last night I wanted to play, but suddenly I recognized there is a huge delay of 1-3 sec when I'm playing.
for example when I press the 3rd fret on guitar, after a recognizable delay it shows in the game.
I cannot play at all.
the guitar has a terrible delay, i did the calibration again. also the batterys are good.
I tried it again today and still same problem. also changed the battery but no good
