Thanks to all. A proper respond to my question. Mac, I do understand about freeze/ unfreeze. I have over 225 songs which I have edited to my satisfaction. The fact that BB will not let me select a bar or a group of bars to freeze or unfreeze has been mentioned by others, including myself in the past. That feature alone would merit a version change IMHO. MY goal was this: Have Jim {guitarist} record the parts that he would play live, as the second part of my duo. I could then, perform as a single act as need be. I will still have the parts recorded as planed, with out the ability to make a key change.-------Leon
