“Oberheim Matrix 6 midi synth keyboard with rare extras.

Superb condition for a 30+ year old analogue synth, one of the classic sounds from the 80s – all Oberheim synths sound HUGE! Awesome thick strings, cutting bass lines, anything the Matrix 6r or 1000 can do this does with a keyboard attached, and with 2 cool levers running both positive & negative. Assign these in the mod matrix.

I believe that last OS chip was retro fitted, and it has a 3 month old battery upgrade installed using the CR watch type batteries – easy for you to change next time! I loaded a sysex dump off of the web of nice sounds, plus this package includes the original manual, original brand foot pedal plus rare cassette tapes – Oberheim volume 4 150 basses, and the factory preset volume 1.

Oh, and a hybrid case too!” 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

“Oberheim MATRIX-6 Analog Synthesizer. Classic analog synth from the 1980s.

Never left my home studio. Been in a Calzone case in a corner all this time and recently took it back out, plugged it in and still sounds great. Ran through all the keys and programs, worked perfectly. Excellent keyboard with aftertouch, great as master controller. Hate to part with it and all its fond memories but I don’t have the time anymore.” Click here to search for synths on eBay

Both look good, Matrix has some rack rash on rack ears, but works perfectly. this is just by far the best oberheim for the money. Classic rich pads, strings, brass, basses, leads all for a low price considering how much OB8, OBXA, Xpanders are selling for nowadays. ” Click here to search for synths on eBay
