Keith McMillen

Keith McMillen has been an innovator in audio and music technology for nearly 30 years. He has been working his entire adult life on one single problem – how to play live interactive music in an ensemble using extended instruments moderated by computer intelligence. This goal has required him to create dozens of new instruments, patented inventions and numerous successful companies in order to advance the technology sufficiently to reach his musical objectives. Keith began his audio career in 1979, when he founded Zeta Music. The company’s revolutionary electronic instrument designs created a new market in the music industry, and the brand Zeta is the “gold standard” for electric and electronic string instruments.

In 1992, as Vice President of Gibson Guitars, he founded and ran G-WIZ (an R&D lab for Gibson); and led the effort to devise ZIPI (a musical instrument control language that avoided many of MIDI’s limitations – ZIPI later evolved into OSC). Keith worked with UC Berkeley’s CNMAT and created a new technology group focusing on audio networking, synthesizers and string instruments. As Director of Engineering at Harman Kardon in 1996, he headed a division dealing with complex audio processing and distributed music networks.

In 1999, Keith founded Octiv, Inc. an Internet audio signal processing company that addressed the problem of inconsistent audio quality across disparate delivery platforms. Octiv produced the best selling “Volume Logic” plug-in for iTunes as well as fundamental advances in teleconferencing. He led the company as both technologist and business guru raising over $20M from VCs such as 3i and Intel Capital. In April of 2005, Keith sold Octiv to Plantronics (NYSE:PLT) and is personally funding the current operations of the BEAM Foundation.

Keith received his BS in Acoustics under James Beauchamp from the University of Illinois where he also trained in classical guitar and studied composition with Herbert Brun, Scott Wyatt and Sal Martirano. Keith has spent 25 years developing MAPPS – an integrated computer composition, notation and performance system.

Brian Wright - Electrical Engineer

Brian Wright - Electrical Engineer

Brian grew up in northern latitudes – beneath the Aurora Borealis, he began studying the mysteries of electrical machines at an early age. His navigations on the seas of technology and in applied audio-visual wizardry led inevitably to the Bay Area, where he tames wild circuits and transducers with KMI, and in his free time enjoys photography and the sonic arts.

Adi Handach - Electrical Engineer

Adi Handach - Electrical Engineer

Adi Handach is a hardware engineer at KMI, actualizing from idea to bread board to PCB the electronics that power our instruments. In his day-to-day you may also find him working on firmware, building relationships with parts and PCB manufacturers, and tying up other loose ends that come with working as a small team trying to bring big musical products to the world. Adi has always been interested in bringing people novel musical experiences, both from behind the drum set, which he has been playing since age 9, and from behind the electronics workbench. Since graduating with a Bachelor of Science in Electrical Engineering from Stanford University in 2017, he has dedicated his work and independent study time to furthering this cause, previously working as a hardware engineer for Moog Music on designing the Claravox Theremin product and making contributions to hardware upgrades of the Matriarch, Theremini, and Etherwave Theremin. He has been working full-time at KMI since April 2022, predominantly focused on the design of our EM Pro, 12 Step, and SoftStep products. We are pleased having him onboard and look forward to further tapping in to his skillset and learning ability in shaping the company and the coming products ahead.
