The Original. Reimagined. 

Casio introduced the world’s first electronic keyboard in 1980, bringing the gift of music to millions of people.

Forty two 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 an integrated carry handle, piano-shaped keys, longer battery life, smooth corners and a slim profile make this the perfect introduction to music.

Choose from any of the 122 high-quality sounds and hear your performance through the built-in speakers, or plug in some headphones for silent practice (sold separately). 

Beautifully Simple

Using the CT-S100 couldn't be easier. The unique panel design makes selecting sounds and rhythms quick and easy.

Weighing just 3.3kg, the CT-S100 fits into any lifestyle with ease. A 9.5 volt power supply is sold separately or you can just use 6 AA batteries for music on the move.

The unique keyboard design is a clever combination of style and rugged, reliable build quality. When not in use, the carry handle holds a music rest. 

Use Music Apps and Games

The CT-S100 can connect to any computer or mobile device via the USB host connection on the back of the instrument (a separate cable is required).

This means that you can use the CT-S100 as a MIDI controller and have access to a whole new world of music apps and games (availabile separately) to make learning music fun. 

Online Learning Included

The CT-S100 includes free access to online music lessons from the Casio Music Academy. Watch and participate in a series of online tutorials to help you build secure musical skills, designed by a team of music educators.

These lessons are not time-limited or free trials, they're there for you for as long as you own your Casio keyboard.
