Mac,

Thanks for your response!

Here's what I did:

from the original song file which was then and is now fine I went to file, clicked "save song as",changed the name and clicked save.I got a new version named as requested. I do not remember if I tried to play it before going into bar settings and setting up some mutes and return to normal entries for the solo acoustic guitar track. (It's a bluegrass style and I added a RT shuffle style fiddle on the melody track which made the stock Guitar track too busy...that's why I'm pulling the guitar in and out)

After doing three Mute-return to normal entries I tried to play it back and got no audio. Then I went back to the original and it plays fine as do all other works in progress in the BIAB song folder.

As far as saving a song file another way such as your suggestion to use explorer..I do not know how to do that and was not aware that the save method I'm using could lead to trouble.

Thanks!

Brian
