All the other FCB1010 firmware versions allowed MIDI Thru to be turned off.  Reading through the manual, it seems that it doesn't - MIDI Thru is always on.  Any chance this can be added? (Feature Request!)

It seems easier to unplug the MIDI cable than to go to the editor and write a command to disable MIDI Thru. But I'm probably missing something here? (in a TinyBox setup this is part of the more extensive MIDI filtering functionality which is not available in UnO2)
