Oh well i got my AR MK2 delivered 2 days before Christmas and I have to repackage it and send it back. 
Only got a chance to really try it out the other day but once I turn it on all the lights just continously flash or it just sticks on the OS page on start up.
Tried a factory reset and it worked for an hour… Switched it off and back on again and boom flashing lights again.
No idea what the problem is but sending it back to BAX MUSIC Tuesday for a replacement.
An expensive piece of gear to be faulty within hours of turning on.
Hope the new one doesn’t act the same way
