There are two founding traditions in modular synthesis and most people have only played one. Moog’s is the one that won commercially: a keyboard, a filter with a resonant character people learned to love, and a signal path that maps onto how Western music was already notated.
Don Buchla’s is the other one, and it is the one that most of what we cover descends from.
Hainbach — the German synthesist whose channel is one of the best resources on obsolete and institutional electronic music equipment — spent a residency at EMS Elektronmusikstudion in Stockholm with an unusual set of instruments: an exact replica of the System 100, an original System 200, a large mixed System 200 configuration, and the newer System 200e.
58 minutes. He describes the experience as “travelling through time.”
There is also a companion album, Buchla Stories, released pay-what-you-want.
Why these three systems in one room is rare
Buchla instruments were built in small numbers, mostly for institutions and a handful of composers, and they have become both expensive and fragile. Having a 100, two 200s and a 200e in one studio is a situation that exists in perhaps a few places in the world — and EMS Stockholm is one of them, because it is one of the great surviving institutional electronic music studios, in continuous operation since the 1960s and still functioning as a residency facility.
That institutional context is not incidental. The Buchla 100 series existed because the San Francisco Tape Music Center commissioned it, with Rockefeller Foundation money, in 1963 — Morton Subotnick and Ramon Sender asking Buchla for an instrument rather than a studio full of oscillators. Institutions are why these instruments exist and why any of them still work.
What makes a Buchla a Buchla
For anyone whose modular experience is Eurorack, the differences are not cosmetic and they are the reason the lineage matters.
No keyboard. This is the famous one and it is a design argument, not an omission. Buchla’s view was that a keyboard imposes twelve-tone equal temperament and a note-on/note-off model of music, and that electronic instruments need not inherit either. Instead you get touch plates — capacitive surfaces, pressure- and position-sensitive, with no discrete pitches — and sequencers, and voltage sources.
The consequence is that Buchla systems push you toward continuous gesture and evolving process rather than melody. A very large amount of the installation and generative work this publication covers is downstream of that decision.
Banana jacks for control voltage, tiny jacks for audio. Buchla used physically different connectors for control and audio signals. You cannot patch a CV into an audio input by accident — but more importantly, banana jacks stack, so one output can feed many inputs without a multiple. The system’s cabling encodes a distinction between the two domains, which is a conceptual commitment expressed in hardware. (Eurorack’s single 3.5mm standard makes the opposite commitment: everything is a voltage, do what you like.)
Modules that are processes, not components. A Moog system has an oscillator, a filter, an envelope. A Buchla system has the Source of Uncertainty (correlated and uncorrelated random voltages), the Arbitrary Function Generator, the Multiple Arbitrary Function Generator, and the 200e’s Quad Dynamics Manager. These are higher-level musical ideas rather than textbook signal-processing blocks, and they encourage you to think about behaviour rather than about signal flow.
And complex oscillators. The Buchla 259 and its descendants put a principal oscillator, a modulation oscillator and a wavefolder in one module — a complete FM-and-waveshaping voice rather than a sine source. The entire “complex oscillator” category in modern Eurorack, including Make Noise’s DPO and Mutable’s Braids lineage, traces here.
100 to 200 to 200e is the arc worth hearing
System 100 (1963–66) — the original commission. Discrete transistor circuitry, the first sequencers, and the instrument Silver Apples of the Moon was made on. Historically enormous; sonically rawer than people expect.
System 200, the “Electric Music Box” (1970s) — the mature design. The 259 complex oscillator, the 266 Source of Uncertainty, the 281 quad function generator. This is the system most of Buchla’s reputation rests on, and the one most contemporary modules are imitating.
System 200e (2004 onwards) — digitally controlled analogue, with preset recall and MIDI. The controversial generation: it brought memory to a tradition built on the unrepeatable, which some people regard as a betrayal and others as the obvious next step. Worth hearing next to the 200 for exactly that reason — and worth noting that the problem the 200e was solving is the same one the Adamsynths Warthog is attacking twenty years later.
Why watch 58 minutes of it
Because there is almost no good comparative documentation of these instruments, and the ones that exist tend to be either reverential or technical. Hainbach’s channel is consistently good at the thing that is hardest to get from a manual: what an instrument makes you do.
And because the Buchla tradition is the direct ancestor of generative, process-based and installation sound work. If you build pieces that run by themselves and evolve, you are working in a lineage that starts with a man who deliberately refused to put a keyboard on it.
For more in this territory, we covered Suzanne Ciani’s 1976 Buchla cookbook being released free earlier this year — which is the best primary document on how one of the greatest Buchla players actually patched.
