Just 4 Kicks makes its AI drum sounds before you ask for them

Pressing Generate in Just 4 Kicks currently asks an online database for a sound that already exists. In an engineering note updated this October, maker Just 4 Noise says it prepares AI-generated kick-drum hits ahead of time, then matches each request to one of them.[1]

The product is sold as a €79 one-time purchase. Its current page describes controls for choosing and shaping a kick, plus MIDI playback and WAV export. For a musician building a drum part, the useful distinction is between obtaining the starting sound and editing the sound that arrives.[2]

A prepared sound, followed by hands-on shaping

Just 4 Noise says it removes a hit from the pool after use and replenishes popular parameter combinations first. It acknowledges that unusual combinations have a smaller supply. A version that generates locally inside the plugin remains a future plan.[1]

For a producer, the useful question is whether an unusual setting gives enough variation to find a sound worth keeping. An interface can make exploration easy without answering that musical question.

The current FAQ describes real-time generation. The October engineering note provides the more specific mechanism: selection from a prepared pool. That timing matters when assessing what the product delivers.[2][1]

What the online requirement means in a project

The published requirements are Windows 10 or later, or macOS 15 or later on Intel or Apple silicon. The plugin comes in VST3 and AU formats; AAX and Pro Tools support are described as forthcoming. Internet access is required for obtaining new kicks. The site offers a trial, allowing those requirements to be checked before purchase.[2]

A sensible working sequence is to settle on a candidate, shape it against the rest of the track, and save the exported audio with the project. That file captures the choice already made.

For an illustrative listening check, use a short section containing both the bass part and the kick. Compare a shorter and a longer decay while keeping the musical passage the same. Listen for the attack, the tail and how the drum supports the bass. The objective is a usable part in a song; generating more candidates is only a means of getting there.

A sound licence has a different job from a uniqueness promise

The terms dated 15 October permit royalty-free commercial use of the output in music, films, games and other creative work. They prohibit selling or distributing that output as a standalone sample library or similar product whose main value is the generated audio itself. They also preserve the licence for output made before an account or agreement ends.[3]

An exact-file exclusivity promise says little about how distinctive a kick will sound. For a producer, those are separate considerations: permission to release a track, access to the chosen file, and whether the result has the character the music needs.

The contract also addresses service continuity. If the instrument is discontinued, Just 4 Noise promises reasonable efforts to provide an offline update and advance notice. It explicitly qualifies those commitments in an insolvency. A perpetual software licence therefore should not be read as an unconditional promise that the present online delivery system will always be available.[3]

The lasting result is the drum part that survives that process and earns its place in the finished track.
