“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

All buttons and functions are working, all 6 voices work, although the pitch bend wheel isn’t “linear”, it might need adjustment. Sequencer records and plays back etc…” Link

“This is 80s classic synthesizer in good working condition. It is a joy to use and has a huge variety of controls. Lookup this synthesizer on Google for a full list of features. 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

None of this affects the affect functionality of the synth, which is a thick and juicy joy! Has the unmistakable Sequential Circuits sound and oozes character.

“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

6t “Up for sale is a Vintage Sequential Circuits Six Trak Analog Synthesizer with Manual and Original Box. This synthesizer has been tested and tuned professionally verifying all functions of the unit are properly working. Model: 610 Serial # 610-000499. 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. If you never heard what one sounds like you will be impressed at the quality and unique sound that this instrument creates. Also included is a Sequential Circuits brochure.

Condition Issues: Wood cabinet shows minor blems on edges. Operation manual shows storage wear from being folded inside of box. Original box and foam packaging show storage wear but intact.” 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
