About the original OB-Xa:

The OB-Xa is an iconic analog synthesizer produced by Oberheim from 1980 to 1982.
It is famous for its rich timbres, used by many renowned artists like Van Halen, Prince, and Jean-Michel Jarre. The OB-Xa has 2 oscillators per voice, allowing polyphony of 4, 6 or 8 voices, depending on the configuration. Its resonant low-pass filter and ADSR envelopes contribute to its distinctive sonic character. Because of its short production period, the OB-Xa is a sought-after instrument for its unique sonic qualities and lasting impact on electronic and pop music.
