Glad you liked it Linda.  When I first auditioned that effect I nearly did back flips.  I couldn't believe I was hearing that effect from the WK's.  I'm certain it was on the MZ-2000, but I was so happy to see they carried over those effects.  I tell you what..., for the money the WK's have a lot going for them.
