Hi, I've had the HX Effects for a couple weeks and have already built a nice pedalboard around it and used it for some shows. I'm using a Boss EV-5 as an expression pedal in EXP-1 (currently nothing in the second, plan to use it for amp control as I expand the board and its uses) I see that in the manual the default for wah and whammy effects are an auto engage for the EXP-1 jack. If I add any wah to a preset and turn it on, the Expression pedal works it fine, but the auto engage feature doesn't work, and I'm not finding in the manual or in the menus where to turn that off or on or how to adjust this. So far I've had to use one of the six footswitches to turn off and on the wah, jump to the expression to use it, then go back to the footswitch to turn it off again. Not ideal. Since I've been able to do build presets, multifunction control assignments, snapshots, and just about everything else I've wanted to so far fairly quickly by RTFM... I like to think my reading comprehension is fair. What do I need to do to set and adjust the auto engage feature for wah pedal?
