Hi Twilly,
After trying different stuff I realized that it was not the looper itself that was broken, it was the foot controller. When the FC wasn’t connected the looper worked as usual.
I opened the FC just to check if there was some loose cables but I didn’t find anything suspicious so I put it together again and then…it worked
I hope you have the same luck.
After I’ve been restarting a couple of times it now doesnt react at all. No LEDs lights up (exept for the tempo/clix).
