[QLab] two songs playing at once

[Joanne Burgess]

In performance last evening two songs accidentally were started at the same time, (They are both just sound cues, one to follow the other, but the computer got jogged - or something)

I did not know how to stop one without stopping the other, and I didn't want to leave the dancers on the floor without music.  So they had to dance to the songs overtop of each other.  It was not beautiful.

Is there a way to stop a song playing over another without stopping the entire thing?

Thanks, 
Joe
