Overview
Donald Buchla (1937–2016) developed voltage-controlled modular synthesis on the West Coast from 1963, in parallel with Moog and independently. He deliberately omitted the piano keyboard, using capacitive touch plates and sequencers instead, on the grounds that a keyboard imposes equal temperament and a note-based conception of music on an instrument that need not have either.

Steps
The problem as it stood
Electronic music composers at the San Francisco Tape Music Center wanted an instrument, and the available approach — tape manipulation — was slow. What that instrument should look like was entirely open.
What he actually did
Commissioned by Morton Subotnick and Ramon Sender, Buchla built the Series 100 with voltage-controlled modules, touch-sensitive capacitive plates, and sequencers as primary controllers. Subotnick's Silver Apples of the Moon, made on it, was the first electronic work commissioned by a record label.
How it worked
Technically similar to Moog's approach and philosophically opposed. Without a keyboard there are no discrete notes by default; pitch is continuous, and sequencers and random sources generate material rather than a performer playing tunes. It is designed for making sound, not for playing songs.
What it made possible
A whole tradition of American electronic music — Subotnick, Suzanne Ciani, Éliane Radigue on related instruments — concerned with evolving timbre and process rather than melody. The "West Coast synthesis" approach remains distinct and is actively built today.
What happened to him
He continued designing unconventional instruments and controllers for fifty years, always commercially marginal relative to keyboard synthesisers. He died in 2016.
Where the credit landed
Buchla and Moog arrived at voltage control independently and simultaneously, and Moog's keyboard-equipped version was vastly more commercially successful — so the popular story is that Moog invented the synthesiser. Buchla is separately profiled here because the divergence is a genuine design philosophy, not a failed competitor: he refused the keyboard on purpose, and that choice defined an entire alternative lineage.
Pro Tips
- No keyboard was a deliberate philosophical choice, not an omission.
- A keyboard imports equal temperament and a note-based conception of music.
- Moog and Buchla are parallel traditions, not a priority dispute.
Knowledge Base
What You'll Learn
The same technology, two incompatible ideas about what music is.
East coast and west coast synthesis
The shorthand is real. The Moog approach is subtractive: start with a harmonically rich waveform and filter material away, played from a keyboard, which suits notes and conventional structures. The Buchla approach favours complex oscillators, wavefolding and additive techniques driven by sequencers and random sources, which suits evolving texture and process. Both are voltage-controlled; they disagree about what the instrument is for.
Where This Fits
This guide covers one specific part of the history of media technology. The wider picture — how each link in the chain from capture through transmission to display was actually built, who built it, and why the credit so often landed somewhere else — is in A History of Broadcast Technology: The Chain From Capture to Screen, which frames the discipline as a whole and links out to the detailed guides underneath it, including this one.

FAQ
Q: Why did Buchla not use a keyboard?
A: He held that a keyboard imposes equal temperament and a note-based conception of music on an instrument capable of continuous pitch and evolving timbre. He used capacitive touch plates and sequencers instead.
Q: Did Buchla or Moog invent the synthesiser first?
A: They developed voltage-controlled synthesis independently and essentially simultaneously in the mid 1960s. Moog's keyboard version was far more commercially successful, which is why his name attached to the instrument.
