Thank you, Sherry! Yes, it is very helpful. I had some vague suspicions along those lines, but I have never played around with the possibilities. I tried a few instrument sounds and noticed the change, but am not familiar enough with it to know what I am doing. It is a lot of trial and error. I just added drum and bass tracks to "Patsy's Song" and believe it or not, I actually got it on the right meter. I really did it the hard way though. I copied the tracks from a downloaded version of "Alfie" and the drum part fits well. I had to change the key for the bass part, then of course, I had to change each note to fit the chords in my song, because mine is a zillion miles away from "Alfie" changes. I still have to tweak the rhythm in places to make the ritards etc fit better, but I think Mark will tell me to do that with piano roll. I have to experiment a lot more, but now I am almost motivated to add tracks for strings, a brass section and maybe a trumpet or tenor sax solo. It gets crazy doesn't it? Thanks again and thank you also for the drum files. I downloaded some from the web site you mentioned, I can't wait to sample your's. Fred
