Remaking the bass synth from the 2018 song "Sunflower (Spider-Man Into the Spider-Verse)" by Post Malone and Swae Lee can be an exciting challenge for any synthesizer enthusiast. Here’s how you can create the "Sunflower (Spider-Man Into the Spider-Verse)" bass patch and play this iconic sound on most hardware or software subtractive synthesizers (Serum, Vital, Pigments, Prophet, Korg, Moog, etc). We've included the preset download directly for your convenience, but we strongly recommend you use our programming tutorial to recreate it yourself.
Original Audio
The synth bass in Post Malone and Swae Lee’s *Sunflower* (featured in *Spider-Man: Into the Spider-Verse*) emerges at 0:06 with a gritty, warm, smeared texture made with layers of pulse-width modulation (PWM) and wide unison detuning. This smeared, analog-inspired tone is shaped by a slow filter decay that creates the distinctive “eeow” shape, blending aggression with a rounded low-end.

Our Remake of The Bass Synth
This audio clip is how close we've matched the original tone of the bass synth from the song "Sunflower (Spider-Man Into the Spider-Verse)" by Post Malone and Swae Lee, giving you a reference point as you design your own synthesizer preset. Play it as often as you need to familiarize yourself with the nuances of the sound.
Synth Patch Programming Recipe
Getting Started
- Start by initializing your synthesizer to a plain saw with no filter, modulation or effects. For soft synths use the "init"/"default" preset or the the button to reset all parameters to their default factory values.
- No two synths are exactly alike, so treat the values below as approximate, and use your ear.
- Percentage values (e.g. 50%) represent the relative position of a knob or slider within its full range. The full range of each parameter may differ from synth to synth, so use your ear.
