I just received a FX8 third hand I believe. I reset to factory settings as Previous owner tweaked the function buttons. After reading the manual and tweaking all of the tweaks I could find concerning tap tempo the tap tempo will not work. The Led blinks the new tempo and the tempo page shows a tempo change but no dice on effecting the delay. I am hoping it is a simple fix or maybe I am not holding my mouth just right. For me this unit will be worthless without the tap tempo any suggestions would be helpful and appreciated
