The Oberheim OB-Xa was Oberheim's overhaul of their first compact synthesizer, the OB-X. The OB-Xa was released in 1980, a year after the OB-X was released. Instead of point-to-point wire circuits, the OB-Xa and the Oberheim synths to follows use Curtis integrated circuits. This made the inside of the synth less cluttered, and cause less hassle to replace bad parts. Aside from better hardware than the OB-X, the OB-Xa had better interface features. These included being able to split the keyboard into two manuals of different voices; the ability to double-up voices to create wider sound (essentially making two notes sound for every key pressed); and a better array of polyphony for even the base models.
[edit] Trivia
This synthesizer was the compositional center of the Van Halen song, Jump.
