I feel your pain there Don. However, Waves 9 is way better than any other version I've used in Sonar since Waves 6. Yeah it's not cool we can't use Xray and the side-chaining thing doesn't work, but to me that's pretty miniscule compared to what you can do with those plugs.
I don't use side-chaining because, well, not to sound like a dik, but I have always considered it cheating. I can make my instruments work without that so it doesn't bother me in the least to not have that function with the Waves stuff.
As for Xray, I just create screen sets and have them dock. This wayI can work and still have my plugs visible. Maybe not a fix for you, but it works for me.
As for the quirky movement, move the knobs slow and they respond perfectly on my end.
Eventide: You can't blame that on Sonar really. If they didn't test it in house using Sonar, that's Eventide's fault, is it not? It sucks you're in that situation and it also sucks that some companies don't feel Sonar is popular enough to test on. Look at me man....I got a UAD 2 card here that won't work right with their latest update due to not having tested it extensively in Sonar. They used to before...but all of a sudden just decided not to.
At the end of the day bro, it's cut and dry. You either get the results you want out of a DAW and your plugs or you just move on to something else, ya know? I know sometimes it feels good to vent...I've done my share as well..lol...but it doesn't seem to do any good. So if you ever feel like your back is against the wall, as much as it pains me to say it, there are other DAW companies out there interested in your business. I use Sonar every day and it's my favorite DAW quirks and all. However, if there is something that I want to use where it may not be possible in Sonar, I have several other DAW's to turn to. Unfortunately, that's just the nature of the beast with this stuff I'm afraid.
