Hello! I have a question about using Line 6 UX2 with external gadgets . I want to use HOT HAND 3 http://www.sourceaudio.net/products/hothand/hothand3.php. Can I connect external gadgets to UX2. Maybe possible through the footswitch? It's not just hot hand 3, but also for other external gadgets that need to be connected directly to UX2. Please explain how to configure UX2 that work with it. Thank :)
