“Had this synth from new since bought in the mid 80’s. The keyboard was serviced by Cyberwave EMS last year and is in excellent working condition. Also in fantastic condition generally as you’ll see from the images. Free to collect of course but I will also deliver for free within a reasonable range of Gloucestershire. Would not recommend using a courier but can send insured if desired.” Click here to visit listing on eBay

“Overall good condition considering the age. All buttons and knobs operate. All keys operate. There is wear and tear that can be seen in the photos. This is a very vintage item, so please don’t expect mint condition, but it functions well and sounds AMAZING! It is a little dusty from storage and didn’t have time to deep clean, and that shows in the photos as well.” Click here to visit listing on eBay

“Sequential Circuits Six-Trak Synthesiser 1984.

This unit is in great condition and works as it should. Sadly the internal battery died so the synth is not storing patches or doing anything interesting other that powering up. Played fine when last used few months ago.

The battery is soldered in but could be replaced with a battery holder . Cheap easy fix, low bargain price. 100 patches can be reloaded via SYSEX bank dump as I have done in the past.” Click here to visit listing on eBay

“This is a joy to own but alas I cannot do it justice. Classic sounding from a time long long and they do not make them like this anymore. Studio use only and recent repair and upgrade.

Looks great with the odd mark and scratch which is to be expected. power is direct from the back to the plug. I have also printed out most of the manual (it is not the original). The joy of playing this is that it is 6 Note poly which was a rarity back then. Most of the tech spec is on line but if you are looking at this piece of history you will know all about it anyway.” Click here to visit listing on eBay

“This unit has been used.

This Six-Track is in great condition. It shows some minor wear from use and age. For example some light nicks and scratches. There is nothing major at all, overall it is a nice piece.

This unit has been thoroughly tested and we can confirm it is 100% functional.

Please be aware this unit is 100V. This means it MUST be used with a step-down transformer, not a travel adaptor. If you are unsure about this please let us know. We have some great, compatible step-downs for sale” Click here to visit listing on eBay

“For sale is a vintage Sequential Circuits Six-Trak. 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. This Six-Trak exhibits some heavy cosmetic wear like rusting on the chassis and scratches on the side wooden panels.

“Sequential Circuits Six Trak Analog Synthesizer Model 610 49-Key Keyboard.

6 voice polyphony and a looping real time sequencer make this synth super fun to play around with.

I just tested every key and button all of which are in working order.
It shows its age a bit, but its in pretty solid condition for an instrument from 1984.

This is one of the first synthesizers to implement MIDI.
MIDI sequencing I/O is supported but not all MIDI message types were established at the time of release.

Comes with 2 alternate firmware chips.
One of them is the same as the installed chip (sixtrackv9p) and one is an update (sixtrackv12).” Click here to visit listing on eBay

“Sequential Circuits 6-Trak.

Works fine. Great sounding synth.

1 x missing dial (can still be turned, parameter still works fine)

1 x scar on one wooden panel.

1 x Hum from within. Could be standard on this model of this age.

1 x slight rattle from within if I hold the synth and shake it. Not that I ever needed to do that, using it in the studio.

Lovely synth.”

“Please read all the description.

Sequential Circuits Six-trak analogue synthesiser. All fully functional and works fine. A couple of the numeric keypads need a firmer press and sometimes the 0 keypad will double enter(probably needs a clean), although it has been getting better with use (Synth has not been used for a while, hence clearout). All voices work fine(six of them), sequencer works fine and is great fun, arpeggiator is also fine, pitch bend and mod wheel also fine. NB the power cable had to be replaced and I did not have a rubber holder to secure it to the synth, so it is secured via tape.

There are some marks on the front panel consistent with age(see pics), but nothing to really detract from its good looks. Wood side panels are in nice shape I’ve entered a buy it now price to reflect these small things such as marks and the power cable (mentioned above).

Really nice sounding poly synth that can also be 6 multi timbral synths in one and also has a unison mode that allows for you to stack different presets on top of each other for immense room shaking sounds. It really does have a beautiful sound to it and is full of really nice presets at the moment.

The Tauntek ROM allows for quick and easy selection of the presets via the rotary dial, without the Tauntek upgrade you had to key in each preset number which soon becomes a PITA, so the Tauntek upgrade is a must.

Hope it goes to a good home and gets some use.

Item will be sent fully insured and well boxed. ” Click here to visit listing on eBay

” For sale, a Sequential Circuits SixTrak polysynth in full working order and great cosmetic condition. These synths are massively under-rated and no doubt will eventually appreciate in value the way their fellow eighties US-made polysynths did long ago. Six oscillators, multi-timbral with built-in sequencer and arpeggiator, what’s not to like? The only thing that lets it down is parameter editing, which is done via single data knob however there are external hardware add-ons that can transform this too.

This one has the latest v14 firmware installed – this allows you to select patches via the data knob (rather than by the numeric pad) and makes it much more fun to play with. It also adds a unison detune mode and a few other goodies.

This unit is in excellent cosmetic condition (only flaw is a very small chip on the left end cheek) and fully functional. It has just come back from Cyberwave EMS where it was given a repair and check-over. So now ready to be fully appreciated again.” Click here to visit listing on eBay
