[AH] What did Roland etc. think the real-world use for drum machines was, pre-dance music? (calling old heads)

I recently got a CR-8000, and it is absolutely lovely. Along with
other machines I have or love like the TR-77, CR-78, etc. it's
insanely well-designed with the auto-fill functionality, crash cymbal
reserve, etc.
What did the manufacturers really think these were being used for?
What were they designed FOR? Outside of Sly Stone and some more niche
artists, you really didn't hear these things in recorded music. Did
Roland et. al. think that these were being sold purely for practice?
For recordings? For electronic music? For traditional music? For
cocktail acts?
