Oberheim OB-X8 Synthesizer Goes Far Beyond The Capabilities Of Its Iconic Predecessors

Ahead of Superbooth 2022, photos and specifications have leaked for the Oberheim OB-X8 synthesizer.

The Oberheim OB-X8 is a new synth design, in the same family as classic synths like the OB-X, OB-Xa and OB-8. It’s an 8-voice analog design, with discrete SEM/OB-X VCOs, Curtis filters and envelopes based on the originals. It offers 400-plus factory programs, including the full set of factory sounds for the OB-X, OB-SX, OB-Xa, and OB-8.

But the OB-X8 also goes far beyond the capabilities of its iconic predecessors, featuring new filter options, the ability to dial in ‘Vintage’ variability, velocity sensitivity and aftertouch, new synthesis and modulation options and more.
