Thanks for all your help!
Now.....
A: I have one song that I want to fade out.
Its programmed to fade but won't doesn't fade out completely- it still ends.
How do I perform this function?
B: I have another song where I bring instruments in/out at different bar settings.
I can do that (believe it or not!)
What I can't do is bring some instruments in at a lower volume for the final chorus.
I thought 'change by' would work by entering the volume number in the box but it didn't.
I don't want it to get 'louder by' a certain bar or 'fade by' a certain bar.
I just want a lower volume all the through the last chorus.

Also, can you point me to videos that cover these steps?
Thanks AGAIN.
