About Knock Audio KNOCK
KNOCK comes from DECAP, an ARIA Platinum producer whose drum work has landed on tracks for Kendrick Lamar, Beyoncé, Bad Bunny, and dozens of other Billboard-charting artists. Before this plugin existed, he built a reputation through Drums That Knock, a sample pack series that’s shaped a chunk of modern hip-hop and pop production. KNOCK takes the processing chain behind that signature sound and puts it in a single plugin.
It’s built for anyone whose drums feel thin or buried in the mix, which is most producers at some point. Beginners who don’t know how to make a kick punch through a busy arrangement, and working engineers who just want DECAP’s specific processing without rebuilding it from scratch every session, both land on the same tool here. It’s designed to be usable immediately, not something that takes a manual to figure out.
The plugin runs 3 core modules on a drum bus or individual hit. A transient shaper adds Punch, amplifying attack to make a hit snap instead of thud. A saturation stage adds harmonic distortion across 3 selectable modes (soft, medium, hard) while compensating for perceived loudness, so cranking distortion doesn’t just mean cranking volume. And a sub generator detects when a kick is present and layers a tuned sub-frequency tone underneath it, with adjustable pitch, useful for breakbeats or for tuning a kick to match the key of a track. A bypass toggle lets you A/B the difference instantly while a loop is playing.
KNOCK runs as a 64-bit VST3, AU, and AAX plugin, supported by every major DAW, and it comes bundled with factory presets built by DECAP himself. It’s also available as a mobile app for iOS. A free trial gives full access to test it before buying, and Knock Audio also sells it bundled with the entire Drums That Knock sample library (9 volumes) plus KNOCK Clipper for anyone who wants the complete processing chain and sound source in one purchase.
