“Okuda learned for the first time that the “rock” bassline she had written for the Casiotone keyboard had become a sensation around the world.”
A first-year Casio hire wrote a two-bar preset for a ¥35,000 toy keyboard and labelled it rock. Jamaican producers turned it into the riddim behind hundreds of songs. She found out from a Japanese music magazine in 1986. Casio sold the keyboards. The credit went to everyone but the woman who wrote the bassline.
