Just a (contraversial) suggestion:
 Have you tried Korg's own Mono/Poly VST model which comes part of the very
 cheap Analogue Edition 2007 package
 www.korguser.net .... grab the demo version (you'll need a Syncrosoft dongle
 on which to hold the temporary demo license).
 I'm finding it to be a very satisfying substitute for a real Mono/Poly and
 it has capabilities which far exceed the original (up to 128 voices of poly
 / 8 way modulation matrix / host syncable MG's). Run it at 96kHz 24bit or
 higher and you'll find it sounds even more lifelike.
 Oh yeah you'll also get the superb sounding PolySix and MS20 models in the
 package plus Legacy Cell all for around a 1/5th of the price of a real
 Mono/Poly in good condition.
 Just a thought ....
 Cheers
