ricursiveAI/Ripple-65B-Preview vs Gemini 3.8 Flash

Patchbay is three people and a bench in Rotterdam. We repair vintage synthesizers of all kinds, from a Moog that needs one capacitor to a modular system that hasn't been run in thirty years.

We started because older instruments deserve to keep working. The circuitry is simple, but the failures are personal: a dead pot in a favourite key, a CV rail that drifts, a ribbon controller that was saturated in smoke. We treat each case the way our own instruments would need to be treated.

A workshop is a good place for slow work and long conversations. We're always glad to open a system on the bench, find out what it actually needs, and explain why. If you have something unwell, send it over or come visit us in Rotterdam.

Tucked away in Rotterdam, Patchbay is a three-person repair studio dedicated to the preservation and revival of vintage synthesizers. We believe that classic instruments are living machines rather than museum relics—tools built to inspire, create, and be played loud. Between the three of us, we combine decades of experience in electronics engineering, sound design, and meticulous craftsmanship. Whether tracking down elusive voice chips for an eighties polyphonic giant, rebuilding power supplies, or recalibrating the drift on a cantankerous monophonic circuit from the seventies, we treat every piece of gear with obsessive attention to detail. Our workbench is built on a deep respect for historical engineering and a refusal to cut corners. For musicians, producers, and collectors across the Netherlands and beyond, Patchbay is where forgotten circuits find their current again, keeping the tactile soul of analog synthesis alive and resonant.
