Hanger you assigned Crow as the output of Awake?
If not, here are the steps:
Press Key 1 to go to the global pages, then scroll to the Params page (it’s the furthest right). One of the parameters will be Output. Scroll through the options till you see something along the lines of crowJFii or something. That should do it.
If sound doesn’t start, try power cycling both devices, plugging the norns back in to crow and give it another shot
