All the tone of a complete analog mastering desk in one very simple-to-use plugin
A novel creation from Brainworx founder Dirk Ulrich, bx_masterdesk gives you a complete high-end analog mastering system inside of a single plugin. It is designed to be so easy to use that even inexperienced musicians can quickly dial in great-sounding masters using tastefully curated chains of some of the best-sounding mastering processors available.

Amazing models of top-tier mastering gear in an incredibly intuitive layout
Containing every component you need to create professional-sounding results, bx_masterdesk allows you to master your own material with a minimal learning curve—even if you are not a professional mastering engineer! With a clearly defined 3-step workflow and a pre-tuned processing chain, the entire mastering process becomes extremely intuitive.

Persuasively professional masters in 60 seconds?
Believe it or not, but bx_masterdesk can help you churn out high-quality masters in under a minute. It’s just a matter of toggling through the carefully crafted presets to get you in the ballpark, and sweeting things further with a few key dials if desired like “Volume”, “Foundation” and “Tone” to perfect your sound. Whether you’re a musician, engineer or producer, bx_masterdesk will help you get to where you need to go quickly.

A simple 3-step process for great sounding masters
First, decide how hard your music will hit the processing chain of bx_masterdesk with the “Volume” control. Use the Dynamic Range VU meter to help you adjust your loudness and find the sweet spot for a master that sounds loud without sacrificing quality. Then, use the “Foundation” control to adjust the overall tonality of your mix between lows and highs, setting a nice bass foundation to build your master upon. Finally, adjust the “Tone Stack” to fine tune the vibe of your master. After this, you can tweak even further if desired by adjusting the mastering de-esser, compressor mix and stereo width controls for masters that truly shine.
