# List of Casio keyboards

Casio electronic musical keyboards were first manufactured in June 1979 and continue to be made by Casio today. Older units in the Casio line, despite being limited, were and still are popular with independent artists like Jack Stauber and Outkast for their unique and sometimes haunting sounds, particularly their pulse-code modulation keyboards. The original Casiotone line was abbreviated to CT in the mid-1980s but has continued to feature full-sized keys. MT and PT lines typically feature mini keys and the VL line features push-button keys. Most Casio keyboards feature automated accompaniment sections which may include drums, bass, chords and harmonies. Many Casio keyboards can be run on both mains electricity and battery power. Some Casio keyboards were integrated into other electronic audio equipment, including AM/FM radios and cassette decks. Casio keyboards from the 1980s and 1990s are occasionally used by ambitious sound designers who use circuit bending, a process in which a person rewires the circuitry in innovative ways in an attempt to increase functionality, to extend the keyboard's sound palettes. The following list includes some of the instruments' basic specifications and is not exhaustive.
