First off, I’m not here to bash Master Rig. I think on the surface it should be a fantastic tool. Is there a comprehensive video or manual for these tools? I’m more of a visual learner, so the video would be better.
Any ME’s input on this would be great.
Seems to work fine for what it is. I think Steinberg is trying to emulate Ozone from Izotope. I find it easy to use. Best of luck!
@OP Strange topic title for the question you have. I think it’s very useable, which doesn’t mean a video wouldn’t help.
In my opinion, Master Rig is a great tool. A lot of the supplied presets involve radical changes to the sound but master rig can also be successfully used for subtle treatments. The multi band compression is excellent but it’s sometimes helpful to use only a single band and you can do this in Master Rig. The saturation can also be used in a subtle manner in combination with the EQ to approximate analogue tape saturation effects. The way you can freely change the order of the effects and process mid/side or left/right are also good plus points.
Thanks for the replies. I guess I’m comparing this to Ozone, which I find the limiter more useful. I find that when using Master Rig, it’s not very subtle. The eq’s Q settings aren’t very versatile and the functionality is limiting. I’d like more flexibility in the EQ. . I find it very harsh sounding. I guess the key is to use it VERY sparse. I’ve tried to use it a few times, but end up going back to Fabfilter L and Q. Or the Manley Massive Passive UAD plugs.
I guess I’ll just use Peak Master, which I think I’ve been using for 20 years. 
The master rig adds a lot of great value to wavelab. I hope it’s improved on.
