Hi Guitar Hacker,

I must apologize for not having responded until now.I submitted the post ref adding bass tracks and never opened up the forum to see if anyone had replied. I have just opened BIAB Forum and found your suggestion.

Sincere belated thanks. Using a DAW makes sense to me now. It didn't when I submitted the post.I have been going thru BIAB for Bozo's video tutorial so I have a clearer idea of what BIAB can do.
Newcomers to BIAB really need to take a course in Computer Music Technology before you can get your mind around what you have in your hands with BIAB.
I will try out your suggestions
Best Regards
Steve
