Matrix 6

” Classic Oberheim Matrix 6 in full working condition. New battery installed last month as well!

This synth has that unmistakable OB sound at a price that is way more affordable than an OB8, OBXA!

Although you can fully edit any sound and create some wicked lush sounds.. I used a software editor to speed up that process. There are many great editors for Mac, PC and IOS.

This Matrix is in great condition in and out. No issues.”

“Oberheim Matrix 6 Vintage Synthesizer in Very Good Condition. Condition is Used. Shipped with UPS Ground.

Synth is in really good condition. I recently took it to one of Chicago’s best synth repairmen to clean pots and fix any inconsistencies in its performance. It’s in better shape now than it was 20 years ago when I bought it. I have the receipt for the work that was done.” Click here to search for synths on eBay

“For sale is my Oberheim Matrix-6. This synth is in great condition. All keys play as they should, velocity and release velocity, (you can modulate parameters by how quickly you release keys), function properly. The membrane keys all work as well as all sliders. 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 tauntek’s eprom upgrade from version 2.13 to version 2.14 for faster MIDI parameter changes. Version 2.13 is included in a static free bag taped inside the synth. I really really like this synth a lot, but I just don’t play it as much as I used to, and I’m downsizing my studio.

This is a great way to get that famous Oberheim sound without dishing out 5k on an Xpander or OB-8. I’ve owned it for the past several years in my studio (smoke free) and never gigged with it. If you’re not familiar with this synth you can read about it on vintagesynth.com. There are also some great editors for the Matrix-6 online for loading a large assortment of banks and editing parameters.”

“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

“Oberheim Matrix-6 Synthesizer

Original owner, purchased new in 1986 and maintained by owner. Good condition, but hasn’t been played regularly in recent years. Replaced backup memory battery, put new caps in power supply. Checked basic functions, MIDI in/out, external program load, keyboard, front panel settings – all appear to be operational. Passes calibration routine with no errors. Checked DAC and HFO calibration with meter and scope. This synthesizer does have some wear and tear. In the mid 90’s the main board was damaged by an electrical surge which required repairing a trace and replacing the EPROM, micro, and memory. The low C key cracked during a move and was repaired with lexan bracing under the key. The repair is visible but the key is solid. There is a custom port (plugged) next the headphone jack that was used for a custom breath controller board add-on. This board has been removed from the synth. See photos. The synthesizer has not had any problems since. Selling as-is. Keep it going for another 30 years. This package includes:

“What we have here is my old Oberheim Matrix 6 synth that my dad bought me new back in the mid ’80’s. It plays, sounds and looks good for it’s age. There are a couple of scratches and dents here and there. Over the years, I’ve replaced a couple of broken keys but have had no other repair work done. The volume fader can be a bit scratchy and the output jack can sometimes be a little touchy. As far as I can tell, everything else works well. The factory patches are loaded and software version is 2.13. Many other patches are available online for free. I’m still looking for the manual, sustain pedal and additional patch cassettes. If they tune up, I will definitely include them.”

“I have had this matrix 6 for at least 10 years. I don’t really want to sell it, but my car needs the transmission rebuilt and as you may know that is expensive. Something has to go!

If you don’t know anything about the Oberheim Matrix Six, it six has that sweet analog sound that everybody wants, six Oscillators and full midi capability. velocity and pressure sensitive keys. This is an undervalued gem, grab it while they are still affordable.

It has been upgraded to the newest firmware, everything worked great when I put it away. Brought it out to sell and everything still works great as far as I can tell, I can select patches with the keypad, I can play music, and pleasing sounds then come out of my speakers.

Comes with what I believe to be the original foot pedal, a power cable, And the heaviest duty keyboard case I’ve ever seen, it is a tank! Unfortunately the foam is deteriorating, so you’ll have to re-foam it before you can really use it. I will ship the keyboard in the ATA case but will use extra bubble wrap inside to protect it since the foam is falling apart.”

“oberheim matrix 6. Condition is Used. The instrument is in good shape with original patches. There are two minor sound issues – the right output doesn’t work and voice chip 2 is pretty wonky. These should be pretty straight forward repairs. ”

” Hey guys I’m selling my Oberheim Matrix 6 analog synthesizer. It has been used exclusively in smoke free studio environments. Physically is in good working order, but from time to time will have a screen freeze and the unit needs to be turned off and then on, and randomly will not turn on – this may require maintenance in the future so I’m selling it at a reduced price. Other than that the synth sounds great, keyboard is in good condition and cosmetically the synth looks pretty good.”

“Up for auction is my Oberheim Matrix-6 synthesizer. I’ve used this synth in my smoke-free home studio for the past five years, and I know it inside and out. This synth is in immaculate cosmetic condition, and it sounds amazing. The mod matrix really allows for the creation of much more unusual and interesting sounds. All buttons, volume slider, pitchbend levers, jacks, and synth functions work perfectly.

I replaced the internal battery four years ago, so it should be good to go for another six years or so. I have loaded this synth with the factory patches, so the buyer will receive it basically as it would have originally been sold. I’ll be sorry to see it go. It’s a truly inspiring synth, but I’m moving in a different direction.” Click here to search for synths on eBay
