Means: "auto overdub" is highlighted but AUTO-overdubbing does not work if you want to record a *new* loop to a blank track. Overdubbing just works when an *empty* or *full* loop is already running. If *no* loop in the chosen track is running, no AUTO-overdubbing.
Using win 10.
EDIT: my fault. I just hit "RECORD" button again instead of "MARK END" button.
