Bassist here, using my HX One as a simple one pedal setup for gigs. I use the tuner and a handful of presets for octave, chorus etc. I have never used either Tap Tempo or Flux and have turned off the Tap Tempo LED flash.
I upgraded the firmware from 3.71 to 3.81 and decided to to investigate Flux, but I find I can't get the RH pedal to do either Tap Tempo or Flux at all, and the LED is permanently off.
A factory reset restores the expected Tap Tempo and Flux functionality, but as soon as I reload my presets it is disabled once more.
Is there some setting that I might have made that can disable Tap/Flux altogether or have i just run into a bug?
