Knobcon 2025: WMD Cosmic Debris is a new performance-oriented delay reverb powerhouse module in collaboration with Infrasonic Audio.
The majority of companies that develop and sell Eurorack modules are small companies with a few employees, often one-person operations. Many draw their strength from the close community, which has led to lovely collaborations.
The latest Eurorack collaboration was unveiled at Knobcon 2025. WMD has teamed up with Infrasonic Audio, developer of the Warp Core, for the new Cosmic Debris module.
WMD Cosmic Debris
Cosmic Debris is a new performance-oriented delay and reverb powerhouse module built for modular explorers who want more than echoes.
Cosmic Debris began as a design by Nick Donaldson of Infrasonic Audio, a fellow Denver modular enthusiast we met through our monthly Freq Boutique gatherings.
Nick approached WMD for advice on manufacturing, and as soon as we heard the sounds he was creating, we knew there was something special. The process has been as rewarding as the results: not only has Cosmic Debris grown into a truly versatile delay and reverb processor, but we’ve had the joy of building a deeper friendship through the design journey.
At the WMD Cosmic Debris core is a newly developed engine with 16 interactive delay lines. You can tweak them with the usual parameters, including pre-delay, time, rate, and feedback.
The module offers flexible sync options, including clock input, tap tempo, or free-running modes. That’s the classic stuff, but the module goes far beyond what a usual delay can do.
The spray knob transforms the delay taps into lush ambient reverbs, while Scatter, the parameter right next to it, reshapes the delay feedback paths and interactions between lines. This creates evolving textures with a twist on the knob.
Deep Delay Transformation
Then, in the middle, you can infuse modulation into the time with the dedicated parameter, resulting in various flexible motion effects. This goes from analog-style warble, subtle movement in time, up to heavy randomized pitch fluctuations.
A built-in band-pass filter lets you carve space in the mix or push the signal into motion with CV modulation. A dedicated Freeze function captures audio into a timeless loop, allowing you to hold textures indefinitely.
That’s not all. WMD Cosmic Debris also features three unique processing modes: blur, ratio, and warp, expanding the palette even further, from smearing reverbs to pitch-shifted delays. There also seems to be an intriguing glitch function, but there are no details yet as to what it does.
At the connection side, you have stereo I/O on 3.5mm mono sockets, and CV control over the majority of the features. Special attention should be paid to the gate input with its three modes: blast, freeze, and glitch.
Blast delivers a momentary boost into the delay input as well as 100% send level (in send mode) for explosive bursts of sound with natural tails.
There is also a send mode that turns mix control into a CV-controllable send/return level, perfect for insert-style processing

First Impression
All details aren’t known yet. However, there’s a short sound snippet on Instagram that already sounds very promising. One thing is sure: it’s a very mighty delay module that is coming to market soon.
WMD Cosmic Debris is now in production and is ready for pre-order for 483,95€
