He mentions the sequential multi-trak in this GQ article (In Search of Chad Hugo) "Like when he recalls his first professional DJ gigs (“I had a Casio keyboard SK5 and a little microphone…”), or when he met Pharrell (“I had a TASCAM 4-track Portastudio at the crib, Casio keyboards, a sequential multi-track…”), "

He also mentions his first keyboard being a sequential in a pitchfork article (The Neptunes’ Chad Hugo on the Music That Made Him) "My first keyboard was a Sequential—I have it right here actually. [rolls chair over to the keyboard] It’s synth-based, really low sine wave stuff, and it was part of my love for machines."
