I might agree with you if it wasn’t for the fact (already quoted that all other meters work) If icon can get all other meters working then they must have all had there brains transported out of their heads to some distant universe some where just as they were working on the master fader. The point being, if they can work out the other meters but not the master then there must be a problem on Steinbergs end.
I’m sure icon will sort it out by asking Steinberg to get their act together and sort this. This is not just a Steinberg problem as other DAWs don’t work either.
