Drum & Bass Sequencing Guide
How to build drum & bass patterns on the sequencer's 4×16-step sound cards. All patterns assume ~174 BPM.
Grid & Timing Reference
1 bar (16 sixteenth-notes)
Beat 1 Beat 2 Beat 3 Beat 4

D&B uses a half-time feel: the snare lands on beats 2 and 4 (steps 5 & 13) while the kick anchors beat 1 (step 1).
Each sound card uses one 4×4 grid per page. In the diagrams below:
- ▓ = active step
- ░ = inactive step
- Active step numbers listed below each grid
Drum Patterns
1. Standard 2-Step
The foundation pattern. Kick on 1 and the "two-step" ghost kick on 11. Snare on 2 and 4 (half-time). Hi-hats lock down the groove.

Variations: - Step 9 kick (beats 1 & 3): add step 9 for a heavier drop feel - Swung hats: shift 8th-note hats slightly — use the Chance tab at ~85% on steps 3, 7, 11, 15 for a looser swing - Velocities: snare on step 5 at 0.85, snare on step 13 at 0.75 (slight backbeat emphasis)
2. Amen Style
Inspired by the Amen break. Syncopated kicks with ghost snares create the rolling breakbeat feel.

Steps: 4, 6, 12
Tips: - Ghost snares (steps 3, 6, 12) should be low velocity (~0.3–0.4) — use the Vel tab - The ride hit on step 4 keeps the break rolling - Set snare velocity on step 5 to 0.9 and step 13 to 0.7 for dynamic feel
3. Jump-Up
Heavier, more aggressive. Double kick on beats 1 & 3 with swung, rolling hi-hats.

(· = step off; ▓ = full velocity; ░ = lower velocity)
Tips: - The kick on step 9 (beat 3) gives it the heavy "two-step" bounce - Swung hats avoid step 2 and 10, creating a lopsided roll - Use the Chance tab at ~70% on steps 4 and 12 for variation
4. Liquid
Lighter, more spacious. Minimal kick, open hats on off-beats, room for the bass to breathe.

Tips: - Minimal kick leaves space for a sub bass that plays on 1 and 5-9 - Open hats on steps 7 and 15 give the "splash" on the & of 2 and 4 - Set the open hat Decay (Hi-Hat engine) longer (~0.15s) for a washy feel
5. Neurofunk
Tight, precise, mechanical. Kick on 1 and the "& of 3" for a syncopated punch. Rolling hats with a crisp, programmed feel.

Steps: 2, 4, 6, 8, 10, 12, 14, 16 (higher velocity than main hats)
Tips: - Kick on 11 (not 9) gives the distinctive neuro "syncopated punch" - Use the Vel tab: main hats at 0.5, ghost hats at 0.8 for an accented roll - Try the Chance tab at ~90% on random steps for subtle micro-variation - The snare should be punchy and dry — use the Snare engine with a short decay (~0.1s)
6. Fills & Variations
One-bar fills to transition between sections. Width is the step range covered (e.g. steps 9–16 = second half of the bar).

- Set velocities ramping: 0.4 → 0.5 → 0.6 → 0.7 → 0.8 → 0.9 → 1.0 → 1.0
- Use the same snare sound or a different snare on a separate sound card

Bass Patterns
These use the Note tab on a Neuro or Juno sound card. The grid shows note names relative to the transport's Key and Scale settings. All examples use C major scale with Oct 3.
1. Sub Foundation
Root note on 1, octave on 9. Simple, deep, effective.

Quick Tips
Velocity (Vel Tab)
| Pattern | Snare | Kick | Hats |
|---|---|---|---|
| 2-Step | 0.85 / 0.75 | 0.9 / 0.7 | 0.5 |
| Amen | 0.9 / 0.7 / 0.3 | 0.9 / 0.6 / 0.4 | 0.4 |
| Jump-Up | 0.9 / 0.85 | 1.0 / 0.9 | 0.5–0.7 |
| Liquid | 0.7 / 0.6 | 0.8 | 0.4 / 0.6 (open) |
| Neuro | 0.9 / 0.85 | 1.0 / 0.85 | 0.5 / 0.8 (accents) |
Chance (Chance Tab)
- Set stepped hi-hats to 85–90% for a "humanised" roll
- Ghost snares at 50–70% for random variation
- Neuro accents at 80% for occasional punch
Modulation (Mod Tab)
Route the per-step mod value to the Neuro engine's filterCut or the Kick's
pitchStart for timbral movement across the pattern. Set mod values on active
steps in the Mod tab (grid of per-step values 0–1).
Pattern Length
Start with 16 steps (1 page) while building. Extend to 32 (2 pages) for call-and-response phrasing. The Kick and Snare patterns stay at 16; variations on pages 2+ keep the loop from getting stale.

Key & Scale Reference
The Note tab uses the transport's Key and Scale settings to determine which notes appear when you click a pad. Below are common D&B keys with their scale note names across 3 octaves (as they'd appear in the Note tab cycling).
Scales
| Scale | Intervals | Sound |
|---|---|---|
| Chromatic | All 12 semitones | Any key, all notes available |
| Major | W–W–H–W–W–W–H | Bright, uplifting |
| Minor | W–H–W–W–H–W–W | Dark, emotive |
| Pentatonic Minor | W–WH–W–WH | Safe, always in key |
| Blues | Minor pentatonic + ♭5 | Gritty, expressive |
| Dorian | W–H–W–W–W–H–W | Moody, used in neuro |
| Phrygian | H–W–W–W–H–W–W | Dark, spanish flavour |
(W = whole tone, H = semitone, WH = 3 semitones)
Common D&B Keys
D&B favours darker, sub-heavy keys. These are the most common:
| Key | Root Freq | Notes in Scale (Natural Minor) | Feel |
|---|---|---|---|
| D minor | 73.4 Hz | D, E, F, G, A, Bb, C | Classic D&B, deep sub |
| E♭ minor | 77.8 Hz | Eb, F, Gb, Ab, Bb, Cb, Db | Dark, heavy |
| E minor | 82.4 Hz | E, F#, G, A, B, C, D | Most common — rich sub |
| F minor | 87.3 Hz | F, G, Ab, Bb, C, Db, Eb | Aggressive, used in jump-up |
| F# minor | 92.5 Hz | F#, G#, A, B, C#, D, E | Neurofunk favourite |
| G minor | 98.0 Hz | G, A, Bb, C, D, Eb, F | Dark, rolling |
| A minor | 110.0 Hz | A, B, C, D, E, F, G | Lighter, liquid-friendly |

Clicking a pad cycles through: E2 → E3 → E4 → E5 → E6 → OFF.
Right-click clears the note immediately.
Bass Note Selection by Key
Use these root-fifth-root-octave patterns as your sub foundation:
| Key | Sub Root (1) | Fifth (5) | Octave (9) | Octave Fifth (13) |
|---|---|---|---|---|
| D | D2 | A2 | D3 | A3 |
| E♭ | Eb2 | Bb2 | Eb3 | Bb3 |
| E | E2 | B2 | E3 | B3 |
| F | F2 | C3 | F3 | C4 |
| F# | F#2 | C#3 | F#3 | C#4 |
| G | G2 | D3 | G3 | D4 |
| A | A2 | E3 | A3 | E4 |
Typical Bass Movement by Sub-genre
| Sub-genre | Movement | Example Pattern |
|---|---|---|
| Liquid | Root → 5th → Root → 5th (1-bar) | E2(1), B2(5), E2(9), B2(13) |
| Neuro | Root → off → 3rd → 5th (syncopated) | E2(1), G3(4), B3(6), D4(10) |
| Jump-Up | Root → octave → root → off | E2(1), E3(5), E2(9) |
| Rolling | Root → octave → 5th → octave 5th | E2(1), E3(5), B2(9), B3(13) |
| Techstep | Root → off → off → 5th (minimal) | E2(1), B3(11) |
Using the Mod Tab for Bass Movement
Route per-step mod to the Neuro engine's filterCut or fmAmount:
| Step | Note | Mod | Effect |
|---|---|---|---|
| 1 | E2 | 0 | Closed filter, deep sub |
| 6 | G3 | 0.5 | Filter opens, growl |
| 10 | B3 | 0.8 | Full open, aggressive |
| 14 | D4 | 0.4 | Filter closes back |
This creates the classic neuro "wobble" where the filter track-follows the note pitch with a dynamic envelope.
