Casiotone CT-S1BK/WE/RD


Casio introduced the world’s first electronic keyboard in 1980, bringing the gift of music and creativity to millions of people.
Nearly forty years later, the new Casiotone series changes everything once again, building on Casio’s renowned traditions of innovation, versatility and value for money.




Clever and Compact 

The new Casiotone series is designed to be the world’s most portable 61-note keyboard. New features such as piano-shaped keys, longer battery life, smooth corners and a slim profile make this the perfect introduction to music.

The new LCD screen and jog wheel mean less buttons and a clear, uncluttered panel. The CT-S1 is the easiest keyboard to operate in its class.
