first a there are few little dots I when i press encoder 2nd time ….like 4 or 5 f them ?….randomly spaced ..then it completely shuts off, like unplugging it …right now at least when i change presets with midi controller, it still does program changes, on what i already had programed, and assigned to midi controller presets …if i do the factory reset, might not change anymore if it is broke  …was gonna get another delay anyways  …so probably wait on reset until i buy it
