Effects in Musescore

Hi All,

I have a varity of effects that I use in DAWs and they show up in the Musescore effects lists, such as Izotope, Toneboosters and such, but not one works. They all open up in Musescore and I can adjust settings, but they do not change anything.

The dedictaed Musescore effects work fine, it's only the third party effetcs that do not work. Is this normal?
