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.
