Welcome to the forum.

I would not do anything different and what I did was "jump in with both feet" made some mistakes, gots lots of help here on the forum and had a lot of fun doing it . . . and I still am.

Regarding mastering the software . . . for what I use it for, live gig tracks, while not mastered I do have a good grip on what I want and how to get it. But mastering the software as a whole I am not sure anyone (some may be closer than others) has mastered the software in it's entirety.

PS: You might want to post this on the off topic forum.

Later,
