Update: Beta8 brings fixes for Linux problems. I tested it on arch/debian systems with KDE/Gnome, with Reaper & Bitwig. People reported it also works in Renoise, Waveform. I've also added Install Guides for all guides because the plugins are not signed on macOS, don't have an installer on Windows and need some additional libs installed on some Linux distros. Let me know how it works. I have already many feature request and ideas ready to implement! All downloads on the https://polarity.productions/polarity-md page!

What the heck is Polarity-MD??

I've just released Polarity MD, a completely free multiband dynamics plugin that I've been working on for a few weeks. It features four bands of upwards and downwards compression, individual clippers on every band, and works across all major systems and plugin formats. I designed it to be easy to use, visually intuitive, and to sound great right out of the box whether on your master or drum bus. Please give it a try, share your feedback, and I'll keep improving it based on your suggestions.

Polarity MD is a new free plugin for multiband dynamics processing, focused on four bands with both upwards and downwards compression and built-in clippers for each band.

Available in multiple plugin formats: VST3, CLAP, AU, and soon LV2, and works on Windows, macOS, and Linux.

Designed with ease of use in mind: no account required, no telemetry, no licensing restrictions, always free to download and use.

Unique feature set includes four bands (instead of the typical three in OTT), separate input/output clippers, and visual color coding for compression and clipping feedback.

The entire backend is coded in C++ with JUCE, and the graphical user interface uses HTML and CSS for cross-platform compatibility.

Optimized for master buses and drum buses, designed to make tracks louder while providing detailed visual feedback.

Preset options for typical mastering and mixing use-cases, including common crossover frequencies and band setups.

Currently in beta: users are encouraged to test, report bugs, and offer feedback or feature suggestions for ongoing improvements.

Some issues are known, especially on macOS with plugin signing and format compatibility, but most major DAWs and systems are supported.

The visual look is still evolving, with upcoming design improvements planned through collaboration with a professional designer.

I Built a Better OTT Plugin: 4-Bands, Built-in Clippers, and 100% Free

In this video, I’m excited to show you Polarity MD, a plugin I’ve been developing over the last few weeks. It’s essentially a four-band "OTT" style multiband dynamics processor that I built because I wanted more control than the standard three bands. It features upwards and downwards compression on every band, plus integrated clippers on the input, the output, and each individual band. It's completely free, and runs on Windows, Mac, and Linux. I also walk you through my unique approach to the GUI, which I built using HTML and CSS to ensure it works across different systems.
