Hi, Ok setup the Ground Control to cc 65 & 66. Works inconstantly (but better than before) ! Sometime appears to be in sync other times not. Not sure but I think maybe going from a single FX block preset (band taps) to a dual in series preset (Diamond Rain), it looses the correct bypass status. what do you think ? cheers Mike
Mike, I think you didn't read my reply with attention.
Check the values I reported as yours are incorrect.
