Welcome, Martin/

I found an Italian(?) manual for the Midjay Pro, and I'm trying to download the English manual, but so far I haven't found a manual for the FS6 footswitch.
EDIT: Okay, I downloaded the English manual for the Midjay Pro. However, the page that describes how to program a footswitch to control the Midjay Pro's functions-- page 49 of the English manual-- gives almost no information about which functions can be assigned to each of the switches on the FS6 or FS13.
