally had one bank of 40 sounds, thena few months later, I got a call from Dave Smith, from Sequential Circuits, askingif I could bring my Prophet 5 in for a “FREE upgrade to rev 3.3”. They would add another 80 patches, (for atotal of 120 sounds), and a MIDI interface. I asked “What’s MIDI?” Heexplained that it was a new communication device they were working on thatwould allow synthesizers to talk to one another. So I said OK, even though I only had 1 synthat the time. Then, almost overnight, there was a plethora of MIDI devices – andI had one of the very first ones, direct from the guy who invented it. So, I bought another Prophet 5 and MIDI’d themtogether for the fattest live sound you could imagine. The Prophet’s unique sounds definitely propelledmy retro-band (Papa Doo Run Run) right up into the eighties.

In the early 80’s you couldn’t hear a song on the radio or see a band on MTVthat didn’t have a Prophet 5. TheProphet 5 defined the sound of the 80’s.

I retired both of my Prophet 5’s from the road to the studioin 1990, and since I only really needed one, I kept the original, and tradedthe other one for a Korg Triton (I should have kept the Prophet). In 2000, I moved on to all digital, and putthe Prophet in its case – there it would sleep for the next 23 years!

Jump ahead to 2023, I have a warehouse full of vintage bandgear, in immaculate shape, and it’s time to say goodbye to some of my oldanalog friends. I immediately got outthe Prophet 5 and fired it up. But alas,after a couple of decades the battery that was keeping the sounds alive wasdead. So I did some research and took themachine to a tech in Oakland, who specializes in Sequential Circuitsinstruments. He not only replaced thebattery, and reloaded all 120 factory sounds, but cleaned, tweaked, andreplaced other aging components, to make my Prophet like new again!

This is a very special instrument, that requires a very special owner. There aren’t many original 40+ year old PERFECTLYWORKING analog synths out there. If youare a collector, or you have an “Eighties” band, you’re gonna want this Prophet5. I’m asking $8900 for the machine,anvil case, and original Performance/Tech manual. (Make me an offer). I amlocal to the SF Bay Area, but can safely ship it about anywhere in the lower 48states for around $300. ” Click here to visit listing on eBay

” Aficionados will recognise this as a relatively early example with the “J-wire” keyboard. Apparently this is easier to repair than the later version.

I have owned this for nearly 40 years and never gigged it. After a long period of non-use I was pleased to find that everything appears to be working, although the keyboard is quite “clicky” and I noticed occasional re-triggering or slurring of notes. So you can have fun with it right away but for serious work I would strongly recommend a service. Cosmetically it is fine apart from traces of marker pen applied by me for security purposes, back when iI was living in a dodgy part of town. See the photos for details. As you will see, all the knobs and switches are present and correct.”

Sequential Circuits Prophet 5 Rev 3.2

“Up for auction is a Sequential Circuits Prophet 5 – Rev 3.2 Analog Synthesizer, Original Model 1000 from San Jose, CA .

It is in great cosmetic shape, except for one or two scuffs on the backside of the synth and works 100%. It was last serviced approximately Ten years ago here in Los Angeles. The synth does need a new servicing, as there are a few scratchy pots when turning certain knobs as well as the occasion key, hence the lower starting bid price. I hate to get rid of this beauty of a Synth, but times have forced me to sell my favorite Synth sadly.

One of the first fully programmable polyphonic analog synths, the Prophet 5 is the most classic synthesizer of the eighties! It is capable of a delightful analog sound unique to Sequential’s Prophet series in which the P5 was King! Five voice polyphony – two oscillators per voice and a white noise generator. The analog filters, envelope and LFO all sound great and are extremely flexible. The P5 had patch memory storage as well, which scanned and memorized every knob setting for storing and recalling your sounds – a desperately needed feature at the time! If you know the power of this synth, then you know how amazing the sounds that can be made on this beauty.” Click here to visit listing on eBay

The unit plays great! You can program patches and save them.The only problems I see are if you use the arpeggiator the notes will play a note lower!??Sequencer will record,but also play a note lower on playback..And the stack a/b won’t do anything.I have 2 of these keyboards.I bought them at the same time in the 80’s.Never changed the batteries(40yrs)!They both are doing the same thing..So maybe the battery has something to do with it.Batteries on Amazon are like $25.Not saying that would fix it,but strange they both are doing the same thing at around the same time.Other than that,it works great. Its in really great shape also!Check out the pictures,Most of the original sounds are still in there.Including some great stacked bass sounds. I bought caps for the knobs that give it a Prophet 5 look.They look very cool in the light..You can take them off,not glued.Unit sounds great…It just needs some effects…They didn’t give you that stuff in the 80’s LOL .Thank you for looking!!!” Click here to visit listing on eBay
