Control works but the problem is that Direct Updater "cannot be opened because of a problem" "check with the developer to make sure eventide direct updater works with this version of OS X. You may need to reinstall the application. Be sure to install any available updates for the application in iOS 10." As such my only option given (via Control)is to update the software which I did just to take a chance to see if it helped, but it did not.
Well if the Control works and you've updated the firmware then you don't need the direct updater, and it means it's not the firmware's problem.
Could you try reset your iPad's bluetooth and network settings, and restart it and see if that helps?
