“For sale by original owner, purchased 1986, serial #02241. Exterior condition: excellent; never left my studio – but diskette drive needs replaced (“Lh” locked head error msg, will not read disks). (There have been replacement drives on the market – also USB-based floppy emulators from companies like HxC and N-Drive that specifically support the Prophet 2000, but I have no experience with those.)

61-key velocity-sensitive keyboard (no aftertouch)
12-bit sampling at 42K, 32K, or 16K
512K sample memory (two banks of 256K)
8-voice polyphony
Great-sounding analog VCFs (with resonance) and VCAs
Samples can be mapped into 8 layers across keyboard
Loads samples via internal 3.5” diskette drive (or MIDI Sample Dump Standard, SDS, if you can find appropriate software)
Built-in arpeggiator
MIDI In/Out/Thru

Original footpedal & approximately 100 sample diskettes (3.5”) included. (Can’t guarantee that 100% of them will read, given their age and because I can’t load them with its current floppy drive – however, approximately 35 backup copies—smaller boxes in the photo—are also included.)

Spring for pitch-bend was replaced.

No original manual, but PDF copies are easily available online.” Click here to visit listing on eBay

“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

” You will not be disappointed from the big rich tones that this unassuming synth puts out. One of the original predecessors to the Dave Smith prophet, this synth has 100 presets that give off that quintessential 80’s sound with looks to boot. From funky to spooky this synth will definitely make you think of soundtrack to stranger things. it has a built sequencer that features 6 banks you can store or stack tracks in. I can’t even begin to describe how BIG of a sound it has, it gives my Roland Juno 60 a run for its money. Minor scuffs and scratches that would be common for a synth of its age. (see photos)” Click here to visit listing on eBay

“This Six Trak is in very good condition and working perfectly. All controls have great feel and respond accurately. All lights fully functional. All ports and jacks in great shape and connect without issue. Sound is strong and clear. Keys straight and play nicely. Some scuffs and dings on the wood end panels and general signs of age, but overall in very good physical condition. ” Click here to visit listing on eBay

Some extremely light rust on the left hand side. Does not affect playback.” Click here to visit listing on eBay

Pro One, Sequential Circuits @ 18 October 2018, Comments Off on Sequential Circuits Pro One

“Up for sale is a highly modded and amazingly cool Sequential Circuits Pro One.

This synth is modded. Keyboard is an entirely rebuilt J wire keyed… not the horrible membrane version. The serial of this synth lands in the membrane keybed version but a J wire keyed was overhauled and installed. It plays and tracks extremely well. No double triggers or mis-triggers. It also has an aftertouch strip put in. The key dip is just a tiny little bit less, and there is a pic showing that. The keys goes down a little more when you activate the aftertouch. Very light and quick action. The aftertouch controls many things. Pitch up and down, modulation, LFO, Filter, etc…Very flexible variations. Also there are two pots inside the synth for gain functions for the aftertouch if needed. There is an additional LFO pot added , and there is duel portamento pots for the two VCO’s . Very effective on glides rather than the stock single portamento . Also a momentary jack in the back for on/ off portamento. Again a very effective performance feature. Tested , and everything works as should. In tune and calibrated. Ground loop issue corrected, which was common for these keyboards. Condition is good. There are a few marks on plastic and some marks on the keys. But its all minor… jut=st stating for full discloure on this ad. The only thing to note is that the Master Tune pot shaft has the tip broken off. You can still easily use / adjust it. With all the mods completed, this takes the Pro One to a whole new level. Ive created some very wicked efx, basses, leads that simply cant be done on a regular pro one. GREAT synth, great condition, great price. ” Click here to visit listing on eBay

“This unit is used, but it is fully functional and has been recently serviced, has new battery for the memories which will provide years of trouble-free service. The power supply capacitors have also been replaced to ensure quiet operation.

I’m selling this unit as is – it is a used instrument, but has been well cared for in my home studio.The side wood panels have a few character scratches and dings as seen in the photos. The unit otherwise is spotless with all knobs, buttons, keys and pitch and glide wheels trouble-free.

The unit is also shipped with USB flash drive with many documents, factory patches, schematics etc included.

It has an upgrade EEROM OSv14 installed which allows for program changes via knob. Also shipped with the unit is the original working factory ROM chip” Click here to visit listing on eBay

“A nice condition Prophet 600 with the Gligli mod. This synth is sooo warm compared to modern synths. Just had it tuned up by The sequential guy here in the Bay Area. The Gligli mod changes up a few of the functions some of the knobs do so make sure to download the Gligli manual to know what your twisting. As with all vintage analog synths, let her warm up for at least 5 minutes to let the oscillators tune. It’s with a heavy heart that I sell this wonderful machine.. ”

“Sequential Circuits Pro One Analog Monophonic Synthesizer Fatar Keybed Turbo CPU MIDI

I’m selling my beautiful Pro One.

I’ve modified it with the Turbo CPU Midi Upgrade and I’ve installed a new Fatar keybed so you don’t have to worry about failing membranes or adjusting j-wires.

With the new keybed it plays and feels like a brand new modern synth.

It’s the same keybed that is installed on most modern Moog synthesizers.

The connections are identical to the Moog Little Phatty keybed.

The midi upgrade is a nice improvement.” Click here to visit listing on eBay
