How to Make Deathstep Bass in Serum: Extreme Sound Design Guide

What Is Deathstep?

Deathstep is the most extreme subgenre of dubstep. It takes the aggression of tearout and pushes it into territories inspired by death metal, horror soundtracks, and industrial music. The bass sounds are brutally distorted, the drops are relentless, and the atmosphere is pure darkness. Artists like Code: Pandorum, 1788-L, and Reaper define this sound.

If you think riddim or tearout is heavy, deathstep takes it several steps further. The bass sounds in deathstep are so heavily processed that they often sound more like distorted guitars or industrial machinery than traditional synth bass.

Sound Design in Serum

Oscillator Setup for Maximum Aggression

Start with Oscillator A loaded with a harsh wavetable. The Digital and Spectral categories in Serum contain wavetables with lots of dissonant harmonic content. Try Digital_Carbon, Spectral_Harsh, or import your own wavetable from a distorted recording.

Set unison to 4-7 voices with moderate detune and stack mode. Enable Oscillator B with a contrasting wavetable. The interaction between two aggressive wavetables creates the chaotic, unpredictable character that deathstep demands.

For extra brutality, enable FM modulation from Oscillator B to Oscillator A. This adds metallic, inharmonic frequencies that sound almost alien. Push the FM amount until the sound starts breaking apart, then pull it back slightly.

Extreme Distortion

Deathstep uses more distortion than any other genre. In Serum FX tab, stack three or more distortion modules. Start with Tube for base saturation, add Hard Clip for aggressive clipping, then Downsample for digital destruction. Each distortion type adds different harmonics.

After Serum, add external distortion. In Ableton, chain Saturator (Hard Curve) into Erosion for digital artifacts. In FL Studio, use Fruity Blood Overdrive into Fruity Waveshaper. The goal is total harmonic annihilation while keeping enough low-end weight to move a sound system.

The Scream Bass

Many deathstep tracks feature screaming, vocal-like bass sounds. Create these by using formant filters in Serum. The Vowel filter types (French LP, German LP) create vocal resonances. Assign an LFO to sweep through different vowel positions, creating a bass that sounds like it is screaming.

Add heavy distortion after the formant filtering to push the scream into extreme territory. Automate the filter envelope amount and LFO rate for dynamic, evolving screams.

Processing Chain

A typical deathstep processing chain: Serum (with internal distortion) > OTT (40-60% depth) > Multiband Distortion > Saturator > EQ (surgical cuts for problem frequencies) > Multiband Compression > Limiter

The key is maintaining low-end power through all this processing. Use a multiband approach where you process the mids and highs aggressively while keeping the sub relatively clean. Split your signal at around 150Hz and process each band independently.

Arrangement and Atmosphere

Building Dread

Deathstep intros and breakdowns should build a sense of dread and unease. Use dark ambient pads, reversed sounds, horror-style sound effects, and tension-building risers. Slow, low-frequency rumbles work well to create physical tension before the drop hits.

Cinematic percussion (taiko drums, industrial hits, anvil sounds) adds weight and drama to builds. Layer them with standard electronic drums for a hybrid acoustic-electronic feel.

The Drop

Deathstep drops are relentless. Use half-time drum patterns at 140-150 BPM with the heaviest possible kick and snare sounds. The bass should be constant and overwhelming, with brief moments of silence that make the return even more impactful.

Vary your bass sounds throughout the drop. Switch between different types of distorted bass, scream bass, and grinding textures every 4-8 bars. This keeps the listener engaged despite the relentless aggression.

Get Started

Our Dirty DnB and bass preset packs include aggressive bass patches that serve as excellent starting points for deathstep production. Layer them, process them heavily, and push them into extreme territory. Our bass one-shot samples also work great for layering with synth bass in deathstep drops.
