Sequential Circuits Prelude

by

” Sequential Circuits Prelude up for sale. It’s in good shape cosmetically except for a few missing switch/slider covers. Everything on it works, but some pots and switches are sputtery, and the LFO section pots are a little unpredictable. The instrument does produce a clean sound that corresponds to the switch/slider settings after you’ve wiggled the switches/sliders. The keyboard feels like a typical vintage keyboard that has not had any work done. All the keys work. Some cleaning and servicing would help this instrument.” Click here to visit listing on eBay

Sequential Circuits Drumtraks

by

“SCI DrumTraks in excellent working condition, recently serviced, and updated to work at 240v. Cosmetic condition is VG++.
Unique/desirable features:
– 12 bit crunchy sounds.
– Pitch the sounds up or down – they will sound different to doing this with a sample in your DAW, due to the unique circuitry, similar to the LM-1.
– It is possible to change the single-chip voices to DMX or Linn Drum ones.
– It swings like an LM-1 due to the 24PPQN MIDI Clock (which it can also output).
– Unique and fierce sounding drums, especially the *clap*, thunderous kick, snare and ride, especially pitched down.” Click here to visit listing on eBay

Sequential Circuits Pro One

by

“Vintage Sequential Circuits Pro-One analog synth. Recently serviced and fully cleaned by Takeshi at Main Drag Music in Brooklyn. Fully working J-Wire keyboard and several upgraded and restored pots, keyboard bushings and wiring. Unit is in AMAZING sonic, mechanical and cosmetic order and we are reluctant to part with it. We have a Prophet 5 so most of our vintage SCI sound is covered, but this unit takes CV and Clock I/O as well as External Audio, which is a big part of the way we work with synths. You can bring anything into this filter and control the filter CV externally!! Can route tons of modular gear through this and it BLOWS AWAY most of the modular. The keys on this unit are a joy to play and rock solid. The arpeggiator works along with, basically, a legato mode on the keys that plays at the same time, and can be set to either transpose or add notes. It is a great feature and there is tons of tweakability on this synth – which makes it very special and why prices are only going up right now. There is one piece of gaffer tape we put over part of the fuse box, as it is inherently a bit flimsy and having it prevents any issues from fuse popping out for any reason. ” Click here to visit listing on eBay

Sequential Circuits Pro One

by

“Sequential Circuits Pro-One, J-wire Keyboard, Recently Refurbished. Condition is “Seller refurbished”.

Had the bushings replaced, j-wire keyboard cleaned up, oscillators tuned and the power cord replaced. Everything else just needed to be cleaned off. The only noticeable damage is a few chips and dents in the wood siding.

I would certainly prefer local pickup as it is decently heavy and I would hate for it to be potentially damaged during shipping.” Click here to visit listing on eBay

Sequential Circuits Prophet 5

by

“Up for sale is an original Sequential Circuits Prophet 5 straight from the Tone House personal recoding studio. This Prophet 5 has been in our studio for years and was the go-to analog synth. Not only are the original sounds extremely flexible, this particular 5 (Rev 3.2) is outfitted with MIDI in/out so using it with modern keyboard controllers and time locking the information out then back into your DAW can be easily done. Cosmetically, the synth is in great overall shape. It exhibits a minor discoloration on the wood panel under the control plate which can easily be seen in the pictures. There are a few other light age marks and the Prophet 5 logo is rubbed away slightly. Overall, the synth is in great condition. Now is your chance to own this legendary synthesizer!” Click here to visit listing on eBay

Sequential Circuits Prophet 600

by

“10/15/20. My tech just went through and check all functions. Battery is good and shows 3V.

This is a rare Sequential Circuits Prophet 600 OS version 2.9 (uploaded Video showing power up can be seen in my tristarmusicgear Instagram page) in 100% working condition with the must-have GliGli Mod, which truly takes the synth to the next level, putting it alongside the Prophet 5 as one of the greatest analog polysynths ever.

The previous owner painted the wood side panels black, which in my opinion gives it a sleeker and more refined look. See for yourself in the photos. If you prefer brown wood, there are a few people selling Prophet 600 wood side panels online. Few dents on the membrane panel.

The synth was fully cleaned and serviced by a synth professional when acquired from previous owner. There are a few small scratches and dings as you can see in the photos, and a few knobs have fading paint, as you might expect from a synth that is almost 40 years old. All buttons, knobs, and switches work as expected (make sure to read the GliGli manual at https://gligli.github.io/p600fw/), and the sound is unbelievable.” Click here to visit listing on eBay

Sequential Circuits Pro One

by

“I am the original owner of this Pro-One. It’s in excellent condition. I had SynHouse MIDI installed in the late 90s. It has The more reliable & preferred 37-note J-wire style keyboard. Recently is was serviced/refurbished by vintage synth repair specialist John Paul Bohon of Double Heart Audio in Austin. You can see more of his work at SwitchedOn vintage synth shop in Austin. The synth and the MIDI work perfectly. The synth comes with its original user’s manual and SynHouse MIDI manual. Also included is a receipt for the recent work done.

The last picture is a picture of the holes above the pitch and mod wheels. In the left hole, just below the surface is a MIDI tuning slot. The right hole is a small button. It resets and changes the MIDI receiving channel. MIDI functionality is explained in the included Synhouse manual. They were installed with the MIDI installation.

The work done recently is listed on the receipt in the pictures. It includes repair MIDI functionality, replace the MIDI jack (I had a cleaner looking jack installed), replace/lubricate all keyboard bushings, repair four non-functioning keys.

Feel free to message me if you have any questions.” Click here to visit listing on eBay

Sequential Circuits Prophet 2002

by

“Zum Verkauf steht ein Sequential Circuits SCI Prophet 2002 Racksampler.

Der Sampler funktioniert zu 100% bis auf den rückseitigen MIDI OUT/THRU Umschalter für die dritte MIDI Buchse. Dieser Schalter ist bei dem Prophet 2000/2002 bekannt für einen Defekt. Wer die Umschaltung braucht kann ihn einfach tauschen.
In dem Sampler wurde mal vor Rund 5 Jahren ein Schaltnetzteil eingebaut (der Originaltrafo ist weithin im Gerät). Dies sorgt für deutlich kühleres Klima im Gerät, und erhöht somit die Lebensdauer. Zudem verbrennt man sich an der Rückseite nicht mehr die Finger am Gehäuse.
Das letzte ROM 4.3b ist verbaut – somit kann wunderbar auch mein Editor mit diesem Prophet eingesetzt werden ( http://synth.curlsystems.de ). Das Diskettenlaufwerk wurde mal von meinem Vorbesitzer getauscht – auch dieses funktioniert zuverlässig.
Die Anleitung ist leider abhanden gekommen, aber im Internet findet sich diese als PDF. Kann ich auch gerne auf CD beilegen.
Der Zustand ist recht gut – es gibt ein paar kleinere Schrammen. Eine ‘größere’ ist auf der Beschriftung des Bedienpannels beim Parameter ‘Sound Number’. Für die Funktion allerdings irrelevant.
Der Sound von dem Gerät ist – wie soll ich sagen – dank der analogen Curtis Filter sehr schön. Es geht von Sanft bis Brachial. Als Speicher sind 512kWord verbaut (also mit einer Erweiterung).”

Sequential Circuits Six-Trak

by

“Sequential Circuits Six-Trak 6 Voice Analog Polyphonic Synthesizer w/ Programmer.

In great condition. Recently serviced by previous owner. Synth works great! Keypad can be a little hard to operate but is to be expected of a keyboard this vintage.

However, you won’t really need the keypad with the addition of the programmer! I will include instructions on how to use. This really unlocks this synth’s potential.

You’ll own one of the greats! This synth’s brother is the Prophet 5. It’s filter sounds unlike anything else. This is a killer synth. Has the warm analog sound that we all go after as synth heads!” Click here to visit listing on eBay

The working condition of this unit is unknown

It has been sitting in a box in my closet untouched for more than 20 years

When last used, it was in good working condition

I have no good way to test the unit
