Good answer Eileen.
I load a song,which has an OTS loaded,and proceed to audition them before I memorize one. After turning on LH(in my case),I make any needed adjustments in volume etc,and memorize. If,when trying another OTS,you may decide you want that in another spot,or find something else.
It may take a little more time,but worth it,as I don't have to go back to it later to tweek.
