I can not claim the author of the manual was drunk when writing it, but I understand that some people are wondering. I must say it is the worst manual I have come across (and I read many of them each year). It should rapidly be redone. The 5 tutorials I have seen are not good either, especially the two on Beat Agent are bad.
I also agree that the lack of styles is a let down. I am too a GA user since the early GA2 days. Buying expansion packs might send the price in total up to be very high.
