"usually Pop adopted Hip Hop production"

True. And I think Hip Hop beat sampling became more synonymous with sampling. Perhaps in a rare instance of parallel development, Pop was more focused on vocal effects (the intro to the Reflex for example) than beats. Influential on today's autotune culture in many ways.

Great the way you touched on the SP1200 as well. It's always interesting to consider how the gear influences the approach to music making.
