Patchbay is three people, one workbench, and a room in Rotterdam full of machines waiting to sing again. We met in a repair queue, argued about capacitor brands, and never quite stopped. Between us we hold about forty years of solder smoke: poly synths with dead voice boards, tape echoes turned to tar, modular systems grown quiet behind their patch points. We work slowly and in the open. Every fault is traced before a single part is ordered, every change is written down, and nothing leaves the studio sounding less like itself than when it arrived. Restoring a vintage synthesizer is not nostalgia. It is keeping a specific instrument, with a specific voice, in the hands of the people who play it. If yours is one of them, bring it in. We will tell you honestly what it needs, what it costs, and how long it will take.
