When you press the + SONG button at the bottom of the screen the new song should jump up where you can see it, no scrolling. If you press + SONG in the middle of the screen you can see the new song. Makes you want to have a dummy song at the end instead of adding at the end.
When you press + SONG button and start a new song, the default drum set is on the none selection. It seems to play the standard set if you leave it on none. Get rid on none and let it be standard like it already is, then at least sometime you won’t have to change it.
