Overview
- Casio announced the CT-FS1 on November 3 and the keyboard is available now from Casio’s US store for about $399.99 and at higher prices at some retailers.
- Feel Sync requires the companion iOS or Android app to pre-analyze a locally stored MP3, WAV, or AIFF file and then maps every key press into notes that match the song’s chords as it plays.
- The keyboard includes the WU-BT10 Bluetooth MIDI/audio adapter so the phone runs the analysis and sends corrected note data to the instrument, and a dead phone battery stops the app-enabled play-along while normal keyboard play still works.
- Under the CT-S1 hardware the CT-FS1 keeps 61 touch-responsive full-size keys, Casio’s AiX sound engine with 61 tones and 64-note polyphony, built-in speakers, and a split mode that lets one zone use Feel Sync while the other stays conventional for duet use.
- Casio positions the CT-FS1 as a living-room, beginner-friendly instrument that prioritizes instant, enjoyable play-along experiences rather than formal technique teaching, with tradeoffs including no streaming service support, a monochrome key finish, and no top-panel screen.
