I am actually having this issue but with swells. I am contacting support for it but it would be interesting to know if someone had this issue was able to fix it and pass along that knowledge to the rest of us.
My specific problem is on my Helix Floor. The expression pedal for swells cuts in hard at 30% "volume" instead of easing in gently from 0% like it used to. I noticed this when I upgraded to 3.80.0. During worship services, I usually will do swells with shimmers quietly while pastor is talking and I had no issues. But since that update, it cuts in hard and I can really hear it in the IEM and it's bad. I have not tweaked anything at all and I checked how the volume was set for swells in the chain and it's fine. Both pedal boards do it (we also have a church Helix Floor). So I will taking my woes to Line6 support but if I find a solution on my own while waiting on their reply, I will be sure to report it here so others can fix this on their units.
