SPD SX High Pads Issue
in my SPD SX I realized that the "high" pads (that ones that cover the high angled edge ) are really less sensible that the other six "plain" pads.
If I strike with my stick one of the plain pads with a low dinamyc stroke it sound perfectly in a low volume, but if the same dynamic I strike one of the three top pads it doesn't sound!!!
It have to be stroke harder to make some noise.
Is it normal?
Should I sent my machine back to the Roland assistance?
Thanks for any suggestion
