Casio 61-Key Keyboard, Red

At the heart of the CT-S1, AiX Sound Source technology produces the authentic sounds and experiences of every instrument. Keyboardists can choose from 61 carefully crafted tones, including acoustic piano, electric piano, and organ, so you can be sure to find your favorites. Developed by expert engineers, Casio's ADVANCED TONES allow you to experience the grandeur and atmosphere of live performance with modern ease.

Footprints that lead the way to the future. We analyzed the sounds and construction of vintage instruments used in hit songs from the past and brought them to life using our unique technology. Now you're part of the band. We've even added CASIO CLASSIC TONES, making the old new again. To celebrate the release of our electronic musical instruments in the 1980s, we captured the iconic sounds of our rich keyboard and synthesizer lineage, such as the Casiotone 201.
Match the authentic sound of great musicians.
