I just picked up the HX Effects (sold my POD HD500x) because I have an EVH 5150 iii and didn't need all of the amp/cab models.  Anyways, I'm currently using MIDI to switch between the clean/crunch/lead channels and notice a lag that I didn't see on the HD500x.  I'm curious as to if there is some way for me to program one of the pedal outs to do the 3 amp channel switching.  So I'd have 3 different patches (clean,rhythym,lead) changing go channel 1,2 and 3.  I hope I'm making sense.   Thanks,
