if you record the melody on chanel 4 and then open the score view you can set the lyrics to every note and when you play the song the lyrics will follow as karaoke, another way to fix this is to load the lyrics in to Audya but you must have the name on the lyrics and the name on the midifile the same and the lyrics must have the txt. and the song will have mid. and when you play the song push record and turn page on the lyrics, and when the song is ready push save, the midifile will show the lyrics
good luck
