Background Vocals

[mindonstrike]

I'm sure providing a multiplex button is on their list, but no clue how far up the list it is since most professional KJ's don't bother with the vocalized tracks. Even most of those kinds of disks don't show the vocalized tracks in the database because most of us won't bother importing them (at least the old database-I don't have the upgrade yet).

gduns is correct if your mixer has a multiplex option (and your cables are plugged in correctly) that should do it however you don't want to do that more than you have to because in stereo some of the instruments are going to be split up to certain degrees on both channels.

Here's a hint if you hear vocals in both your speakers (while in stereo mode) then they are background vocals and you can't get rid of them, you can tone them down a little sometimes by adjusting the channel eq's.
If you only hear vocals in one speaker only then it is a multiplexed song.
