About Feel Sync
“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 this Feel Sync app, then just follow along with the rhythm and play the keys however feels natural to you, anyway you like.
Explore New Ways to Play using Feel Sync
●Play Along with the Music You Love
“Add a Song” from within the app and select a music file stored on your smart device. You can enjoy the feeling of performing as if you were part of your favorite band or playing alongside your favorite artist, just by playing in time with the tempo of your favorite song.
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.
●Add Your Own Accompaniment and Sing Along
"Add your own accompaniments for you to sing along to! You can do this by playing the keyboard along to an instrumental track or one that doesn’t feature vocals.
Enjoy singing and playing along to your own unique accompaniment!"
●Play Together, Your Own Way
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.
Using the app expands the ways you can engage with music and express yourself through performance.
