“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.”
