DL4 expression pedal

[William Walker <billwalker@baymoon.com>]

you should be able to control any parameter, and an ev-5 should work  
although It may not have nearly the range of travel. Just put the  
pedal to heal down, adjust any parameter to your liking, then push the  
toe down and do the same in the looper mode it will commit thst to  
memory without any write function.
