Very Good app. If the scrolling is smooth  it will be much much better. Thank you for the good apps. And i have found a problem on setting. I set not to display second score on song setting  it make mute it too. Could you fix it? Futher  do you make it to play karaoke with score and with sound fonts? If so it will be the best on midi apps. Thank for your help and efforts. Very good app.
