A supersaw lead in Serum is a stack of seven detuned sawtooth voices on Osc A, with detune around 0.25 and unison blend around 0.8, backed by a quieter lower oscillator for pitch, a 2-5 ms attack and a high-pass near 250-300 Hz. That is the recipe, and the rest of this guide is about getting it to survive a full drop.
The numbers are the easy part. What separates a supersaw that cuts through a mix from one that turns into mush is what happens after you build it: EQ, light saturation, returns on their own buses, and a very gentle duck to the kick. Skip those and the patch sounds enormous in solo, then disappears the moment a bassline comes in.
One habit worth adopting early, because it comes up constantly on r/edmproduction: detune less than feels right when you are playing it alone. Solo listening flatters wide unison stacks. Play the same patch over the actual kick and bass of your track and you will usually pull the detune back by a third before you even notice it going wrong.
Here is the whole patch on one screen. If you only have ten minutes, build it from this and stop.
| Control | Setting | Why |
|---|---|---|
| Osc A wave | Saw, octave 0 | The harmonic body of the lead |
| Osc A unison voices | 7 | Standard supersaw thickness |
| Osc A detune | 0.25 | Wide enough to shimmer, tight enough to hum |
| Unison blend | 0.8 | Keeps the detune audible instead of washed out |
| Stereo width | 60 | Wide image without an unstable listen |
| Osc B wave | Saw, octave -1, level -8 dB | Pitch anchor underneath the width |
| Amp envelope | Attack 3 ms, release 200 ms | Fast enough to cut, long enough to avoid clicks |
| Low-pass filter | 8 kHz, 24 dB/oct | Removes sizzle before it becomes fizz |
| Bus high-pass | 280 Hz | Clears space for the bass |
| Saturation | Light soft clip | Perceived loudness without extra level |
| Kick sidechain | 2-3 dB depth | Lets the kick transient read |

What You Need
To build this you need Xfer Serum, either version. Everything described here works in Serum 1 and carries over to Serum 2, including the granular and spectral oscillator types in the newer build, although for a lead this big a plain saw is still the right starting wave.
You also need a DAW and a MIDI clip to play. Write the melody as a single held chord or a two-note riff before you touch the synth. A supersaw with nothing to say is much harder to judge than one playing four bars you already like.
The part people skip is the reference material. Drop your actual kick and bass on the session, at the level they will sit at in the master, and build the lead against them. Every number in this guide assumes you are auditioning over a real drop rather than in an empty project.
For monitoring, plain headphones are fine for building and near-impossible for judging width. A supersaw with too much stereo spread sounds huge on cans and hollow on a system, so check the finished patch on speakers at least once before you commit to it.
Plugin-wise you need very little. Any EQ, any saturator or soft clipper, and any reverb and delay will do. Pro-Q 3, TDR Nova, Valhalla VintageVerb, Saturn 2 and KClip are all common choices, but the chain below is written as functions, not brands, so any equivalents work.
How to Make a Supersaw Lead in Serum Step by Step
There are four stages: oscillators, unison width, filter and modulation, then bus processing. Build them in that order and you can hear what each stage contributed, which is the only reliable way to fix something later.
How to Make a Supersaw Lead in Serum: Start With the Oscillators
Load Serum, click Init Sound in the bottom left, and leave everything else alone for a minute. Osc A with a saw wave at octave 0 is your whole harmonic foundation, and it is the only oscillator doing real work at this stage.
Turn on Osc B, set it to a saw at octave -1, and pull its level down to about -8 dB relative to Osc A. This lower voice is what gives the lead a defined pitch when the detuned stack gets wide. If you can no longer hum the melody back, that lower octave is the first thing to restore.
Two small details matter here. Enable Rand, the phase randomisation option next to the oscillator, so each retrigger starts the voices at slightly different phases and stops the patch from clicking or zapping on repeat notes. And keep Osc B un-modulated and un-panned until the lead is sitting right in the mix.
Open the amp envelope and set attack to around 3 ms. Serum’s default attack is long enough to soften the transient of a single oscillator, but a supersaw needs to read as an instant so it competes with a kick drum. Release around 200 ms stops notes from stacking into mush when your melody holds long chords.
Shape the Supersaw Width With Unison and Voices
Seven unison voices on Osc A, detune at 0.25 and blend at 0.8 is the starting point that most producers land on, and it is where this guide started too. Set the stereo width control to around 60 and leave drift low.
Blend and detune do different jobs, and confusing them is why many patches sound wrong. Detune spreads the voices apart in pitch, which creates the shimmer and the slow beating. Blend decides how much of that detuned signal survives, and dropping it too low flattens the whole stack back toward a single saw.
Drift is the slow random wander in voice placement. A little makes the patch feel alive and less static. A lot makes it wobble in a way that draws attention to itself, which is usually wrong for a lead that has to carry a melody.
Now do the detune test, which is the part most guides skip. Hum the melody to yourself, then mute the patch. If you cannot hum it back accurately, you are too wide. Pull detune down in steps of 0.05 until you can, then check it over the kick and bass before you accept it.
The classic Reddit approach goes further with the harmonic conflict. When two notes in a chord have different fundamentals, they beat against each other, so builders notch the shared tones roughly 3 dB at the fundamental, 6 dB at the second harmonic and 9 dB at the third. That keeps a big chord from turning into a flam.
Rather than duplicating your MIDI across six instances, you can get most of this inside one patch with two layers:
| Parameter | Wide layer | Core layer |
|---|---|---|
| Wave | Saw | Saw |
| Octave | 0 | -1 |
| Unison voices | 7 | 3 |
| Detune | 0.25 | 0.08 |
| Blend | 0.8 | 0.5 |
| Stereo width | 80 | 0 |
| Relative level | -4 dB | 0 dB |
| Bus high-pass | 280 Hz | 200 Hz |
| Attack | 3 ms | 3 ms |
The core layer is nearly mono and nearly undetuned, so it holds the pitch centre through headphones and on a phone speaker. The wide layer does the emotional work on top of it.
Add Movement With Filters, Envelopes, and LFOs
Set the low-pass filter to around 8 kHz with a steep slope. This is the single most effective step for keeping a supersaw from sounding fizzy, because it removes the top octave of sizzle before it builds up.
Once that sits right, add a filter envelope on a slow attack, roughly 2-4 seconds, routed to cutoff with a modest amount. A little movement keeps a long pad-like lead from sitting still, and a slow attack means the filter never closes completely, so the lead stays present throughout the note.
For extra motion, put an LFO on wavetable position with a slow rate and a small depth. Even with a plain saw selected, small position changes add subtle timbral drift. Another LFO on filter frequency at a slow rate adds a breathing quality that reads as movement on a big system and mostly disappears on laptops, which is exactly what you want.
Resonance deserves a note. A touch of it adds bite around the cutoff, and this is exactly where leads become tiring at drop volume, so add it last and keep it subtle. If your ears start to ache during the loudest section, resonance is one of the first things to pull back.
Finish the Lead With Effects and Level Control
Serum’s own distortion sits after the filter, so engage it once the filter is where you want it and set the drive low, around 10-20 percent. More than that and it turns into a different instrument rather than a lead with more weight.
On the bus, follow this order and stop at each stage to listen:
1. High-pass. 24 dB/octave at 250-300 Hz. Below that the lead and bass are fighting in the same register, and no amount of volume fixes it. Producers on r/edmproduction treat this as non-negotiable, and so should you.
2. Notching. A narrow bell cut around 300-500 Hz where the honk sits, and a gentle dip of a couple of dB near 3 kHz. Make these cuts before any boost. Boosting 5-8 kHz to make a lead cut through is the most common reason leads sound harsh and tiring.
3. Saturation. A tape saturator or soft clipper adds upper harmonics and makes the patch sound louder without raising the fader. Go easy, and re-check the 3 kHz region afterwards because saturation creates its own brightness there.
4. Compression. Roughly 4:1 with a slowish attack, just enough to glue the movement together. Compressing the lead hard removes the dynamics that make it feel alive.
5. Returns. Send to a reverb and a tempo-synced delay, each on its own bus with its own EQ. A dotted eighth ping-pong delay, low-passed around 4-5 kHz on the return, sits well behind the lead without smearing across downbeats. Automate the send level rather than the return volume so the tail follows the arrangement.
6. Sidechain. Duck the lead to the kick by 2-3 dB with a reasonably fast attack and a slower release. Any deeper and the lead sounds visibly pumped. Sidechain the return as well, not just the dry signal, or the reverb tail will fill the gaps and undo the effect.
Save the finished patch and, if your DAW supports it, the whole chain as a rack or template. Next time you want a second lead for a breakdown, you duplicate the chain rather than rebuilding it from memory.
Genre Variants: Trance, Future Bass, Hardstyle and Dark
The same architecture covers most EDM styles. What changes is brightness, note length and how much detune the arrangement can carry.
| Style | Detune | Low-pass | Attack | Drive and notes |
|---|---|---|---|---|
| Uplifting trance | 0.25-0.30 | 8-10 kHz | 3 ms | Low drive, long reverb send, wide |
| Future bass / future house | 0.20-0.25 | 6-8 kHz | 5 ms | Medium drive, sidechain deeper, gated notes |
| Hardstyle / rave | 0.15-0.20 | 4-6 kHz | 1-2 ms | Heavy drive, short delay, distorted midrange |
| Dark / aggressive | 0.10-0.15 | 800 Hz-1.5 kHz | 3 ms | Fast filter envelope, little reverb |
The pattern is clear: brighter genres want more detune and a higher cutoff, darker ones want the opposite and a filter that snaps shut quickly.
Common Mistakes
Too much detune. The most common error, and the fix is a test rather than a number. Hum the melody back, mute the patch, repeat. If you cannot sing it accurately, pull detune down by 0.05 and check again over the drop.
The lead vanishes under the bass. This is a low-mid problem, not a volume problem. High-pass at 250-300 Hz, notch the 300-500 Hz region, and pull 2-3 dB out of the bass rather than pushing the lead up. Then add the 2-3 dB kick sidechain and listen to the transient.
Harshness around 3 kHz. Saturation and resonance both add energy there. Cut before you boost, low-pass around 8-12 kHz, ease the saturation back if the level rises as you add it, and resist any boost in the 5-8 kHz range to make the lead cut.
Muddy low frequencies. Seven voices each contributing low-mids will double up with the bass and with themselves. High-pass the wide layer harder than the core layer, and keep anything below 150 Hz summed to mono.
Unstable stereo width. Extreme width sounds enormous in headphones and collapses on a system. Bring the width control down toward 60, reduce drift, and check the patch on speakers.
Overmodulation. LFO on wavetable position, filter LFO, a vibrato LFO and an aftertouch route all at once will make the lead drift aimlessly. Pick one motion source, keep the depth small, and let the arrangement provide the movement instead.
Effects on inserts instead of returns. Reverb and delay applied directly make the lead sound washed out and smear across the transients. Put them on sends with their own EQ.
Static MIDI. This one is not a setting, and it is the difference between a patch that sounds programmed and one that sounds played.
Keep gate length between roughly 30 and 50 percent of the note length, and vary it. A chord that holds for two bars and the same chord held for a bar and a half sound completely different. Push most notes to a velocity of 90 to 127 with a few quieter ones for ghosting, add small pitch scoops into the first downbeat of a phrase, and humanise timing by a few milliseconds so the line breathes. In Serum, mapping velocity to filter cutoff gives the quieter notes a darker edge without you touching them by hand.
Frequently Asked Questions
How many unison voices and how much detune should a supersaw lead use in Serum?
Seven unison voices on Osc A with detune near 0.25 and blend around 0.8 is the standard starting point, and it is the number most producers settle on. Push detune past 0.4 and the fundamental blurs until you cannot hum the melody back. Test it over the drop’s kick and bass rather than in solo.
Why does my supersaw disappear under the bass in the drop?
It is almost always low-mid conflict rather than level. High-pass the lead bus around 250-300 Hz on a steep slope, notch the 300-500 Hz region where the bass body sits, and cut the bass instead of pushing the lead up. A gentle kick sidechain at 2-3 dB depth then lets the transient read without the lead sounding pumped.
Should I layer several supersaw instances or build it inside one patch?
Start inside one patch. Two oscillators plus Serum’s unison give you a wide layer and a core layer without duplicated MIDI fighting itself. Once that sits properly in the mix, add a second instance panned wide and high-passed harder if you need more air. Six-instance stacks are an arrangement decision, not a starting point.
How do I make a dark, aggressive supersaw instead of a bright trance lead?
Drop the low-pass to roughly 800 Hz to 1.5 kHz with a fast filter envelope so it snaps shut, add more drive after the filter, and pull unison detune back to 0.10-0.15 so the pitch stays solid. Pull the reverb and delay sends down. Dark leads get their weight from density and note length, not brightness.
Can I make the same supersaw sound in other synths like Sylenth1 or Diva?
Yes, because the recipe is about osc layering, unison width and envelope shape rather than any one synth. In Sylenth1 you build it from two detuned saws with a unison control per oscillator. In Diva you stack two oscillators and pan them yourself. Keep the numbers identical: 7 voices, detune 0.25, blend 0.8, 3 ms attack.
How do I stop a supersaw sounding harsh and fizzy?
Cut before you boost. Low-pass around 8-12 kHz to remove the sizzle, take a narrow bell out near 3 kHz, and add light saturation to restore perceived loudness instead of reaching for an EQ boost at 5-8 kHz. If it still tires your ears after ten minutes of the drop, your detune is probably wider than it needs to be.
Conclusion: Start With a Clean, Controlled Supersaw
Start with seven unison voices on a saw, detune at 0.25, blend at 0.8, and a saw an octave down at -8 dB underneath it. Give it a 3 ms attack, low-pass at 8 kHz, and leave the bus clean for now.
Then play it over your drop. High-pass at 280 Hz, notch the 300-500 Hz region, add light saturation, put reverb and delay on returns, and sidechain by 2-3 dB. Save the chain as a template and duplicate it for every lead that follows.
