Oberheim OB-X8 Keyboard – 8-Voice Polyphonic Analog Synthesizer

The Oberheim OB-X8 Keyboard is a flagship 8-voice polyphonic analog synthesizer that faithfully recreates the legendary sound of the iconic OB-X, OB-Xa, and OB-8 in a single instrument. Designed by Tom Oberheim, the OB-X8 combines the unmistakable warmth, depth, and richness of classic Oberheim synthesizers with modern reliability and performance features. Featuring a 61-key FATAR keyboard with velocity and channel aftertouch, a true 100% analog signal path, and an intuitive knob-per-function interface, it delivers an inspiring hands-on experience for professional musicians, producers, composers, and sound designers.

Powered by two discrete SEM/OB-X-lineage voltage-controlled oscillators (VCOs) per voice, the OB-X8 offers authentic SEM and Curtis filter architectures, allowing players to switch between the distinctive sonic characteristics of the classic Oberheim models. Modern enhancements such as bi-timbral Split and Double modes, Vintage control, programmable stereo panning, enhanced Unison, and a full-featured arpeggiator make it equally at home in the studio and on stage. The latest OS 2.0 also introduces MIDI Polyphonic Expression (MPE) support, 32-voice Poly Chain, expanded memory, and new filter and modulation options for even greater creative flexibility.
