This Plug-in Makes Multiband Compression Easy

FabFilter Pro-MB is a robust multiband compressor/expander plug-in with all the expert features you need, combining exceptional sound quality with great interface workflow. At Sweetwater, we take compression seriously - so seriously, in fact, that many of us use multiband compression on a daily basis. Now, granted - it's a powerful tool with a reputation for being notoriously difficult to set up and control, but FabFilter has jumped the learning curve with Pro-MB's intuitive, user-friendly interface that lets you effortlessly conquer the beast.

FabFilter Pro-MB Compressor/Expander Plug-in at a Glance:
  • Think bands - not crossovers!
  • Multiple compression modes, for superior results with minimum fuss
Think bands - not crossovers!

As opposed to splitting the entire spectrum with crossovers - the way most multibands work, Pro-MB lets you directly create a new band at the frequency range you want to work on. Easy peasy! The cool multiband display clearly shows the rest of the spectrum as untouched. And if you so desire, you can easily snap bands together to re-create a traditional crossover system. Naturally, you also get the usual packet of FabFilter goodies, including precision-tuned controls, MIDI Learn, Smart Parameter Interpolation for smooth parameter transitions, and more.

Multiple compression modes, for superior results with minimum fuss

FabFilter Pro-MB features a unique Dynamic Phase processing mode with the same frequency response as traditional multiband processing, but it only introduces minor phase changes when the gain actually changes - without any latency or pre-ringing. Pro-MB also includes a highly effective Linear Phase mode, as well as the traditional Minimum Phase mode. Take it from us, the potent combination of high-quality processing and juiced workflow using Pro-MB's interactive multiband display and expert features is going to make you a multiband compression wizard.

FabFilter Pro-MB Compressor/Expander Plug-in Features at a Glance:
  • Up to six processing bands, freely placed anywhere in the spectrum

  • Unique Dynamic Phase processing mode featuring zero latency, no static phase changes and no pre-ringing artifacts

As useful a tool as I have used

Like the title says, this is an amazingly useful tool. From tightening up the lows on a bass, punching up a kick, controlling a splashy hat, or getting an acoustic to sit right under vocals, etc etc etc, Pro-MB makes it easy! I have yet to plumb the depths of all the functionality (and there is a ton of it), but straight out of the box, it was easy to use and understand. Added bonus, it sounds very natural even when pushed hard. It can be hard to justify plugin purchases sometimes, but not with the Pro-MB, I find myself tackling issues I would have never though to use a multiband comp for. Happy!

Whoa..

I have this and the Fab-Filter Pro Q.. With these two plugs, you can do some serious shaping with basically no coloration and definitely no artifacts. If you're running your signal through thousands of dollars of hardware, why color your sound or risk artifacts with plugins that cost a few hundred? Seems weird to me... Unless you use the UA plugs.. Anyway, the Pro-MB might be the most versatile plugin on the planet right now... If it cost $400, I would've bought it.. Seriously. It makes other multiband compressor plugs look like toys.. Think of it as a dynamic EQ with wings, a jet engine and stealth capabilities.. I've used it the most on acoustic guitar and vocals.. The things you can do with this on acoustic guitars is almost mind blowing. You can basically flip a guitar inside out.. Take the weakest part and make it the focal point.. Drive subtle harmonics to the surface and calm the brightest string strikes... Even enhance the stereo image.. Again, with no noticeable coloration and definitely no artifacts.. If I could only use one plugin the rest of my life, it would be a coin flip between the Pro-MB and Lexicon reverb plugs.
