Enjoy the pure musicality of the keyboard while developing your unique style. Discover the 61 carefully selected tones, from Advanced Tones to Casio Classic Tones, that will take you on a journey through Casio’s history. Make the music your own. Define yourself through sound.
Sound That Truly Moves You
The AiX Sound Source technology is at the heart of the CT-S1, authentically reproducing the distinctive sound of each instrument. Keyboard players can choose from 61 exquisitely crafted tones – including acoustic piano, electric piano, and organ. You’re sure to find your favorites. Casio Advanced Tones were developed by sound experts, allowing you to experience full power with modern ease.
Rebirth of Timeless Instruments
We analyzed the sound and structure of vintage musical instruments used in hits from the past to the present and brought them to life with our unique technology. We even added Casio Classic Tones. We captured the legendary sounds of our own extensive range of keyboards and synthesizers, like the Casiotone 201, to celebrate the debut of our electronic instruments from the 1980s. Create the authentic sound of great musicians.
Sound That Brings the Room to Life
Experience dynamic sounds with the newly developed integrated speaker system of the CT-S1. The innovative Horizontal Bass Reflex technology and specially designed speakers deliver pure, clear tones with powerful bass punch in a sleek, compact form. Take it a step further and indulge in rich soundscapes amid the full power of surround sound. With the Volume-Sync EQ function, which automatically adjusts bass and treble presence even at low volumes, you get excellent sound quality at every decibel.
Connect With Your Music
The CT-S1 will keep inspiring you. Bring your creative ideas to life. With the Wireless MIDI & Audio Adapter WU-BT10* you can pair your smartphone or tablet with your keyboard and listen to or play your favorite songs through the CT-S1’s powerful speaker system. The Chordana Play app lets you personalize your musical experience. Change the key and adjust the tempo in audio mode. Suppress melody or accompaniment to turn your favorite music into a backing track and jam along. The learning mode uses MIDI capability so you can customize your lessons and have more fun practicing. Other MIDI-capable apps and external devices ensure no limits to experimenting, as you explore new and entertaining ways to listen, customize, and create musical experiences.
