Can anyone tell me if there is a way to change the song theme/background on the fly similar to the old VJ mode. We have a big youth event coming up and we like to be able to change the background graphics during the song. I know I can set a theme for each slide before hand, but that does not lend well to the ability to change as to mood of the room changes.

VJ is not available in EW 6. You can compose, but you have to compose from the resource area. You can expand the song and drag the theme to the slide and double click the slides. You can use the preview view and drag the theme to the slide in the preview and go live with it. You can also do the same with preview and live combined mode.
