Access Music just released the latest OS for their Virus synth line, which totally rocks. I'm getting ready to install it now so I will let you know how it goes. It's been in beta for a few months so I expect it is stable by now.

Access has also set up a Vimeo channel, including some great jam sessions with their gear from past music events. This is a link to the shorter one if you want to get a sampling of what to expect.
