“100% working. Normal scratches and scuffs, but no major damage. I think the LED window was once loose and is taped to face plate from inside. Original 1.11 firmware. Likely original battery that will need eventual replacing. I have owned this synth module since the late 90’s and it’s always been stored in climate controlled smoke free environment…and used very little during my ownership.” Click here to visit listing on eBay

“An Oberheim Matrix 1000 rackmount analog MIDI synthesizer, with US-IEC power cable, original owner’s manual, and a box from Synthesis Technology with two new-old-stock CEM 3396 voice chips (as used by the Oberheim Matrix 1000). I bought this unit back in the late 1990s and then purchased the new CEM 3396 chips around 2003.” Click here to visit listing on eBay

“This is the great Oberheim Matrix 1000, with 1000 pure analog patches. This synth packs so many sounds, it can be overwhelming. I’m also pairing it with an Alesis Qudraverb. The two together are perfect for most synth needs. The Obi works great but the volume pot is a little scratchy, I used it mainly with my Keystep for a year or so, and only in my house. From what I was told it is all original and no mods or updates have been done. Not sure if Ive gone through every patch, but the ones Ive used sounded amazing. Quadraveb is in decent shape, Ive noticed that if you move it around alot the output can cut off, but is not really an issue for studio usage.” Click here to visit listing on eBay

“Up for bids is one vintage OBERHEIM MATRIX 1000 rack-mountable analog polyphonic synthesizer. This is a used item in good cosmetic condition overall, with just a bit of rack rash on the bottom of the synth. There are a few scratches, but no major gouges or dents. It is in fully working condition; all 6 voices are operating. The display, buttons and volume knob are all functioning. Audio out and midi (in,out & thru) are operational. A new battery clip and battery have been installed. All factory patches and rom patches are reinitialized. There is a slight hum from the power section, but it is only audible in close proximity to the module, and is not part of the audio output, and has never caused any issues with either the sound or operation of the synth.”

“Important! This is a Japanese Import but I will include the step down transformer for it.

It sounds great. I love the Oberheim sound and this has the classic patches. I was thinking about upgrading the rom to open up the programming but never got round to it and I’ve now got other gear that is easier to program and overlaps with what this does.

Please see the photo – the right side rack ears have been bent at some stage so it can’t be racked with all four screws in place.

I used to have it near the top with 3 screws securing it”

“Vintage Oberheim Matrix 1000 Synth Module

Recently serviced. The following work was performed:

Battery Socket installed with new battery

New ver 1.20 firmware (designed by Bob Grieb) installed

DAC Calibration

Factory Calibration

Factory sounds restored

The battery clip will make it simple to maintain as opposed to the soldered in type battery’s which require complete disassembly and soldering to replace.

The new firmware supersedes the v1.13 which fixes the MIDI controllable parameter bugs in the original factory firmware. It also supersedes the v1.16 (by Gligli) which still has some issues and was never really finished according to the author. Bob Grieb’s v1.20 provides all of the improvements of 1.13 and 1.16 and new improvements for parameter control via MIDI. It includes his MIDI parameter speed-ups plus Gligli’s de-tune code. He also added code to display the values of the parameters as they are changed via MIDI and also the detune value. The code writes directly to the display and doesn’t tell the M1K to write over it so it holds the display of the value until the next Note On or similar message is received which will cause the display to revert back to its normal contents. It also fixed the NRPN “inc” and “dec” commands which are still broke in v1.6. ”

“The classic Oberheim sound in one rack unit, absolute bliss. I’m only selling to upgrade to an Xpander. This Matrix 1000 works perfectly and is in great shape.

Please keep in mind that like many Matrix 1000’s, this unit has a hum from the power supply. It is barely noticeable when it’s mounted in a rack but when you power it up on a wooden table (like I just did to take pictures) you definitely hear it. There are solutions to this available online, but it never bothered me enough to warrant them.” Click here to visit listing on eBay

Unit is fully functional, the battery socket has been upgraded and battery replaced, all six voices have been tested and calibrated and are in full working order. There is some minor cosmetic damage owing to its age and some of the front panel buttons stick, but all of them work. I am including the original owners manual which is more of a reference guide. I am also including a spare CEM 3396 voice chip. This is the most commonly replaced part on these synths and are increasingly difficult to find.
