Playback has uneven tempo. It is better some times than others. I have a soundmax sound card and finale 2006 with gpo. When I had this problem with overture, i installed asio4all and it solved the problem. I had to choose asio4all from within overture to fix it. Even with the suggestions I have received so far, I haven't been able to figure out how to make finale 2006 use the asio4all driver. I feel that this would solve the problem if I knew how to do it. Does anybody know how to do this?
