probably best to read the other thread . there are some videos on it too.
in short - you set it to ‘learn mode’ and any cc it picks up is added to a list’… they can be from computer or midi out of a box.
once the list is done , when you move the dial it’ll inc/dec all of those cc’s .
that thread / main website will definitely help as i havent used it.
this is from the thread.
