Human League used it at the album "Dare"! Trio used it at the song Da Da Da"! Some rumours saying that Depeche Mode used it at the album "Construction Time Again" Do you get the chance to try it (it¥s hard to find) you should know that you¥re doing the programming in the calculator mode. YES!!! It¥s a built in calculator!!! Casio first released the machine as a calculator with a built in synthesizer, but later had to change the description. People saw it as a music instrument!
Comments About the Sounds:
Completely cold, but still fantastic. Think about the music coming from an old computergame, but richer timbres.
