Sequential is led by legendary instrument designer and Grammy-winner Dave Smith, the founder of Sequential Circuits in 1974. In 1977 Dave designed the Prophet-5, the world’s first fully-programmable polyphonic synth, and the first musical instrument with an embedded microprocessor.

The product lineup has grown to include the Prophet X, Prophet Rev2, Prophet-6, OB-6 (with Tom Oberheim), Pro 2, and Prophet 12 synthesizers, and the Tempest drum machine (with Roger Linn).
