Oh no... the Xilinx chip actually handles very little.  There are no
fewer than 7 high powered E-mu ASICs in there!  To do all the
processing they're doing, you'd probably need several GHz Pentiums!

Z-plane, contrary to popular belief, doesn't have to do with the
realtime interpolation.  Rather, it refers to the discrete version of
the S-plane, which is a very funky and complicated math thing which
I'd probably have a hard time explaining, partly because I don't
understand it completely myself!

Thanks for the endorsement!
