Product Concept

The innovative AiX sound source is overturning expectations of what a digital keyboard can be.

For 2018, Casio is taking its experience in detailed sound creation from the development of the AiR sound source and developing the new AiX sound source for digital keyboards, a complete re-creation from scratch of the keyboard sound.
From a reworking of both the sound produced and the instrument’s exterior,the results will be a high-quality sound that overturns traditional expectations of what a digital keyboard can be.
The new sound source promises to offer all keyboardists the experience of a sensational performance.

Exceptional Sound & An Engineer's Voice

Exceptional Sound

Casio leverages some of its most advanced technologies in the CT-X series, creating an unprecedented playing experience for any keyboardist.

Never before has a portable keyboard sounded so good.



The CT-X’s distinctive styling puts a bold face on its incredible sound, and delivers an intuitive-yet-sophisticated playing experience through its easy controls.

Futuristic design

Overlapping crimson rings surround the speakers and ports.
These striking, forward-thinking accents add a powerful visual element to match the powerful sound.

  • * The mesh speaker grille is not actually removable.

Rugged design

The aggressive body styling comprises a bold, angular shape with multi-textured surfaces. This lends an impression of clarity and power, while ensuring that the CT-X can withstand rigorous play.

Cockpit design

Reminiscent of an airplane’s cockpit, the controls are grouped in tiled sections. Each control’s location feels natural, so you can focus on your playing.
