I guess "mastering" is entirely subjective and may take some time. But, as for use, I'd say fairly easy if you are comfortable with software for music in general. The first time I ever used it was for a part in a live PA. I created my soundbank with it on the drive to the venue from the passenger seat, having never opened it before. Now, I was using it for something very basic there, but I think you can catch the drift. I don't use Ableton a lot. Generally, the only time I use it is when I'm working with others who use Ableton. But, it was definitely coded with user friendliness in mind. I've never looked at a manual for the thing and figured out how to get it to do what I wanted it to do. So, basically, if it's something you want to work with, chances are you'll be able to make it work.
