“Sequential Circuits Model 1005 Poly Sequencer

for the Prophet 5 Synthesizer

(Connects to the Prophet-5

Through the Digital Interface Jack on the Back of the Synthesizer)

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

However, since I do not have a Prophet-5 anymore,

I have no good way to test the unit

The unit does power up (the record button flashes after powering up)

As a result of not being able to fully test the unit,

it is being sold “for parts or not working”” Click here to visit listing on eBay

“This unit was originally owned by composer Jim Johnson of the WWE. This sampler was used in Jim’s studio for years making it onto many of his recordings. The Sequential Circuits Prophet 2002 is fully functional and in very good condition overall.” Click here to visit listing on eBay

“1x Sequential Circuits Pro One Vintage Synthesiser

In good working order, just had a service

Rebushed j-wire keyboard, plays nice and keys are level

Couple small chips on the front panel which are purely cosmetic

Missing both name badges, which it has been since I got it.

All time classic mono synth from sequential circuits. essentially a single voice prophet – and too wonderful for any words to do it justice! It also is the model with a Tibetan Buddha and chant* stencilled on the circuit board, for extra good vibrations!” Click here to visit listing on eBay

“Up for auction is my Sequential Pro One vintage analog synth w/MIDI in near mint condition. It has the more desirable j-wire keybed which has been painstakingly refurbished.

What has been done:

MIDI kit installed. Simply connect a MIDI cable from your controller or sequencer to the MIDI IN jack. Hold the red button down to enter MIDI mode. Send the kit a MIDI note and it will respond on that channel from that point forward. A red LED above the pitch/mod wheels indicates whether or not it is receiving MIDI. CV/GATE can also be used.
Keyboard bushings replaced, bushings greased, j-wires polished, every key removed/cleaned/polished, and keybed painstakingly adjusted to perfection (both height and width). Each j-wire adjusted so that they hit the buss wire at the same time for more accurate keyboard response. Keyboard now plays like butter. I have extensive experience refurbishing pratt-reed keybeds and took extra care to make this synth play like a dream. This easily took 4-5 hours of painstaking work to complete.
Prophet-5 knobs with metal caps installed. Paint on caps is absolutely perfect, with no scratches.
Every knob removed and cleaned with a toothbrush to get all the dirt out of the cracks.
Wood panels removed, sanded, waxed, and hand-rubbed to bring out the grain.
Pitch/Mod wheel plastic replaced with NOS wheels from Wine Country. The old ones crack over time and can slip on the pots.
All pots and switches cleaned.
Power cord replaced with a much nicer panel mounted 3 prong IEC power receptacle. Makes it much easier to remove from a stand (power cable included).
Inside and outside of synth completely cleaned.
Synth voices calibrated and checked over for tuning stability up and down the keyboard.

I own two Pro-One’s, and this one sounds the best of the two. It stays in tune up and down the keyboard. Pots have been cleaned but a few might be scratchy. I will retest before shipping. Not sure why this one has such a nice rounded, thick character to it but I prefer the sound over my other Pro One. Physical condition is very clean, near mint. The wood panels have some nicks and dents here and there, and small holes where knots are in the wood. Every knob cap is pristine. Every knob has been cleaned. A few scratches on the front panel. See photos for details. Only selling to fund another purchase. I am very picky about my gear, and have refurbished this to as close to perfect condition as possible.” Click here to visit listing on eBay

Sequential Circuits, Six-Trak @ 07 March 2019, Comments Off on Sequential Circuits Six-Trak

“Amazing multi-timbal polyphonic analogue synth built in 1984 by Sequential Circuits, with MIDI, on board sequencer, arpeggiator and monophonic unison mode for nice thick sounds. If you’re looking at this listing you probably already know what it can do, but check out this post http://www.vintagesynth.com/sci/stk.php or have a look on YouTube for videos of it in action.

Bought it from my friend a few years back as it needed some TLC and he wasn’t using it, so took it to Synth Prof (synthprof.com) for a full MOT and UK mains conversion, which cost £225 around 2 years ago (if you need specific details of the work that was done I can email Andrew at Synth Prof for more info).

Some minor marks on the wooden end panels but nothing more than you would expect from a machine of this age. Otherwise has been looked after well and not used very often in a smoke free studio.”

Prophet 2002, Sequential Circuits @ 28 February 2019, Comments Off on Sequential Circuits Prophet 2002

“Good shape, everything works, some physical wear is evident. There is some rust around the holes for the rack screws and a few minor scrapes in the finish. There is also some residue on the bottom, where there may have been rubber feet? The pictures give a good indication.

I just today tested loading and playing sounds, as well as all the buttons and knobs. All controls and lights are functional. The disk drive has been replaced years ago, and it does work. The new drive is smaller than the original, so there is a gap between the drive and the control surface of the sampler. This is shown in the pictures. ” Click here to visit listing on eBay

Pro One, Sequential Circuits @ 21 February 2019, Comments Off on Sequential Circuits Pro One

“I’m selling this much loved piece of kit as it’s been under a dust sheet in my studio for the last 12 years and deserves some use. It’s been well looked after but hasn’t been used for some time. It’s never been gigged – studio use only. Before listing I fired it up for testing and it could do with a service but a spray of pot cleaner in the right places would probably do the job.

Supplied with the original manual in pristine condition!
The Pro Solo is a little bonus to help get to hooked up and started with the Pro One straight away.” Click here to visit listing on eBay

“PHYSICAL CONDITION: Good – There is a 4″ strip of wood missing from the top part of the right side panel. There are light scratches and scuffs all along the sides of this synth. All the LEDs light up as they should. All the pots rotate nicely. The master volume pot/knob wiggles slightly from side to side compared to the other knobs. All the push button feel good and the I/O jacks on the back are solid. The keybed’s fast, light action feels great and the keys are level with each other. All the keys are fully intact with no major chips or cracks to speak of except for the Bb/A# key to the left of the middle C which has an extremely small blemish near the middle. The power cord is in great shape with no tears to speak of. Overall, this synthesizer is in good physical condition WORKING CONDITION: Excellent – Works like a champ! All keys, all control knobs, all buttons, all LEDs, both pitch and mod wheel as well as all I/O are working perfectly! Overall working condition is excellent” Click here to visit listing on eBay

MAX, Sequential Circuits @ 07 February 2019, Comments Off on Sequential Circuits MAX

“This Synth has been modified with the addition of the following features:

• 100 sounds, all downloadable, located in battery-backed RAM

• Note storage increased from about 500 to about 3200

• Unison mode added.

• Three sets of 100 factory sounds in EPROM: 80 Max + 20 Six track Unison factory sounds, 100 Six Track factory sounds, and 100 Multi-Trak factory sounds (without chorus or velocity sensitivity, of course)

• CC parameter changes to current program can be saved to program 99, then copied to any other program

• MIDI receive buffer increased from 64 bytes to 128 bytes

• Removed code that reduced volume of subsequent notes if CC change received while MIDI note with low velocity playing. This a code bug in the original EPROM.

These features were added by upgrading both the EPROM and the type/amount of RAM. The Max shipped with a 128K EPROM and two 2Kx8 SRAM chips. This modified Max has a 256K EPROM and a single 32Kx8 SRAM chip (only 16K is used). The modification is a small PC board which holds the EPROM and NV SRAM. This board plugs into the existing EPROM socket on the Max. Five additional wires connect from the Max main board to the new memory board. In addition, the two SRAM chips on the Max main board have been disabled. See more info by googling “Sequential Circuits MAX Mod Page – Tauntek”

INCLUDES:
-Synth
-Manual
-Power Adapter

ABOUT THE SEQUENTIAL CIRCUITS MAX:

The original NON-Modded Sequential Circuits Max was designed as a companion to the Six-Track, Multi-Trak and possibly the C64 personal computer. It relied on MIDI messages for parameter changes, having no on-board way to vary them. It came with 80 “factory sounds” in EPROM, and storage for 20 more in RAM, which could be used after downloading via MIDI. Two “songs” or sequences could be recorded and either stored in RAM or dumped to MIDI. No battery back-up was provided for RAM, so all song data and the 20 programs were lost when the unit was powered down.

Synth is in great working condition. Guaranteed to be operational. Returns accepted if Synth is not working as described.
