DX, Oberheim @ 11 April 2017, Comments Off on Oberheim DX with Mods

dx ” Oberheim DX 1982 Drum Machine. Functional and sounds terrific. Includes all sound chips. Powers on and was cleaned out a few years ago when I rescued it from my friend’s shed. There may be some dust but no where near the decade of dirt that was there when I found it. After cleaning it powered up and I’ve been jaming with the live functions from time to time.

Haven’t ever programed any sequences (mainly because I don’t know how to) but it plays sequences programed by the past owner. Most of the switches work but not all. However you can trigger the sounds by making a connection on the underside of the circuit board so they most likely need re-soldering on the reverse side I assume. The volume sliders don’t seem to work too well but since each channel has it’s own output for studio recording, individual volume control would be a sinch when hooked up to an external mixer. Missing two slider knobs as pictured.

Fun vintage drum machine that has a legendary pedigree. New Order – Blue Monday is probably my fav but if you are looking at this I’m sure you’ve done your research.” Link

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

dx “For sale is my Oberheim DX which is in great shape.
As on every DX out there, the battery which drives the memory is dead and needs replacing. A new battery can be had for $12.
This never bothered me as I just make new beats each time I use it.
Besides the battery, there are two tiny issues with it, neither of which affect play-ability, and are as as follows:
The Bass and Snare sliders are a bit sticky. They both function fine with no noise, but require a little effort to get them to slide.
The bottom Crash button and the middle Shaker button sometimes double trigger when you hit them.
Again, neither of these issues affect the units functionality, and are extremely minor considering the age of the instrument
Physically, the unit is in great shape. The cheeks are wood and have some wear on them, which I tried to depict in the photos.
These things were built like tanks and have stood the test of time.
The inside is very clean and it doesn’t look like anything has been tampered with.
I have loved this DX dearly, but it is time to let it go.” Link

Matrix 1000, Oberheim @ 14 March 2017, Comments Off on Oberheim Matrix 1000

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! ”

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.

I just completed a major overhaul of the keyboard in which all the contacts were cleaned and bushings replaced. No sticky notes. The previous (original owner) had an aftermarket midi kit installed that has basic in/out/thru functionality and is solid. I’ve had zero problems with this throughout the years it’s been in my possession and has had regular maintenance service.” Link

It includes the original owner’s manual, service manual and power cable. I am also including a clear plastic dust cover custom made for the Xpander.

I am the original owner.

The digital displays shown in the pictures are actually clear. For some technical reason, the camera setting made them look foggy. I believe it is because they are fluorescent.” Link

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

OB-X, Oberheim @ 07 February 2017, Comments Off on Oberheim OB-X Project Machine

obx ” I’m relisting my OB-X. For those who were watching it: I had it listed last week, but after a couple of days, I got cold feet about selling it and had retracted the listing early as I wanted to sleep over it some more in order to decide whether I really want to sell it or not and needed to come to terms that if I sell it, chances are slim to none of me ever owning an OB-X again. However, after careful thought, I’ve decided to sell it after all..(sniff). So, here it goes again:

This 8-voice OB-X powers up, but outputs only weird and static sounds and seems to freeze up on default sound upon power-up.

I purchased this OB-X last October, basically as a non-working unit, i.e. it was only outputting a ground hum type sound. I had it serviced just over a month ago in mid-December by a local tech in San Diego, CA in order to “bring it back to life” and paid $842 for it (see image of invoice). The tech identified and repaired a short, which apparently was due to corrosion from mouse urine, recapped the power supply, rebuilt/recapped the voice cards and swapped their trimmers out with the multi-turn kind, installed new key bushings and then fully calibrated it. When I picked it up from the tech, it worked. But only about 3 short days later, the synth started to freeze up, only seconds after powering it up and became stuck on the default sound, meaning it was non-responsive to any further preset key selections or attempts to edit it. When I contacted the tech 3 days later to report what was happening and to ask if he could take another look at it, he told me over the phone that this must be a new issue and likely not related to the work he’d already done on it and needed to open another ticket for it, thus incurring further repair costs. Unfortunately, I don’t have the time, money, and energy to keep this going and decided to sell it as-is. ” Link

When I first got the unit, some of the data pots didn’t increment each time the pot clicked, but after some use they all work now. I haven’t used any of the CV outs. I don’t see why they wouldn’t work since everything else does. The unit comes with original manual and 3 backup cassettes.” Link
