Hi
to answer your question ("can it be done?") I'd need to exactly know how the effect is designed, its structure and parameters….
As far as whatyou report on the H7600, you don't specify what preset you have used or what have you created in Vsig , if you have use it.
Eventide pitch shift have no "sour effect", another detail we'd really need to know what you mean by.
We remain full of curiosity!
Please let's know.
best
I
