Stylophone CPM DF-8 Dynamic Multi-Filter

Imagine a filter that doesn't just shape sound—it generates chaos from thin air, thanks to its pair of built-in white noise sources that can self-oscillate into wild tones all on their own.

This dual analog filter powerhouse packs eight modes per channel, blending Stylophone's gritty GEN R-8 (12dB/oct multimode: lowpass, bandpass, highpass, notch) with a classic 2045 recreation (24dB/oct lowpass), plus hybrid beasts like Bandpass+, Notch+, and Bandstop+ for everything from silky sweeps to screaming distortion. Two ADSR envelopes (linear or exponential) drive VCAs with inverters, triggered via gate/CV, audio threshold, manual button, or autorepeat LFO mode, while a sample-and-hold with slew, three envelope attenuverters, and a modulated PT2399 delay add endless modulation via the 14 patch points and mod matrix. Housed in a rugged 42HP Eurorack-ready desktop with side ribs for locking multiple CPM units together, it runs on 6 AA batteries, Eurorack bus, or PSU, with a 2W speaker, 3-into-1 mixer, stereo 1/4" outs, and headphone jack for instant portability.

Since its November 2025 release, players love how it pairs perfectly with the CPM DS-2 for a compact analog voice, praising the raw, dynamic filters and hands-on knobs that make sound design feel alive and immediate.
