Yeah that stood out to me as well. I think the LEDs are a nice option to have. Piano bars sometimes have big mirrors suspended over the stage so you can see the player’s hands; this is a much more flexible way to achieve a similar effect. The solenoids though…. Oof. To your point, pressing a piano key is so much more than a binary on/off. Digital keyboards are quite good, but still different. It should certainly be possible to make a version of this that works, but (1) binary solenoids ain’t it and (2) the result would be fundamentally different from a traditional piano.
