it's different from your brainlock on a pattern, because a brainlock happens when you rely totally on muscle memory instead of reading the pattern.
But what happens when, instead of getting a brainlock because of a burnout on a map (aka, repeating it too much), you get unable to hit a pattern on a map because the pattern is so repetitive that it loses meaning for your brain, even though you can totally read it, your hands can't keep the speed and the rythm you where going.
how do you fix it? i mean, or correct it, it happens to me only on World Sound
