Needs portrait view, more scales and new screen size!

Portrait orientation would be more appropriate for an app like this, like Filtatron or iKaossilator. And there has to be more scale selection than major or minor. Also, I dont understand why the settings revert when you re-enter the app and the labels disappear after you change them. Oh, and optimize it for the new screen sizes already! They dont even make the iPhone 4 anymore.
