Muse Spark Open vs MiMo v2.6 Pro

Patchbay is a small studio in Rotterdam where vintage synthesizers come back to life. We are three technicians, musicians and longtime collectors who have spent the last decade trading schematics, hunting spare parts, and learning the quirks of every oscillator and filter that has passed through our hands.

What started as helping friends keep their Junos and ARPs in tune has grown into a dedicated workshop in the north of the city. We repair, restore and service instruments from the sixties to the early nineties, from well-known classics to rare prototypes that barely left the factory.

We believe these machines are more than equipment. They carry histories, imperfections and sounds that cannot be replaced. Our job is to respect that character while making sure each instrument is reliable, playable, and ready for another lifetime of music.

Patchbay is a three-person studio in Rotterdam dedicated to the repair and restoration of vintage synthesizers. We spend our days with soldering irons and oscilloscopes, coaxing life back into instruments that were built to last and mostly did, until they didn't.

Between us we cover decades of combined experience with analog and early digital circuitry, from the classics of Roland, Korg, Moog, and ARP to the odd, wonderful machines that never made it big. We treat every repair with the same care, whether it's a flagship polysynth or a broken drum machine with a devoted following.

Our workshop sits in the west of the city. You're welcome to visit — bring the instrument, bring the story behind it. We like hearing both.

What we don't know we research, and what we can't source we sometimes fabricate. Nothing gets written off before we've tried.
