In 1980, the original Casiotone CT-201 allowed anyone to make music, regardless of skill level or budget. With the CT-S1, its spiritual successor, we've raised our own bar. The Casiotone CT-S1 is a great-sounding, stylish, ultra- portable keyboard designed for anyone to enjoy playing. Its incredible sound quality makes it an ideal musical partner for beginners and seasoned players alike, and its sleek, portable design makes it fun to play anytime, anywhere. *Includes power supply and music rest.
