Sequential is an iconic American synthesizer manufacturer, renowned for its pioneering contributions to the development of analogue and hybrid synthesizers. Founded in 1978 by Dave Smith, the company (initially known as Sequential Circuits) revolutionized the music industry with its Prophet-5, the first fully programmable polyphonic synthesizer with digital patch memory. This groundbreaking instrument allowed musicians to store and recall sounds, making it a landmark development in music technology. The Prophet-5 became a defining instrument of the late 1970s and 1980s, widely used by artists across genres, from pop and rock to electronic and film scoring.

In recent years, under the leadership of Dave Smith, Sequential has continued to push boundaries with modern re-imaginings of classic instruments as well as entirely new designs. Notable products include the Prophet Rev2, Pro 3, OB-6 (in collaboration with Tom Oberheim), and the highly acclaimed Prophet-6—all of which blend vintage-inspired analogue circuitry with contemporary features like MIDI integration and digital control. Sequential’s synths are celebrated for their rich sound, robust build quality, and expressive interfaces, making them favourites among musicians, producers, and sound designers alike. The company remains a key player in the world of synthesizers, bridging the gap between vintage warmth and modern versatility.
