This thing (for me) has been such a pain to set up with Logic Pro X (and maybe that's Logic's fault) it's currently sitting in a draw. Shame as would be useful to control expression and such like for orchestral work, but having tried the Korg editor, and Logic preferences, it just wasn't behaving properly (but having said that, maybe that's me at fault). But if something is more of a pain to use than a help, it kind of gets bypassed. Am thinking of giving it a second life linked to my KeyStep Pro to see if there is a way of using it to control certain midi parameters on my Modular Rack that respond to midi (like the BitBox Micro). We shall see - when I have a spare hour to waste on it.
But for me, out of the box, with Logic Pro, couldn't get it to work properly, including following a couple of YouTube videos!
