The compressor from the future.

The elysia• mpressor plug-in for UAD-2 and Apollo interfaces is a creative tool that offers punchy sounds with beautiful coloration, as well as more extreme processing options.

Developed by Brainworx, the mpressor plug-in is an exacting emulation of the high-end, Class-A hardware, perfectly capturing its unique features like gain reduction limiting, anti-log curves, and negative ratios.

Apply extreme compression effects without degrading the original sound

Use the Auto Fast function for fast, distortion-free compression without any artifacts

Harness the Niveau Filter to change the character of a track from subtle to striking with continuous frequency shift

Punch up flat or dull drum tracks

Key Features

100% Discrete Class-A Sound: Faithful recreation of the elysia• mpressor's all discrete circuitry and special character, authenticated by elysia• GmbH
Powerful Creative Compression: An outstanding universal compressor as well as an inspiring dynamic effects machine that produces fat and freaky sounds with maximum punch, beautiful colorations, and extreme processing options.
Auto Fast: The compressor can be very fast, but only when it is really needed. Auto Fast shortens the attack time automatically on fast and loud signal impulses.
Anti Log: If intentionally striking and creative compression is the goal, it definitely makes sense to turn things upside down. Anti Log provides an alternative characteristic of the release curve following an anti-logarithmic course. With Anti Log you can create many exceptional compression effects just by the push of a button.
Negative Ratios: The characteristic curve bends and goes back down! Heavy pumping, backward sounds, etc. Perfect for cool compression effects.
Niveau Audio Filter: Easy to use, yet very flexible, the Niveau Filter's main function is to change the proportions between high and low frequencies. By simultaneously boosting and cutting the selected frequency areas, it is easy to influence the character of a track ("bright" vs. "dark").
Gain Reduction Limiter: A specialty of the mpressor. This limiter is not placed in the audio path where you would usually find it, but in the control path of the compressor. Choose the maximum amount of gain reduction you want to allow at the twist of a knob.
Mousewheel Support: The controllers of the mpressor can be moved with the mouse wheel.

love it!

I didn't expect this to be my current favorite comp in my voice chain for my radio show - just try the "Well Defined" preset and hear what it does to your voice!

Unfassbar flexibel

Der mpressor bietet nahezu unendlich viele Soundvarianten durch super Schaltungen und nicht zuletzt durch die den EQ. Bisher macht er auf allen Audioquellen einer super Figur und auch interessante Sounddesigns lassen sich erstellen. Er macht einfach Spaß!

very goood and universal tool

fat and flexible. one of my favorites on tracks. the reason i give 4, not 5 stars is absence of mix/dry knob. that knob would make this compressor iconic.

Impressive compressor

So good that I bought the hardware.
The Swiss knife compressor, excellent on guitar, piano, Rhodes, Bass and even on the orchestra and certainly on other instruments.
I don't use it for sound design but with low ratio with 4 or 6 db of gain reduction with "GR Limit" at 4 db and a subtitle "EQ Gain".

"Et voilà", my favorite compressor

Underrated brutal compressor!

This compressor can be seriously fast. I love it for clamping down and distorting drum transients in parallel. The release times can also be very fast, but the curves are always musical. The negative ratios and exp release offer more creative sounds which can be fun too.

There is some aliasing when using more extreme settings, but I really couldn't care when it sounds as great as this plugin does!

The Elysia.mpressor is a great tool to give drums much more power.
It also has very useful functions for creative sound design, (e.g. the eq gain/freq knobs).
