I just got the Axe-Fx II to replace my Axe-Fx Standard. First off, I love the II!!! However, I am having issues getting the Roland FC-300 midi foot controller expression pedals to work properly with the Axe-Fx II. Specifically, trying to get EXPR 1 pedal on the FC-300 to serve as a volume pedal. Used to work seamlessly on the Standard, but not on the II. I get it to do volume adjustments, but it is very sporadic and random....sometimes volume increases when the toe is up, other times it increases when the toe goes down....rarely does the volume go all the way down in any movement of the pedal, etc......I tried calibrating the pedal using the FC-300 utility to no avail. Anybody else having issues? Thanks!
