XDJ-RX: BEAT EFFECTS MALFUNCTION

Hello.

I don't know what happend with my XDJ-RX.

I have a problem with the Beat Effects Controller. I tried all the beat effects using the control switch and the only effects that worked were ECHO, REVERB, TRANS and PITCH. And this effects, are not at the right place of the controller.

What could be happening? Hardware malfunction?

Can you help me?

Thanks
