hi Korakios, Hellfire said it all
I feel like I've read other topics here in the past discussing how to get into these cymbals.. maybe it wasn't always a ride, but they're the same for accessing the internals (except ride has 3 zones so extra sensor and cabling).
When I first got my DM10 the bell was difficult to trigger, had to hit it really hard and spot on to get a good sound
Then after spending a few months with my kit I realized that I was trying to hit it with the tip most of the time, not the shank of the stick (I'd been out of drumming for about 25 yrs so kinda forgot some technique)
Next I cranked up the sensitivity of the bell (can be a bit confusing in the module to get to the bell settings instead of the bow). With that up higher and hitting it on one of the sides of the bell with the shank with enough force I'm getting good sound every time. But sometimes I do take it down soft and quiet but still using the shank I can get more subdued tones, or hitting with the tip but a bit harder than I would with the shank, I can usually trigger it even if I hit tip to the front of the bell.
But best results will always be shank to the side of the bell with a good solid force. I think if you open it up and try to mod it you may end up worse off, but I'm all for trying things like that out just make sure you either have another as a backup if it's destroyed, or can afford a new one (I've bought the ride for about $130 CDN).
Still would recommend upping the sensitivity, perhaps trying various threshold settings (maybe it has trouble triggering quickly one after another).
Good luck and keep us posted!
