Strange noise on tape

I just bought an OP-1 and there’s something happenning that I don’t if it’s normal or not:
whenever I press the Tape button and start to play it, I hear some constant “tick” on the left headphone. The sounds I create can be heard normally on right headphone.

Is this normal?

sounds like u might have PO Sync on in the BPM screen.
change it to another mode like free or beat match.
