Hi All,
With my own pre-occupation with putting aftertouch into my own Polysix, I wasn't aware of the Phyxis aftertouch system from New England Analog. While their webpages don't speak about any Polysix synths with the system, one just popped up on eBay:
http://www.ebay.com/itm/Korg-Polysix-with-Pyxis-Aftertouch-System-/261220003899?ssPageName=ADME:B:SS:US:1123Which has a demo video of the modified Polysix attached to it:

Their aftertouch system looks to be very full featured. It's impressive. I think that there are some user-interface ideas that I can borrow. Cool!
