It worked for me. It creates and envelope from the CC data in the clip (even if it destroys those data, so the cinverted envelope is just a line). Now I am figuring out how to switch to it again after I switch to note filtr. The envelope doesn't stay in options of edit filtr for me to choose it again. again.
Edit: It worked the first time I tried, but now when I wanted to convert another controllers in the same track, the controllers disappeared, but the envelope doesn't even get a focus (because it is visible there, I just cannot select it from the edit filter).
