I have a Stage, and my effect button 4 stopped working a couple days ago. I updated the firmware last night trying to see if it would remedy itself, but it didn't. I also contacted support and they had me hold the system and rig button when starting it to reset the cache etc. but that did nothing.
I've searched and found one thread here about a broken effect button, but it was a separate button so I wasn't sure if it's a similar problem/solution.
Anyone have the problem with button 4? or is it the same issue people are having with button 3?
