Simply awesome and simple easy operation. I use this on my master channel sometimes and on my drum channels. I can get things nice and loud without any distortion and is very CPU friendly.
The bx_limiter is an extremely powerful tool. I love that it's transparent even at the extremes.
I love this limiter because it does so much more than just standard peak limiting. The channel link, parallel and saturation features make this one of my most effective and favorable tools for handling dynamic control across multiple busses.
The best feature on the bx_limiter for me is the XL -- you can just get that little bit more out of it.
