Pure analog
The audio signal path of OB-X8 is all analog, filled with warmth and punch. It's the same trademark Oberheim sound that made iconic tracks like '1999' by Prince, 'Jump' by Van Halen and 'Tom Sawyer' by Rush so unforgettable, and now it's yours to enhance your own music.
Old sounds and new sounds
The classic OB-series factory sounds that you know from countless recordings are all here, but that's just the start: Oberheim's network of world-class sound designers has created jaw-dropping new sounds just for OB-X8. And because OB-X8 has a clear and easy-to-grasp set of controls, creating your own sounds is as easy as turning a few knobs and saving what you like.
Three in one
OB-X8 combines the three different voice architectures of OB-X, OB-Xa and OB-8 into a single instrument. The individual filter types and other unique characteristics of each model have been faithfully reproduced, giving you the most authentic OB experience possible. You can even mix elements of different models to create sounds never possible with the originals. There's never been an OB-series synth as powerful and versatile.
Meticulously matched
Creating the classic OB sound required more than just replicating vintage oscillators, filters and envelopes. The Oberheim design team exhaustively analyzed and recreated the complex interactions between the various components of each OB-series synth to capture their nuances and character. The result is the most faithful, authoritative renewal of an analog classic possible — with all of the warmth, subtlety and presence of the originals.
Page 2022
OB insiders know about the myriad 'Page 2' functions that unlocked the hidden power of the original OB-8. For OB-X8, Oberheim has included all of the classic Page 2 parameters and created new ones for 2022, giving you direct access to 40+ nuanced controls such as additional SEM filter modes, per-voice panning, LFO keyboard tracking, mod delay time and envelope inversion, independent pulse width control and much more.
A tactile triumph
The unique design of the expression levers was integral to bringing out performances that made the OB-series synths famous. And for even greater expressiveness than the originals, OB-X8 features a premium-quality Fatar keyboard with velocity and aftertouch sensitivity. Dig in with both hands for sizzling filter sweeps, intense vibrato and more.
