Having a huge issue with the 720 looper… it’s in rec/play/dub … using fade out function, set at “6” (the reason I bought the pedal) …. recording short loop… maybe 10 seconds, and after initial loop is set, and it in “play” it suddenly erases about half the loop. so in “play”, touching nothing and the loop appears to just glitch and vanish, but not the whole thing, just part of it. obviously a huge problem for live performance. please help.
