Too many hoops and limitations, with an impossible support maze.
 
 

They have support?
 
Who knew?
 

I soup hozed.

I love the 88 piano plug but it has an annoying habit of sometimes not fully loading the samples when you load a project. I hated to do it but I went back to my Addictive Keys.

The reason I have it because I bought Ensemble 88 on impulse for $17.  I didn't realize it was PACEd at the time or I would've passed.
 
I do like it quite a bit.  Hopefully I'll manage to get it going on the new machine.

i like the layering. If not, I would have paced too.

I think that the inMusic purchase of SONiVOX and AIR may have disrupted the development and support for those products.  http://www.inmusicbrands.com/
 
If they work for you, and you got them at a good price, well great! I grabbed a bunch at killer prices!
 
But if you have run into any issues or bugs, then it seems that their support has no info regarding future updates or bug fixes.  I contacted SONiVOX tech support about a question for one of their products, and as soon as they saw that I was running Win 10, they closed the ticket and told me that their products do not support Win 10 yet.
 
So, YMMV ...

I bought their Big Bang Cinematic drums, which is currently non-functional in every DAW except Samplitude, thanks to a known problem with the GUI. Sonivox has acknowledged the bug on their forum, and one of their reps said that it is being reviewed by their software team. That was 5 months ago. Since then, nothing. But they still have the product on their site, and it is currently on sale. 
 
I have an issue with a company that will knowingly sell a product that a good number of folks won't be able to use because of a bug they acknowledge is there, and then seem to do very little to try and fix it. 

There is a workaround for the Big Bang crash that seems to work, but yes I agree.

Yeah, I saw the workaround and tried it, but it doesn't work for me at all. BB still crashes Sonar and Reaper, like clockwork, every time I fire it up. The only DAW I own that BB doesn't crash is Samplitude. It's too bad, because BB is not a bad library at all; its got some stuff in it I quite like. I'd use it fairly often if I could get it stable in my main DAW.
