No big complaints. Does what I expected

I sing in a choir, and having this app on my phone enables me to plunk out my part wherever I am and whenever I happen to think of it (assuming i have my sheet music handy). One of the annoyances about it is that when I go to scroll the keyboard, when I first touch that control it jumps so far and so fast that its hard to tell whether Im looking at the octave above where I was or the octave below where I was. Very disorienting, but i eventually get where i need to be. This is on iphone 5.
