Sonoj Convention 2025
Music, Sound, and Tools You Won’t See Everywhere
18th and 19th October 2025, Cologne, Germany
Sonoj is the independent event for those who create music and sound with computers—whether recording real instruments or working with digital tools. Composers, producers, and sound designers come to refine their process, discover new tools, and share real-world experience by meeting up with real people.
No brands, no marketing—just people sharing self-made solutions, hidden gems, and free tools that deserve a wider audience.
Whether you record, compose, mix, or build your own instruments, software, or hardware, Sonoj is about technology serving creativity—not the other way around.
