Superbooth 2026: Make Noise Plexiphon is a new stereo spatial texturizer module in collaboration with Soundhack that blends between reverb and multi-tap echo.
The New Universal Synthesizer System, or NUSS for short, has grown into an exciting package over the past months. I don’t think it’s quite finished yet, but it can already be considered a system.
To further refine the sounds of NUSS or any other system, Make Noise invited people to their Superbooth 2026 booth to see the new Plexiphon FX module.
What Is Make Noise Plexiphon?
Plexiphon is a new stereo FX processor and the latest collaboration between Make Noise and Tom Erbe (soundhack). It’s not very traditional, as it’s neither a reverb nor a delay, and it doesn’t intend to be.
Instead of being one thing, it morphs continuously between reverb and echo, creating unique in-between results. Make Noise and soundhack describe it as a “modeless spatial texturizer,” and that description holds up well.
Classic FX processors feature a multitude of switchable algorithms and other features. Not here. You explore both worlds fluidly in a continuous sonic space, without switching between algorithms or mode-based thinking.
Familiar patterns like hall reverb, shimmer reverb, multi-tap delay… are not available here. It awakens the user’s creativity and curiosity to explore this space. And of course, all this exploration is fully voltage-controllable.
The Controls
At the Plexiphon core is the Plexus control, which simultaneously modulates the number of feedback paths in the algorithm and their entanglement.
Then, the big SIZE parameter, almost in the middle, determines the relationship between those paths, operating like a “delay time,” or a “room size,” at either extreme of Plexus. One of the primary parameters that makes this processor so fascinating
Diffuse and Color offer control over texture and timbre over time, from soft to sharp and from bright to dark. So the section that modifies the character. Things get more interesting in the stereo parameters, Couple and Skew.
Couple determines to what degree the left and right sides are isolated or intermingled. This goes from dual mono to fully interlaced stereo.
Skew, on the other side, offers simultaneous inverse or tandem control of the left and right paths on the Plexus, Size, and Color parameters. An exciting approach to achieving stereo movement that goes far beyond what bread-and-butter effects can do.
The Send gate input determines whether and when the input signal gets fed into the Plexus, perfect for dub echo effects. The CV output provides an envelope follower signal that can be fed back into the Plexiphon’s own controls or elsewhere in the system.
Each parameter offers CV control via a dedicated attenuverter.
First Impression
With the Erbe-Verb, Make Noise, and Tom Erbe (Soundhack) raised the bar for effects in Eurorack. When the module was discontinued, many expected an Erbe-Verb 2. Plexiphon isn’t a successor; it’s a different beast with its own character and strengths.
I find the idea of not limiting the module to a fixed effect, but rather leaving the user free to explore creatively in this space, very clever and exciting. This also fits very well into the existing Make Noise module lineup.
How versatile the Plexiphon is will only become clear over time as users put the module into practice. The initial demos sound interesting. At times, it sounds very much like Karplus-Strong synthesis on steroids. Looking forward to more explorative demos.
Make Noise Plexiphon will ship in June 2026 and is available now for pre-order for $469/479€
