“Sequential Circuits Six-Trak 6 Voice Analog Polyphonic Synthesizer w/ Programmer.
In great condition. Recently serviced by previous owner. Synth works great! Keypad can be a little hard to operate but is to be expected of a keyboard this vintage.
However, you won’t really need the keypad with the addition of the programmer! I will include instructions on how to use. This really unlocks this synth’s potential.
You’ll own one of the greats! This synth’s brother is the Prophet 5. It’s filter sounds unlike anything else. This is a killer synth. Has the warm analog sound that we all go after as synth heads!” Click here to visit listing on eBay

Rock solid and stable, not glitchy like some vintage synths can be.

use it much and to simply raise money for a few other synths I would like to add to my studio.
It holds all its memory and patches, no problem, all keys play just fine.” Click here to visit listing on eBay
“For Sale/Auction is the Sequential Circuits Six Trak, 6 voice analog poly synth. This particular unit is in good shape for an instrument of it’s age. There are small signs of wear and tear, some scratches in the wood end cheeks, and a few dings on the metal exterior. The main volume pot does have a slight scratch to it, although I’m trying to clean that up before it ships. Also, the previous owner did a repair to the main tune knob, it’s either glued in place in a neutral tuning, or hard to move. This does not affect the synth whatsoever, merely mentioning it for the sake of honesty. Aside from these issues, the synth is working 100% normally, to the best of my knowledge. I have had this synth for over 10 years, and recorded with it in various smoke-free home studios.” Click here to visit listing on eBay

“Vintage Sequential Circuits SIX TRAK 6 , Analog Synthesizer with case! In very good cosmetic condition, but I cannot figure out how it all works. I have made patches and sometimes it stores them and sometimes not. Also cannot figure out how the sequencer works. All keys seem to work fine and I have been able to make some really nice sounds from string synth to weirdo harsh stuff. Maybe it has issues or maybe I just can’t figure it all out?
Thus selling as-is, no returns for less than market value. Case is an excellent fit and will make the shipping secure, but expensive.” Click here to visit listing on eBay

“This sale is in aid of my local Hospice Thrift Store, where I volunteer working on electronics. I sell items here for the store that don’t readily sell in house, alongside my normal vintage audio business.
Along with the more routine items that the generous donors contribute is the occasional gem and this is a fine example, a Sequential Circuits Six-trak.
I’ve occasionally dealt in synthesizers over the years but never had the pleasure of checking out an analog synth of this level. Fortunately the manual is available on line and I’ve checked every control and display, checking tuning, level controls, polyphonics, parameter change (I had a lot of fun with the glide parameter set to max and the arpeggiator), recording and playback, including getting two tracks recorded and playing back simultaneously. Audio output was clean.
I haven’t checked the midi functionality and offer no warranty in that respect, however you may draw the conclusion that a full check out as noted above makes that low risk. If you are local, I’d be happy to arrange for you to check out midi yourself BEFORE purchase.
This will be shipped carefully packed using closed cell foam (not expanded polystyrene) to secure and protect the keyboard.” Click here to visit listing on eBay
“Sequential Circuits Six-Trak Synthesizer w/ OSC Output Mod/New Firmware/Battery. Condition is Used.
Six-Trak synth in solid physical condition. Everything works, plays and sounds great. The battery has been replaced and all contacts have been cleaned. Surface marks & scratches are visible, and the mod wheel has a crack going across the surface. Please see photos. This does not affect playback or use.
The inside is a small DIY mess of wires and breadboards to make the separate outputs possible. If this is a concern, message me and I can open it for photos. There is some floor noise when using the separate outputs with quieter sounds, but a gate worked fine.
The mod output with a stacked & detuned unison really makes this synth unique and one of a kind. Unfortunately for me I’m moving and need to limit what I can bring.” Click here to visit listing on eBay

“Selling my Sequential Circuits Six Trak synthesiser. Is a great sounding 6 voice poly synth. This item is a vintage synth – was the first synth to feature midi – and as such has some scuffs to the paint and a chip to the side panel as shown. As a vintage synth be aware the tuning can also drift slightly, however this can be calibrated. Overall the synth sounds great, selling due to underuse. ” Click here to visit listing on eBay
“Sequential Circuits Six-Trak. 240v VCO synth. Plays perfectly. No audio problems that I could find. On the left-side wooden panel, it has cracked where the screw is and has been re-glued back on. Barely noticeable, but could come off again during transport. Also, the transformer emits an audible hum from the transformer. Not a biggy, but FYI. Defintely sold as is with any and all issues.” Click here to visit listing on eBay
