I open a new Cakewalk file.
I open the Key/Tempo Change under View, and change the key do my desired.
I open the Piano Roll View, and find that nothing has changed.
At this point, I'm expecting something like the notes on the left hand side of the screen to, well, do what they're supposed to do (I wouldn't know; this has been an issue ever since getting Cakewalk), but as I said, nothing happens. Am I missing something?
