I agree with your general point. So maybe the following is the exception that proves the rule, but:
An acoustic piano has 88 keys, and classical or jazz piano music tends use many of them. Whereas a 60 key electronic keyboard is often subject to the Flock of Seagulls treatment, wherein one key at a time is held down. :) It's roughly like touch typing vs. hunt and peck.
But aside from that example, yes, I think you're onto something.
