Claude Sonnet 5.5 vs MiMo v2.6 Flash

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.

Patchbay is a three-person studio in Rotterdam dedicated to the repair and restoration of vintage synthesizers. We work on instruments that have been sitting in attics, basements, and rehearsal rooms for decades — the ones that hum when they shouldn't, lose their voice, or refuse to power on at all. Our approach is patient and detail-oriented. We trace faults through aging circuit boards, source period-correct components when possible, and treat every repair as a conversation with the person who built the instrument, and the musicians who played it before it fell silent.

We believe these machines deserve to stay in circulation rather than end up in landfill. Whether it is a Moog, a Juno, or a machine you cannot name, bring it in and we will tell you honestly what it needs.
