This is my first electronic set. I have an Alesis dm4 and I made some pads from old toms. I used Quartz percussion triggers with the harness. And mesh heads. I can hear the snare but it is not very sensitive. I have to really hit it hard to get a sound and need to hit close to the cone area. I reset the dm4 back to factory settings. I can't figure out how to program it. I don't know if there is a problem with the triggers or the module. I am having a hard time understanding the dm4 manual. Can someone tell me how to program an input to a channel?
