Sorry you are having trouble. In order for us to help you, please tell us:
1) What are your connections ?
2) In what way does it not work ?
1) H9 is connected to a midi looper switcher in 2 slots (pre/post)
2) 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
