Both the OB-6 desktop module and the OB-6 keyboard are a collaboration between the two most influential designers in synthesizer history, Dave Smith and Tom Oberheim.
The OB-6 takes on Tom Oberheim's classic bold tone, with its oscillators, 2-pole filter and voltage-controlled amplifiers, and adds modern enhancements like studio effects, polyphonic step sequencer, arpeggiator and more.
