Pete14 To play devil’s advocate, imagine a classical pianist refusing to play a concert on a CFX because “that instrument is better-suited for Jazzers,” and having the production team running out in a haste to find an actual, physical D to haul up into the concert stage and move the already-there CFX out
To give you a realistic perspective, big concert halls have several concert grands of different companies, and international competitions have a day or two for competitors to choose their favorite pianos for their performances. Moving these pianos are not easy, but unlocked wheels and other things I cannot see would help the movers in the process. Even in universities there are different pianos to choose from. So what you say is completely within doable context and don’t involve another side of town.
There was once a pianist who broke a string on one of the higher registers of the piano at National Center for the Performing Arts in my country few years ago, and another piano rose from mechanisms from the bottom of the stage, or something like that. The piano change took only minutes.
