Every few weeks someone emails me asking how to get that lush, expensive RnB sound — the warm electric pianos, the soft pads, the round sub bass you hear on records by SZA, Brent Faiyaz or Summer Walker. The honest answer: it’s mostly sound choice. Get the right patches and the rest is chords and restraint.
I make preset packs for a living, so I spend a stupid amount of time inside Serum. In this post I’ll show you which RnB Serum presets are worth your time in 2026, what actually makes a patch sound “RnB”, and the concrete settings I use when I build these sounds myself.
First, a quick update: Serum is now Serum 2
This post originally went up when Serum 1 was the standard. In March 2025 Xfer released Serum 2 as a free upgrade for every Serum 1 owner. If you haven’t updated yet, do it — it’s the same license, no extra cost.
For RnB specifically, Serum 2 matters more than for most genres. You now get 3 oscillators instead of 2, plus 5 synthesis engines including granular and spectral. That means real sampled electric pianos and vocal textures can live inside the synth, not just wavetables. The new FX buses also let you send your keys to one reverb and your bass to a separate chain — huge for keeping the low end clean.
All Serum 1 presets load fine in Serum 2, so nothing below is wasted no matter which version a pack was originally built in. If you’re new to the synth, my Serum 2 beginner guide covers the layout in plain language.
What makes a preset actually sound like RnB
Before you buy anything, it helps to know what you’re listening for. When I design RnB patches, these are the ingredients that matter:
- Soft attack, long release. RnB keys almost never snap. I set amp attack around 5–15 ms and release at 400–800 ms so chords bleed into each other.
- A closed low-pass filter. Most of the warmth comes from rolling the filter down to 1–2 kHz with a gentle 12 dB/oct slope. Bright presets read as EDM, dark ones read as RnB.
- Slow chorus or ensemble. A chorus at around 0.3 Hz rate and 25–35% mix gives you that classic swirling EP movement without sounding seasick.
- Subtle detune. 2–4 unison voices with detune around 0.05–0.10, not the supersaw settings you’d use for a festival lead.
- Clean sine sub. The bass is usually a sine or triangle with a touch of saturation for small speakers. Nothing clever — the character lives in the keys and vocals.
A good commercial pack bakes all of this in, which is exactly why presets save so much time in this genre.
The RnB packs I’d actually start with
These are from my own catalog, so obvious bias — but they’re also the packs this post has always been about, kept up to date for Serum 2.
RnB Serum 2 Presets Vol.1 is the core pack: pads, keys, plucks, strings and sub basses voiced for modern RnB. Every patch has the macros mapped, so mod wheel and macro 1 do something musical out of the box. Here’s a raw preset demo, no external processing:
If you want finished musical material to write over, RNB Vol.1 is a sample pack that covers both the modern and the 90s side of the genre:
A few more, depending on what you’re missing:
- KRADE Premium R&B/Hip-Hop Sample Pack — melody loops and one-shots that sit between RnB and hip-hop, good for trap-soul type beats.
- Organica — organic textures and Serum-made melodic loops for a warmer, less digital feel.
- On Vital instead of Serum? The RnB Sound Collection for Vital covers the same territory for the free synth.
And if you want to test my sound design before spending anything, grab the free Serum 2 presets pack — 250+ patches, several of them straight-up RnB keys and pads.
Whichever pack you pick, install it properly the first time. Here’s how to install Serum 2 presets so they show up in the browser instead of a random folder.
Production techniques that do the heavy lifting
Presets get you the raw tone. These habits get you the record-ready sound.
Chords before sound design
RnB is a harmony genre. Minor 7ths, 9ths and sus2 voicings will make even a plain preset sound expensive. If you play a bare minor triad through the best patch in the world, it’ll still sound like a demo. Steal voicings from records you love — that’s what everyone does.
EQ and compression, with numbers
On keys and pads I usually high-pass at 100–150 Hz so they stay out of the bass’s way, cut 2–3 dB around 300–500 Hz if things get muddy, and add a small high shelf (+1–2 dB at 10 kHz) for air. Compression is gentle: 2:1 or 3:1 ratio, slow attack (20–30 ms), 2–4 dB of gain reduction. You’re gluing, not pumping.
Space
Reverb with 20–40 ms of pre-delay keeps chords lush without washing out the transient. A dotted-eighth delay at 15–20% mix on lead lines fills gaps between vocal phrases. In Serum 2 I often build this into the preset itself using the FX buses — my Serum 2 effects guide walks through that routing.
Vocal textures
Modern RnB leans hard on pitched vocal chops and breathy textures behind the hook. Serum 2’s granular engine makes this easy — drop a vocal phrase in, slow the grain position, and you have an instant atmosphere. I wrote a separate vocal chops tutorial if you want the step-by-step.
Should you use presets if you’re not a sound designer?
Yes, and I’d argue especially then. Nobody asks a guitarist to wind their own strings. Presets are instruments: you’re paying for someone’s hours of filter tweaking so you can spend yours writing songs.
The underrated part is that presets teach. Open a patch you like, click through the oscillators, look at what the LFOs are mapped to. That’s how most working producers actually learned synthesis — reverse-engineering sounds they liked, not reading manuals.
The one habit I’d push: never use a preset completely stock on a serious record. Change the filter cutoff, swap a wavetable, re-time the LFO. Five minutes of tweaking makes the sound yours and keeps two producers from releasing the same patch on the same week.
FAQ: RnB Serum presets
Do Serum 1 RnB presets work in Serum 2?
Yes. Serum 2 opens every Serum 1 patch and keeps it sounding identical, and the upgrade is free for Serum 1 owners. All the packs mentioned here work in both, though the newer ones take advantage of Serum 2’s extra oscillator and FX buses.
What sounds do I need for a modern RnB beat?
A minimum kit: one electric-piano or keys patch, one dark pad, a clean sine sub, one pluck or bell for melodies, and some vocal texture. That’s five sounds. Most classic RnB productions use fewer elements than beginners expect — space is part of the style.
Are free RnB presets good enough to release music with?
Some are. The quality gap between free and paid is smaller than it used to be — the paid packs mostly buy you consistency and coverage. Start with a free pack, and upgrade when you keep reaching for sounds it doesn’t have.
Why do my chords sound thinner than on real records?
Usually it’s voicing and layering, not the preset. Spread your chord across two octaves, add a 9th, and layer a quiet pad an octave above the keys. Then check you’re not high-passing the keys too aggressively — 100 Hz is plenty.
That’s the whole playbook: warm presets, rich chords, gentle processing, lots of space. If you want to try my take on the sound first, the 250+ free Serum 2 presets are yours — no catch, just load them up and play some 9th chords.
I run Monosounds.studio and make the packs myself. Ten-plus years of producing, 97+ releases, 16,000+ downloads. Every Serum 2 preset we ship passes a CPU check on a mid-range laptop and gets used in a real track before release. If it does not survive a mix, it does not go in the pack.
