No more pads triggering other pads. Also, something weird. I think its where I stored the pads but the stock pads feel soft as the fat pads now. Had them in a shoebox in the closet for 3 years with temps at 76 to 100 F.
All my samples are still on there too 
i honestly think the reason they trigger other pads is cause the nipples fit to tight into the holes, im still gonna take mine appart and drill the holes out a lady's private parts hair bigger..someone should let mike at mpcstuff know about this, i dont have it happen too much anymore, but at first it happened a lot, or a pad would get stuck playing in trim mode, like i would let off the pad and it wouldnt let off, the sample would still play, pad 1 mainly, also some times when i hit pad 1 nothing would happen, this caused me to replace my seniors underneath only to find out they were fine.. glad ur 500 is better, u should let mike know, cause that is wack that dudes 40$ pads put you off of playing with ur 500...
