Oberheim OB-1

“Up for sale is perhaps Oberheim’s most undersung but amazing sounding monosynth. The OB-1 does not sound like a SEM, and it does not sound like one of their later polys–it has it’s own distinct sound and power that rivals any other monosynth from that era. Take the girth of an Octave Cat A-Rev. and apply some Oberheim filter flavor and you have an idea of what this sounds like.

This OB-1 is the first, and rarer, MKI version that has the very fast discrete envelopes (the later versions were grey like the OB-X and used a CEM 3310 envelope chip). It has both MIDI and the Tauntek CPU update that allows real-time editing of all parameters on saved patched, and an increased preset memory (using RAM instead of batteries). It has also been fully serviced by Bell Tone Synthworks here in Philadelphia and is ready to rock for the foreseeable future.” Click here to visit listing on eBay

Oberheim OB-1 Project Machine

“Purchased in 2002. Very clean condition. There is no pulse wave on VCO 2. It came that way when I bought it, so I just leave it on Triangle which sounds just great. The manual says you can vary the slope of the Triangle waves, but I have never been able to do that. You can vary the pulse wave on VCO 1. Everything else works great. Two sub oscillators to create a really fat sound, plus cross mod and sync to get some very interesting sonic explorations. These synths are quite rare and not up for sale very often. They are direct descendants of Oberheim’s SEM modules. A true piece of synthesizer history.” Click here to visit listing on eBay

“Good Condition and recently gone through by a local tech who also installed the a new

Tauntek programmer with the following updates:

A new MCU-based programmer pcb is now available for the OB-1

I have designed a replacement for the Oberheim programmer with the following features:

1) 64 programs in 8 banks of 8

2) Programs are stored in non-volatile EEPROM. No battery needed.

3) After a program is loaded, only controls that have moved are “live”, so patch editing is now possible.

4) Manual mode forces all controls to be “live”.

5) Optional (non-volatile setting) periodic flash of current bank selection

6) Optional (non-volatile setting) quantization of coarse freq for oscillator 1 to octaves

7) Comes with 24 pre-programmed patches, which can be over-written later if you chose

8) Smaller pcb mounts on four of the existing standoffs, providing better access to pcb underneath

9) Implemented connectors are the same as original programmer for easy installation

10) All IC’s are socketed. All components are through-hole.

11) 20-turn trimpot for easier one-time oscillator tuning adjustment

More info at tauntek OB1 site

I installed new key bushings as well in the last month.

Outer case has some blemishes and surface rust here and there, but in overall good cosmetic condition.

Pretty rare piece and would make a great addition to your studio or collection.” Click here to visit listing on eBay

Oberheim Matrix 1000

“I have too many synths so I have to make room! This guy is amazing! The sounds that come out of this are SUPER musical! Its a true analog synth which has analog oscillators which are controlled digitally. Very advanced for its time. This unit has a reputation and it deserves it. It is monotimbral and polyphonic. It can play 6 notes max simultaneously. You wont need that many notes to create powerful sounds! For the best programming experience, if you want to program your own unique synth voices, I highly recommend midiquest pro. I havent found any other editors that work as good as that one. Its available online. But as the name states, it has 1000 sounds already onboard, so just browsing through all those, you should be able to find something very close to the sound you want and then modify it to your liking. It sounds so beautiful… It has midi in/out/thru, Mono 1/4″ Out, and the power cord is included. The rack ear on the right is slightly bent as you can see in the picture but it doesnt affect the functioning in any way.” Click here to visit listing on eBay

obie-1” Bought this in 2003. Excellent condition. Used in my home studio only-temp controlled, no smoke. Have a lot of synths that I don’t play much, so time to pare down and keep only my most used ones.
Everything works perfectly, including the memory, EXCEPT…
The only problem is the OSC 1 Pulse setting doesn’t work. There is one knob to choose between Saw on the left and Pulse on the right.
No go on the right. It came this way when I bought it. Seller didn’t disclose this fact, and I didn’t make an issue of it (maybe should have). It doesn’t really affect anything in the overall scheme of the sound design. With OSC 1 on Saw, you still get that analog Oberheim sound that’s quite distinctive.
I’ve always loved the big sound and versatility of the OB. I also have a Moog Voyager, so that will be handling alot of the sounds the OB can do, but of course, it’s not an Oberheim.” Click here to visit listing on eBay

ob1 “As is no returns no exchanges no refunds. Vintage electronics needs cleaning,restoration and calibration. Not fully working. VCO 1 FUND & VCO 2 FUND & OCT do not appear to make a sound. Noise and VCO 1 OCT appear to function and all other controls have an effect on the sound. All keys sound but will need cleaning. No battery is in the unit and i am unsure if the PROGRAM section will store/retrieve your 8 personal presets.” Link
