I still suspect I have settings problems. The PG Music software has been excellent. I have been using it off and on for almost it's beginning . At least I remember using it on windows 3. Anyway I have found the problems I have encountered were the result of incorrect settings on my part. Unfortunately I don't have a full understanding of the Audio settings so there in lies the real problem. My PC is a 3.5 GHZ 6 core with 8g memory so I have enough horsepower. I'm running Win 7 64. Other than the conductor and a minor notation issue BIAB has worked great. I use it more since the realtracks came on. I really would like to get the conductor to work right but I don't know what changes to make.
