Mux Problem?

[Karaoke Kiwi]

I have been having a problem with Mux tracks!

I like to play them at the start of my show to encourage customers to sing along.

The problem is that when I add the Mux track it does not set the Mux option to Vocal-L or Vocal-R but defaults to both!

I have to remember to set them manually at the strart of each track.

I have the Mux option selected in the song properties through edit song and thought that this would do the trick but it doesn't.

Has anyone else experienced/fixed this problem?

Cheers
