Oberheim Matrix-6R

“This unit went has been sitting in my studio rack, used very little since 2003. After recently taking it out for testing, here is what I found. The unit powers up just fine. Midi signals are received just fine. Sounds are great. Audio output at the rear 1/4 inch output jacks is only present at the LEFT/MONO jack. Headphone out jack works normally both left and right. No issues with switches. The front panel is in very nice cosmetic condition, but the sides have some surface stratches from being pulled in and out of racks(all pictures are of the actual unit). Made in Japan. USA Only shipping. Unit and power cable only. No manual included.” Click here to visit listing on eBay

Oberheim Matrix 6R

“Undeniable, unbeatable, classic Oberheim sounds! The real-deal analog sound powered by a digital architecture and membrane buttons for programming.

CONDITION: Very, very clean condition for its age (1986) and fully functional with zero issues. Regarding cosmetics of the unit, there is a slight divot on the “4” button along with the typical, slight rack rash along the top rim of the unit that is to be expected from being mounted and unmounted within racks over the years.

NOTE: A custom-machined pair of 3U rack ears WILL BE INCLUDED as part of the sale.” Click here to visit listing on eBay

Oberheim Matrix 6R

“I’m the original owner. Bought it some time in the late 80’s or early 90’s. Used it on various commercials and multi-media projects until around 2004, when I left the biz. It’s been sitting in a rack in my smoke-free, personal studio since then. It hasn’t even been powered up much in the last 17 years. It was in very good cosmetic condition, until I tried to clean the sticky residue from a label off the top left front the other day. That cleaning solution caused the finish to smear and look ugly. I’ve tried to provide several pictures and angles of that discoloration so that you can see it clearly. There’s also a light scratch in the upper right part of the display.
I’ve tested its operations, and it’s working great, midi connections and response are good, and it’s still got that fantastic Oberheim analog synth sound. I reset it to all the factory original presets. I even still have the manual.” Click here to visit listing on eBay

Oberheim Matrix 6R

“This is a 120v unit which has been professionally converted to 240v, but can easily be converted to suit most regions. Will not be supplied with a power lead as it is just a standard kettle cord readily available in every country. Will require a step transformer if using outside a 220-240v region.” Click here to search for synths on eBay

Oberheim Matrix 6R

“I’m the original owner of this Oberheim Matrix 6R analog synthesizer module. Originally released and built in 1986, these rack mounted synths were emblematic of that Oberheim sound – thick, synthesized waveforms. I’ve had this rack mounted in my personal smoke free studio since I purchased it in the late 80s. It’s in excellent condition, with only a few rack rash marks. I recently tested it out, all seems to work well. Software version 2.13.

Although it doesn’t currently need one, I recently bought a back up battery, which I’ll send along for those who know how to change it. I also have the original manual and a cassette that came with it, containing 1000 sounds. There are many other ways to upload sounds via MIDI which can be found online.” Click here to search for synths on eBay

“Oberheim Matrix 6R Polyphonic Analogue Synthesizer, with V2.14 Firmware. Condition is “Used”. Kept in a smoke-free studio, the photos show how well this synthesizer has been cared for.

The V2.14 Firmware provides much better midi response and allows use of the Beautiful and Free CTRLR Matrix 6 editor. This basically allows the 6R to act as a VST, but with all of the authentic analogue goodness. Includes a CD-R with patches and both the VST and stand-alone editors.” Click here to search for synths on eBay

“Oberheim 6R in excellent condition with no issues. Some static in the volume slider but does not carry through to the triggering of sounds. No worries if you patch the module to a mixer and leave the volume slider set. Digital back lights work perfect. No wear on the face.

Oberheim Matrix-6

” Up for sale is my Oberheim Matrix-6. This synth is in great condition. All keys play as they should, velocity and after touch function properly. The membrane keys all work as well as all sliders. I’ve recently cleaned the key bed and contacts to ensure it plays with the expression it was made to. It does have some minor wear and tear, but nothing beyond what you’d expect from an almost 40 year old synth. It also has custom wood side panels to give it a unique look. I really really like this synth a lot, but unfortunately I just don’t play it as much as I used to and I need to make room for some more synths I have my eyes on (so it goes). ” Click here to search for synths on eBay
