I have a single bar intro in a song and when I export the song to disk, the first bar is missing. What do I do to fix this? The intro is a single track with just one part, and the track isn't muted. The headphones icon is lit up.

Hi InFocus - It sounds like you may have bounced a selection that didn't include that first bar..? Check the Cycle ruler (the yellow bar), make sure it starts and ends at the start and end of the section you want to bounce, and enable "Export cycle area.." in the Export dialog box..

perfect!
