In X3c I have a T-racks Brickwall Limiter on my Master that goes to my Audiobox 22Vsl mains (master). The levels at 0.0 are hot and causes distortion.  OtherBrickwall limiters do the same, and the mains are not being limited.  In X2 with the same settings, and project files the mains will be limited to what I set on the Brickwall limiter,  -.3  I also tried a Focusrite 2i2 with the same results. Anyone getting this?

First I would lower my level. Than I would check that all tracks are going to a master buss that has a limiter on it for stopping the odd over. I would also invest in the CW Concrete Limiter for Pro Channel and use it. 
 
I would also look hard t the mix and its levels. 

I found it.  The Bass track was going to the Mains, and not to the Bass Bus.  I thought I checked all that because I found that I sent my Brass to the Bass bus, and not to the Brass bus.
 
Thanks!
