Yeah I play Extremly alot, but i think it happend because my keyboard has a function called Aftertouch, it is when you strike the keys hard enough it will make a fill-in or other stuff , depens what you assign, and plus Roland made default setting for key velocity on High

that makes me strike keys way to hard to if I want an aftertouch to work. Or maybe I was drumming alittle too hard.
But how much would a repair cost(aproximetly,about $50 or about $200 or $10)?
