UK Bass / 140

Syncopated 130–140 drum frame

The kick plays a broken pattern that implies both the 4x4 and the half-time at once; the snare is on 2 and 4 with a clap doubling, and the percussion fills the 16ths asymmetrically.

1. Kick: short and knocky (decay 180–220 ms, fundamental 55–65 Hz), from Drum Sampler with Punch 30%. Keep the sub kick off; the square sub is right behind it.
2. Snare on 2 and 4, with a clap only on 4 in bar 1 and on both in bar 2. Snare short (150 ms) and bright; the clap adds the spread.
3. Conga/tom patterns: Euclidean Sequencer with 5 hits over 16 steps rotated 3, then Random (MIDI tool) at 10% velocity variation. Tune two congas a fifth apart.
4. Groove: MPC 16 Swing 58, Timing 80%, applied to hats and percussion; kick and snare straight. Then move the open hat 10 ms late and the second-bar extra kick 10 ms early by hand.
5. Drum group: Drum Buss with Drive 20%, Transients +15, Damp 10 kHz, then Glue Compressor 2:1 with 1–2 dB reduction. No reverb on the group; room on a send only for snare and percussion.

Square-wave sub riff (Operator with pulse-width-like morph)

Where dubstep subs are sine, UK bass subs are often square: hollow, odd harmonics, audible on small speakers without any saturation. They play short riffs with rests and octave jumps, functioning as another percussion instrument.

1. Operator, parallel algorithm. Osc A Square at 0 dB. Osc B Sine, same pitch, at −6 dB: mixing a sine into the square fills the fundamental (a square's fundamental is relatively weak). Automate B level between −12 and 0 dB for "sub-ness" vs "squareness".
2. Operator filter: low pass 24 dB at 180–250 Hz, no resonance. This keeps the 3rd and 5th harmonics and cuts everything else, so it reads as a bass note, not a buzz.
3. Amp envelope: A 1 ms, D 180 ms, S 0.6, R 25 ms. Riff of 8ths and 16ths with rests; typical shape is a 2-note phrase answered by a rest and an octave jump.
4. Mono, Glide 0, Legato off. Slides are rare in this style; the notes are percussive.
5. Saturator Analog Clip 2 dB for glue; EQ a small dip at 150 Hz if the square's 3rd harmonic clashes with the kick body.

Percussive FM bass stab (Meld Drum/FM engines)

The Night Slugs-style "bass as percussion": a short pitched hit with a fast pitch drop, sitting between kick and tom, playing syncopated patterns. Meld's FM or Drum engines produce this in one device.

1. Meld, Osc A FM engine: ratio 1.5 (a fifth above the carrier), FM index modulated by Envelope 1 (fast decay 60 ms) so each hit starts bright and ends as a tone. Pitch modulated by Envelope 2, −12 st, decay 40 ms, for the "doink".
2. Osc B Noise Flow engine with a 30 ms amp decay, mixed at −18 dB: the click.
3. Per-oscillator filter on A: low pass around 800 Hz with the envelope adding 30%. Amp envelope A 0, D 160 ms, S 0, R 20 ms.
4. Play it on a syncopated 16th pattern in the 60–150 Hz zone (C1–G1, 65–98 Hz roots), with occasional notes a fifth or octave up. It should interlock with the kick, never double it.
5. Roar Hard shaper at 15% then a fast compressor to make every hit the same size.

Variations: Meld Drum engine for a more "tuned tom" character; Operator with a pitch envelope on a sine and 20% FM from a square for the classic grime-adjacent version.

Tuned metallic percussion (Collision + Corpus)

Bells, pipes, steel-drum-ish hits and pitched woodblocks fill the midrange instead of chords. Collision's physical model gives you tuned percussion that does not sound like a sample pack.

1. Collision: Mallet excitation with a hard stiffness, noise at 20% with a short envelope. Resonator 1 type Pipe, Resonator 2 type Marimba, mixed 60/40, decay 300–500 ms, Inharmonic amount around 15% for a bell-like detuning.
2. Play a 3-note pattern in fifths and fourths on the swung 16ths, rarely on beats 1 and 3. Velocity mapped to the mallet stiffness (via the Collision modulation) so accents are brighter.
3. Corpus with the Plate resonator and Tune enabled to the track key for a shared resonant ring across hits; 30% wet.
4. Auto Pan-Tremolo (12.3) in Auto Pan mode at 1/8 triplet for movement that crosses the swung grid; Echo on a triplet 8th for the dub-style spread.

Rave/grime-adjacent stab with dub throw (Analog + Echo)

Short, bright synth stabs (minor chords, often a single detuned note) mark the bar and get thrown into a long dub delay every 4 or 8 bars.

1. Analog: Osc 1 Saw, Osc 2 Square one octave down at −8 dB, both into Filter 1 (LP 12 dB) at 1.2 kHz with the filter envelope at 60%, decay 150 ms. Amp decay 180 ms, sustain 0.
2. Program a minor chord (root, b3, 5, with the root doubled) or a single note on the "&" of 2 and the "a" of 4, nothing else; silence is the arrangement.
3. Echo on a return: 3/8 left, 1/4 right, feedback 65–75%, Reverb 20%, Ducking on so the dry stab stays clear. Automate the send amount from 0 to 100% for one stab every 8 bars: the dub throw.
4. High-pass the return at 250 Hz and use Echo's own filter to roll off above 4 kHz so repeats get darker each cycle.

Variations: swap Analog for Wavetable with a Vintage table and Unison Phase Sync 2 voices for a harder, more "eski" stab; run the stab through Corpus with the String resonator for a plucked, kotoish version used in the sinogrime-influenced end of 140.

Chopped vocal fragment as rhythmic hook (Simpler + Beat Repeat)

Not a garage vocal, not a grime MC: a single word or syllable, pitched and placed as a percussive element, stuttered at the end of phrases.

1. Simpler, Classic mode, one word, Warp off, pitched down 2–4 st for weight. Amp decay 200 ms so it is a hit, not a phrase.
2. Band-pass filter around 1.2 kHz with some resonance: a "telephone" cut that keeps it out of the bass and the hats.
3. Beat Repeat with Chance 30% and Variation 4 so the stutter is unpredictable; raise Chance to 100% with a Gate of 1/4 for the last beat of every 8 bars (automate).
4. Erosion Wide Noise 20% for a slightly lo-fi grain; Echo ducked.

Dark reese for the post-dubstep end (Drift Unison + Roar Mid-Side)

The hollow, slowly beating reese of the darker UK bass records: two detuned saws, filtered dark, with the stereo width limited to the harmonics.

1. Drift, Unison voice mode with 2 voices and 10–15 cents detune. Both oscillators Saw, Osc 2 at −3 dB. MS4 filter at 400 Hz, resonance 15%, Drift amount 20%.
2. Amp: A 30 ms, D 1 s, S 0.8, R 200 ms. Long notes, one per bar, with occasional slides (Legato, Glide 120 ms).
3. Roar in Mid-Side routing: Soft Sine on the mid at 20% (fundamental stays clean), Hard clip on the side at 10% (the beating detune gets gritty), post filter LP 2 kHz. This is where the "dark" comes from.
4. Bass Mono at 150 Hz so the beating is only audible in the harmonics; the sub stays stable.
5. Sidechain from the kick, gentle (3 dB), because this reese is sustained and would otherwise bury the broken kick pattern.

Dub space: spring-ish reverb, noise beds and the pre-delay trick

The dry drums need a space around them that does not fill the bar. The trick is short, dark reverbs with long pre-delay, and one long delay used as an event.

1. Return A: Hybrid Reverb with a spring convolution IR (or Quartz with a short decay), pre-delay 30–50 ms, decay 1 s, low cut at 300 Hz. Send snare and percussion at −12 dB; the pre-delay separates the hit from the tail so the drums stay dry-sounding.
2. Return B: Echo with a long dotted-half delay, feedback 50%, the Noise and Wobble sections lightly on for tape character. Send only the stab and vocal cut, in bursts.
3. Return C: Spectral Time in Freeze mode, used as a pad generator: send one stab, freeze, and let it hang under the next 4 bars at 30%.
4. A noise bed (Wavetable Noise table through Auto Filter BP at 2 kHz, −30 dB) under the whole track gives the sense of a room without any reverb at all.
