Thanks for telling us how you solved this. I have discussed it with 3 engineers and we were all scratching our heads.
Tip: If you want to make the sweep velocity very fast across each word (it might make your ad for your Band appear a bit better), after you tap the spacebar to insert a word to the music, immediately tap the Ctrl key to stop the sweep. The entire word will sweep as fast as your delay between Spacebar and Ctrl key. Then tap the next word in with the Spacebar (SB). If you want to make them all sweep quickly, tap SB Ctrl, SB Ctrl, etc. as fast as you can. Or, you could just tap SB very fast for as many words as you have to place, then tap Ctrl to end the sweep. They will all sweep as fast as you tapped SB, up to the maximum sweeping speed the Karaoke CDG format allows.
ENJOY!
