Muse Ember vs Nemotron 3.5 Super VL

Patchbay is a three-person studio in Rotterdam repairing vintage synthesizers. We work carefully, one instrument at a time, because old machines deserve patience. Our bench is crowded with test leads, spare knobs, tired capacitors, and service manuals held together by tape. Every repair begins with listening. We power up the synth, play a few notes, and trace the fault by ear before opening the case. Perhaps the filter drifts as it warms. Maybe a voice cuts out, or the envelope behaves strangely. We clean contacts, replace components only when necessary, and keep original parts wherever possible. We believe repair is a form of preservation. These instruments were built to be played for decades, not replaced when something small fails. Rotterdam has a long history of making and fixing things, and we are proud to continue that tradition. Bring us your beloved keyboard, and we will see what can be saved.

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.
