Sequential Circuits, Six-Trak @ 22 November 2018, Comments Off on Sequential Circuits Six-Trak Project Machine
” We purchased this a number of years ago (over 20) and used it in our little home studio and unfortunately is not working at present. Not sure of the repairs needed – we are just trying to clear things out so are selling this classic unit as is. It is clean with not much wear showing but alas, it is non-operational.” Click here to visit listing on eBay
“This unit has some minor cosmetic wear and tear from over the years. A little on the face plate and some on the wooden side panels. Please see all photos. Overall is a really nice synth and minor cosmetic wear does not detract from usability.”

“This is for a used Sequential Circuits Six-Trak Vintage Analogue Synthesizer. The body is in decent shape has some nicks and scuffs as shown in picture but nothing major. Keys work perfectly, sounds awesome. The speed knob works fine but i think it has been replaced as it’s a little wonky but still works fine(right knob shown in picture) The 6 key works but sometimes needs to be pressed hard and last-the rubber around the end of the outlet plug is starting to degrade as shown in picture. All that said still works good and sounds amazing.” Click here to visit listing on eBay

” Due to emergency, need to sell some synth stuff. Up for auction is one Sequential Circuits Six Track Synthesizer. This synth is functional and sounds beautiful, but has some issues. First, the rubber chicklet buttons are terrible, they should be replaced. Sometimes you can get them to work. Second, the power switch is stuck in “ON” position. Good news is it also comes with some extras. This auction includes the Sequential Circuits foot pedal switch. This switch is a helpful assist to work around not having to use some of the very finicky buttons. This unit has been upgraded with the Wine Country IC, so it handles standard MIDI. I’ve included the original chip in the tube the upgrade came with. I’ve also included some other Wine Country paperwork and a new capacitor. Despite the issues, I know this machine makes beautiful sounds, but due to personal emergency cannot test all other functionality and this synth is being sold “AS IS.” Thank you.” Click here to visit listing on eBay

“This is a 1983 Sequential Circuits Six-Track six voice analogue synthesizer. It is one of the first analogue synths to include MIDI in and out and has 64 preset sounds. It has six voices that can be stacked individually as well as plays with six-voice polyphony. I am including the original manual. Because of it’s vintage nature it is being sold as is. Everything is tested and working.” Click here to visit listing on eBay
“For sale is a Sequential Circuits Six-Trak analog synthesizer. Cosmetically the synth is in pretty good condition considering it’s age with only minor scuffs and blemishes, however whenever you throw midi at it it begins to act up, either dead voices start appearing or it cuts out completely until you resit the battery. For this reason it has to be under for repair.” Click here to visit listing on eBay

“This is a Sequential Circuits Six-Trak synthesizer in great working condition. Multi timbral synth with advanced early MIDI capabilities. You can multi stack to get monster analog sounds. It’s got some really nice custom made looks like birch ends. This is the Japanese 100VAC version but the studio I got it from insisted they always used it at 117VAC without issue. I contacted Wine Country because they sell a US transformer for this for only $10 and David Sesnak formerly of Sequential Circuits, emailed me back and advised it’s not necessary, these 100VAC Six-Traks work fine at 117VAC.” Click here to visit listing on eBay

“Ive put in a good effort trying to get this thing fixed, but I think it’s time to pass it on. Essentially, the main issue is that the sixth channel is screwed up. This usually manifests by not producing any sound whenever you hit a note on the six channel, and unfortunately, it’s kind of unpredictable which you know will be on that sixth channel. You can partially correct the problem by setting the voices to monophonic, but that ruins a lot of the fun. Additionally, some of the numeric buttons aren’t working very well.
The last guy that took a look at it gave me a description of what’s going on. I’ve quoted him below.
“Its pretty beat – membrane switches are pretty shot, something is busted in channel 6 and the case is rough. (…) All 6 of your chips are good, it’s something else in channel 6 not the synth chip. The chips are CEM3394″
He’s encouraged me to sell it for parts since he believes a repair of this particular unit might be kind of difficult. Of course, that’s just one opinion.” Click here to visit listing on eBay
