With the OB-Xa, its users can enjoy classic Oberheim sound, which sounds fat and wide as usual. That’s because the OB-Xa offers up to 8-voice polyphony, which surpassed the 5 voices of the Prophet 5. The Oberheim sound sounds so familiar nowadays because many well-known artists have used the synth and its factory presets in their songs. Most notably Van Halen, who used an OB-Xa riff in their song Jump, which became insanely iconic for the time.
