Casio unveils the Casiotone CT-FS1 keyboard to correct off-pitch notes automatically

Casio has launched the Casiotone CT-FS1, a 61-key portable keyboard designed to prevent players from hitting wrong notes by dynamically matching their playing to music in real time. The instrument is available in the United States, priced at $399.99 according to Notebookcheck or $400 according to Engadget, and reaches Europe this month for €399 in Midnight Black and Alpine White.

The keyboard relies on Casio's new Feel Sync feature paired with a companion mobile app and an included WU-BT10 wireless Bluetooth adapter. The software analyzes a track's melody, chord progression, and rhythm, shifting triggered notes into harmony while allowing the user to dictate timing, rhythm, and dynamics. The app includes 70 preloaded songs and supports imported MP3, WAV, and AIFF files, though streaming services do not work. Players can also split the keyboard into two zones, enabling a beginner to use Feel Sync on one side while an experienced player plays standard notes on the other. [1][2]

Based on the hardware layout of the CT-S1 from 2021, the CT-FS1 features Casio's AiX Sound Source with 61 tones, 64-note polyphony, and built-in stereo speakers with surround effects. Each unit sports a fully monochrome exterior where the keybed matches the cabinet color. The 4.5 kg keyboard operates on an included AC adapter or six AA batteries. [1][2]
