I think it's more the audiences getting bored sitting there listening for hours of solo arranger KB instrumentals.
A full tip jar is always a good sign that audience boredom does not exist...plus, if you can't keep listener tedium at bay playing instrumentals on any of the recently made arranger keyboards, it's probably time to take up another profession, perhaps tollbooth operator or parking booth attendant.
