Non-existing cc parameter in envelope

It doesn't say what it is. I clicked last touched and it appeared. There is nothing to check or uncheck. Using envelope points to automate it does nothing. Can't get rid of it. :confused:

Clicked "last touched" what? There's several. How do you know it's a CC parameter?

I think he probably means an FX parameter. Plug-ins sometimes export fairly random parameters, the last parameter the FX may have adjusted internally could have been temporary or hidden from the user. There should be no harm in just clearing and removing the envelope.
