Hmm… Mine seems to be dead? It was working for a bit, maybe pushed too many buttons and flipped it too much. When I turn it on the loop button barely lights up for a bit then nothing. unit seems dead. I uploaded the latest firmware, and It seemed to do everything right. Lights going up and down and animation every 20 sec per instruction on uploading firmware. Same thing on boot up.
Is there a reset all somewhere? I put a sound source into IN and monitor OUT and nothing.
