tr8 definitely sends midi out and the normal expectable cc mapping from gui is of course super easy.
i am sure at the minimum, my pack is wrong. nothing happens regarding scrolling.
no force quitting though 
not sure how to map the on/off buttons as they didn’t work with tr8 buttons
and getting some aspect of the scroll into gui in order to assign it with cc.
those appear to be the hurdles.
RODRIGO, YES I AM SCREAMING INTENTIONALLY. YOU ARE AMAZING. AH-MAZ-ING.
