I have kept up with this thread for nearly all 41 pages and perhaps I missed this somewhere but, I can't find the CC for the Rotary X/Y. Is this something that will just find its way to the final version?
from what i understand, there is no CC# available. i think it's the same even on the XL with some blocks that have added XY capability (not present in non-XLs).
so the only(?) way to do it is save the X vs Y per Scene.
