Everything works like charm except from the DSP/Fx bypass. when i turn off the pedal from MIDI or even from H9 footswitch itself  effect trails are instantly cut off as if the pedal is in hard or dsp bypass mode

It would be good to try resetting your H9s system settings by turning it off and turning it on again with the right footswitch and the HotKnob pressed (the button in the upper left hand corner of the H9).  The last update seems to require that the system settings be cleared.

Thank you gkellum,

I’ve tried to reset the pedal as you suggested. Trails worked until I’ve set again the pedal in Pre/post routing.  With h9  set in that routing  DSP+FX doesn’t work. The fx trails are immediatly cut off. 🙁

Could you check this with other units?
