Roger Troutman was another Elite multi-instrumentalist in music history, people really don't understand how gifted he was because they only pay attention to the Talk-Box, but people don't know he was equally as cold on the guitar as he was on the keys. He was cut from the same cloth as Prince as a musician & composer, his arrangements were other wordly.
He comes from Ohio just like The Isley Brothers, Parliament Funkadelic, Bootsy Collins, Bobby Womack, The Ojays, The Ohio Players, The Legendary Screamin Jay Hawkins, Bull Moose Jackson (who was a beast Saxophonist), The Dazz Band & several others.
Roger was one of the most prolific songwriters & producers, he was a phenemonal creator & true visionary, he basically revolutionized the modulated sound decades before autotune became popular, but he didn't use it how modern artists use it today to mask their inability to sing, he used the talk-box as an instrument to assist with the overall ambiance of the music.
Roger was special, he was your favorite artists favorite artist. Both Michael Jackson & Prince respected him a great deal & they (Roger/Zapp) even went on tour together with Prince back in the day because they were both label mates on Warner Bros. Roger actually wrote Itchin for Your Twitchin as a way to pay homage & respect to Prince & years later Prince made Dance 4 Me off his LotusFlower album as a way to pay his respects back to Roger.
