Oberheim OB-X

Programmable analog polyphonic synthesizer

The Oberheim OB-X, released in 1979, was Oberheim's first fully integrated programmable polyphonic synthesizer, available in four-, six-, or eight-voice configurations. It replaced the earlier stacked-SEM approach with internal discrete voice boards and patch memory, with two VCOs per voice and a discrete low-pass filter, and a 61-note keyboard.

    Synthesizer · United States

    The Oberheim OB-X series is the line of integrated, programmable analog polyphonic synthesizers that defined the Oberheim sound from 1979 onward. Beginning with the OB-X and continuing through the OB-Xa and OB-8, the series replaced the earlier stacked-SEM voice cards with internal voice boards and patch memory. The modern OB-X8 revives the line, combining the OB-X, OB-Xa, and OB-8 voice architectures in one instrument.
