Just checked this morning and the Roland guys must have pulled a weekend shift. Most Roland drivers are updated and ready to go.

Sorry, here's the link!

I have mine working with the hack (and my PCR-500 keyboard).

I just got thru upgrading 7 to 10 and all went well. I had to do the famous re-registration of XLN products but other than that all has gone VERY smoothly. STUDIO-CAPTURES went right on line with a noticeable reduction in latency. What use to run in 256 now runs at 128 with no problems so far.
