Got a HD 500 and I like to occasionally set up some of those FS buttons to turn on or off certain effects. So I kind of know how to assign those FS buttons.. (I also use LINE 6 POD HD500 edit on my PC). The problem I am having is some of the FS buttons are set to "MULTI" while its toggeling multiple effects on and off.. I don't want this, I only want the FS to control ONE effect. I can't seem to figure out how to get this off of MULTI.. Anyone know?
