I don't think the OP is intending to use tap tempo. He just wants to keep the AX8 in sync with the DAW.With the Axe-Fx II (if I sync it to the tempo/clock in Live 10) using the tap tempo switch on my foot controller makes very weird things happen -- temporarily until the clock forces things back on track. I have to change CC mapping to have the Tap Tempo CC control the DAW (not the Axe). I don't know if you can do that in Logic Pro X.
