CT-FS1WE
Designed to be different!
With the CASIOTONE CT-FS1BK and CT-FS1WE, CASIO introduces striking models with an all-black or all-white keybed. These two design statements, with a contemporary, monochrome aesthetic, perfectly showcase the great sound quality and the portable identity of the CASIOTONE series.
The new additions to the CASIOTONE series, CT-FS1BK (all-black) and CT-FS1WE (all-white), retain the core specifications and intuitive, music-first interface of the original CT-S1, now presented in striking pure black or white. The result is a contemporary visual statement that complements CASIOTONE’s great-sounding, portable identity. Additionally, a new function, Feel Sync and its App, invites even non-musicians to start making music.

“Feel Sync” is the latest evolution in musical immersion from CASIO that lets anyone play in harmony from the first touch of the keyboard. Begin by playing a song stored on your device using the dedicated app, then just follow along with the rhythm and play the keys however feels natural to you, anyway you like.
The CASIO CT-FS1 keyboard comes equipped with the Feel Sync function.
Thanks to Feel Sync, the way you play can be guided by your thoughts and feelings. It allows you to add your own form of expression to the songs you love and discover a deeper sense of joy by feeling one with the music.
The Feel Sync App will be launched in Europe on November 11, 2026, except in Serbia, Moldova, North Macedonia, Albania, Kosovo, Bosnia and Herzigovina, and Ukraine, which are scheduled for a later date.
Note: Feel Sync requires the use of music files that have been stored on your device. The supported file formats are WAV, AIFF, and MP3. Streaming services, which includes but is not limited to subscription-based services, are not supported by Feel Sync app.
HOW TO GET STARTED WITH FEEL SYNC
First, Download the Feel Sync App
To begin your journey with Feel Sync and the music you love, start by downloading the app using your smart device.
Connect the CT-FS1 to the App.
Plug the Wireless MIDI & Audio Adaptor (WU-BT10) that is included with the CT-FS1, into the keyboard.
Seamlessly connect via Bluetooth with the Feel Sync app.
Choose a Song You Love.
Start by selecting the option to “Add a Song” from within the app and select a music file stored on your smart device.
The selected song will then be imported from your smart device into the app.
Play Any Way You Like.
Start by tapping the ”Play” button in the app.
When the song begins playing, try playing gently and then strongly, one key at a time to the rhythm, or playing several keys together at a slower pace. Explore different ways to play that feel natural to you and your notes will naturally harmonize with the song.
HOW FEEL SYNC WORKS
First, the app analyzes the chosen song.
It accurately analyzes the chosen song’s chord progression, melody and rhythm, while CASIO’s proprietary algorithm works in the background to adjust your playing in real time. As long as you play in time with the tempo of the song, it doesn't matter what keys you press, the notes will still be adjusted to stay in harmony with the song.
You can then change the rhythm, dynamics, keyboard range, or number of notes you play to create your own unique ways to express playing your favorite songs!
You can use one half of the keyboard as a Feel Sync “zone” while the other half can be kept for standard playing. This allows experienced players and those who have never played a keyboard before to enjoy performing together to the same song.
