As I'm still waiting for the 2600V to arrive by mail I went back to the demo, downloaded and installed the fix for Leopard patch and some things have improved and do seem to be working in PT8. At a quick glance cpu usage seems better, no noises and unwanted glitch when used with 4 processors selected...BUT....the VCO 1 controls are all surrounded with individual yellow rectangular boxes so it seems there's GUI problems. This is just at a quick glance...I'll be going over it with a fine comb over the coming days.
