Easily master your projects with three simple controls — Volume, Foundation, and Tone

Get results in seconds that rival those from a professional mastering studio

In three quick steps, the bx_masterdesk Classic plug-in will give you a professional-sounding master. First, turn up the Volume control. Next, set the Foundation knob to adjust the low end, and finally, tweak the Tone knob to season the source to taste. Refine even further with one-knob solutions like Stereo Enhance to add width, and THD to inject grit and character.

Visual Feedback

Visual Feedback

There's a fine line between making a master loud, and overly squashing its dynamic range, and with many of the mastering plug-ins on the market, it’s easy to overdo it. But thanks to the large, centrally located Dynamic Range meter on bx_masterdesk Classic, you can always keep a watchful eye, so you’ll know to apply just the right amount of loudness.

This plugin from Brainworks is FREE. What's the point having the paid Uad version? Can't really get the point of this.

Nice and simple

I use it last in the mastering chain as a smart and flexible limiter. I'm very happy with it.

New Fave Tracking Processor !!!

74 bucks, Hmm .. so i give it a try, ( i have other mastering tools, and was looking for unobtrusive tracking compression ) AWESOME !!! i put this after my Fender '55 Deluxe Tweed Plugin, and Presto, the amp plugin is way more flexible now...
the bx_masterdeck Classic gives me a simple one stop Dynamics and EQ section that makes the 5E3 Come Alive !!! and it's so simple, i can spend more time tweaking the Amp.

Simple and good!

Nice simple plug-in that helps you in a few seconds to make some raw-demo masters for your customers, artists and musicians. Make it loud and use stereo expander! Unfortunatelly ther`s no Mono Maker Lo HZ feature for this "classic" edition. But it`s much cheaper than full version. 4+ plugin for sure

The final stage!

At the end of my work, I need an easy to use a mastering product and this is it! Mainly used after my ATR 102. Sparkle and spaciousness in one plug in, love it!

Simple and Sounds Great

I finish most mixes with this following an ATR-102. Tightens up and gives a little tonal tilt where you need it. High value!

Let me preface this by saying I'm a songwriter that needs to create reasonable work tapes for my publisher to review prior to an official demo recording. I am not an engineer and prefer easy to use plugins with great presets to get the sound I need. i.e. live recording either guitar or keyboard with vocals, presets to get the sound I'm after without too much tweaking, then a quick master with BX Masterdesk Classic. I do own quite a few UA plugins but only write a glowing review about a few of them...this is one...

With everything mentioned above, this is exactly what the doctor ordered! Such a simple way to get an unpolished master for my work tapes. So easy to use which is what I need!

Incredible results in seconds, compression adds tremendous spatiality,
its stereo image adds spaciousness like no other plugin. i love it.
