If I was to want to have a track use a different effect at certain places in a song is that possible in RB? Like if I wanted to add chorusing to just the chorus of a song, can I select measures X to measure Y and apply an effect (over the top of what is already there) to only those measures?

I never tried it and I am not at home to try it right now, but I wondered if anybody can answer that before I try and find out it isn't possible. I know I could clone that section to another track and do it that way but it just seems "sexier" somehow to apply effects to specific zones in a track.
