Oberheim OB-Mx

The OB-Mx is an analog sound module from 1994. Our OB-Mx has one card which means it can be used in two ways: two monotibral voices or 2 monophonic voice parts. There are two filter modes, 12 dB/oct which sound like Oberheim filters and 24dB/oct which sound like Minimoog filters. So there are two oscillators, 4 multistage envelopes, 3 LFO's, and 4 filters.

It was designed by Don Bucla, Lynx Crowe, and Richard Bugg, all of whom worked on it at various stages of development after Gibson purchased Oberheim, so Tom Oberheim was not involved. There is a long, rough story about it’s development here. Gibson had used sub standard components that were not up to Don Bucla’s specifications, however these components have been professional replaced in our particular unit with upgraded components that stabilize the tuning, filter, and more.

It is capable of some pretty space sounds. It was used as the bass sound on Nine Inch Nail’s track “The Becoming.” Trent Reznor said about the OB-Mx prototype that it is the “…greatist-sounding keyboard in the world, because it sounds like a Minimoog and an Oberheim, and you can run each one through each other.” It has also been used by Deep Forest and Sneaker Pimps.
