About Seaweed Audio

Why Fathom?

Seaweed Audio was started in January of 2014 in order to create a new fully modular software synthesizer that meets the demands of today’s electronic musicians and producers.

As a musician myself, I’ve used many great software synthesizers over the last few years, but I often found myself running up against limitations built into their architecture as well as problems with audio quality.

Electronic music is now demanding more out of a software synthesizer in terms of versatility and audio quality, especially in the areas of modulation and original waveform development. 

Despite the staggering number of synths now available, I found that very few of them were truly modular, or could provide professional studio sound quality, and virtually none of them provided any serious tools for original waveform development.

Fathom was created to address these demands, and is well on its way to becoming the perfect tool for musicians who want to create completely original waveforms.

A Message from The Founder

Everett Sellner


I began studying classical piano at age five and started programming in high school in 1982 on a Commodore Pet using DOS BASIC.

I graduated in 1989 from Virginia Tech with a B.S in Electrical Engineering. My first job out of college was at Nortel debugging embedded firmware for central office phone switches. 

In 1997 I attended the Los Angeles Recording School and graduated with a technical degree in Audio Engineering.

During the following year I worked in several major L.A. recording studios, including Ocean Way on Sunset Blvd, Record One and Rumbo Recorders in North Hollywood. 

Some of the bands I worked with at the time as a runner included the Rolling Stones, Neil Young, Green Day and the famous producers Jack Joseph Puig and Ry Cooder. 

Between 1998 and 2001 I wrote embedded firmware for electronic keyboards at Ensoniq. 

Since then I spent most of my time back in Los Angeles working in medical device software, which included mostly C++ and C# development for wireless communication protocols and user interface design for medical programmers. 

In January of 2014 I started designing Fathom which took three years to develop prior to its first release in April of 2017.
