Sing along with God! Overhead Slide Program Displays Worship Music Lyrics in real time as they're being sung. Words are shown a line at a time so huge you can read them on the monitor screen from across the room. That way you don't need a projector and you certainly don't need expensive software to show words and lead songs of worship. It comes already packed with with over 300 well loved hymns and real time programmed for several Vineyard modern worship CDs. It's easy to program the advancing of words in real time, and it's also easy to simply load up the words and advance them manually. That way your worship experience can use CDs, sound files, live music, group singing and any combination of them. One set can have some of each. You can prepare a song list that makes it a snap to run a whole set of worship music without fumbling around for files. This thing has a 120 day demo (yes, 120 days!) so try it out and you'll be real happy. There is a list of what CDs it knows on the InspiredCode.net site.
