If cheating is expected then the question should be if midi files or BIAB is professional?
Or, getting back to the entertainer vrs. musicianship question.
I'm sure there is a necessary blending among most here, but I refuse to become an A.O.(appliance operator) by playing records, or pushing buttons on a workstation. To me, the black & white keys are more important.
Less is more. I'll cater to the more discriminating audience. A keyboard, an amp. and a mic. Play "off the cuff".
Sorry, I'm not going to play it like so and so played it and I don't do Celibration or YMCA.
