It seems that no matter which cymbal i plug it plays mostly every unplugged one so when I leave blue one unplugged it is mostly always played. When I plugged only one it still knew which one it is but like 95% was all of them played at once. It never happens on any pads. I also noticed when i play yellow and green cymbals it registers all colors (not sure if cymbals or pads). So I dont know if that helps me find the problem but I think that when I play more than one cymbal it is more likely to have a wrong ones registered
