Oberheim Matrix 1000

“Oberheim Matrix 1000 Synth. Vintage Analog. Works great, everything works as it should.

Also some tiny dot stickers on the select, bank, and enter buttons I was not able to peel off (from previous owner). ” Click here to visit listing on eBay

“This Matrix 1000 has been fully pro-serviced unlike most and working great. We paid our tech to perform a necessary power supply modification that most other sellers don’t do, cleaned the potentiometer, and replaced the internal battery, which most sellers also don’t do. This item is being sold by professional perfectionists and will be packed to withstand rough handling. You get what you pay for.” Click here to visit listing on eBay

Oberheim Matrix 1000 Project Machine

“Please read for complete description of the synthesizer.For sale is an Oberheim Matrix 1000 analog synthesizer. I purchased this unit about 5 years ago from a college music professor. It was fully working when purchased and has sat unused for years. I recently powered it on to test it before listing it for sale and it displayed the “1.1.1/6.1.1” error message on the screen. I powered it off and on, and it then worked perfectly fine. All of the buttons work perfectly, all of the inputs and outputs work, the volume knob works perfectly, and it sounds absolutely AMAZING. I left it powered off for a week and went back to it. I powered it on and got the “1.1.1” message, I powered it off and back on, and once again was able to get everything to work perfectly fine. Looking into this error, it looks like an issue with the back-up battery. I don’t have the time or money to spend repairing it so I’m looking to sell it “as-is”, though I’m sure its an easy fix for someone who is familiar with vintage gear. I meticulously package everything I sell and ship ASAP. Because this is a “For parts or not working” listing, I will not accept returns on this item.” Click here to visit listing on eBay

“Oberheim Matrix 1000. Condition is “Used”.

I have owned this unit since it was new, and it has remained in my smoke free, temperature controlled studio ever since.

Everything functions as it should and it is fully operational. I am meticulous with my gear, and this piece is an example of that.

There are a few very small scuffs of the top from rack removal, but otherwise it’s perfect. Cleanest one available. ” Click here to visit listing on eBay

Oberheim Matrix 1000

“Oberheim Matrix 1000 6 voice polyphonic analog synthesiser.

Visually a bit tatty, the faceplate is slightly misshapen and has some rack rash and a few other small marks. The volume pot is also a little bit loose but functional.

1 of the voice chips has failed and needs replacing. I have been using the synthesiser without much problems without it as not many of the 800 presets use all the voices, but you do notice it occasionally. I purchased a new CEM 3396 narrowbody to do this but never got around to it, same story with the firmware update. Both of these are very easy pull out/push in jobs, but while it’s opened up probably worth switching out the battery for a battery holder/button battery (requires some basic soldering), although seems to be fine.

Once you get the new firmware in you have a couple of options for ‘real-time’ control. One of them is an £800-ish controller from Steroping, Another is patchbase which is around 30 quid and works on your computer or iPad.

Comes with the original instruction manual which I have forgotten to photograph but will add tomorrow.”

Oberheim Matrix 1000

“Oberheim matrix 1000 module hardly used just sat in the studio never on the road. The internal battery was replaced and that erases the first 200 presets. All the other 800 presets are in ROM and intact. The first 200 are in RAM that means that can be rewritten and they are only copies from that other 800 presets anyway. They are easily recopied from the manual by pushing a few buttons. The sounds are very fat. ” Click here to search for synths on eBay

“The original analogue rack-mount synth module is on offer here. It works great, just tested several of the ONE THOUSAND PATCHES myself and it sounds amazing. This unit is a 120V original, made in the USA from Oberheim. It features lots and lots and lots of sounds from the Oberheim Matrix 6R and a ton of other sounds. It has MIDI in, out, and thru, a single 1/4 output. LED display is bright (pictured). There is some rack rash around the rack ears, on the top and bottom (pictured). Buttons are all responsive and all functions seem to work. Comes only with a power cord, but you can find the manual online. Can’t go wrong with this one. They are getting kinda rare, too, so grab this one up today!” Click here to search for synths on eBay
