I love the bx_control, not only because it is such a quick and handy tool for monitoring M/S when I'm mixing ITB, but also because it's an immediately effective way to both tighten and widen something in the mix.
I just wanted to tell you that I was blown away with the Brainworx plugins! I can't remember the last time I got a smile from ear to ear when I started tweaking the parameters of a plugin. I think your design is extremely well done and it shows a visionary type of attitude that I appreciate.
bx_control is the first plug-in on my master channel and is an essential part of my monitoring section when mixing or mastering in the box.
I always use this to control my mono signals. Where I have stereo bass, I can just dial in the amount of mono I want so the sub and hard hitting stuff stays in the mono area and the tops go to the side. I use this daily.
Brainworx bx_control offers the best stereo control of any plugin I own. I use it as a utility to both widen and constrain the stereo field and I consider it indispensable when mixing down a track.
The metering and soloing options alone on this plug are worth it. But it doesn't stop there: Mono your bass frequencies or widen your top end with all the enhancement features. Your mixes will be clearer and more focused with little effort.
As the whole world goes M/S, this little beauty is an essential blade on your production knife.
