Oberheim OB-Mx Sample

Title link takes you to an amazing sample of the Oberheim OB-Mx sent my way via Brian Kehew of The Moog Cookbook. I've heard some samples of the OB-Mx in the past that were good, but nothing like this. There is a bit of controversy over the OB-Mx. Don Buchla helped design the synth. There was an early prototype version said to sound much better than the final release. It's rumored that the final release was rushed to market by Gibson (owner of Oberheim at the time). The synth was buggy, voice boards were prone to failure and tuning problems, it was very expensive, and it was said that it was lackluster in the sound department. After listening to these samples, I'm not so sure. It sounds amazing to me - very unique, heavy and full. This thing has balls. Big stinky, rubber, balls (something rubbery about the sound). Put a plug in it Butt Probe, this is refined nastiness.

Thanks for the sample Brian. Here are a few older posts on the OB-Mx: 1, 2, 3 (samples), 4 (pics and samples), 5 (samples).


  1. has a 6 voice OB-Mx up for sale in their "used gear" section.

    Shame about the bugginess though.

  2. :-|

    My old Casio "$49 special" toy keyboard sounds like it had more fidelity.


  3. John Duval may still be selling his.

    It is a nice synth. Has original character.

  4. You're a funny man synthbaron. I should have put that up to keep the prices falling. : )
