As the official curmudgeon of this list, I'd like to say that I just got 7.1 a half hour ago, installed it, and tried the Follow Tempo option. It is utterly great. I tried massive accelerandi/ritardandi and sudden tempo changes, etc. and it did very, very well. Sometimes if a sudden change is too much it helps to break the audio file in two at that point, but otherwise... Job well done! Best Wishes, Michael A. Levine
