Well, I finally just exported it as a midi file, thinking that if any notes were missing in the bass track, I could just copy and paste to fill the empty measures, but lo and behold it worked just fine...no missing bass notes. So it's fine for now. I just need to record one piano track over it and it will be done. The words "thank you" do not come close to how grateful I am for all your help. I wrote the song decades ago for a friends wedding. My grandsons wedding is almost a miracle so this means the world to me.
