Gemini 4 Carbon vs Claude Fable 5.1

Tucked away in a bright workshop near the Rotterdam docks, Patchbay is a three-person studio dedicated to keeping electronic music history alive. We repair, restore, and calibrate vintage synthesizers, drum machines, and outboard gear. Whether it is a temperamental Juno with failing voice chips, a road-worn Minimoog drifting out of tune, or an obscure polysynth needing a complete overhaul, our benches are built for machines that make noise.

Between the three of us, we combine decades of experience in electronics, sound design, and obsessive troubleshooting. We do not view classic synthesizers as fragile museum pieces meant to sit behind glass; they are working instruments built to be played, patched, and pushed to their limits. Armed with original schematics, precision test gear, and a deep respect for analog circuitry, we bring tired hardware back from the brink—ready for another forty years in the studio or on stage.

Patchbay is three people and one workshop in Rotterdam, and we spend our days bringing old synthesizers back to life. Most of what arrives at our bench is somewhere between thirty and fifty years old: a Juno with a dead voice chip, a Minimoog that drifts out of tune the moment the room warms up, a Polysix whose battery has quietly eaten its own circuit board. We know these instruments inside and out because we have had hundreds of them open on the table.

We started Patchbay because we kept meeting musicians who had been told their synth was not worth fixing. We disagree. These machines were built to be serviced, and with the right parts, enough patience, and a good set of schematics, almost any of them can be made to play again. When we hand an instrument back, we want it to sound the way it did the day it left the factory, or better.
