OneZero Samples is a sample and preset pack label founded by Sam Barnes, who produces under the alias Serpnt and is one half of the drum & bass duo ZeroZero. The label launched in November 2023 and focuses on the deeper, darker side of the drum & bass and bass music spectrum, releasing material aimed at producers working in jungle, minimal D&B, and underground bass styles.

The catalog includes drum, bass, FX, and synth sample packs alongside Serum preset banks, with releases distributed through Bandcamp, Loopmasters, Loopcloud, and Producer Loops. Notable titles include the OneZero Samples Taster Pack, Modern Jungle Rollers, and the ZeroZero 101 D&B Serum Presets bank, plus collaborations with producers such as Brain, S.L8R, Euphonique, Dunk & Acuña, and Trex & Teej.

The label's stated design philosophy is to deliver sounds that are usable straight from the studio while leaving enough room for producers to shape and re-process them, rather than fully finished loops. Packs are royalty-free and target electronic music producers building original tracks in their DAW.

OneZero Samples has 28 products cataloged on Equipboard, including Drum and Bass - General, Jungle, and Liquid.
