Overview
The Oberheim OB-8 is an eight-voice polyphonic analog synthesizer released by Oberheim Electronics in 1983 as the production successor to the OB-Xa. Each voice carries two oscillators with sync, a discrete two- or four-pole low-pass filter, two envelopes, an LFO, and split and double keyboard modes. The 61-note keyboard supports velocity and the unit shipped with MIDI as standard, which the OB-Xa had only added late in its run. It is widely considered the last of the original Oberheim “OB” line before the company’s mid-1980s difficulties.
Origin & History
Tom Oberheim’s company built its reputation on the Two-Voice and Four-Voice modular polysynths of the late 1970s and the OB-X line that followed. The OB-8 streamlined manufacturing, lowered cost, and added MIDI to broaden appeal. Production ran until 1985, when Oberheim refocused on the digital Matrix-12 and Matrix-6 instruments. The original company filed for bankruptcy in 1985, after which the Oberheim name passed through several owners before Tom Oberheim returned to using it himself in the 2020s.
How It’s Played
The performer plays from the full-size keyboard, with the option of splitting it into two zones with different patches or stacking patches across the entire range. Edits are made from the dedicated front-panel knobs and switches; patches are stored internally and recalled by number. Many players relied on the unison detune mode for very thick lead and bass sounds.
Cultural Significance
The OB-8 is associated with the layered analogue pads and brass sounds of mid-1980s pop, film, and rock production. Its tone sits clearly within the Oberheim family alongside the OB-Xa and the earlier OB-X.
