Vocoding voice in SX3

Hi,

I recently bought the Komplete 2 pack, and I've been playing with all
the plug-ins and getting to know them. I tried out Vokator last night
for the 1st time, and I couldn't get it to work. I've read the
manual, and followed the beginning part about setting it up in
Cubase, but I still can't get it to work. What I want to do is vocode
my voice (is this the right terminology??!?!). So can someone tell
me, step by step, how to do this set up in SX3. I've obviously got a
mic input, plus a MIDI keyboard. I want to be able to record my
vocals (dry, without the vocoded effect), record the MIDI notes, and
only hear the vocoded vocals through my speakers when I'm performing.
I've been able to do this long time ago on a demo version of another
vocoder, so I'm hoping I can do the same.

Thanks for any help
