Oberheim OB-X8 features

New sounds at your fingertips
The OB series factory sounds are there, but new sounds created by world-renowned designers are added, giving you endless possibilities. The OB-X8 features simple controls to create and save your own sounds with ease.

Three synths in one
The OB-X8 combines the architectures of the OB-X, OB-Xa and OB-8, faithfully reproducing the characteristics of each. You can mix elements from these models to create unique, never-before-seen sounds.
Explore new possibilities with OB-X8
The OB-X8 doesn't just reproduce the past: it reinvents it. With the new 2022 Page 2, you have access to over 40 additional controls, including functions such as per-voice panning, additional SEM filter modes and much more. This instrument is designed for musicians seeking new sonic explorations.
