Note-off does not trigger with back-to-back notes in Cantabile and MuLab
Bug reported by @HermanRoyce, moved to separate issue by me.
Notes that end at the same point that another starts do not have a note-off passed to the instrument being played (easily fixed by making the first note end slightly before or after the second starts, in which cases notes-off are sent correctly). I was surprised something this obvious hadn't been picked up before and thought it must be caused by some peculiarity of my particular configuration, or perhaps by my DAW/VST host, but it happens in both Cantabile and MuLab (whether they are playing or not). Presumably, the second note's note-on somehow over-writes the first's note-off.
