I pretty much agree with Glen, especially the part about starting out with Music Creator 6.
LE is a capable program, but it is a stripped to the bone version of X1. Unfortunately, the documentation for LE (at least in past versions) is not stripped, and refers to many things you simply do not have.
As a result, diligently following the documentation can lead to much frustration for a new user.
MC6 is a more fully rounded package, and is a great startup program. Some users have even found that it is all they really need. If you find that you do need more, you will be familiar with the interface, and be more prepared for the more advanced versions.
How easy is it for a total beginner?
Well, it's not, entirely, but it's doable. The initial learning curve is nearly vertical. Don't let that dissuade you.
Plan on spending a few weeks learning the ropes.
And don't try to absorb it all at once. Take your time. As you learn your way around, it will become quite easy.
And don't be afraid to ask questions in the appropriate forum. We're here to help.
