Mi:dm K 3.0 Pro vs GLM 5.3

Patchbay is a three‑person workshop rooted in the heart of Rotterdam where a shared passion for analog sound meets meticulous hands‑on craftsmanship. Founded by longtime synthesist‑technicians who grew up chasing the warm, unpredictable tones of classic machines, we treat every instrument as a living piece of musical history. From the battered faces of 1970s Minimoogs and ARP 2600s to the rare circuitry of vintage Japanese modules, each repair begins with a careful diagnosis, the sourcing of authentic components, and a respect for the original design philosophy. We document every step, communicate openly with owners, and strive to return each synth to the character that inspired its acquisition while ensuring reliable modern performance. Our blend of technical precision, artistic intuition, and transparent service has helped artists across Europe keep their rigs alive, preserving distinctive voices that might otherwise be lost to time. Patchbay is committed to keeping analog synthesis thriving for future generations through integrity, skill, and a deep love for the sounds we resurrect every day.

Patchbay is a three-person workshop in Rotterdam where vintage synthesizers come back to life. Whatever lands on our bench — a battered Minimoog, a Juno with dead keys, an ARP silent since the eighties — gets the same treatment: careful diagnosis, honest advice, and repairs done right.

We started Patchbay because we believe a good synthesizer shouldn't die of old age. These machines are more than circuits and sliders — they're the sound of records you grew up with, and the reason some of us got into music in the first place. Every one we fix goes back out into the world ready to make more.

Between us we handle everything from recapping and calibration to keybed work and the hunt for parts nobody has made in decades. It's slow, meticulous work, and we like it that way. If something in your collection hums, crackles, or refuses to turn on, bring it in — we'll see what we can do.
