No I didn't change anything actually. I had this problem before the last software update. I don't think it comes from the settings since the other cymbal is ok.
I've the same problem.After the last OS upgrade the edge and bell zones are not working properly, especially at low/medium velocity.I hope that with the next upgrade we can have access to more parameters to adjust cymbals triggering.
Actually, the OS did not change anything to me. Since one cymbal works great and not the other one, it only comes from the cymbal.
