Maybe I am having the same problem GE had. I cannot seem to display 2 tracks in the sample editor one above the other – extremely useful to match one vocal track’s timing against another when using VariAudio. Selecting both events and opening the editor opens both, sure, but then you can only select one at a time from the drop down next to “Edit Active Audio Event only”. I have pored through the manual, searched, and tried random things in Cubase. No dice.
