I've tried the 1.3.5 version yesterday night on a windows 7 x64 system with Reaper x64, and so far I must say: this patch seems to have solved every minor gripe I had about VCC! I was still using 1.0.5 before this, because I was hesitant to update. Things were working as they should: I had no crashes, and I used it on every project I did since I bought it, so I didn't dare touching it.
There were 3 issues I had with the old version though. First of all was that it just takes quite some CPU power to use it across a project with many tracks. That's just the nature of the beast. So the major cutback in CPU power was absolutely welcome.
Another issue was that, eventough the old version already worked fine in my x64 setup, it had that annoying problem in Reaper where plugin-windows that are bridged float and stay open after you close the fx window. Not that I blame VCC for that, but since I have that plug on every track, it really adds up after a couple of hours. With the update, it is integrated in the fx screen nice and tidy. Beautiful!
The last thing was the lack of auto-hiss removal on silent tracks. It didn't bother me that much I must admit, but it's just nice to have the option. The cool thing about mixing ITB is that you can go completely overboard with the amount of...well, everything you use. But if I like to have a 100 piece orchestra on 100 channels, and I add VCC to all of those, the noise starts to add up ofcourse. Not that I ever did that, but if I want to, now I can
About the plugin itself: man, I love it! The difference in A/B comparissons may sound subtle, but the effect this thing has on my mixing-sessions isn't subtle at all imo! I notice myself using a lot less processing on tracks eversince I started using it. Not because things sound vastly different when switching it on (that would make it a bad plugin imo!), but because things just seem to fall into place much earlier. The best way to describe my experience with it is this: while mixing without VCC, I feel like the individual tracks are living a life of their own. When I put VCC on every track and the mixbus, things suddenly seem to work together in a context. It's like comparing a collage to a painting.
Now don't get me wrong: you still have to EQ, compress, and whatnot to make the mix sound great! But to me, this process has become a lot more creative and fun, thanks to a single, easy to use plugin.
I know this makes me sound like a salesman, but I just really love it that much ^^
