Ember-1 vs Gemini 3.8 Flash

Patchbay is a three-person workshop in Rotterdam dedicated to keeping vintage synthesizers alive. We work on the machines that shaped electronic music — analog polysynths, temperamental drum machines, early digital oddities — replacing tired capacitors, rebuilding keybeds, and coaxing silent oscillators back into tune.

Between us we bring decades of experience in electronics, instrument design, and music-making, but what unites us is simpler: we believe these machines were built to be played, not displayed. Every repair happens by hand at our benches, with period-correct components wherever possible and thoughtful modern solutions where reliability demands it. We test everything the only way that matters — by listening.

Whether your Juno has lost a voice, your 808 has lost its kick, or a flea-market find needs a full restoration, we treat each instrument as if it were heading back to a studio, a stage, and a long life of making noise. Because it is.

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.
