NAMM 2025: Stylophone CPM DF-8 is a new patchable stereo analog filter box with modulation and crunchy delay.
At NAMM 2024, Dubreq introduced the Stylophone CPM, a new series of compact, portable, modular products. The first product in this series is the CPM DS-2, a two-voice analog drone synthesizer, which has just started shipping.
Dubreq is expanding the CPM series for NAMM 2025 with the new Stylophone CPM DF-8 filter box.
Stylophone CPM DF-8
The new Stylophone CPM DF-8 is a new patchable stereo analog filter box with modular connectivity. It comes in the same shape and black design as the DS-2 drone synth. It’s so similar that you must look twice to see the difference.
CPM DF-8 features two identical rich-featured self-oscillating filter channels. Each channel consists of eight distinct filter types: four of the proprietary GEN R-8 filters (12dB/oct) with lowpass, bandpass, highpass, and notch modes.
Then, it hosts a soft-sounding 2045 lowpass filter recreation and three combination types with 12dB and 24dB/oct slopes with bandpass +, band reject +, and notch + modes. This is a colorful selection of analog filters. The filters can be tweaked manually with classic cutoff and resonance parameters.
You can use the filters independently as two mono filters with dedicated volume controls or link them as stereo filters.
Modulation
In addition to the two filter channels, the Stylophone CPM DF-8 offers advanced modulation. It has two standalone ADSR envelopes with linear and exponential responses and four envelope trigger/gate modes, including an auto-repeat AR envelope loop mode.
Nice to see is that they have also implemented three envelope depth attenuverters, making them more flexible.
Unfortunately, the CPM DF-8 does not have LFOs, but you can switch the envelopes into pseudo-LFOs. Next to this is a sample-and-hold modulation source with sync input and adjustable slew. Two VCAs with envelope inverters and two white noise sources with volume controls are also onboard.
Switches can assign the modulators directly to the respective filter. Alternatively, you can delve deeper by patching the features using the 14 patch points. Each filter has its own set of inputs and outputs, which is neat. So you can use them as two standalone filters.
Crunchy Delays
There is one more thing for sound explorers. Stylophone CPM DF-8 also hosts a vintage PT2399 tape-style delay with modulatable time parameter (s&h or envelope II) for crunchy delay.
The new CPM DF-8 is both a standalone stereo analog filter and a 42HP Eurorack module. It can be operated in standalone mode with 6 AA batteries or a power supply. It also has a small 2-watt speaker, which is certainly not enough to provide sound for a party.
Finally, it has two stereo sockets (line level/headphone) that route the signals from the new Stylophone effects box in your external gear.
Stylophone CPM DF-8 First Impression
A very exciting second product in the new Dubreq Stylophone CPM series. I have been wanting more analog filter boxes for a long time, especially stereo. This one does that and offers even more. I’m looking forward for more demos and the official release.
The new Stylophone CPM DF-8 Dual Analog Filter Unit will be showcased at NAMM Booth 10407 and available later in 2025—pricing to be confirmed. You can join the waitlist on the official website.
