GLM 5.3 Flash vs Kimi K3

Patchbay began the way most repair shops do: with a broken synth, a stubborn owner, and a soldering iron that refused to stay idle. We're three people—Joris, Marit, and Tomas—working out of a small workshop on the back streets of Rotterdam-Noord, surrounded by oscilloscopes, spare parts, and instruments that sometimes arrive in worse condition than their owners admit.

Between us, we've spent decades repairing and restoring vintage synthesizers: Rolands, Moogs, Korgs, Yamahas, and machines whose manuals were never written in the first place. We don't sell anything. We fix things. That focus keeps us honest and keeps the work slow, careful, and done properly.

We believe old instruments deserve to keep making music, not gather dust in attics or fetch prices only collectors can pay. Whether it's a cracked keybed, a dying power supply, or a voice that's gone quiet, we'd like to help bring it back.

Patchbay is a small workshop in Rotterdam where old synthesizers come back to life. We are three people — a former recording engineer, a self-taught circuit obsessive, and a classically trained pianist who fell in love with broken machines — and between us we have spent decades coaxing sound out of equipment the rest of the world gave up on.

We started Patchbay because we kept meeting the same problem: beloved instruments sitting silent in attics and studio corners, written off as unfixable. A Juno with a dead voice chip. A Prophet that drifts out of tune. A Moog that hums when it shouldn't. To us, none of these are lost causes. They are instruments with history in them, and they deserve careful hands, original parts where possible, and honest work.

Every synth that leaves our bench is played, tested, and listened to — because that is what it was made for.
