Morrison's ARP synthesizer solos, which produced a distinct whining sound, became hugely influential in the West Coast hip-hop scene of the '80s and '90s and were sampled by a number of rap acts, including N.W.A. (on "Dopeman" and "Gangsta, Gangsta"), Ice Cube (on "Wicked" and "Ghetto Bird"), and DJ Jazzy Jeff & The Fresh Prince (on "Boom! Shake the Room
"), among others.
Morrison explained how he found the synthesizer and brought it to the studio: "I would travel all over the world looking for tech to use on our tracks. As time would have it, I found an ARP Soloist in a shop somewhere in NYC. Immediately, it sung to me and I heard an Arabian-style riff that had 'worm' written all over it. I bought this synth and went into the studio with it. During the session, I remember everyone staring through the control room glass with puzzled looks on their faces, that was, until I recorded the Granny voice to cement the track together. It was lots of fun and the rest is history."
