Millions of people have their first musical experiences with a Casiotone keyboard. For many it is the beginning of a lifelong passion, for some even an imprint that later turns the hobby into a career. The new models, SA-50 and SA-51, continue CASIO's vision of enabling as many people as possible to actively play music. The new models guarantee improved sound, playability and expression. SA-50 and SA-51 both feature improved direct access, include new metronome and reverb functions as well as transpose and octave shift functions.
