– analoger Synthesizer Klassiker –
– einer der vielseitigsten Mono-Synths überhaupt –

Der Pro One ist in sehr gutem Zustand!

Top Zustand! neueste Revision (mit J-Wire Kontakten) Die Tastatur spielt sich gut! Das ist eher eine Seltenheit, da die meisten älteren Revisionen schlechtere Tastaturen haben!

Er liefert dicken Soud (Bass, Leads und Seq.&more), der in so einer Form auf digitalem Wege nicht nachzuemulieren ist. Ein Urgestein elektronischer Musik, dass an Liebhabern gewinnt! Extremer Seltenheitswert und Preissteigerung. Dieses Exemplar liefert eien besonders eigenen Klang. ”

“Selling my beloved Sequential Circuits Drumtraks.
few of the buttons that trigger the sounds sometimes getting stuck and triggering the sound more that one time wehn pressed.
I never fixed that since it didnt bother me because I was triggering the drums through MPC or other sequencers and then everything working smoothly.

Included with the drum you are getting 5 extra eproms (sounds) that you can replace + manual” Click here to visit listing on eBay

“I’m very sad to see this one go, but I need the space in my tiny studio. I’ve only owned it for a year and it has not left my studio. Previous owner was a well known keyboard/vintage gear shop.

I’ve gone through all the keys and knobs. Everything works great. Certain numbers on number pad can get stuck occasionally but after tapping once or twice they go back to working fine. The output sounds great, and the midi works. Sequencer and arp are working too! ” Click here to visit listing on eBay

“Works great, just have to make sure to use the high output jack or else you can’t really hear it. While some synths have low and high outputs they usually aren’t very different from one another. This one really has a low output if you use the low output jack, they weren’t kidding around when they labeled it. I have no idea what the input jack is for, I’ve never used it and I don’t use pedals with my synths so I’ve never tested the footswitch jack or the volume pedal (this has a strange jack for the volume pedal. Looks similar to the output jacks you find on Soviet made guitars and basses). It’s got some wear on it that’s visible in the photos, but that’s to be expected with a 30+ year old instrument. Some of the switches are slightly bent as you can see in the pictures, a couple of the switch tips are missing, and it sounds like some of them could use some compressed air, but they all function perfectly well.

It’s output only goes to one channel, it sends a mono signal (it’s a polyphonic synthesizer though) so you can’t use headphones with this one. You’re going to have to play it through an amp.” Click here to visit listing on eBay

Sequential Circuits, Six-Trak @ 23 August 2018, Comments Off on Sequential Circuits Six Trak

” 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

Pro One, Sequential Circuits @ 23 August 2018, Comments Off on Sequential Circuits Pro One

” The synth has been taken apart, refurbished and cleaned. Some old electrolytic/tantalum capacitors has been replaced and a busted IC-chip as well so now the machine is good as new again.

A true classic analog synthesizer. 110V unit so you might need a step down transformer in countries with different current. Comes with owners manual and well boxed.” Click here to visit listing on eBay

MultiTrak, Sequential Circuits @ 26 July 2018, Comments Off on Sequential Circuits Multi-Trak

“The fine item you are considering is a Rare Vintage Sequential Circuits Multi-Trak Synthesizer Model 615 Keyboard No Power Supply. This cool vintage keyboard is being cold “as is” as I do not have a power supply and have no way to test it. My understanding is that these usually have an internal battery which will also need to be changed. The unit came out of long storage, and was quite dusty, but I cleaned it up pretty well, although the pitch bending wheel is still a bit grindy from dust. Cosmetically, the unit makes a nice overall impression, although one corner does show chipping/banging (see photos). Since I have no way to test this rather rare keyboard, I’m selling it “as is” at a low price that reflects that fact. Please see my photos to have a look at this nice item.” Click here to visit listing on eBay
