Powerful and Intuitive Multiband Dynamics Redefined

FabFilter Pro-MB is a powerful multiband compressor/expander plug-in with all the expert features you need, combining exceptional sound quality with great interface workflow.

With FabFilter Pro-MB, you can get the most out of multiband compression and expansion without struggling to make sense of complicated controls. Professional sound quality comes with a great user interface that helps streamline workflow so you never have to worry about losing time setting up or troubleshooting. Get ready for effortless audio dynamics processing!

A new approach

Instead of conventionally splitting the entire spectrum with crossovers, Pro-MB enables you to directly create a new band at the frequency range you want to work on. Think bands, not crossovers!
The interactive multiband display clearly shows that the rest of the spectrum stays untouched. And if desired, you can easily snap bands together to recreate a traditional crossover system.

Lifesaver and timesaver

FabFilter Pro-MB introduces a unique Dynamic Phase processing mode. It has virtually the same frequency response as traditional multiband processing, but doesn’t introduce latency or pre-ringing, and only introduces minor phase changes when the gain actually changes. Of course, we have also included an excellent Linear Phase mode and a traditional Minimum Phase mode.
The powerful combination of high-quality processing, optimized workflow using the interactive multiband display, and all the expert features you need, make Pro-MB both a lifesaver and timesaver!

FabFilter goodies

Of course, you also get all the usual FabFilter goodies: perfectly tuned knobs, MIDI Learn, Smart Parameter Interpolation for smooth parameter transitions, an excellent help file with interactive help hints, SSE optimization and much more!

All Plug-ins Updated with Bug fixes

Feb 13, 2024

Added support for automatic VST2 to VST3 migration: this enables Cubase 13 on Apple Silicon computers to load existing sessions with VST2 plug-in instances, replacing them with VST3 ones. (Note: this is a relatively new feature in VST3 and not all hosts support it.)
Fixed a bug that could cause Twin 3 and Pro-R 2 to lose preset favorites information after a minor update.
Fixed an issue in the CLAP plug-ins that could cause some controls to not work correctly (e.g. the solo button in Pro-Q 3).
Minor bug fixes and improvements.

Update: All FabFilter Plugins Updated, Pro-Q 3 & Pro-L 2 get Dolby Atmos AAX support

July 5, 2023 – See Update information on our news blog

All Plug-ins Updated – AAX Apple Silicon support

March 21, 2023

Added Apple Silicon support for all AAX plug-ins.
All Pro and Creative plug-ins now support interface scaling. The resize button in the bottom right corner of the interface now offers a Scaling submenu, with options to increase or decrease the scale of the entire interface, e.g. 125%, 150%, etc.
Reduced CPU spikes on changing oversampling or high-quality mode in Pro and Creative plug-ins.
Added a right-click shortcut menu for the preset button, with Save and Save As options. In Twin 3, this also lets you mark a preset as a favorite.
Added support for MIDI program changes in the VST3 plug-ins.
Timeless 3, Volcano 3, Twin 3 and Saturn 2: Added Show Source Flow option, available via the Add Source ‘+’ button menu.
Timeless 3, Volcano 3, Twin 3 and Saturn 2: Added Auto-Collapse Sources option, available via the Add Source ‘+’ button menu. When enabled, expanding one source interface will automatically collapse the others (the default behavior). When disabled, multiple source interfaces can be expanded at the same time.
Pro-DS and Pro-G: Added support for different interface sizes and Full Screen mode.
Pro-G: Added density spectrum visualization in the side chain filter controller, similar to how Pro-DS shows this.
Pro-L 2: Added Auto-Reset option for loudness metering, available as a toggle option in the Loudness Time Scale menu. When enabled, loudness metering and clipping will be reset every time playback starts in the DAW.
Twin 3: Fixed a bug which caused the main Frequency Offset parameter to be ignored for filters with panning and non-modulated Filter Frequency.
Twin 3: Redesigned options icon in the preset browser to make it more discoverable.
Volcano 3: Fixed a bug that could cause possible clicks or noise when modulating filter peak values around zero.
Volcano 3: Fixed issue where text entry for the peak value in the parameter value display would change frequency when piano display was enabled.
Volcano 3: Fixed an issue in the mono version of the plug-in where filters that were removed in the interface could still remain in effect.
Twin 3: The Arpeggiator Lock parameter is now always disabled for new instances of the plug-in.
Small bug fixes and improvements.

All plug-ins updated, Dolby Atmos support for Pro-Q 3 and Pro-L 2

Dec 13, 2021

All FabFilter plug-ins have been updated with bug fixes and improvements, including immersive audio support in Pro-Q 3 and Pro-L 2. This update is free for existing customers and we recommend everyone to update to the latest plug-in versions. So what’s new?

Pro-Q 3, Pro-L 2:

Extended support for immersive/3D audio channel layouts, now up to Dolby Atmos 9.1.6. Note: AAX only supports layouts up to Dolby Atmos 7.1.2.

Pro-Q 3:

In the surround version of the plug-in, it is now possible to let a curve affect all three front speakers (L/C/R).
The interface will now clearly show that it’s in-band solo mode when loading a session that was accidentally saved with Band Solo enabled, or when toggling solo via a Pro Tools control surface.
The interface now restores the previous zoom level when closing and reopening.
The interface now remembers the previous manual threshold value for each band when you switch between auto and manual mode.
Added Use Accessible Colors item to the Help menu, toggling to a brighter color for spectrum collisions.

All plug-ins:

Improved rotational drag mode for knobs to avoid unexpected sudden changes.
For newly installed plug-ins on Mac, factory presets will now be saved in the user’s Documents folder, in FabFilter/Presets.
Fixed issues with text input for controls when running in Pro Tools, on macOS Big Sur and Monterey.
Improved Full-Screen mode on Mac when using multiple monitors: the menu bar and the dock will now remain visible on other monitors. Fixed an issue with Timeless 3 and Volcano 3 where dialogs (e.g. Save As for presets) would not show up in Full-Screen mode. The camera area on a 16″ MacBook Pro will not overlap the full-screen area anymore.
Fixed a bug that caused keyboard shortcuts (e.g. the space bar) not to work in Reaper on Windows after using the mouse wheel and not moving the mouse.
The Windows installers now remember the VST2 folder location that was last used.
Pro-L 2: Fixed a small issue with higher oversampling rates (8x and more) wherein some very specific cases, True Peak limiting could introduce a bit more distortion than needed.
Timeless 3: Fixed an issue that could cause a crash when running at very high sample rates, which also caused VST3 validation in Digital Performer to fail.
Volcano 3: Fixed a possible crash when modulating curves routed in parallel.
Small bug fixes and improvements.

What’s new in v1.21?

All plug-ins:

Fixed an issue with text entry for parameters on macOS Catalina.
Fixed occasional crashes on macOS when loading projects in some DAWs (e.g. Logic Pro), related to having PACE-protected third-party plug-ins in the same session.
Fixed occasional crashes in Bitwig on macOS, when opening sessions that contain FabFilter VST3 plug-ins with side chain support.
Fixed interface scaling issues on macOS 10.14 and higher, when dragging a plug-in interface between Retina and non-Retina monitors.
All VST3 and AU plug-ins with now show up in the DAW without the ‘FabFilter ‘ or ‘FF ‘ prefix in their name.
On macOS, all plug-ins are now 64-bit only.
Minor bug fixes and improvements.

The updated plug-ins are fully compatible with previous versions.

What’s new in version 1.18?

Added visualization of the plug-in output level on Pro Tools control surfaces.
Fixed a bug that could cause the plugin state to become corrupt, with the plugin output becoming silent in some very rare combinations of settings and audio input.

All plug-ins

Updated plug-in for full compatibility with Mac hosts built specifically for macOS 10.14 (Mojave), such as Logic Pro 10.4.4, running under macOS 10.14.0 or 10.14.1. Previously this could lead to an all-black plugin interface.
Improved the way settings are saved when multiple plug-in instances are open to make sure the last setting that was chosen is saved correctly for new instances.
Added support for 300% scaling on 8K displays (High DPI) on Windows.
Fixed an issue that could cause incorrect scaling of the plug-in interface in Cubase 10 or Live 10 on High DPI displays in combination with certain graphics drivers on Windows.
Added a Refresh item to the Options submenu of the presets menu: this makes it possible to manually refresh the menu (and any V1/V2 Preset Folder submenus if available).
Fixed a bug on Mac that could cause program changes received by one plug-in to be forwarded to other FabFilter plug-in instances.
Various minor bug fixes and improvements.

What’s new in version 1.17?

Fixed a bug that could cause the output to become silent in some rare occasions, when using 4x oversampling.

All plug-ins:

Fixed possible crashes in Logic Pro X, which occasionally tries to initialize plug-ins with invalid/uninitialized buffers.
Fixed possible crash in Nuendo 7 on macOS when closing a plugin.
Fixed issues with key stroke stealing on Windows when using the Avid S6 control surface.
Fixed incorrect appearance of plug-in interfaces in Live 10 in High DPI mode.
The VST 2.4 plug-in will now automatically adapt its channel layout to match the audio/track it is placed on. Note that the separate “(Mono)” version of the plug-ins are still included for backwards compatibility.
Fixed a bug that could cause a crash when moving the mouse over the right edge of a menu with icons.
Small bug fixes and improvements.

What’s new in version 1.16?

Pro-C 2, Pro-DS, Pro-G, Pro-MB, Pro-Q 2: Added a workaround for a bug in Ableton Live that caused latency compensation to work incorrectly when loading a session that sets the parameters such that the plug-in doesn’t have latency, in combination with a default preset that does introduce latency. This only occurred with the VST plugin format and caused Live to use the latency from the default preset.
Improved Avid S6 page tables mappings in the AAX plug-ins, now more closely following Avid’s conventions for a better workflow.
