One of my friends and I recently got into jamming in-game with the performance action, but we noticed that we always came in at the wrong times. Today I met up with my friend and we tried jamming in FFXIV to see what was up, and it turns out there's a huge delay, like a few seconds of delay between when a key is pressed on the performer, and when the listener hears the note being played.

I just want to see if the community at large also knew that this issue existed. This really explains why all of those musicians who are performing always get so upset when I start harmonizing and jamming out with them. It's cause they hear me coming in and playing the wrong notes at the wrong times xD Even if on my screen I'm playing with them perfectly.
