6trak “A classic synth in fair condition. The six trak needs to be tuned and there is a crack in one of the keys but otherwise the synth looks and sounds great. Feel free to message me with any questions. I’m quite reluctant to sell this synth but have come to the conclusion that I don’t use it enough to justify having it.” Link

6track “Apart a bit of dust here and there from my room (the white shadows you can see on the surface is only dust), you certainly won’t find an other model in this Mint condition. The previous owner was the first owner of the synth. He bought it NEW at the end of the 90′s (don’t remember the exact date). Crazy when you think it’s the first synth using MIDI from… 1983. I tend to believe it when seeing the condition of this unit. (Notice for example that the buttons are grey, their original color, not yellow or orange as you can see on all of the other units today.) This guy was a true compulsive collector and has pretty much never used, just keeping it like a piece of museum. I bought it this year, in April 2016. It’s a real pitty I had no time to used it more than 10 hours 4 or 5 times and have to sell it now.

It’s a bit sad because I love its dark funkyness and also its Boards of Canadaïsh possibilities for very moving and strange cinematic pads. Some people could compare it to a Matrix 1000, but it’s a different color and will fit perfectly if you have one (in that case, use it more for bass or leads, it will punch the pads of your Oberheim in a very nice interactive bread and butter way).

I like its “primitive” steppy filter which gives colors you don’t hear in other synths (nothing to see with the not-so-great stepping of the SE-1 I could compare). 1 OSC, like the 106, but darker, more unusual than the Roland which is “too popular” nowadays. If you want a sound that is different from the Juno’s (and all the emulations), it’s a seriously good and still cheap alternative.

Why the name Six Trak ? Because it’s poly-timbral and you can create and play up to 6 monophonic tracks (not tested, I like too much poly). Beware, the audio output is mono though. Or to play up to 6-notes like a normal poly. I was a bit scared about programming, but the buttons and the knob “value” work like a charm (and in Mint condition), and surprisingly quick to edit. There is an ipad editor for controling it too, and also a free vst WIN/MAC you can find on CTRLR.” Link

used sixtrak ” Very stable, all functions working. A few scuffs as with any 30+ antique, but general condition is evidenced by the photos.I have owned it for 5 or more years and upgraded the battery. All original save one knob. A sweet little synth with amazing analogue purity. Has been used in a smokeless studio, covered and protected from dust, etc. Quite a bit of fun if you want to experiment with its sounds. I have a PDF manual and quite possibly a technical schematic. On a scale 1-10 cosmetically 8.0. Sonically, 10. Functions 10. Buttons, switches, keys 9.9. (buttons in the edit section from time to time double enter, or at least for me anyway. (same thing happens when I’m typing, so it ain’t for sure it’s the machine). Pitch and Mod wheel 10.
This is an authentic Six-Trak, all original. This is a good investment and a fun toy. I am parting with it only because of limited space in studio. ” Link

Lots of custom programs, used primarily for bass and solo sounds, very fat in stacked mode. I taught it to say “Mama” (really!) Spent a week going over it and everything works fine. Reloaded lots of factory programs.”

p5 “This Prophet 5 is in good condition with some minor scuffs, scratches and blemishes.

It is 100% functional and has been overhauled top to bottom by a qualified and experienced synth technician.

All knobs and button tabs are present.

I’ve tried to show all aspects of the synth in the photos, if you need more detail of a certain area don’t hesitate to ask for more photos.

This is a Rev 3.0 which means midi is not standard (midi kits can be purchased from Kenton in the uk).

Some details on the work that has been done:

-All tantalum capacitors have been replaced (these are notorious for failure in synths of this age and this is an essential repair that would otherwise cost a considerable sum at a repair shop)
-All key bushings have been replaced (this means no clacking keys, smooth and soft key action)
-All key contacts cleaned
-Sample/Hold Logic chips and buffers replaced (common failure on prophet 5′s causing zipper noise when adjusting controls on the synth)
-Power Supply Overhaul (including new voltage regulators mounted off the PCB)
-Cleaned all pots and switches
-New back-up battery for patch memory” Link

six-trak “Selling all of my music gear and retiring from music. This listing is for a Sequential Circuits Six Trak analog polysynth in amazing condition!

Everything works as it should. All of the buttons, knobs, and keys work properly. Sends and receives MIDI without issue. Outputs are clean and free from noise or oddities. I replaced the internal “barrel” type battery myself about 3 years ago. It’s good for another decade. As you can see from the photos, it hasn’t leaked and the circuit boards are very clean (a common concern with this type of battery).

Cosmetically, this synth is also in great condition. There are some minor blemishes on the back…hard to capture with photos. The front and face are just about new looking. Only very minor wear in some spots. I replaced the wood sides with a pair I made myself. They are stained dark mahogany…a shade or two darker than the originals. Although I think they look fantastic, I’ll include the originals in case you prefer them instead (one side is chipped).

This synth excels in a variety of places. It’s not good for bass…wasn’t intended to be. But it is amazing at leads. It has a wonderfully rich vocal tone that just cuts through the mix. All six voice chips respond wonderfully. You can play in poly or stack them for that killer lead. The sequencer works well too. Alec Empire recorded his entire “Les Étoiles Des Filles Mortes” with this model so you can get an idea of the incredibly mystical tones it is capable of.” Link
