Claude Opus 5.5 vs MiniMax M3

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.

Patchbay began in a cluttered apartment in Rotterdam, where three friends spent weekends coaxing old synthesizers back to life. What started as a shared obsession quickly outgrew the living room. In 2016, we opened our first proper workshop in a converted warehouse on the south side of the city, and we have been soldering, calibrating, and listening closely ever since.

We are a small team of three. Niels handles the analog work, coaxing warm tones from aging oscillators and reluctant filters. Marijn focuses on digital systems and the occasional stubborn MIDI quirk. Sanna manages restorations, sourcing rare components and keeping long projects on track. Between us, we have decades of experience with the machines that shaped electronic music.

Every synth that passes through our doors carries decades of sound inside it. Our job is to make sure that story continues.
