if you want the delay off by default you have to save it off in the axe.(bypass it in scene 1 and save, then will always be bypassed when preset is selected unless the switch making the patch change is also sending the delay bypass cc#.for the wahwa to turn it on and off with toe switch you must turn off the auto engage in the axe control modifier page, then in the pod set toe switch for channel 1 toe switch cc toggle (then the cc# for wahwa bypass) the tricky part is getting the wahwa bypass insinc so it is bypassed when exp is on the one you are using for volume and engaged when the exp for the wahwa is on.
How do I get to the axe control modifier page?
Did you set wah control source to Ext Ctrl 4 in preset 2? Modifiers are configured per preset on the Axe.
(unless you have the cc# for delay bypass sending with your patch change command)
This might be whats happening but how do I know?
