Oberheim's description of the Oberheim OB-X8 analog polyphonic synthesizer
For the first time in more than 40 years, a legendary analog synth sound returns
True Oberheim Sound
It sounds like a classic Oberheim because it is a classic Oberheim. Its 100% analog audio path cuts through a mix like no other synth.
The classic OB-series factory sounds that you know from countless recordings are all here. But that’s just the start: our network of world-class sound designers has created jaw-dropping new sounds just for the OB-X8. And because the 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
The OB-X8 combines the three different voice architectures of the 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 neverp ossible with the originals. There's never been an OB-series synth as powerful and versatile.
A Classic — Evolved
The OB-X8 is more than just a new OB-series Oberheim. It’s engineered to be the best modern OB ever created.
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.
OB insiders know that the myriad of “Page 2″ functions unlocked the hidden power of the original OB-X, OB-Xa, and OB-8. We've 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, the 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.
