Plugins That Knock – KNOCK Plugin AU/VST3/AAX

KNOCK Plugin by Plugins That Knock — Drum Processing Built Around Real Results

The KNOCK Plugin by Plugins That Knock came out of a specific need: platinum producer DECAP wanted a single plugin that replicated his drum processing chain without requiring producers to stack a dozen individual tools. The result is a focused drum enhancer with five processing modules — each one doing exactly what its name says, nothing more complicated than that.

If your drums sound flat, buried, or just not quite there, this is the kind of plugin worth reaching for first.

KNOCK Plugin — Five Processing Modules

KNOCK Plugin — Why the SUB Module Stands Out

Most drum plugins add saturation and transient shaping. The SUB module is what makes KNOCK different. Rather than just boosting low frequencies with an EQ, the SUB section actually detects when your kick is hitting and generates a tuned sub tone at a pitch you select. The result is a clean, controlled sub-bass layer that tracks your kick pattern without muddying the mix.

For trap and hip-hop producers, this is the kind of tool that addresses a real problem: getting the 808 and kick to coexist without sacrificing low-end power on either one. Load KNOCK on the kick channel, tune the SUB to your root key, and the relationship between the kick and bass becomes much easier to manage.

Built by DECAP — What That Actually Means

DECAP is behind the Drums That Knock series — one of the most recognized drum sample packs in hip-hop production. The KNOCK Plugin extends that philosophy into a processing tool: the same thinking that made those samples sound right applies here. The factory presets ship with settings DECAP actually uses, which means they’re a genuinely useful starting point rather than demo patches that get replaced immediately.

Why Producers Keep Using KNOCK

Low CPU footprint means you can stack it across kick, snare, and hi-hat channels without watching your performance meter spike. The interface is straightforward enough that you’re not spending session time learning the plugin. And because each module works independently, you can use just PUNCH and AIR on a hi-hat loop, or the full chain on a kick that needs everything.

It also ships with factory presets designed by DECAP — a drum producer who clearly thought about how these modules interact, not just how each one behaves in isolation.
