I've now noticed that in the live version of Magic the piano is "alive" and it is played by no one. How it can be possible? It like a "loop station"?

It's a piano that works with the midi controller, you can play it because it is a piano, but you can control it with a computer, like you know in fix you when chris plays it but you hear a organ and not a piano? Because from the computer through the midi controller they changed from "piano sound" to "organ sound".

I think it really looks awesome. At least they try to be more ''live'' this way and I like it:) They also did this in the TOTP performance of Christmas Lights :)
