thanks, that make sense now!! tried it and it works finally. one more thing which im confused about
you said " You may want to route all music channel strips to an aux, put in a directional mixer plug-in, and use that to pan - it will keep you from losing volume when you pan hard to the right".
how do i set up an aux in mainstage?? and do i put the directional mixer plug in on the aux channel strip only? assuming i set up one aux channel strip ? or do i put it on the backing tracks?? on the directional mixer plug in i just grab the direction thing clockwise?? to pan right, do i need to do anything with the spread setting? thanks so much for your help.
