obie-matrix-6 “Up for sale is this Oberheim Matrix 6!
I bought this keyboard around 5 years ago from the original owner and it is in great condition which can be seen in the pictures. I’m selling this because I don’t use it far enough and it’s a really cool synth that I’m sure someone would really enjoy.
It all works fine and is factory original.” Link

The membrane panel is in good shape. Expect some scratches and wear across the entire instrument, but nothing serious. Certainly acceptable for its age. Great sounding and powerful.” Link

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. ” Link

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!!!!” Link

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.” Link

obi-6 “Zum Verkauf steht ein OBERHEIM MATRIX-6.

Über den Matrix-6 muß man nichts erzählen, jeder Synthesizerliebhaber kennt die klassischen Synthesizer von Oberheim.
Dieser M6 hat schon bessere Zeiten gesehen, daher Verkauf als Ersatzteilspender.
Der Netztrafo fehlt, die tiefe C-Taste ist abgebrochen.
Das Gehäuse und die Tasten selbst sind in gutem Zustand.

Ich habe das Voice-Board vor einiger Zeit in einen funktionierenden Matrix 6 eingebaut und es funktioniert, alle CEM3396 sind selbstverständlich vorhanden.
Über die Funktionalität des Prozessor-Boards und der Netzteilplatine kann ich keine Aussage treffen.

Es ist sehr gut möglich, daß ein Bastler durch den Einbau eines neuen Netztrafos den Synthesizer wieder zum Leben erwecken kann, ich selbst hatte nie die Zeit dazu. Das ist aber nur etwas für einen erfahrenen Elektroniker, daher ausdrücklich: Dieser Synthesizer ist ein defektes Gerät als Esatzteilspender. Wer eine Reparatur versucht tut dies ausdrücklich auf eigene Gefahr!” Link

When operating, everything works as expected and all voices respond correctly. Includes original Oberheim footswitch and original printed manual, as well as standard power cord. I’m a classical player, so this board was never abused. (Original owner) I had the final firmware revision (viewable on chip if you open it up) done sometime ago, so it’s the best they come. Display is bright and perfect, but please remember the power supply will need replacement by a qualified tech. ” Link

matrix6 ” For sale is my Oberheim Matrix 6. It’s in good shape. The right end cheek is a bit damaged (came that way when I bought it) and the top most key is broken. The key should be cheap and easy to find, if I have some time I’ll try to source one and replace it myself. Otherwise it looks great and is fully functional. Runs at 230v so in the USA you’ll need to use a step up transformer with it ($20 on amazon or local electronics store). If you are in Europe it should work perfect for you. The Matrix 6 has great sounds, an awesome vintage synth. Don’t miss out!” Link

matrxi56 “This is a used Oberheim Matrix 6 sold by the original owner.

This unit provides 6 voices of polyphony with each having a pair of DCOs, a low pass filter, 2 VCA’s, 3 envelope generators, 2 LFO’s, and 2 ramp gens for a variety of complex analog pads, basses and sounds.

This works as works as expected. There is some very slight filter noise on some of the patches when not played. There are some superficial scratches in the finish.

This listing also includes the original box which is pretty wore out but was been included.” Link

**All keys, display, levers, button functions and outputs work well. There seems to be an issue, though. Only in certain sounds/modes, some lower keys won’t sound when played simultaneously with upper keys. Not sure if there is an issue or that’s how this synth works.

Kind of complicating operation, so the manual should be downloaded and studied.

Midi, Cassette and Pedal 1/4″ out/ins still not tested**” Link

matrix_6 “QUICK ADDENDUM: The keyboard box I had lined up to ship this in fell through, I will need to locate another one. This may add a day or two to the shipping time. I’ll try my hardest to have one by the time the auction ends!

This is an Oberheim Matrix 6 in AMAZING physical condition. The notoriously fragile front panel has a single ding (present when I purchased it originally) that I have highlighted in a supplied picture. The keyboard’s action is unbelievably smooth, the display pristine, and the case itself smooth and almost completely unmarked. I lucked into this unit years ago and ended up barely ever using it due to the complexity of programming it from the front panel. (These days you can get any one of a dozen free patch editors for almost every audio production app on the market.)

There is ONE IMPORTANT THING TO NOTE about the sound of this Matrix 6:

Two of the VCF chips either need their contacts cleaned or simply to be reseated. The net effect is extremely slight, but I want to be as detailed as possible in my description of this instrument. If you play keys on the unit at a normal speed it’s almost unnoticeable, but if you go very slowly and very softly you will hear a small amount of “grit” in the sound of two particular voices. (The dirt is very obviously on the pin(s) that drive velocity against the filter’s ADSR envelope.) I purchased this keyboard years ago knowing this, and the effect has never bothered me enough to compel me to crack open a keyboard this nice looking.

Having said all of that, you will either NOT notice this 99% of the time OR it will drive you completely batty. (I have noticed however that the people it tends to truly irritate tend to be the kind of synth owners ready and skilled enough to perform the 5 minute cleaning and reseating job. I personally do not trust my skills that far with a synth in this great of shape.)” Link

Fully passes Calibration and Tuning tests (see photo’s)

All features work and the case fits it like a glove.

No noticed issues inside, (see photo’s) power supply etc. all look good.

A few minor paint scrapes and there are three cosmetic dings that I mention because that is what I would want if I were buying it (see photo’s)

One “gash” on the label board (does not effect anything just looks).
Two keys, one white, one black were hit by a cigarette and that put a dent in them (they function perfectly and the dent is not where you play.
And one key has a very small chip on the end.” Link

obi matrix 6“oberheim matrix 6 polyphonic analog synth – classic 80s poly synth. the series from oberheim sounds h-u-g-e.

note : the synth fires up correctly & you can see the screen’s display is working fine. all buttons work. all internal cables & boards included as per the pictures. when you play the keyboard the dots on the display show that the 6 voices are firing off one-by-one, and if you play a 6 note chord then all dots light up. no sound is heard from the main or stereo outputs. bad output volume slider? also some of the keys don’t trigger midi data – this means that the keyboard itself probably needs a good clean. it is nearly 30 years old though so no surprise there. also missing a few screws. thats why we have hardware stores!

so, your chance to get a super keyboard at a great price!!! being sold as-is as it is not 100% functional at time of purchase. i will not be held responsible for your ability to fix the unit so, again, sold as-is. ” Link
