Underdog Electronic Music School Unleashes the Chirpy Filter Mayhem

Let’s kick things off with a sound that’s fresher than a morning magpie chorus—filter self-oscillation. Underdog Electronic Music School dives straight into the chirpy, bleepy world where filters sing without any input, just pure resonance mayhem. These tones are delicate, playful, and as lively as a possum in a fruit bowl, giving your tracks that unmistakable wet, blippy vibe.

If you’ve ever wanted your synth to sound like a flock of birds or a bubbling creek, this trick’s your ticket. By cranking the resonance until the filter self-oscillates, you get those pure, sine-like tones with a bit more muscle. It’s a classic move, but when done right, it’s as satisfying as nailing a sausage sizzle on the first go.

The real fun starts when you sequence that self-oscillating filter. Here, Underdog uses a Moog synth with all mixer inputs shut, letting the filter’s high resonance do the heavy lifting. The Moog DFAM steps in as the sequencer, sending out those bleepy, melodic patterns that dance around like kangaroos on a trampoline.

Turn down the resonance and you’re left with silence—crank it up and you’ve got a playground of pure, juicy tones. Toss in a bit of delay, and suddenly those simple sequences turn into lush, evolving soundscapes. It’s a dead-simple setup, but the results are anything but boring.

Now, if you’re after something a bit more unpredictable, Underdog shows how external sequencers can spice things up. By chaining step sequencers and muting steps, you get rhythms that are as wobbly and exciting as a surfboard in a rip. The Moog DFAM’s tempo gets split and shuffled, making the sequence loop in a beautifully unstable way.

Layer in some warmth, and you’ve got a groove that’s both hypnotic and a little bit wild. This approach is perfect for those who love their beats with a side of chaos—think outback storm, but with synths instead of thunder. The textures become richer, and the groove takes on a life of its own.
