“Used Oberheim Matrix 6 keyboard with the following included: power cord, foot pedal, manual, sound patches cassette, some midi cables and travel case. The unit will be shipped in the travel case along with all of the mentioned items in the case front pocket.

I tested the unit and all buttons are in working order. All output jacks are working. All keys (black and white) are working. Both shifters are working. Volume control is working. Did not get to test the MIDI jacks.

Due to the age of the keyboard, I must disclose the following items.

•The display is not working properly. I did some research and I believe that a battery may need replacing.

•Minimal body scuffs but there is one dent in the corner top of the keyboard. Does not effect the play of the keyboard.

•And finally, the foot pedal does not work properly. Not sure if it is the pedal or the jack. It may be a setting on the keyboard that controls the foot pedal but with the display not working properly, I could not figure it out. The foot pedal is sold as.”

“We got this out of a storage unit. Not fully tested, but turns on and sounds work.

***The bottom 5 keys stick when pressed down. The bottom C key is stuck down. I did not try to force it up. All of the keys work, even the ones that stick. Only the bottom C key is not tested. Also, there is something rattling around inside.

Comes with manual and power cord.”

“**This unit has one flaw…the “Right” output is currently not functioning. I’ve easily overcome that by using the headphone output when stereo mojo is required. However, usually I employ the rock-solid “Left (Mono)” output and run the signal through FX units, so this issue has not impaired my use or enjoyment of this synth. I have priced this unit accordingly, this could be your chance to join the Analog Brotherhood at a great price!

All other functions do work as expected – the membrane buttons are not finicky, the voice chips all fire, the keys are fantastic (one of the better keybeds for this period, IMO), cosmetically very very clean, as the photos attest.” Click here to visit listing on eBay

obie matrix 6
This is my Matrix 6 which I’ve had for 20 or so years. It’s in good shape, having only had studio use in my ownership. There has been some paint scratched from the panel below the keys by the back of a swivel chair some time back when used in a small space, but that’s about the worst of it.
It’s a versatile six voice synth with huge potential for modulation routings thanks to the Oberheim “modulation matrix” which was featured in the synths of the same name. You can route just about anything to anything else quite frankly. The keyboard is velocity and also aftertouch sensitive so allows for some quite expressive playing when called upon.
There are two DCOs per voice with the remaining audio path being analogue. The envelopes are digitally generated but there’s no stepping in the feel of them even when slow. It’s great for pads and strings as well as far out crazy modular effects too. There are a number of editors for these and even with the data entry, programming is not too tricky, especially as there’s a handy crib sheet on the panel.
I used this in conjunction with a Matrix6R rack but now I’m running out of space for keyboards so concentrating on the racks plus a few controllers, hence finally letting go of this one. ” Click here to visit listing on eBay

oberheim matirx 6 “This synth is in excellent condition. Fully serviced by Switched On Austin last year (can provide receipt), brand new battery was put in here in LA by the famed Rob Rosen tech to Iron Maiden amongst other bands.

The Matrix is pure 80’s glory. You want new wave. You’ve found it. Synth Drift all you want! It’s coming out of Studio Big Bang in Hollywood and was recently used by Ikey Owens before his death (Mars Volta, Jack White). Last used on the upcoming Love Athletics album. There is a program you can download to fully control the Matrix in your DAW. Look up Matrix editor on synthtopia. It’s awesome!!!!” Click here to visit listing on eBay

used matrix 6 ” Oberheim Matrix 6 synth in near mint condition. No button issues. Was very well maintained.
Comes with power cord (3 prong).
Only issue I’ve found is that you have to let it warm up about 10-15 minutes. When cold, the volume will increase sometimes and then drop back. Stops once it is warm. Warm up required not uncommon in older analog synths.” Click here to visit listing on eBay
