From the masters of mid-side processing, bx_rooMS is a breathtaking reverb and the next frontier in simulation of acoustic spaces and mechanical plates.

At its core, it features tons of realism, superb sound quality, and a huge collection of virtual rooms, halls, churches, plates and ambience. But bx_rooMS also empowers you to shape your virtual spaces in unusual and extremely powerful ways, adding mid-side parametric filtering, center-image panning and width control of the reverb's stereo field.

The key to bx_rooMS' realism and versatility lies in its embedded TrueSpace technology, which explodes the number of included reverb algorithms to create a virtually infinite number of room sizes and shapes. While currently available reverb technologies emulate a fixed set of space types, such as Room, Hall, Church etc. (often called algorithms) and then offer a limited range of possible sizes for each of them, TrueSpace provides a continuous range of unique space types (or algorithms) while always making available the full range of possible sizes.

With bx_rooMS, you control the reverb's stereo image. Crank the Stereo Width control for more spacious reverb and bigger-sounding mixes than simple panning can achieve.

With almost 200 outstanding presets to get you started - including patches contributed by expert mix engineers - bx_rooMS offers unique reverbs suited to every music production and genre.

Mid-side processing is unequaled in its ability to transform stereo signals. This reverb is easy enough on CPU usage for you to insert (!) it on many stereo signals and busses, so give your mixes that finishing M/S touch.


  • Stunning simulations of rooms, halls, churches, plates and ambience
  • Quick Select buttons easily produce settings for five different environments 
  • Continuously variable Stereo Width control adjusts reverb field from mono to stereo to super-wide stereo
  • Modulation Frequency and Amount controls add subtle movement or create outrageous, pitch-shifting reverbs
  • Indispensable Fix Mix parameter allows preset surfing without changing wet/dry balance of effect
  • Extremely low CPU drain allows many instances to be used on track inserts across a mix
  • Nearly 200 presets

    I can't speak highly enough about the endless possibilities of bx_rooMS. I tried it on a ballad and it was super transparent sounding and doesn't wash out unless you want it to. To me, it's… Read More

    A great reverb for creating spaces that don't necessarily try to emulate the classic algorithms. With a clean sound that doesn't command too much attention to itself (in a good way!), it… Read More

    Super cool reverb. I like how quick you can dial in and tweak all kinds of spaces. The GUI is super easy to understand and the sound is awesome -- as is expected from Brainworx!

    by Martijn van Dongen
    This is the best reverb I have ever used! Tried so many different ones, from Valhalla to Softube TSAR, they are nice but not always easy to blend in. This one really does!
