There are several things that make the bell parameter stuck:
- Bell Variance is dialed in and you try to turn Bell intensity to 0. You often still hear the bell.
- When you are on 100% Bell and then super quickly turn it down to 0 it gets stuck on some intermediate value.
- When you deactivated the plugin and activate it again it can happen that it gets stuck on some bell value, even though your patch has it on 0.
I don’t know if these are all related issues. It does seem like it though, so they are all in the same post.
