8sedmultitrak “• This is an American unit running at 110v so uses a step down converter for use within the UK (included).

• The only minor issue I can find is that one of the keys is not as responsive as the others. It does work but needs more pressure than the others – nothing a good clean or professional service couldn’t sort out. Please feel free to come round and fully examine and test out if you are interested.

What’s Included:” Link

6-trak ” This vintage analog synth was purchased new in 1984 and has had one owner. It has one damaged, but fully functioning key. Otherwise, the synth is in very good condition.

- Six-voice multi-timbral hybrid analog synthesizer with six-track sequencer
- Polyphonic and Unison modes
- Four-octave keyboard
- 100 user-programmable instrument programs
- MIDI” Link

mt “Selling this synth as is for repair due to pitch bend and chorus problems. Pitch bend works for a strange reason only when controlled from an other keyboard via midi and chorus makes weird noises or have no effect from time to time-although it can be turned off by a chorus on/off button and the synth played without it. Coming with original Sequential E-170 power supply. Again, the synth is still very nice and useful, I would list it as a “used” if not one recent jerk who was attempting to return another “working with limitations” item simply because he did not read the description carefully and changed his mind. So, selling it as is “for parts or not working”, no returns accepted.” Link

pt8 “This here is rare and amazing synth. Prophet T8 in GREAT condition!!! 9/10. This synth has after touch, midi, 8 oscillators (opposed to the P5′s 5 oscillators)… The ability to stack patches makes this synth a gnarly Prophet 5 on crack.!!! it also can come up with some very interesting sounds of its own. Down fall is that it’s huge, and old, you wouldn’t want to gig with this. It is a studio synth. Kept in a smoke free studio. Dope, Rare synth. Local pick up welcome! And I will ship. ” Link

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

Probably about as close to new as you can get. Includes power cable and original box.” Link

mt “For sale is my Sequential Circuits Multitrak. This is a rare classic vintage synthesizer and in my opinion very underrated, much better than the more readily found Sixtrak. It has a awesome analog sound along with a cool built in arpeggiator & sequencer. Awesome for pads but also gets very beefy in mono-stack mode. This might be the nicest Multitrak you will find. It’s in super MINTY shape, even the bottom is almost perfect. It has custom wood sides and looks and plays perfectly. Includes power supply. Be sure to check out the detailed pictures to make sure you like it. Don’t miss out on this awesome SCI synth!” Link

This piece has been serviced and tested, but the new owner may benefit from a more comprehensive inspection. This Prophet-5 is 110/220 VAC voltage selectable and comes with a Hosa FSC-502 foot-pedal. See photo’s for additional details.”

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

usedpro_opne “For sale is my Sequential Circuits Pro One vintage analog synthesizer. This has the more desirable J-wire keyboard (serial number #100-3142). It’s in nice shape and working great. The only thing not working is the Noise knob in the mixer section. Everythign else is working, but in general it could use a servicing/tune-up. All the keys do trigger currently but the keyboard is clacky, so a rebushing would make it play smoothly. Some of the switches are dirty and knobs are scratchy. Otherwise it looks to be working as it should, and has a great sound. The Pro One is almost like a monophonic Prophet 5 but with a few extra features like the sequencer, arpeggiator and mod section.” Link

The P600 has two oscillators per voice with sawtooth, triangle and variable pulse waveforms. The oscillators can be individually tuned or synced together. Similar quality VCF and VCA sections from the Prophet 5 can be found here too! The P5′s Poly-Mod section has also been passed onto the P600.

The P600 is extremely versatile and easy to use! Its best functions include the onboard arpeggiator, 2-track sequencer and poly-modulation. The P600 is great for creating analog effects, swells and drones. It has a cool glide effect and has very flexible modulation possibilities.” Link

up1 “Selling my beloved Sequential Circuits Pro One to free up room in my studio. The synth has been recently tuned by a reputable technician. Due to the nature of vintage instruments, the synth is sold as-is, no returns accepted.

Issues:
1. This unit features the membrane keyboard (this is not a J-Wire model). These keyboards all trigger pretty unreliably, so I recommend you play the synth via CV/Gate.
2. The key bushings need to be replaced. I have a new set I will include with the synth (pretty simple procedure to replace them). Doesn’t make a difference if you’re playing over CV/Gate due to the issues with the membrane keyboard, however.
3. Tuning is a bit flat when playing via CV (but tracks correctly across the full range). Not really a problem per se, just adjust the osc tuning accordingly.” Link

mt “SEQUENTIAL MULTI-TRAK POLYPHONIC ANALOG SYNTHESIZER WITH VELOCITY SENSITIVE KEYBOARD AND ON-BOARD SEQUENCER

The synth works and appears to be perfectly usable, but have few known minor issues:

1) Needs a battery replacement (or any created sounds will disappear after it turned off).
2) Pitch bend probably doesn’t work as I was unable to hear any effect, however it works when controlled by another keyboard via MIDI.
3) Comes without power supply (I tested with my own power supply which is not for sale here).

I was able to program and store few own sounds, but lost them due to issue 1. Selling it as is, for repair.”

Has two minor issues with it as you can see in the invoice worth of over $900 worth of work done on it. The number two on the key pad is not working at the moment so any program with a two in it will not come up. All the other programs plays fine. It also comes with a gator gig bag that it fits in.

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.”
