Karaoke Home Producer does require you to enter the Lyrics in a .txt file, then import it into KHProducer. If the .wav song is 3 minutes long, it takes 3 minutes to tap the spacebar and Ctrl keys to place the lyrics in sync. If it is good enough, you're done! However, if you are a perfectionist, it will take several trys at placing the lyrics in sync... until you get tired of doing it, or make it acceptable. Ear-Hand coordination and fast neural timing are needed to use KHProducer. Some folks have more than others, and they will do a better job. However, anyone can tap in a song.
If a song is 3 minutes and you have to tap it in 4 times to get it acceptable, that is only 12 minutes. I can't imagine taking even 30 minutes (10 times!) to do a 3 minute song.
I assume by "Confetti" you mention that you are seeing random dots outside the characters or dots inside the characters turning a different color.
This is a typical failure mode of a CD-Recorder that has not been certified for CDG. Believe me, we earn our money on testing our CDG certified drives!
