Dave Smith, a name synonymous with innovation in electronic music, left an indelible mark on the world of synthesizers and music technology. His contributions, most notably the Prophet synthesizers and the creation of MIDI (Musical Instrument Digital Interface), fundamentally changed how music is created, performed, and experienced. Remembering Dave Smith means remembering the man who democratized access to powerful sound design tools and fostered collaboration between musicians and machines.

Early Life and the Birth of Sequential Circuits

David Joseph Smith was born in San Francisco in 1950. His interest in electronics began early, fueled by a fascination with circuits and sound. He studied computer science and electrical engineering at the University of California, Berkeley. It was during this time that his passion for synthesizers ignited. The existing synthesizers of the era, while groundbreaking, were often expensive, complex, and difficult to program.

In 1974, Smith founded Sequential Circuits. His initial focus was on designing digital sequencers, hence the name. However, his vision quickly expanded to creating a more accessible and powerful synthesizer. This ambition led to the development of the Prophet-5, a groundbreaking instrument that would revolutionize the synthesizer landscape.

The Prophet-5: A Polyphonic Revolution

The Prophet-5, released in 1978, was a game-changer. Prior to the Prophet-5, most synthesizers were monophonic, meaning they could only play one note at a time. While some polyphonic synthesizers existed, they were often complex and unreliable. The Prophet-5 was the first fully programmable polyphonic synthesizer, meaning that it could play multiple notes simultaneously and save sound patches in its memory. This innovation was a major leap forward, allowing musicians to create richer, more complex textures and easily recall their favorite sounds.

Key features that made the Prophet-5 revolutionary:

  • Polyphony: Five-voice polyphony allowed for chords and more complex harmonies.
  • Programmability: Sound patches could be saved and recalled instantly, eliminating the need to manually adjust knobs for each performance.
  • Analog Sound: The Prophet-5's analog circuitry delivered a warm, rich, and powerful sound that became instantly recognizable.
  • Ease of Use: Compared to earlier modular synthesizers, the Prophet-5 was relatively easy to program and use.

The Prophet-5 quickly became a favorite among musicians across various genres, from progressive rock and new wave to pop and film scoring. Artists like Kraftwerk, Talking Heads, Phil Collins, and John Carpenter embraced the Prophet-5, solidifying its place in music history. Its distinctive sound can be heard on countless iconic recordings.

The Creation of MIDI: A Universal Language for Music

While the Prophet-5 was a major success, Dave Smith recognized a growing need for standardization in the electronic music industry. Synthesizers from different manufacturers were incompatible, making it difficult to connect and control them. This limitation hampered collaboration and restricted the creative possibilities of electronic musicians.

In the early 1980s, Smith spearheaded the development of MIDI (Musical Instrument Digital Interface), a universal protocol that allowed synthesizers and other electronic instruments to communicate with each other. He collaborated with Roland founder Ikutaro Kakehashi to establish the standard. MIDI specifies a set of codes that represent musical notes, velocity, control changes, and other parameters. This allows different instruments to synchronize and exchange musical information seamlessly.

The impact of MIDI was profound and far-reaching. It transformed the way music was produced, performed, and shared. MIDI:

  • Enabled interoperability: Synthesizers from different manufacturers could now be connected and controlled by a single device or computer.
  • Facilitated sequencing: Musicians could use sequencers to record and edit MIDI data, allowing them to create complex arrangements without playing every note in real-time.
  • Revolutionized home recording: MIDI enabled home studios to become powerful production environments.
  • Opened up new creative possibilities: Musicians could experiment with new sounds and textures by combining different instruments and effects.

MIDI quickly became the industry standard, and it remains a fundamental technology in electronic music production to this day. Dave Smith's role in developing MIDI is arguably his most significant contribution to the world of music. In 2013, Smith and Kakehashi were awarded a Technical Grammy Award for their work on MIDI, recognizing its lasting impact on the music industry.

Sequential Circuits' Later Years and the Acquisition by Yamaha

Despite the success of the Prophet-5 and MIDI, Sequential Circuits faced financial challenges in the mid-1980s. The market was becoming increasingly competitive, with the rise of digital synthesizers and samplers. In 1987, Yamaha acquired Sequential Circuits. Smith worked at Yamaha for a short period, contributing to the development of new synthesizer technologies.
