Oberheim OB-6 Keyboard is a six-voice analogue polyphonic synthesizer with two discrete voltage-controlled oscillators per voice and a two-pole state-variable filter based on the classic SEM design.

The keyboard version uses a 49-note semi-weighted keybed with velocity and aftertouch. X-Mod, dual effects, a polyphonic step sequencer and an arpeggiator extend the direct analogue signal path.
