Multiplex

Siglos Karaoke Player allows you to play multiplex CD+G discs. Multiplex is a special type of CD+G karaoke disc -- there are two tracks for each song on the disc, one track in karaoke format and the other track with the lead vocals so you can learn the song.

 Siglos Karaoke Player allows to turn on and off the lead vocals during playback using Multiplex slider. 

This gives you the opportunity to turn off the lead vocals as needed.
