Charlie,
useful, but real voice and more detailed annotations would be better.
Also, I feel, this should have been done in minimalistic view GUI.

I have started a topic in another section, that seemed have drowned without a real answer.... And if the replies it did receive are true, then it is surprisingly strange. I am talking about this:

So.... was thinking about this and I believe a full song SGU file, showcasing general and more advanced techniques is ABSOLUTELY a must. I would have learned stuff I know now (and I do not know enough as of yet smile ) in about 1/2 the time, IF we had such song file and accompanying video walkthrough explaining how to get to that point. I also believe this should be done by someone at PG who knows better how to get to desired results faster and more effectively using available tools / features.
