Ensoniq was founded by Robert Yannes, the creator of the SID, and Al Charpentier, one of the designers of the VIC-II, and Bruce Crockett, whose history I do not know.
InfoWorld - Apr 26, 1982 - Page 18: "Bruce Crockett is Commodore's vice-president of systems manufacturing and the man who keeps the Santa Ciara assembly plant running smoothly."
Before that "Liquid Gold: The Story Of Liquid Crystal Displays And The Creation Of An Industry" page 134 "he was a former operations manager for LEDs at Fairchild"
Apparently Tramiel had a thing for not keeping verbal agreements (suppliers being huge example). Whole C64 team was promised bonuses after release, instead they got "be glad you have a job" pep talk and the smart ones left.
