61-key portable keyboard

The Casio CT-S1RD is a 61 full-size key electronic keyboard with touch response. It weighs 9.92 pounds and measures 36.61 inches wide by 10.15 inches deep by 3.26 inches high. The instrument includes 61 AiX-powered tones led by a stereo grand piano voice. A bass-reflex stereo speaker system with surround effect handles monitoring without external gear.

Beginners and mobile players

This model suits beginners and mobile players who need a lightweight, battery-capable instrument for practice or casual performance. The class-compliant USB-MIDI connection works with the free Chordana Play app for learning assistance. Buyers who require weighted hammer-action keys or extensive professional sound-editing controls should look at other instruments.

The package ships with an AC adapter and a music rest so the keyboard is ready for mains-powered use immediately. Six AA batteries are not included but can be added for portable operation. An optional WU-BT1 Bluetooth MIDI/audio adapter enables wireless connectivity with compatible devices. A 3.5 mm headphone jack allows private practice sessions.
