High pitched sounds were done with a Casio Rapman keyboard. Some of the beats were done with a toy plastic "pink radio" that Darren Hayman gave me. I recently discovered that he used that same electro snare sound on the Hefner song "Mary Lee".
Juno 106 and Prophet 600 were the melodic synths.
I actually met a girl with the name Radiosa.
