OK, let me really try your patience:
I don't understand, that link takes me to the "what's new" page.
Is it a separate installation or is it in Sonar 2017.05?
 
Thanks again,

Should be a separate installer in the SONAR Platinum group. Here is an image I made some time ago for a thread about the Boutique FX Suite that shows installers under SONAR Platinum in the installed state

If you do not see the Engineering FX Suite in the Command Center contact support. If you see a red indicator instead of a green one, the package has not been installed.

Hmmm, I guess I need to contact support then.
 
Thanks everyone,

Sonar is up to date and engineering suite is up to date but I cannot find the Adaptive Limiter! Any ideas?

Under vst3 effects. Did you rescan?

interpolated: Thanks! Yes, that was it!

This plug in seems to (at least) sometimes generates unintended fade in?
One of my project strangely fades in the first note of song when mixed down, I tried anything I can think of, and I noticed this issue happens when signals pass Master Bus.
Then I replaced Adaptive Limiter on Master Bus, all turned well.
I didn't test what settings cause this problem, but I don't use what does like this unless it fixed.

I've used AL both for mastering and mixing and here are my results.
 
For mastering, this is maybe the best limiter I have.  It works as advertised with as much or as little transparency as you want.  However, for mixing a different story.  I set the look ahead to minimum and inserted it on two tracks in a  song with two acoustic instruments and one instance of Rapture Pro and one instance of Z3ta +2.  The latency on my converter was set to 256 samples which typically is more than enough for 4 tracks, but I got dropouts galore, and my CPU meters were jumping all over the place.  I replace AL with Waves L1 Ultramaximizer and the problems disappeared.  I repeated this procedure several time with the same results.
 
For now, I'll stick to using it for mastering, and I'll wait to see if any changes are made to it before using it in mixing.

I agree 100% I am preferring it over Slate FGX on my master bus. So far I am loving the Adaptive Limiter in Sonar!

I used it last night to add a bit loudness to an old project. I find myself reaching analogue bus compression before any limiting these days. By analogue I mean virtual although given the opporchancity I would do it through a console.

I've tried it - looked very promising. Each time I get maybe half way through a tune and start getting pops/audio artifacts.
Replacing AL with the BT BrickWall limiter and the artifacts vanish.  I have a friend who had a similar experience.
Any idea what might be causing the artifacts?
