I almost never use notation because it's so difficult. But it sure is a hassle going back and forth to a program that actually writes notation. All I want to do is add a note or two and change a duration here or there and I find I have to learn three different "modes" just to begin, and switch between them, depending on what I want to do. Why? I feel I might make some progress if I had some sense as to what the purpose was. What is the purpose of having three notation modes?
