I can say that since the Endwalker launch I have this issue and it got worse after the patch.

I do enjoy the game as I can and love it, but for someone that is musician this kind of issue really upsets me!

unlike some fan boys who have already commented here, even though I love this game, I know there are things that can and should be improved and this, mainly, is one of them.
I know they may not know what causes the problem or where exactly it is, but not recognizing that there is a problem having a thread already with so many comments containing good information is simply dishonest, something I didn't expect from Square Enix.

As a customer we all have a right to demand a full working product, that is what we expect when we buy something. I trust they'll find and solve the problem, I hope at least. But for now their behavior about this issue is disappointing.
