obie1000 “This is an Oberheim Matrix 1000 pre Gibson era rackmount synth module. 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! ”

obi10000 “For sale is my Oberheim Matrix 1000 rack unit. It’s in great shape, it does show some wear, so be sure to check out the pictures below to make sure you like it. Overall nice condition. 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. Don’t miss out!”

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

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.”

obie-1000 ” Oberheim Matrix 1000 analog synth for sale, in near-mint condition! I am only the second owner of this synth, the first owner had it in storage since the late 80′s and never played it. It is cosmetically and functionally in great shape. Very minor rack rash from screws.

I have upgraded the firmware to 1.16, which allows for much quicker real-time editing of the synthesis parameters, and a great sounding unison detune feature that gives the Matrix a more drifting, VCO-like quality. This new firmware allows you to tweak the filter cutoff and other important parameters with editor software without the synth crashing and freezing, as it did with the original firmware. Amazing synth for electronic music, ambient, or techno. Gets that vintage Vangelis / Boards of Canada / Tycho sound easily.

Manual and power cord included.” Link

The cosmetic condition of the unit is good, some scratches due to rack use. If you’re planning on installing it in a rack anyway they won’t be visible for the most part.

It is in excellent condition, and looks like it just came out of the box. I do not know very much about this unit, however if you are reading this description I will assume that you know what this is. I do not have the equipment to fully test it, however it powers on and the numbers change when the different buttons are changed. I will attempt to test it further is you message me and tell me how. This unit is ready to be rack mounted. If it doesn’t work fully I will refund you the full purchase cost including shipping. Power cord is in great condition and is approximately 9 feet long. ” Link

Note on condition: If you look closely at the main photo, you can see the cosmetic flaw on the left end of the front panel: The end of the panel got bent, and a slight wrinkle now exists in the front panel where the bend was straightened out. It’s purely cosmetic, and the unit is 100% fine in every other regard. Under most lighting conditions, the flaw is harder to see than in the photo, and not something most people would notice if they didn’t already know it was there.” Link

Cosmetically, the ears/screw holes are a little worn out from years of rack mounting and moving around but seriously not bad and not bent at all. See photos.
