So, I'm going through the songs on easy and normal for the rewards, and clearly hitting a note but having it not register is probably more annoying than if it was on a higher difficulty. Three times on easy, on the same song, I've had a clearly hit note not register. Orchestra of Smiles? More like Orchestra of Suppressed Rage!

I get that it's probably less of an issue with the game, and more of a hardware issue, though.

Edit: Fourth time's the charm. Anticipating a note not registering yet again made that the most stressful FC on easy ever...
