"🎛️ Djupviks Spektrum: The Filter That Clocks Itself 🎛️

Spektrum isn’t just another Eurorack filter. It’s a switched capacitor stereo filter that uses your input signal as its clock, turning audio into rhythmic glitches, stutters, and pulsing textures you won’t find anywhere else.

In this video, we break down:
✅ What a switched capacitor filter actually is (in plain English)
✅ How Spektrum turns your audio into patterns and sequences
✅ The unique stereo behavior and control layout
✅ Patch examples to unleash Spektrum’s chaotic beauty

Spektrum reacts to everything you feed it — arpeggios become glitchy basslines, noise turns into crunchy percussion, and waveforms transform into evolving rhythmic patterns.

If you’re looking to add a truly unique, reactive, and chaotic filter to your rack, Spektrum might just be the perfect machine.

Spektrum is available to buy as a kit from Thonk in the UK and Europe, SynthCube and Modular Addict in the US. SynthCube will be stocking some pre-built versions soon too.
