Hoping someone can help. I'm able to add a Midi Melody track to a new song (using a Midi keyboard controller) and can hear it fine. However, when I add a Midi Melody track to an existing song (Melody track), I can see in the notation that it records fine onto the Melody track, but I cannot hear it on playback. I've tried mute/unmute, erasing the track and trying again, but nothing seems to work.
