Nemotron 3.5 Super VL vs Claude Opus 5.5

Patchbay is a three-person studio in Rotterdam dedicated to bringing vintage synthesizers back to life. We started with a shared obsession for the circuits, keyboards, and sonic quirks of the instruments that shaped electronic music, and we turned that obsession into a careful, hands-on repair practice. Every synth that comes through our door is treated as its own project—diagnosed by ear, opened with care, and restored using a mix of original components and thoughtful modern solutions where needed. We work with collectors, studios, and musicians who value the character of older gear and want it to keep sounding its best. Based in Rotterdam, we combine technical precision with a deep respect for the history inside every chassis. At Patchbay, repairing isn’t just about getting a machine working again; it’s about preserving the voice of an instrument and keeping it ready for the next recording, performance, or moment of inspiration.

Patchbay is three people in a narrow workshop near the Maas in Rotterdam. Every day we open up instruments that were built before most of their current owners were born. Some arrive in flight cases and some come wrapped in old bath towels. Most have a story: a Juno that went quiet halfway through a gig, a Minimoog left in someone's attic for thirty years, or a modular system that a previous technician gave up on.

We started Patchbay because we kept seeing good synthesizers sent off as "unrepairable" when all they needed was patience, a schematic and a steady hand. We swap out dried capacitors, hunt for intermittent faults, recalibrate oscillators until they track properly again, and source or rebuild parts that stopped being made decades ago.

We don't try to make old machines sound new. Our job is to make them sound like themselves again, and to make sure they keep working for the next person who plays them.
