The Heart of a Champion

At the core of the CT-S1, the AiX Sound Source technology produces the true sounds and experiences of each instrument. Keyboardists can choose from 61 exquisitely crafted tones – including acoustic piano, electric piano, and organ – so you’re guaranteed to find your favorites. Developed by expert engineers, Casio’s ADVANCED TONES allow you to experience the grandeur and flair of performance with modern ease.

Timeless Instruments Reborn

Footprints that pioneer your future. We’ve analyzed the sound and structure of vintage musical instruments used in hit songs from the past to the present and brought them to life using our unique technology. Now you’re with the band. We’ve even included CASIO CLASSIC TONES, allowing old to become new again. We’ve captured the iconic sounds of our own rich lineage of keyboards and synthesizers, such as the Casiotone 201, to celebrate the 1980s debut of our electronic musical instruments.
Tune into the authentic sound of great musicians.

Sound That Brings the Room to Life

Experience dynamic sounds with the CT-S1’s newly developed built-in speaker system. The innovative Horizontal Bass Reflex technology and specially designed speakers provide clear, crisp notes with a powerful bass ‘punch’ in a chic and compact form. Take your musical immersion experience a step further and lose yourself in lush soundscapes amidst the full power of surround sound. Maintain superior sound quality at any decibel with the Volume-Sync EQ function that automatically adjusts the presence of bass and treble, even at low volumes.

Keep It Simple. Keep It Real.

With the pure essence of musical instruments at its core, the essential keys, speakers, and minimalist design add to the CT-S1’s simple functionality and operation, so you experience the best in playability and can concentrate on the music.
