Fade effect

Since 1.2.2 you can choose different settings for fade in and fade out effect. By default fade is disabled (FadeType.NONE).

Enabling fade

You have to set FadeType to enable fade effect. Default duration is 60 ticks (3 seconds).

Fade fadeIn = sp.getFadeIn(); //sp is SongPlayer; you can also use getFadeOut
fadeIn.setFadeType(FadeType.LINEAR);
fadeIn.setDuration(60); //in ticks!
