User-Friendly Interface

Inspired by its historical counterpart, the Complexx boasts a logical layout, color-coded for easy navigation.

Whether you’re adjusting compression, expansion, or general settings, the design ensures smooth operation.

A Glimpse into Audio History

The golden era of audio witnessed innovative creations, and one in particular, a revered British dynamics processor from the late '60s, stood out to us.

This unit, which had its origins in the vision of renowned manufacturers of that era, was celebrated for its unmatched versatility. Crafted with intricate transistor electronics, its unique feature was a FET gain-reduction mechanism that was steered by three distinct circuits.

Every detail, from its color-coded controls to its layout, was meticulously designed for intuitive use.

Just fell in love with Complexx

Using Complexx on my drum bus and 2 bus in every mix, since the day I bought it. Love this thing.

Drum bus go-to.

I've owned this plugin over a year and it makes it on my drum bus almost every mix. It adds impact to drums and shine to cymbals. Its soft-knee FET sound is unique and hard to find elsewhere.

Monster of a plugin!

Monster of a plugin, just adds a ton of weight and punch to drums! Highly recmmended!

The ultimate drs comp

If you are after the ultimate drum bus shaping, this is what you need. Easy to dial in breathing, aggressive or smooth drum sound. Also great with individual drum kit pieces.

10hz

Sounds great and is a pleasure to use. One small suggestion: there seems to be a slight boost in the 0–10 Hz range, which can add up when using multiple instances. An optional subsonic/DC filter would be a great addition. Otherwise, it's a fantastic plugin.
