hello, unfortunately I have to re-upload this thread because my helix also suffers from the same problem. I've tried all kinds of inputs and even after sending it for repair here in milan, the problem recurs. The firmware version is 3.15, I tried factory restore but alas without luck.
For those who have had this experience, how did you solve it? Is it possible for line6 to replace the pedalboard with a new one?
