Thanks for the assistance. The following resolved my issue:

– Unplug the USB cables from the pedal

– Delete the pedals in the Mac OS AudioMIDI Setup

– reconnect the pedals via USB

– relaunch H9 Control

Initially, after removing the pedals from AudioMIDI setup and plugging them back in, I got a communication error in H9 Control. But quitting and relaunching H9 Control resolved it.

Much appreciated!
