I currently have two H9s, a Tonex, and a Morningstar MC6 Pro. I have installed a USB hub under my board so that all the pedals can have their USB cables always connected which is very convenient for plugging into a computer. The problem with this setup is that the H9s do not respond to Midi signals sent via a 5-pin cable by the Morningstar when a USB Cable is connected. Even if the other end of the cable isn’t connected to anything. It seems as though MIDI is disabled if the H9 detects the presence of a USB cable. Can this be fixed?
