Dang, I love this concept but I'm pretty disappointed in the input lag! I even went into my PC settings/keyboard driver and couldn't fix it enough to make a difference. I'm a drummer who played with a click in many different settings for years, I feel pretty confident that I'm on time (especially on the really simple stuff that I'm missing). I know it's a free game and all, but it's bummer lol, I'd love to see an updated version!
