CASIO CT-S1-76WE 76-key musical keyboard

76-key portable digital piano

The Casio CT-S1-76WE is a 76-key portable digital piano with touch-sensitive full-size keys and 61 AiX-powered tones including a stereo grand piano. It weighs 11.68 pounds and includes a 13 watt bass-reflex stereo speaker system. The instrument connects via USB to the Casio Music Space App and supports an optional WU-BT10 Bluetooth MIDI/Audio adapter. It is suited for players of all skill levels seeking a compact, battery-capable keyboard.

76 touch-sensitive keys

The decisive specification is the 76 full-size keys with touch response, which provides a shorter range than an 88-key board but remains expressive for practice, performance and composition. Buyers who require the full 88-key piano range for advanced classical repertoire will need a different instrument.

USB app control and audio connectivity

USB connectivity enables direct control of the Casio Music Space App for learning and sound management without extra hardware. The 13 watt bass-reflex stereo speakers deliver amplified sound for personal monitoring or small spaces, while aux-in and headphone outputs allow silent practice or external amplification. The optional WU-BT10 adapter adds wireless MIDI and audio streaming if desired.
