The OB-8 was the last of the classic OB series that included the OB-1, OB-Xa and OB-X. The OB-8 is a very warm and rich sounding eight voice polyphonic synthesizer with that classic Oberheim sound. Because it was released just before MIDI debuted, the OB-8 had no MIDI implementation originally, but some models were retrofitted with 9-channel MIDI implementation. The OB-8 did use Oberheim’s very own digital buss system making the OB-8 the center-piece of your OB-studio, allowing it to connect to the DSX polyphonic sequencer, DMX drum machine and other OB-synths. In a time before MIDI, this type of instrument connectivity was truly awesome !! € 2500 !!
