Patchbay is three people in a workshop in Rotterdam, trying to keep old synthesizers alive. We repair, restore and recalibrate the instruments that shaped electronic music: Moogs and Oberheims, Rolands and Sequential Circuits, the odd temperamental Soviet oddity that someone found in an attic.
Most of what lands on our benches has been silent for years. A crackling pot, a drifting oscillator, a power supply that gave up in 1994. Some come from working musicians who need their instrument back before the next tour. Others come from people who inherited a dusty box from a parent and want to hear what it sounds like.
We work slowly and by hand. We trace faults with a scope and a schematic, source or rebuild parts when originals are gone, and change as little as we can. Every synth leaves with a note describing exactly what we did, so the next person to open it knows where we have been.
Come by, bring your synth, and stay for coffee.
