Multiband compression and expansion are powerful tools, but notoriously difficult to set up and control. Enter FabFilter Pro-MB: make multiband dynamic processing intuitive yet powerful at the same time.

A new approach

Instead of conventionally splitting the entire spectrum with crossovers, Pro-MB lets you directly create a new band in the frequency range you want to work in. Think in bands, not crossovers.

The interactive multiband display clearly shows that the rest of the spectrum remains intact. And if you wish, you can easily join the bands to recreate a traditional crossover system.

Lifesaver and time saver

FabFilter Pro-MB features a unique dynamic phase processing mode. It has virtually the same frequency response as traditional multiband processing, but introduces no latency or pre-ringing, and only introduces minor phase shifts when the gain actually changes. Of course, FabFilter has also included an excellent linear phase mode and a traditional minimum phase mode.

The powerful combination of high-quality processing, an optimized workflow using the interactive multiband display, and all the expert features you need makes Pro-MB a lifesaver and a time saver!

FabFilter gifts

Of course, you also get all the usual FabFilter advantages: perfectly tuned knobs, MIDI learn, smart parameter interpolation for smooth parameter transitions, an excellent help file with interactive help suggestions, SSE optimization, and much more.

Features

• Up to six processing bands, freely placed anywhere in the spectrum
• Bands can be easily joined to form a traditional crossover system
• Handles any form of dynamic processing, from highly transparent compression, limiting, and expansion to pumping upward compression and punchy gating
• Unique dynamic phase processing mode with zero latency, no static phase shifts, and no pre-ringing artifacts
• Excellent linear phase processing mode, which eliminates audible artifacts when quickly changing crossover frequencies
• Minimum phase processing mode
• Linear phase oversampling up to four times
• Fully customizable per band: threshold, range, attack, release, output gain, ratio, variable knee, lookahead (up to 20 ms), variable stereo linking, mid- or side-only processing, external sidechain input, triggering in a frequency range
• The slope of each crossover can be freely adjusted between 6 dB/oct and 48 dB/oct
• Smart attack and release curves, highly dependent on the program and frequency
• Global dry/wet mix from 0% to 200% to easily scale the overall effect of the plugin
