Grok 4.7 vs Nemotron 3 Ultra

Patchbay is a three-person studio in Rotterdam devoted to the repair of vintage synthesizers. We work on instruments that have already lived a long life on stages, in studios, and in spare rooms, and we treat each one as something worth keeping rather than replacing. Our benches are set up for careful diagnosis, component-level repair, and the slow work of bringing an old circuit back into reliable use.

The three of us share the shop, the tools, and the jobs. One person may trace a failing voice while another sources a part or recalibrates an oscillator; we pass instruments between us until the sound is right and the hardware is stable. Clients come to us with analog polys, early digital machines, drum boxes, and the odd modular that has been patched and repatched for decades. We listen first, then open the case.

We are not a museum and we are not a showroom. Patchbay exists so that working musicians, collectors, and curious owners in Rotterdam and beyond can keep playing the instruments they already love.

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.
