One simple answer to that Hellboy..Yes and markedly so.
Quicker screen, quicker O/S, better graphics and of course.......screen goes up, screen goes down, screen goes up, screeen goes down...DOH!.....lol

I do feel your frustration at the speed of the PA1, bugged the hell out of me too!!

Another thing that is quicker is the load time of PCM's. I use the Realdrums a fair bit and have them linked into a set with some Steinway pianos and they load so much quicker.
