HiHat not triggering anymore

Hello, love the MegaDrum Dmitri, thanks again! Unfortunately I have ran across an issue all of the sudden. My HiHat input isn’t working.. cymbals sensor seems ok, and the path has too. Also the soldered connections seem solid. Anyone have any ideas? Everything else works fine it seems including the control pedal. Could I bypass and use another input if it’s dead for some reason? Any help is appreciated. Thanks again
