It sounds like the GM thinks the big silver colored Tyro looks tacky on top of the grand piano. I'm not sure if he'd like any keyboard , even a black one on on top of the grand piano. Maybe put your keyboard on a regular stand to the side of the grand piano or put your midi file tracks on a device like a laptop or tablet. I know it sucks when these GMs nit pick on little things like this, but it's the way it is...
