I was able to find a solution.The MFC-101 sends extra midi information on every channel no matter what settings. The solution was to filter out everything except PC messages. I’m doing this with an old Tc G-minor midi controller. It responds to PC changes from my MFC-101 and sends them to the PowerCab plus free of extra midi data. Works perfect, but I guess Line6 should update the firmware so it does not freeze up when it gets extra midi data.
