For some reason last week my footswitch has changed. I now have to tap twice to advance songs, hit accent, pause beat…everything. Is there a setting for this? It is really annoying trying to hit it twice in the middle of a song to get it to work.
run the detect footswitch thing again ,and it should reset itself
could also be something to do with a FW upgrade? Some hardware wipes all settings when upgrading FW or an OS. Just a thought 
Also, the settings can reset when you load a new project from the computer to the SD card.
I ran the detect footswitch thing and it reset back to normal. Thank You!!!
