Step 5 Preview vs MiniMax M3

Patchbay is a three-person workshop based in Rotterdam, dedicated to keeping vintage synthesizers alive and playable. We are technicians, musicians, and obsessive tinkerers who believe that classic analog instruments deserve better than silence. From temperamental Jupiter-8s to worn-out ARP Odysseys, we restore, repair, and maintain the machines that shaped the sound of modern music. Every repair starts with listening—both to the instrument and to the person who plays it. Whether you are chasing a rare fault, need a full calibration, or simply want your old synth to feel new again, our bench is open. We understand that no two synthesizers arrive with the same story, and we treat each circuit, slider, and key with the care its history deserves. At Patchbay, we are here to make sure the sounds of tomorrow are built on those that came before.

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.
