i route all my voices (and other gear) through the rfx mixer on my e4, and often i find that i want to tweak a voice in the mix, meaning i want to hear everything else, with effects, while i'm tweaking. however, because i'm in mutli/preset/sample edit mode and not in rfx mode, i don't hear anything, so all my changes are blind. i would work so much faster if i could hear the changes as i make them, is there a way to do this?

thanks,
paul
