indeed the midi chart doesn’t mention CC7 as recognised, so it will be silently ignored.

in the midish archive, there is a message from 2008 about the « fcurve » function to correct velocity :

I don't see anything referencing using the volume channel, only the velocity of key ON messages (at least I think thats what I'm reading). I'm attaching a screen shot of the page, not sure if it will attach right to the list.
