Still getting playback distortion. It sounds like there is a scratch on the record (for those that remember vinyl). Its every beat (and its not the metronome). When I enter a note using the piano keyboard it sounds OK, but playback is distorted. I have just uninstalled Muse 2.1 and reinstalled and the fault in still persisting. Music In you tube plays OK so its no the sound card. There is definately something in MuseScore. I have tried to play with the synthesiser and volume control and they have no effect. I have tried to change instruments and it is there on all of them. Its almost as if there is a phantom stave or track being played. It used to work fine a while ago.
Does anyone have any suggestions.
