I was noticing this as well today. If I do some quiet rolls on the snare it seems quiet, then all of a sudden at a certain midi value the volume increases drastically. When it’s quiet, it also sounds like there’s a lot of reverb, so I’m wondering if the snare mic is shutting off at a certain midi value, leaving only the room mics to pic up the snare. Then the snare mic kicks back in at certain midi level. I’ve tried messing with the ‘soft’ velocity control but it doesn’t seem to help.

This sound like your problem as well?
