OB-6 Operation Manual
Getting Started
Getting Started
The OB-6 is a six-voice, polyphonic analog synthesizer with voltage-
controlled oscillators, filters, and amplifiers. It was designed to provide
all of the warmth, punch, and presence of a classic, SEM-based Tom
Oberheim synthesizer, with the added convenience and stability of a state-
of-the-art, modern instrument.
All of the sound-shaping controls of the OB-6 are accessible on its front
panel, packing a tremendous amount of power and versatility into a
compact, easy-to-use format.
Each of the OB-6’s parameters are explained in later sections of this
manual. But don’t hesitate to dive right in and start turning knobs and
pressing buttons before you begin reading. You can always get back to
where you started, even if you have no idea what you’re doing. So start
exploring and keep your ears and mind open!
