The Unperson’s Filter Rumble: From Sine Slices to Stereo Mayhem

Let’s not kid ourselves—filters are the muscle in your synth rig, shaping your sound whether you’re tweaking in the studio or sweating on stage. The Unperson wastes no time reminding us that filters aren’t just for polite subtractive synthesis—they’re the backbone of sound design and live performance, slapping character onto every patch.

Right from the off, we’re told there’s a dizzying array of filter flavours out there, each with its own attitude. This isn’t a history lesson; it’s a call to arms for anyone who wants their tracks to punch through the mix. If you’re still treating your filter as a glorified tone knob, you’re missing the point—and probably half the fun.

The Unperson dives straight into the filter pit, demoing how a low pass filter slices off the top end, leaving only the bass to rumble. Crank the cutoff down and you’re left with a subby throb; push it up and the highs come screaming back. High pass does the opposite—think of it as a sonic scalpel, carving out mud and letting your hats and fizz shine.

Resonance gets its own moment in the spotlight, adding harmonics and that classic squelch we all crave. The Unperson’s hands-on approach means you hear the difference, not just read about it. And if you’re after that sweet spot where the filter sings, you’ll want to watch the video—words can’t do justice to the harmonics blooming as resonance climbs.

Modulation is where filters go from polite to feral. The Unperson patches up envelopes using Make Noise Maths, showing how attack and release can turn a static sound into a living, breathing groove. Reverse envelopes? Yes please—perfect for tension and those cheeky build-ups.

Then it’s LFO time. Sync them to your sequence and suddenly your patch is pulsing, wobbling, and generally causing trouble. The Unperson’s not shy about pushing the modulation into weird territory, and if you want to see how rhythmic filter sweeps can get, you’ll need to watch the hands-on patching in the video. This is where the magic happens, and no text can capture the groove of a filter being modulated within an inch of its life.

Now we’re talking big-league filter action. The Unperson brings out the Vostok Atlas—a four-filter beast—and shows how running different filter types in parallel can turn a simple sequence into a shifting, multi-dimensional monster. Modulate the scan control and you get rhythms that would make a breakcore producer blush.

The Make Noise QPAS gets a special mention for its smile pass output and stereo filtering. Forget vanilla left-right panning—this is about sculpting space with independent frequency control on each side. The Unperson hammers home that every filter has its own flavour, and modular lets you pick your poison. If you want to hear what a smile pass does to a mix, you’ll need to catch the video—words can’t paint the stereo picture this thing creates.
