“Good condition . Everything works as should .. Sounds great .” Link

” The Sequential Circuits Six-Trak Polyphonic Synthesizer may be labelled as a “beginner model” by the company, but the features and functionality make it a prime choice for any synth enthusiast. Built with 48 velocity-sensitive keys and the same Curtis circuitry found in the company’s more expensive models, the Six-Trak boasts six voice polyphony and six VCOs for solid lead, bass, and pad modeling. Throw in an expansive onboard sequencer and single knob for one parameter control to achieve a world of sound right out of the gate.

I’ve owned this synthesizer for 2 years and have had nothing but joy from it. The only reason I’m selling is so I can afford to buy… another synthesizer, of course. Comes with 99 great patches. You can edit those to make most sounds you might want. The sequencer is very simple but intuitive and includes some fun features such as multitimbrality (multiple patches at once) and volume for each voice. It’s also one of the few synths from this period that has full midi functionality, so you can plug it right to the computer or a sequencer. Overall this thing is in great condition. The wood panels are slightly scuffed on the corners but no actual damage. All buttons and keys work. You don’t wanna miss out on this 1984 polysynth! Does NOT include stand. ” Link

“For sale one Sequential Circuits Six-Trak synthesizer in very good working condition. It is a US voltage 110v model

All keys, knobs,buttons and sliders are original and working correctly.

There is some minor crackling from some of the pots and sliders when moved. It would benefit from a service but is being sold as is.

The front panel has minor marks from use, the side panels have some scuffs.”

“For your consideration: Sequential Circuits SixTrak.
Get the legendary Sequential sound without breaking the bank!
The SixTrak is one of the earliest synthesizers to boast midi as well as multi-timbrality. More features include an arpeggiator as well as a sequencer. All of this in a great sounding analog synthesizer. All keys, buttons and potentiometers work fine. The only flaw is the power cable which has started to open up at the point of attachment.(See images)” Link

“Up for auction is a Sequential Circuits Six-Trak vintage analog synthesizer. This model is notable for being one of the first multi-timbral synths, equipped with MIDI and an on-board six-track digital sequencer. The unit is functional with one exception; track 5 does not work. The other notes play. We are not experts on keyboards so there may be other issues we do not know of. That said, please know that you are going to have to have this repaired or use it for parts. There are NO returns. Physically it’s in good shape, with a repaired crack in the wood (see pics). Other than that it just has a few minor cosmetic marks here and there, typical of a 30 year old used piece of gear.” Link

” Up for auction is this vintage Six Trak Analog Synthesizer by Sequential Circuits Inc. I am just the second owner and have used it sparingly (probably less than 5 hours total – really !! ). It is in excellent condition and everything on the unit works (no issues). There are just a couple minor scratches on the back but other than that you would be hard-pressed to find one in better condition.” Link

“The unit is working but selling as is for parts, refurbishing. All keys and functions seem to be working. I did not check the midi ports. The on/off switch works but is incredibly hard to turn on/off. It appears someone replaced the audio out jack. It is missing one knob for speed and shows wear, notably some rust, a chip in the wood on one side, and upon close inspection the black keys on the left of the board are chipped in the back (where you can’t see) where there should be full “hooks” if you will that prevent the black keys from sliding or popping out of place. They are seated fine and don’t move at all but if they were pulled on they would dislodge-it’s easy to put them back and again, they are in place firmly and all work just fine. Rubber of the power cord at exit in back is frayed but internal wiring appears ok and provides power but power cord might need replaced. Overall cosmetics aren’t great but seems the electronics are good. Selling as is for parts, repair or refurbishing. (I’ll try to put up a video tomorrow so you can hear it).” Link

“I am selling the amazing and beloved Sequential Circuits Six-Trak. I have owned this Synth for about 2 years and have upgraded various areas of the Synth. Despite some minor cosmetic scuff marks due to its age, this Six-Trak is in pretty good shape. The right wooden side panel is broken and is something that can be fixed easily by applying some wood clue or by buying new wooden side panels for only $60 on “gmusynth” Some of the key features for my particular version of the Synth are.

1. Multiple Outs! This synth was modded so that all voices have their own output on the back. (AWESOME!)
2. I recently upgraded the Firmware from v9 to the latest version from tauntek v14.
3. Fixed some of the broken keys, (cosmetics)
4. Bought a new knob cap for the main volume knob (which I haven’t attached yet because the new knob cap needs to be modified, cosmetics)

You can read up on the new firmware version by googling tauntek SixTrackBug. This firmware version fixes a lot of the parameter issues with previous versions and adds some new features.” Link

“A Vintage Sequential Circuits Six-Trak Analog Synthesizer with Operation Manual. Synthesizer receives power, and to my knowledge, works properly. 49 keys. Model: 610 Serial # 610-003276. Dated from 1983 based on the publication of the Operation Manual. The Operation Manual has instrument instruction as well as a wiring diagram and play sheets all unused. A little bit of writing on the Factory Program List page.

The wood cabinet shows very minor blemishes on right edge, and a chip on the cabinet on the left side (see pics). Does not affect play.

Please see images to qualify the condition of the item.

The synthesizer will be properly packaged and shipped via USPS.

I bought this synthesizer nearly 10-15 years ago, and have barely used it. Time to get it to someone who will.” Link

“Excellent condition for a 30+ year old synth. I am the second owner (bought in 1990) and have kept this early production model in my smoke free studio ever since. Never gigged or toured. Great sounding unit with no issues. You can find the manual online which I highly recommend. This thing is surprisingly deep in its layering abilities. Sorry, no international bidders please. Good luck bidding!” Link

I don’t have the manual, but the Six Trak manual .PDF is available online. I recommend checking that out once you pick this up to learn to program this synth. The layering capabilities is what makes this synth so great in my opinion! Thanks for checking!” Link

“I’m unfortunatley selling this keyboard due to my current life circumstance, as im going travelling for a long period of time. I would love to pass this synth on to someone who will make the most out of this beautiful machine. I’m very saddened to part from this beauty, although i hope for somebody to continue making amazing music with it…. as its done for me 🙂 xoxo

Fully serviced and Working perfect, Great condition. Very easy to use, even if you’re a beginner
in my opinion no need for extra controllers to simplify the synth.

p.s. I must mention this has been used in some great sessions, with some A-list muscians at metropolis studio London…. Rhianna, Adele e.g
also left on the machine are some gems, really great presets (over 60+) which were edited and used by some top industry musicians.” Link

There is only one issue. One key is chipped and the black key is stuck down as you can see in the photo. The chip and spring are in the unit and should be easily repaired. This is your chance to own a classic! It will come in the original box even though the box itself shows its age.” Link

“Lovely analog synth. Almost museum quality as far as appearance is concerned with a couple of marks on the side woodwork.

Whatever anyone says about soft synths, there’s something about real warm vintage analog synths! There’s a warmth that digital synths just can’t do. See http://www. flitemedia .com /studio /sci-sixtrak/

Built with 48 velocity-sensitive keys and the same Curtis circuitry found in the company’s more expensive models, the Six-Trak boasts six voice polyphony and six VCOs for solid lead, bass, and pad modeling. Only issue is that the volume goes up to 9.5 or so then back to 0. Doesn’t affect me as my amp goes to 11!!” Link
