Who really invented the first Digital Vinyl System

Interesting article trying to answer the question: who really invented the first Digital Vinyl System. "There has been some controversy in the last few years over the question of who actually invented the concept behind the Digital Vinyl System (DVS) currently on the market today, which was first launched as Final Scratch). My name is Steven Carroll, I was the primary electronic engineer / main designer / sole director of Intimidation and during the nineties I designed 4 Intimidation DJ mixers which were renowned for their unique and innovative features (the most notorious feature probably being 'Kill Switches' and 'Rotary Kills' a concept now used everywhere) and each of my designs and features were widely plagiarized by the rest of the audio / DJ manufactures in this space."
