Ensoniq VFX SD Project Machine

“”Problem:

1. No sound coming out of the phone and other outputs

2. The battery needs to be changed

3. MIDI Channels need to be checked to see if it’s working properly

Action: Verified no sound out of any outputs. Replaced (1) 3V battery. Resoldered the power supply and the contact bridge of the keybed communication boards. Resoldered multiple capacitors and connectors. Performed hard reset. Attempted to reload some tracks from the library via MIDI, but the motherboard did not accept the communication. The motherboard or the keybed scanner could be damaged. Could not find schematics or tech support. Need another unit to compare against to solve cost effectively. The customer decided not to continue with the repair.”” Click here to visit listing on eBay

Oberheim Matrix 1000

“An underrated analog synthesizer. 1000 presets of Oberheim goodness. Upgraded the OS to 1.20 for better midi functionality. This synth functions 100%. Does have some rack rash and the rack ears are slightly bent. Also ever since I’ve owned this synth it’s only had 1 screw holding the body together this makes the select button sunk in a little bit. If all the screws were there it would look normal. This does not effect functionality. Selling to fund some new gear.” Click here to visit listing on eBay

Oberheim Matrix 1000

“This module has been in a rack since it was first purchased in 1989. It belonged to my relative who was a sound engineer/producer that worked in Roger Troutman studios in Dayton. I took it and placed it in my rack. It has served me well, which I used with my MPC2000, and more recently my MPC One. The sounds are amazing, but I am going away from retro(80’s-90’s) production. Power cord and manual will be included.”

Oberheim Matrix 1000

“I bought this Matrix 1000 and a Matrix 6r over 9 years. They both worked perfectly fine with all the presets and sounds working great. I plugged both of them back 2 years ago and noticed that they were no longer working as well as before, losing their original power and now both are barely getting a signal. I talked to a local synth repairman and he told me to change the battery and firmware. I honestly never got around to servicing these machines, so I am letting them go for a very fair price. This (Matrix 1000) comes with the power cord and a new firmware chip as shown in the pictures.” Click here to visit listing on eBay

Oberheim Matrix 6R

“I have for sale my Oberheim Matrix 6R Rack Mount Polyphonic Synth Serial #KGB4919 from the original owner.
This product was purchased in the US and will ship from our studios in CT.
 
Considering how old these are I would put this in the “excellent” category, however it does have the usual amount of scratches on the top and bottom from other rack gear being installed and removed. There are some minor scuffs and specs on the front but please check the photos to 1) see if you can notice them and 2) make note if they bother you. 
Otherwise, it works perfectly. I recently sold my mint condition OB-XA so I have a good handle on Oberheim products, so feel free to ask any specific questions or you can download the manuals from various sites as well.”

Oberheim OB-1

“Oberheim OB-1 in great working condition.
All keys are working well with even action. The output is full range and low noise as designed. The programmable presets all work, reliably, writes, and switches cleanly with LED tally indicators. Envelope generators are good and sharp. Both volumes good. Bend lever good, portamento good. Keyboard Track good and nice to have. Every mode works. To my knowledge, this has not been serviced or repaired. Note: the rear AC power switch lamp is out. Also notice the pitch bend lever bushing is missing its dust cover. All collet knobs and caps are good and not brittle. All pots are smooth and quiet. All 2 and 3 position slider switches are also of high quality and working cleanly in all modes. All black caps are programmable, grey caps are not.
This is a very nice sounding, comprehensive analog monophonic synth with two oscillators.”

Oberheim Prommer

“We bought this in the 80’s to create some cool samples to trigger. Midi was really basic then and so were samplers. This is a classic piece of vintage gear. Apparently you can burn chips to put into other samplers. Been sat in the studio as a bit of an ornament for years. Awesome wooden sides. It probably belongs in a synth museum or needs to go to an avid collector of cool retro kit” Click here to visit listing on eBay

Oberheim Matrix 6

“Selling an Oberheim Matrix 6 in fantastic condition. All keys and their velocity responses work very nicely, all membrane buttons work, most with a single press and a few with occasion harder presses, and all 6 voices work and sound excellent. Aftertouch response is usually weak on this model synth, but mostly works on this unit except for the upper range. Keybed itself feels great and expressive to play. The classic Oberheim pitch and mod levers work great and snap nicely back to center. And cosmetically it’s one of the nicer examples I’ve seen, with only minimal wear that’s hard to notice from this very slick looking vintage 1985-1988 beauty. Overall it looks really clean and it sounds amazing. This was the “poor man’s” Oberheim to get access to the legendary Oberheim sound from the more expensive higher end models such as the OBX, OB8, and OBXA via a knobless, minimal, and digital interface. It also introduced an incredibly deep modulation matrix (hence the name) for unprecedented sound design capabilities.

Operating system is updated to the latest factory version 2.13, and I will also include a Tauntek v2.15 firmware chip (an additional $50 value) for you to easily and optionally install. Will package professionally and carefully with thorough bubble wrapping to ensure safe arrival.”

Oberheim Matrix 1000

” Vintage Oberheim Matrix 1000 Analogue Synthesizer. Great Sounds!. Perfect condition except for light scratches on the top from being in a rack.. I am the original owner. It lived in the rack in my home studio exclusively which I took down in the late 1990’s. It has just sat in the rack unused since then. I held on to it (and other gear that I will be selling in the near future) in hopes of restarting my studio. I can see now that that is not going to happen and so here it is. It really wasn’t used very much at all. It has great sounds and I hope someone can put it to good use. Comes with the original box and manual. Happy bidding!”

Oberheim OB12 Project Machine


I have for auction a rare OBERHEIM OB12. Passed on to me by a friend who has moved overseas. It has not been used for quite some time and has been in storage.

In overall good cosmetic condition, and most importantly – it powers up and works.

However it is not without issues….

As you will see from the photographs it has a broken key (bottom B), although the key does still trigger. I would suspect a fragment of the key has dropped inside as you can hear something rattle when the keyboard is moved.

Also the neighbouring key (C sharp) occasionally doesn’t trigger if hit gently (sometimes it’s ok) – therefore I suspect a dirty contact.

I gather these particular Oberheim’s have an inherent problem with the backlight not working on the display – and this model is no exception. Other than that the display shows all information, it’s just not bright.

Also on the filter section the ‘KBD TRACK’ knob has snapped off, so will require a new potentiometer and knob.

Aside from that the keyboard seems to work fine and I’ve had a good play with it. As a virtual analogue synth bearing the Oberheim name it is capable of some pretty beefy and unusual sounds. I’ve had experience with analogue synthesisers in the past and am fairly familiar with their workings, however this is the first time I’ve used an Oberheim and some of the controls I am not familiar with. I’ve messed around with all the different sections and their related controls – oscillator’s, filters, envelopes, effects etc etc and all seems fine. The only function I can’t seem to get to work is the arpeggiator, however it could just be me not fully understanding it?”
