Hi - is there a way to save the mixer settings from the front panel? I've been trying to use my Audio4+ in a live situation. I send a click to a drummer and backing tracks to FOH. It used to be saved, but the last few times I've powered the rig on, the volume on output 4 (going to the drummer's ear) is all the way down. It's easy enough to change it from the front panel, but it's not retained in case I need to power cycle my rack. Is there a way to "save" the settings that way, without going into the mixer app on the ipad?
