On H9 Control, under the PEDAL tab, go to Aux Switch Mappings. There you can assign any CC# you want to Bypass and activate the pedal. Use those same CC#s to program your ES8 ranges. If you don’t want the wah activated when you send the H9 a PC message, then it’s best to save the Q-wah preset in a bypassed state to begin with.

Keep in mind, the H9 won’t allow you to program ranges such that CC#X with values 1 = bypass and 2-127 = activated. This type of programming needs to be done on the ES8 or other MIDI processor.
