I’m working on some scores for wind band. When I listen back to the score, often a drone-type sound appears. It’s as though previous long notes continue to play through even though there’s nothing in the score. It’s different every time I play back and also comes through at random when transferring the file to mp4 or midi. These long sounds only stop when I close symphony pro. They continue when the stop button is pressed. I’m working on a new iPad Pro.
Any ideas why this is happening?
