Timeless Instruments Reborn

Footprints that pioneer your future. We’ve analysed the sound and structure of vintage musical instruments used in hit songs from the past to the present, and brought them to life using our unique technology. Now you’re with the band. We’ve even included CASIO CLASSIC TONES, allowing old to become new again. We’ve captured the iconic sounds of our own rich lineage of keyboard and synthesisers, such as the Casiotone 201, to celebrate the 1980s debut of our electronic musical instruments.

Tune into the authentic sound of great musicians.
