Play Your Favorite Songs with Casio Feel Sync

Put on a song and join in, even if you have never learned its notes. Casio Feel Sync analyzes the music and adjusts the notes you play to harmonize with it as you follow the beat. Play softly or with more energy, use one note or several, and give the song your own expression. Use the included WU-BT10 Wireless MIDI & Audio Adapter to connect a compatible phone or tablet to the Feel Sync app. Import an MP3, WAV, or AIFF music file stored on your device to get started. Streaming services are not supported by Feel Sync.

 

A White CASIOTONE Keyboard for Everyday Play

With 61 touch-responsive keys, 61 AiX tones, and built-in speakers, the CT-FS1WE also invites you to explore playing on your own. Use headphones for private practice or move this portable keyboard to a favorite spot at home. Choose a darker finish with the all-black CASIOTONE CT-FS1BK, which pairs a black case with matching keys.

Sound Samples

Full Sound from a Compact Keyboard

The Horizontal Bass-Reflex System brings depth and presence to the CT-FS1WE’s built-in stereo speakers. Volume Sync EQ helps preserve bass and treble clarity as you turn the volume down, so quieter playing still sounds balanced.

CT-FS1 Touch Response and Wireless Connections

Respond to the music with every touch. Three touch-sensitivity settings let you choose how the keyboard reacts to your playing strength. Layer two tones for a fuller combination, or use the metronome to keep a steady pulse while you practice.

Connect headphones to the PHONES/OUTPUT jack for private listening. Add a compatible sustain pedal from Casio keyboard accessories to hold notes as you move between phrases.

Bluetooth Audio and MIDI with the Included WU-BT10

The included WU-BT10 does more than connect Feel Sync. It also carries Bluetooth audio from a compatible smart device through the keyboard’s speakers and supports wireless MIDI communication. Use CASIO MUSIC SPACE to manage supported instrument settings, including tone selection, from your device.

How Casio Feel Sync Works

The app analyzes a song’s chord progression, melody, and rhythm. Casio’s algorithm then adjusts the notes you trigger on the keyboard in real time. While you follow the tempo, you can vary your rhythm, dynamics, playing range, and number of notes to create your own accompaniment.

CASIOTONE CT-FS1 Feel Sync Puts You in the Song

With the CT-FS1WE, CASIOTONE invites you to take part in the music you already love. Feel Sync lets you add your own playing to a favorite recording, keeping the notes in harmony while you decide how to express them. Follow the song’s tempo and experiment with a light touch, stronger accents, or different groups of keys.

You do not need to memorize the melody or chord changes before taking part. The app analyzes the selected song, and the CT-FS1WE adjusts the notes you play in real time. Your sense of rhythm and expression shapes what you hear.

Find Your Way to Play with Casio Feel Sync

Join a Favorite Recording

Choose a track stored on your device and add your playing as it runs. You can enjoy taking part without first working out every note of the song.

Accompany Your Own Singing

Play along with an instrumental track and sing over the accompaniment you create. Experiment with how often you play and how strongly you strike the keys to support your voice.
Starting musicians often find it difficult to sing and play at the same time. With CASIOTONE Feel Sync technology, the CT-FS1WE keyboard makes it simple to play along, allowing you to focus more on singing.
