I don’t know… I only know what’s been working for me right now! I wasn’t consistently experiencing the issues UA reports on their web page; my situation had more to do with the Satellite hardware unit losing its connection with N6 (it also happened to some extent in N5). Was mysterious to the point that I worked pretty hard with a couple of guys over at UA to try to identify the source. After we’d discussed everything there was to discuss, and I’d spent a couple of weeks attempting to identify the various conditions, I sort of gave up and switched over to 32-bit… and everything’s been fine ever since. Most problematic was UAD in combo with iZotope RX’s plugin spectral editor.
I am using the latest UAD software, and since I’m in 32 bit, no bridge. It’s all working great.
BTW… I was also very much looking forward to using 64-bit, sampler-wise. I was unhappy about going back to 32-bit, but had no choice. Again, looking forward to when everybody finally gets this stuff figured out.
