It's making weird, rainbow lights and it's freaking me out.

Here’s a YouTube I just made.

Additional info not in videothat maybe doesn’t matter: the colors of the Track/Record/-/+ buttons change depending on what Shift has selected. All of which is different than it was.
It started around the time I was in the app, in Gadget, and possibly also USB midi to a Volca… but I’ve done that before without weirdness.

Much thanks in advance for any help! It’s kinda freaking me out, even though things are still playing normally as best I can tell.

It´s possessed by the Rainbow Ghost! :o :o :o :o

(did you try the factory reset?)
