Hi Joanne.

Yes, it's a very useful technique. It's also called "Ducking" when it's used to reduce the volume of a track which has a voice-over - the music metaphorically ducks it's head!

Having said that, I don't think it's possible with RealBand at the moment. We'd need Re-wire, or something like that which could route signals within the program and this has been on the wish-list as long as I can remember.

Maybe someone out there knows a work-around? rharv, where are you?

ROG.
