The special END character controls the functioning of the Player.
While playing the last chorus, the Player will end the song with a Fermata at the bar indicated by the END character. The Fermata symbol on its own is not recognized by the player.
This is useful for a song that includes a turnaround at the end that goes to a chord that is not the final chord.
If no END character is present, the Player will look at the final chord; if it’s the root or the dominant of the key signature it will play a root chord, otherwise it will simply end on the last chord.

Note: As of now, there is no Fade Out or ritardando feature implemented in the player.
