Oberheim OB-1

   (0 reviews)

The Oberheim OB-1 was a monophonic, programmable, analog synthesizer introduced by Oberheim Electronics in 1978. It originally sold for $1,895 and was the first analog synthesizer capable of storing patches.The design was based on the Oberheim SEM (Synthesizer Expansion Module) and intended to be used for live performance.

The OB-1 was essentially an all-in-one, pre-routed Oberheim SEM and had one voice of polyphony, with two VCOs and a switchable multimode filter. It also contained an envelope control for both the filter and amplitude.
