I think this is inappropriate. These effects are often applied locally. And I can't think of why we need to deal with these issues in a singing voice synthesis engine. I added the effector before to benchmark against the current mainstream singing voice synthesis software during audition (they have updated similar functions), but are more functions crossing the line? If this continues, it will become increasingly bloated
