Lo-fi Drum Loop

How it's made

Source

a sampled-style drum kit played on a lazy 90 BPM grid. Kick: a damped sine whose pitch falls from ~140 Hz to ~46 Hz in 0.2 s plus a 30 ms low-passed thump. Snare: two shell modes (~210 and ~330 Hz, 60–90 ms) under a band-limited noise rattle (0.9–4.8 kHz, ~170 ms). Hats: 6.5–10 kHz noise, 25–45 ms closed and ~200 ms open.

Body

kick and snare are soft (no hard beater click); snare ghost notes sit 11 dB below the backbeat. Everything passes a master low-pass (1.5–9 kHz) with a slow sweep and gentle tanh saturation, like tape or a dusty sample chain.

Rhythm

3 bars of 4/4 at 90 BPM = 8 s, so the loop holds whole bars. Kick on 1 and the swung "and of 2", snare on 2 and 4, hats on the 8th and 16th grid; off-beat steps are pushed late by the swing amount (up to a triplet feel) and every hit is nudged by a few ms of human timing error.

Dust

sparse vinyl crackle (high-passed impulses, 1.5–9 kHz) over a faint low-passed pink hiss bed.

Variation

`rng` varies velocity, pitch, noise colour, timing and pan per hit; later bars add syncopated kicks and ghost snares as the groove amount rises.
