I’ve had a freeze when testing a footswitch too. Had to reboot the desk to clear it. This was entirely repeatable, not a random one off.
It was quite an old switch, and I think the contact was probably dirty, as, when I measured it, it read O/C when open, but about 150ohms when closed, so I put the problem it down to that.
If it helps, it was a dual, momentary switch, and the ring circuit was the one that caused problems. I’d assigned it as a DCA mute.
Another switch has not given me any problems so far.
I’ve not tried a switch with nothing assigned. I may have time to test that tomorrow.
Alex from the Allen&Heath Support wrote to me:
“After speaking with our software team, they have confirmed that this is a known issue and a fix will be included in the next firmware release.” He didn´t mention a release date…;)
I think I need to go back to this next time I have the desk in front of me, and some spare time. Maybe I’d just not assigned the buttons correctly.
Also, I’ve now cleaned up the old footswitch, which has a nicer action & form factor that the other so I’d prefer to use that if I feel I can trust it.
