As someone who paid many of these Beethoven sonatas growing up, I love this. It's like guitar hero! You get to not worry about a whole class of things and just focus on your timing and dynamics.

It would be really cool to be able to work voicing in, but I can't think of a way short of another piano!

Random question, but... why is everyone in this thread referring to volume as velocity?? I feel like I'm taking crazy pills.
