Today’s article is one for the knob twiddlers.
In the modular synth world there’s an ace case study of a different kind of value; not just market value, but community value.
For those of us with a few choice Mutable Instruments (MI) modules in our racks, Behringer’s new HALOS is a particularly interesting piece of news. Behringer has released a clone of the legendary Mutable Instruments Rings physical modeling module, for a fraction of the price.
On the surface, and often said of Behringer, this might seem like a simple story of a larger company leveraging a popular design for profit. But this is where the genius of Émilie Gillet’s original ethos comes into play.
The Power of Open-source Licensing
Long before she made the decision to stop production and wind down MI, Émilie had a core philosophy rooted in her academic background: sharing knowledge is paramount. She made the schematics and software for all her modules open-source. This meant that anyone, from a hobbyist DIYer to another manufacturer, was free to use, learn from, and even replicate her designs.
This ethos created a vibrant ecosystem of third-party builders and clone makers, ensuring that her designs would live on and remain accessible to musicians long after her own company ceased production.
So, when a company like Behringer releases the HALOS, provided the relevant open-source licence terms are complied with, a clone based on the Mutable Instruments designs would generally not constitute IP infringement. It is, in fact, an example of Émilie’s license doing exactly what it was designed to do: spread her creations as widely as possible.
Wouldn’t Open-Source devalue the brand?
Value Isn’t Always About Exclusivity: By prioritising knowledge sharing over proprietary lock-in, Émilie created immense value for the entire modular community and the MI brand. She wasn’t just selling a module; she was selling an idea, a design, and a sound that she wanted everyone to have access to.
The Original Has Enduring Value: While the Behringer clone offers an affordable entry point, many in the community still value the original for its build quality, brand prestige, and the connection to the creator herself.
Two Business Models, Both Valid: The Behringer model is about mass production and affordability, making classic designs accessible. The MI model was about innovation and community-driven, OS creation. Both have a place in the market, but the latter’s legacy is defined by a generosity that has fundamentally shaped the modern Eurorack landscape.
In the end, while the HALOS might not carry the iconic Mutable Instruments name, its very existence is a testament to the power of Émilie Gillet’s vision. It’s a reminder that a well-chosen license (and a clear understanding of the terms), based on clarity and a strong philosophy, can be one of the most powerful and enduring assets a company, or a creator, can have.
