Patchbay is a three-person studio in Rotterdam devoted to the repair and restoration of vintage synthesizers. We work on the machines that shaped the sound of the last fifty years — Roland, Moog, Yamaha, Korg, EMS, and the rest — from the rare and legendary to the well-loved and well-worn.
We started the studio because these instruments matter. They were built to be repaired, with discrete components, schematics, and construction that reward patience and care. Somewhere along the way, that way of making things fell out of fashion. We think it's worth keeping alive.
Every synthesizer that comes through our door is treated the same way: carefully diagnosed, honestly assessed, and repaired with respect for its original character. No unnecessary modifications, no shortcuts that compromise the instrument. Whether it's a failed voice chip, a dead key, or years of dust and neglect, our job is to put the machine back in the hands of the people who play it.
