Ok I'll try doing it this way, otherwise I'll have to exclude the song because it becomes unusable, or better to redo the song with the right volumes to be able to use it again.
Thanks for your answer.
This anomaly happened to me both on two pieces by the same author, of which one piece is fine and the other does not allow me to play on it.
On another Madonna of the same I can't use it for the same problem. Can you edit a single dlc to correct it?
