Sound That Truly Moves You
Bring vibrancy and emotion to your music with the CT-S1 – a keyboard like no other. Featuring AiX Sound Source, this innovative technology is designed to enable electronic instruments to produce the perfect tones and, combined with the integrated acoustic sound system, bring each note to life.
Recharge yourself with inspiration. Feel energised and encouraged to play more.

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 favourites. 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 analysed 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 keyboard 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.
The CT-S1 brings to life a world of sound to inspire you.

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. Available in black, white or red, the keyboard’s speaker net, with its mixed colour-texture fabric, spans the length of the console, adding to the wide soundscape experience. The sleek look provides the ideal minimal aesthetic, blending seamlessly with any interior setting, and allowing your life and your music to shine.
Bring together life, space, and sound in perfect harmony with the CT-S1.

The CT-S1’s compact design ensures music is always by your side and easy to pick up and play anytime and anywhere. No preparation. No storage hassles. Music and innovation will always be at your fingertips. Its slim body will fit into any space, giving you the flexibility to match your playing style to your mood, with a form that fits into all kinds of tight spots. There are even pins for attaching your favourite strap, so you can experience the freedom of playing without a stand or desk. Whether you’re on your sofa surrounded by family, or relaxing in your bedroom, play whenever and wherever the mood strikes.

Connect with Your Music
The CT-S1 will never stop inspiring you. Bring your creative ideas to life. With the Wireless MIDI & Audio Adaptor WU-BT10*, you can pair your smartphone or tablet to your keyboard, and listen to or play along with your favourite songs through the CT-S1’s powerful speaker system. The Chordana Play app allows you to personalise your experiences. In Audio Mode, change the key and adjust the tempo. Using the 'cancel melody' or 'cancel accompaniment' buttons, turn your favourite music into a backing track and play along. Lesson Mode utilises the MIDI capability to individualise your lessons and make learning fun. Other MIDI-enabled apps and external devices ensure there are no limitations on experimentation as you keep exploring new and fun ways to listen, adapt and create musical experiences.
