How to Program Drum and Bass Drums at 174 BPM

Learn › Drum Programming & Arrangement › Programming DnB Drums

Drum and bass is a drum-led genre. Knowing how to program drum and bass drums properly is the single biggest difference between a DnB track that works and one that does not - the relentless 174 BPM pulse, the busy hi-hat patterns, the rolling snare placement that makes drum and bass feel like it is constantly moving forward. The bass might be what people remember, but the drums are what makes the energy work.

This guide goes deep on the DnB drum pattern. The conventions, the variations, the signature techniques that working DnB producers use, and how to apply them in the three major DAWs.

How to Program Drum and Bass Drums - The Anatomy

The classic DnB drum pattern is built around a 2-bar phrase. Inside that phrase, the kick and snare placement creates the genre's rhythmic identity.

Halftime vs Full-Time Feel

One of the most important choices in DnB drum programming is whether to play at full speed or halftime. The tempo stays at 174 BPM either way, but the snare placement transforms the feel completely.

Full-time DnB places the snare on beats 2 and 4 of every bar. This is the genre default - what most people picture when they think of DnB drums. The pulse feels fast and constant, perfect for energetic dancefloor moments.

Halftime DnB places the snare on beat 3 only of each bar (so beat 3 of bar 1 and beat 3 of bar 2). The tempo is still 174 BPM but the perceived feel is closer to 87 BPM. This gives DnB a dubstep-like weight and is the foundation of halftime DnB, a sub-genre that has grown massively since the mid-2010s. Producers like Mefjus and Ivy Lab have built careers in this territory.

Many modern DnB tracks switch between halftime and full-time across the arrangement - halftime in intros and breakdowns for weight, full-time in the drops for energy.

Hi-Hat Patterns - Where DnB Lives

Hi-hats are where DnB drum programming gets distinctive. A basic 8th-note hat pattern is fine but generic. The genre's character comes from busier, more varied hi-hat work.

Straight 16ths. Hi-hat on every 16th note - 16 hits per bar. The default for high-energy DnB. Combined with velocity variation, this is the foundation pattern that 80% of dancefloor DnB tracks use.

Triplet patterns. Hi-hats in triplet groupings (3 hits per beat instead of 2 or 4) create a rolling, syncopated feel against the 4/4 kick and snare. Often used as a fill or to differentiate a section. Listen to Calibre tracks for masterful triplet hat work.

16ths + triplet layering. Two separate hi-hat sounds - one playing straight 16ths, another playing triplets - layered on top of each other. The clashing rhythms create a complex, busy feel that defines technical DnB. Used heavily by producers like Noisia and Calyx & TeeBee.

Open hat accents. A single open hat hit on the offbeat (the "and" of beat 4, for example) creates a hook that ear locks onto. Sparingly used but instantly recognisable when present.

The Skip Snare and the Ghost Kick

Two techniques separate professional DnB drum programming from amateur work. Both are subtle, both are essential.

The Skip Snare

An additional snare hit on the 16th note immediately before the main snare on beat 4. The pattern becomes: snare on beat 4, plus a quieter snare on the 4th 16th of beat 3 (which is the 16th immediately before beat 4). The result is a syncopated "tah-DAH" feel where the small snare hit punches into the big snare hit.

Velocity matters. The skip snare should be at velocity 50-70 - audible but not competing with the main snare. Use it on every other bar, not every bar, to keep it from feeling mechanical.

The Ghost Kick

A very quiet kick hit (velocity 30-50) placed on a 16th note where no kick would normally sit - typically the 16th immediately before or after a main kick hit. The ghost kick is felt rather than heard, adding rolling motion to the pattern and giving the kick a "ramp into" feel.

Use ghost kicks sparingly - one or two per 2-bar pattern is plenty. Too many and you lose the impact of the main kicks.

Syncopation Techniques

Syncopation means placing accents on weak beats (off-beats and 16th notes that fall between the main beats). DnB drum programming relies heavily on syncopation to create the genre's busy, forward-driving energy.

Adding Ghost Notes for Texture

Ghost notes are the texture layer underneath the main rhythm - very quiet hits that fill the spaces between main beats. Already covered in the drum programming fundamentals guide, but for DnB specifically:

Ghost snare placement in DnB typically sits at the 4th 16th of beat 1 (just before the snare on beat 2) and the 2nd 16th of beat 2 (just after the snare). Velocity 30-50. These notes give the snare a fluttering, rolling quality essential to the DnB sound.

Ghost kicks as already discussed - 1-2 per 2-bar pattern, placed on 16ths around the main kicks. Very low velocity (30-50). Used to add forward motion and rolling feel.

Ghost percussion - shakers and tambourines at extremely low velocity (20-40) filling the 16th notes between hi-hats. Almost inaudible individually but creating a busy, played feel when stacked.

Reference Patterns from Classic DnB

Studying reference tracks systematically is the fastest way to internalise DnB drum programming. Here are the producers whose drum work defines the genre and is worth studying carefully.

DAW-Specific Tips

Ableton Live

Use a Drum Rack with each kit piece on its own pad. The Drum Rack's chain list lets you set up round-robin sample selection - alternating between two or three snare samples each time a snare note plays - which is essential for natural-sounding repeated hits.

Use the Piano Roll's velocity lane to draw natural-looking velocity curves rather than setting velocity note-by-note. Ableton's grid is in 16ths by default; switch to 32nds (Right-click in clip view) for triplet patterns.

FL Studio

The Step Sequencer in the Channel Rack is fast for sketching DnB patterns. Each drum gets its own channel with steps for the bar. Right-click steps for velocity, ghost notes (lower-volume steps), and shifted timing.

Switch to the Piano Roll for finer editing - micro-timing, ghost note placement, and velocity curves. FL's Piano Roll is widely regarded as the best of the three DAWs for detailed work.

Logic Pro

The Drum Machine Designer is Logic's equivalent to Ableton's Drum Rack. Each pad triggers a sample with built-in pitch, filter and amp envelope controls. The Step Sequencer added in Logic 10.5 is excellent for DnB pattern construction.

Logic's MIDI editor has the deepest velocity editing tools - per-note velocity scaling, randomisation, and graphic curve drawing all built in. Use these for natural-feeling velocity variation across your DnB pattern.

Polyrhythmic Variations

Beyond the standard DnB pattern, polyrhythmic drum programming creates the technical, advanced feel of producers like Current Value and Phace. The concept: placing rhythmic patterns in different time signatures on top of the 4/4 base.

Practical example: keep the kick and snare on a standard 4/4 pattern but program the hi-hats in groups of 3 (a 3-against-4 polyrhythm). The hat pattern repeats every 3 16th-notes while the kick and snare repeat every 4 16th-notes. The two patterns realign every 12 16th-notes (every 3 beats) creating a complex, cyclical feel.

Used sparingly, polyrhythms add technical complexity. Used everywhere, they confuse the listener. Reserve polyrhythmic moves for fills, transitions, or specific sections rather than running them throughout a track.

Key Takeaways

▸ What to remember from this guide

1. The DnB drum skeleton: kick on beat 1 and 3, snare on 2 and 4, hi-hats on 8ths or 16ths. Everything else is variation.
2. Halftime feel places the snare on beat 3 only - DnB at the same tempo but with dubstep-like weight.
3. Hi-hat patterns define DnB drum character. Straight 16ths, triplets, or both layered on top of each other.
4. The skip snare (extra quiet snare just before beat 4) and ghost kick (very quiet kick between main hits) are the two techniques that separate amateur from professional DnB drums.
5. Syncopation and ghost notes are not optional. They are what makes DnB feel like DnB.
6. Vary bar 2 from bar 1. The 2-bar pattern with asymmetric internal variation is the standard DnB rhythmic unit.
7. Study reference tracks systematically. Photek, Goldie, Noisia, Calibre - listen with intention, not just for enjoyment.
8. Tempo matters. 174 BPM is the default. Faster or slower changes the genre's feel substantially.

DnB Drum One-Shots and Loops

Programming DnB drums from scratch teaches you the underlying patterns. But every working DnB producer also has a deep library of drum one-shots and loops to draw from - building blocks that speed up the process and add character that pure synthesis cannot match.
