“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.” Link

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. Also the synth’s firmware has been upgraded to Bob Greib’s 1.20 version which fixes many original bugs. ” Link

obiemxatr ” Up for sale is my one owner Oberheim Matrix 1000 synth module. I purchased this unit brand new in 1990. This unit is in perfect working order, and has only been used in my smoke-free home studio. The exterior exhibits the usual minor rack rash, along with minor scratches in the paint on the top panel. It has no significant dents or dings, and has never been dropped or otherwise subjected to any impacts. All six voices are fully functional, and just calibrated by myself. This unit has been upgraded to firmware v1.16 as shown in the photos. This fixes numerous bugs that existed in the factory ROM, most notably slow filter response via MIDI cc’s. Because of the firmware upgrade, the filters on this unit respond almost instantly. I used this as a wind synth module, and since the upgrade has been installed, the response to aftertouch and breath is exceptionally fast. If you’re an analog fan, you can’t go wrong with this unit. It contains 800 factory sounds, and has 200 user slots to store your favorites, or your own custom patches created with an external editor. Included with this unit is the power cable, the original owner’s manual and patch listing, and a manual on programming the Matrix 6/6R/1000. Don’t let this one pass you by! ”

It’s fully functional and sounds great. Screen is bright and easy to read. The volume knob is a little loose but functions as it should. Awesome vintage analog oberheim sound, the same as a Matrix 6 but in a 1U rack format. There are many different programmers out there available for this, which really can enhance its usability.

oberheimamtrxi1000 ” I am the original owner of this Oberheim Matrix-1000. I bought two of these back in the day and this one mostly sat in the original box (I used the other one). This is the rarer, cream colored face that Oberheim sold late in the production run. It’s in amazing cosmetic condition considering it’s age and the only flaw I can find is a tiny dark mark on the right side of the unit on top of the cream faceplate between the screw and rack holes (see the 4th photo). This synth is over 20 years old and it’s very unlikely you can find another in this condition.

It includes the box, power cord, the original laminated patch list from Oberheim and the original manual. The cover of the manual has yellowed a little bit with age. The box is in excellent condition and includes the original styrofoam inserts and will be double boxed for shipping.” Link

It is in good condition, and was given a given a once over by EMS Services last year (see pics) who fixed a crackling volume pot, and gave it a clean bill of health….It does hum when it is turned off (always has), but apparently this is common with these units. Case has a few small knocks and scratches commensurate with it’s age, please check photos.” Link

It’s definitely used, ears are a bit bent, scratched on top from racking. But functionally everything works great.

*Edit: Added the photo with the level by the front, since my phone apparently has pretty bad lens distortion that makes the front look bent and caved in in the top down picture. It’s not the prettiest piece but it’s not totally bent out of shape!” Link

Matrix 1000, Oberheim @ 20 December 2016, Comments Off on Oberheim Matrix 1000

obiematrix1000 “Manufactured in March 1989, this Oberheim Matrix-1000 single-space analog rackmount synthesizer module packs the same six-voice sound engine as Oberheim’s Matrix-6 keyboard synthesizer. It’s loaded with 1,000 beefy matrix-6 patches — 200 for user patches — and you can load additional Matrix-6 patches using system-exclusive MIDI data or a software editor/librarian.

Each of the Matrix-1000’s six voices sports two DCOs (digitally controlled analog oscillators), a lowpass filter, two VCAs, three envelope generators, two LFOs, and two ramp generators. This module works great, is in reasonable cosmetic condition, and has always been used and stored in an entirely smoke-free environment. Turning its volume knob can induce crackling into the audio signal, but the noise disappears when the knob is left alone. As you can see from the close-up photos, there’s a bit of wear and tear on the front panel, but the rack ears are straight and all of the buttons and the display work perfectly well.”

If you’re looking for one of these I don’t need to put in much description. I’ll put some in below but you should look up reviews on line. Just know that this has served me well over the years. There are some scratches but it works great. You can’t buy these types of sounds any more. It was mainly used in my studio and I’ve moved to a computer based system due to size so the racks have to go.

It has great pads, strings, bass, and lead sounds. ” Link
