Can you open up mr. datalooper, remove the switch and email a photo & your address to firstname.lastname@example.org? It sounds like you need a replacement switch sent out. We’ve gone through a few manufacturers, so I just want to verify which switch type you have.
DataLooper launched in 2018 as a way to streamline Live Looping using a software based system. It has since grown into a full fledged, customizable MIDI controller.
