Adrian Freed is a researcher, inventor, and educator whose pioneering work has fundamentally shaped the fields of computer music, interactive systems, and new interfaces for musical expression. He is best known as co-creator of Open Sound Control (OSC), a communications protocol now used worldwide in multimedia applications, and for developing the first Digital Audio Workstation.
Adrian Freed served as Research Director of UC Berkeley's Center for New Music and Audio Technologies (CNMAT) from 1991 until his retirement in 2016. During this time, he organized an ambitious research agenda that produced concrete, practical developments in music-related technologies that have been widely adopted by researchers, artists, and companies worldwide.
His work bridges mathematics, electronics, and computer science to create innovative audio, music, and media production tools. From the earliest graphical user interfaces for digital sound editing to modern e-textile controllers and augmented instruments, Adrian has consistently pushed the boundaries of what is possible in musical interaction and sonic expression.
After CNMAT he led research and development at nOmni (2017–2020), including custom IC design with 14 working ICs, and in 2018 was research ethicist for Flex-ability.org. Since November 2020 he has been a Senior Software Engineer at Adobe.
Co-created with Matt Wright in 1997, OSC has become a fundamental protocol for communication among computers, sound synthesizers, and multimedia devices. It is now the standard in computer music and interactive media communities worldwide.
Developed MacMix, a pioneering interactive sound editing, processing, and mixing system, which was commercialized by Studer-Editec. This laid the groundwork for all modern DAWs.
Created the first audio plug-in system in 1986 with MacMix's "UserHooks," establishing the paradigm now used in all professional audio software.
Developed widely-used tools for Max/MSP, SDIF (Sound Description Interchange Format), and odot programming objects, which are used by researchers and musicians globally.
Leader of CNMAT's Guitar and Chordophone Innovation Group (GIG), pioneering hexaphonic sensing, augmented electric guitars, cellos, and novel fingerboard instruments.
Pioneered interactive textiles and fabric sensors for musical controllers, including the Tablo fabric drape sensing controller and numerous e-textile innovations.
Established and led high-fidelity-prototype driven research as CNMAT's signature methodology: building working instruments and apparatus reliable enough for live performance, semester-long teaching, and decade-long research arcs. This stance produced durable artifacts (MacMix, Reson8, HTM, OSW, the Connectivity Processor, the Icosaspeaker, Slabs, the Augmented Cello, the Paper FingerPhone, OSC, odot, Flex-Ability toolkit).
Four decades of continuous engagement with machine learning, from teenage experiments with electronic neural-network simulations and symbolic AI in 1970s LISP, through CNMAT's perceptually-grounded ML research program (real-time neural nets for instrument control, neuro-fuzzy systems, SVM gesture estimation, an early-1990s vision for analog VLSI neuromorphic computation, and the Terraswarm machine-improvisation work), and now into generative AI at production scale: currently delivering high-fidelity reference implementations, prototypes and production systems for Premiere Pro, Firefly, and Sensei integrations at Adobe.
Adrian is a highly acclaimed educator, teaching workshops and classes on Arduino, electronics, e-textiles, music technology, and interactive systems. Students consistently praise his gift for making complex topics accessible and his ability to inspire creative exploration.
His teaching philosophy emphasizes hands-on learning, interdisciplinary thinking, and the importance of understanding both the technical and artistic dimensions of music technology. He has taught at institutions worldwide and mentored countless students who have gone on to create innovative work in music technology and interactive art.

Adrian's journey into music technology began in Australia, where he learned UNIX at university. In the 1980s, he worked at IRCAM (Institut de Recherche et Coordination Acoustique/Musique) in Paris, one of the world's leading computer music research centers. There, working under Pierre Boulez and alongside David Wessel, he developed his deep expertise in audio systems, recording techniques, and computer music infrastructure.
His experiences at IRCAM, including late-night recording sessions with jazz legends like Steve Lacy and innovative work on the first digital audio workstation, laid the foundation for his lifelong commitment to combining rigorous technical innovation with musical and artistic excellence.
