Hello everyone
I’m new in the monome community, in fact I’ve just purchased a factory Norns from 3/4 days
Strange behavior today. I was running a keyboard trough the audio stereo in. Since I was using greyhole app, nothing wrong happened. Then I switched to loom, to enjoy some shimmering and the screen it started to glitch and then became all black, with the patch still running.
I’m not able to switch off norns because the screen didn’t show nothing at all.
Please help if u can 
Many thank in advance
