Korg Poly800/EX800 Users

I bought a poly 800 about 4 months ago, and don't really use it.  I do
alot of Jens Johansson style lead playing and was wondering if this
hawk 800 upgrade allows you to do pwm with the DCO's, and perhaps a
Mono/Unison mode.  I have tried and tried again to get a real polysix
(what johansson uses for his patch), but find they are really
expensive.  If there is a way to do this with the hawk-800 i may just
have to purchase one, and finally get some use out of this synth,
otherwise, I may just sell it.  
thanks
