We did tons of sampling, though, even back then with the Publison, a very odd, early sampler. Prince exploited the living hell out of the Publison. It was the main tool of his work when I first joined the team.
I pulled out the studio's Publison Infernal 90 and sampled and flew the parts together, creating a finished song ready for vocals. The Infernal 90 was the best thing going for digital sampling in 1990, all the flying of parts done basically by hand.
