I’ve had a few problems getting the foot pedals working correctly with POD Farm 2 and I think I’ve finally solved my problem. I’m using Windows 7 and it seems as though if I launch POD Farm after my computer has been on Sleep/Hibernate, POD Farm will totally refuse to recognise and accept the input from my pedals, which are connected via 1/4 inch jacks to the back of my UX2. The only solution I’ve found so far is to totally reboot my computer which is a bit of a pain, but it does work.
The following video (not created be me) outlines how to go about setting it up inside POD Farm, and a quick Google search will reveal plenty more on YouTube and other sites, so I’m not going to go through how to do that. If you do get stuck though, please leave me a comment and I’ll do my best to help out if I can.
