Difficult to use

Maybe I’m not looking at the right part but it’s very hard to do anything

Somewhat Limited

A reasonable app’ but somewhat limited and, though reasonable, is not entirely intuitive .

★★★★★Patrick Q. Kelly4/7/2012
from the developer

you can change the timing of the notes by touching the note value in the control bar. - a popover appears with many options. - these are for playback. - not notation. rewriting the notes as different values seems a pointless feature for this app. so the playback IS changeable. just not the appearance on the staff. press the play button and hear the rhythmic pattern you chose. I hope you try it and update your "review"
