GLM 5.3 vs Nemotron 3 Ultra

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.

Patchbay began in a narrow workshop on the edge of Rotterdam’s Noord district, where the hum of aging oscillators meets the rhythm of the city’s canals. Founded by three synth enthusiasts — a former studio engineer, a circuit designer, and a musician who still plays the same Juno‑106 he bought in 1986 — the studio grew from late‑night repair sessions into a dedicated space for restoring the instruments that shaped electronic music’s golden era. Every unit that passes through our bench is treated with the same reverence we give a first‑press vinyl: capacitors are swapped, contacts cleaned, and calibration traced back to original service manuals. We don’t just fix synthesizers; we listen to their history, understand their quirks, and return them to the stage or studio ready to inspire the next generation of sound. Patchbay is small, intentional, and built on the belief that vintage gear deserves a future as vivid as its past.
