This should be easy. I'm working on a synth part in the PRV and my notes are only snapping to the Key of C. I know there is a way to set that up in the PRV but I can't figure it out. I think I collapsed the part where you select the scale but I don't know how to bring it back. All I have on the left pane in the PRV is the keyboard.

open the PRV then View(top left) Show/Hide track pane / the in right click on the name of the track on left

Thanks!
