After receiving his BS in molecular biology from Caltech in spring of 1970, Dave entered grad school at UC Santa Cruz, where he discovered his passion when his advisor, Dr. Harry Noller, introduced him to the Moog Synthesizer.  That December, E-mu Systems was christened.  Joining with high school friend Scott Wedge, Dave proceeded to build a company that became known for its unique instruments and advanced technology.  During E-mu’s early years, Dave corresponded and occasionally met with Bob Moog; a friendship he still treasures.

At E-mu, Dave was responsible for many of the innovations that remain mainstays of the synthesizer world.  He invented the polyphonic synthesizer keyboard, was the first to use a microprocessor in a music product, and pioneered the architectures and DSP algorithms that continue to power sampling instruments..

Dave designed most of the SSM family of synthesizer chips used in the Prophet 5, Korg Polysix, Korg Mono/Poly, Fairlight II, PPG Wave 2 and many others.  He also collaborated with many other early synth pioneers, including Tom Oberheim, Dave Smith, Roger Linn, Evan Brooks, and Peter Gotcher.

When Creative Labs acquired E-mu Systems in 1994, Dave became their Chief Scientist, continuing to invent DSP chips, algorithms and analog circuits for music and sound.

From 2011-2015 he served as Senior Director of Architecture at Audience, Inc, where he orchestrated the design of complex multi-core audio DSP chips for mobile phones.

Today, Dave continues to pursue his passion, designing new synth chips for Sound Semiconductor, creating new instruments and modules for Rossum Electro-Music, and inventing circuits and algorithms for Universal Audio, where he serves as a Technical Fellow. He holds over 40 US patents, with more pending.

When not designing synthesizers, he SCUBA dives, runs marathons, and backpacks in the High Sierra with his beloved standard poodle, Lily.  He lives in Santa Cruz, California, with his wife Karen.
