When I use Key Editor to manually adjust a note’s length using the mouse, this happens: instead of changing the original note’s length, a new note is superimposed over it. I must have changed a setting somewhere but I’ve not seen this before. What have I done?
Update: The notes were recorded in real time; when I used Key Editor I found that each note had been duplicated four times, which accounts for the note appearing underneath when I reduced the length of what turned out to be the topmost note. I have no idea why this is happening.
