I'm a fan of the show, but it's troubling to me that because part of their music is automated, as noted in the anecdote, the music director wasn't able to stop the train to adjust to the live experience. That's concerning."
This is true of many current shows that use click tracks that include pre-recorded music, vocals, loops, or technical automation linked to the click. It's very difficult to just stop the ship. Think of how Hamilton would be if an Ableton snafu happened, like it did here.
I happened to be at the show last night and everyone did what they could to make it as smooth as possible. It was very difficult for the actor, dancers, and musicians to get back on track, but they did and it was just a moment of live theatre. And I did see the conductor and associate conductor trying their best to cue in Ben, but it was just a difficult situation, probably one of the hardest sequences to cue if something like this happened.
