My internet comes from some weird hacky program on a rooted child's tablet connected to my computer by usb all through a 3g phone's wifi.. let's just say, I'm patient when it comes to loading.... (did that intro scare you?).. it loaded up superfast. no problem. sounds played. looks good to me!
Also, as a musician, I can't stop playing with it. Same thing happens when I find toy keyboards...
This is just my random opinion, but, I assume you left out the sharps/flats for simplicity and learning.. but then why start on B? with the minor second and all.. why not start on C? a key which has no sharps/flats anyway?
