Ron;

Thank you for answering in detail. I am trying to learn this stuff as fast as I can because I like making music not fighting with all the details. But one must, to a certain extent to get the basics of any program. BB is just better than others I have used, but different also. There was another auto-accompany program I used alot ( starts with a "J") that allows you to save individual tracks when you get a compose you like, and only re-compose tracks, and portions of tracks until you get something you like. I am just used to that I guess. But with the RT's in the picture, I will never go back to that program. BB is superior now, in it's field, and I'm sure will only get better. I think I just need to read what you have provided, and it will solve the problems I have been having. I got so excited when I got BB, that I just kind of blundered ahead because I don't like reading manuals. Although I have found much more help on this forum than reading the manual twice!
I'm now ready to get into the vocal end of things, and am going to tackle the TC harmonizer and all of that.

Thank you again, you and the others have cleared up much.
