NAMM 2025: Stylophone’s CPM DF-8 is a ‘beauty and the beast’ filter that can purr or squeal, but that’s only half the sound design story

Stylophone CPM DF-8.

NAMM 2025: Following the news that the DS-2 synth is now available, Stylophone has confirmed a second product for its ‘Compact Portable Modular’ (CPM) range in the form of the DF-8 filter unit.

Coming in the same brutish-looking form factor as the DS-2, this includes both an emulation of the smooth 2045 low-pass filter and Stylophone’s dirtier Gen R-8 filter, creating a device that the company says has ‘beauty and the beast’ vibes.

While the 2045 filter has just a single low-pass mode, the R-8 can be run in low-pass, band-pass, high-pass and notch configurations. When the two filters are combined you get three additional modes: Bandpass+, Band Reject+ and Notch+.

You can access any of these modes in each of the two channels, and these are controlled by a pair of ADSR envelopes. Trigger options include gate a signal, an audio signal threshold and a manual trigger button, while there’s also an auto-repeat mode that works like an LFO.

The DF-8 isn’t just a dual filter unit, though. Additional features include two white noise sources, a Sample & Hold modulation source with adjustable slew, and a PT2399 delay with modulation. This gives it some serious sound design potential, whether you want to add subtle atmosphere or dial in the craziness.

As you’d expect, the DF-8 is designed to work well alongside the DS-2 - in fact, you can physically lock the two together using the built-in side ribs. You can also use it as part of a Eurorack system, or anywhere else you fancy. Power can come from batteries, an external PSU or a Eurorack power bus, and there’s a built-in 2W speaker so you’ll never be caught short of an ‘out loud’ listening option. Stereo outputs are here too, of course.

While the DF-8 will be showcased at NAMM, it won’t actually be available until later this year. Pricing is still to be confirmed.
