Changing keys in Microstudio recordings

[Ernie]

This year we went on a cruise. We took along our traveling CDG's with our favorite songs. On the label, along each song we would have -1, -2, 0 etc. whatever the song key needed to be changed to. Some nights they would have a person who knew how to change the keys, and some nights they would have a different person who did not know how to change the keys. What do I need to do to make up a traveling CDG where I can change the key of the songs I want changed and record them? That way if someone doesn't know how, or their machine doesn't have the capability to change keys, then it's not a problem. I can't find anything in Microstudio on how to do this, or if it can be done.

Thanks,
Ernie
