Remaking the drone synth from the 2020 song "Children of the Omnissiah" by Warhammer 40,000 OST can be an exciting challenge for any synthesizer enthusiast. Here’s how you can create the "Children of the Omnissiah" drone 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
“Children of the Omnissiah” from the Warhammer 40,000: Mechanicus original soundtrack, composed by Guillaume David, combines dark ambient textures with industrial soundscapes to create an unsettling atmosphere befitting the grimdark universe. The track features a massive bass drone synthesizer built from a heavily filtered saw wave with unison voicing that creates a rumbling, pulsating foundation beneath the mix. This drone employs slow portamento for pitch bending between notes and is drenched in heavy reverb to achieve its cavernous, space-filling presence that reinforces the mechanical and otherworldly themes of the Adeptus Mechanicus. You can hear this booming bass drone become prominent at 0:17 in the song, where it establishes the ominous low-end that carries throughout the composition.

- 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.
