Robin,
It was good to meet you yesterday. I’m glad we were able to help you flash your Quaverato.
It seems that now your Quaverato thinks the tap switch is being held down when you power it on. Make sure the tap foot switch wires aren’t twisted or connected somehow. We put this function on the this pedal so customers can see what software version they have on their microcontroller.
Check those wires and let me know if you still can’t get it going.
Good luck!
