## Summary

Casio has launched the Casiotone CT-FS1, a portable keyboard designed to let learners play along with songs without producing notes outside the song’s harmony. Its Feel Sync feature may help beginners practise rhythm and creative expression with less worry about mistakes.

The $399.99 keyboard has 61 touch-responsive keys, built-in stereo speakers, Bluetooth and a headphone jack, and runs on AA batteries or a power adapter. Feel Sync works through a companion app for iOS and Android: users import a song, and the keyboard adjusts the notes they play to fit its harmony, while they remain responsible for timing. The keyboard can also be split into two zones, allowing one player to use Feel Sync while another plays normally.
