Oberheim OB-Mx

   (0 reviews)

Remember the days when men were men and synthesizers were synthesizers? Knobs, switches, and such stuff were in abundance, imagination could run rampant, sounds were unabashedly electronic.

These days our musical lives center around four button interfaces, canned sounds, cryptic displays, and tedious instruction manuals. Interaction isjust a fond memory, and the concept of actually playing a responsive electronic instrument seems to have died along with Flash Gordon.

Problem back then was that while you could get into pretty deep space, you could never get back to where you'd been yesterday—synths, with their infinite possibilities, were conspicuously short on memory.

So we had this crazy idea. What if we took the sounds of the 70's, the technology of today, combined them with controls up the wazoo, and an accessible user interface? Could be interesting.

Welcome to the OB Mx.
