What is NuCorder? The online music rehearsal app

NuCorder is an app that lets musicians play together remotely, in real time, as if they were in the same room. Thanks to its low-latency technology, you can rehearse and jam with your fellow musicians in France and neighbouring countries — physical distance remains a constraint, but at the scale of a country or between European neighbours, it works.

Built by music enthusiasts from the tech and music production world, NuCorder is designed as a complement to rehearsal studios: prepare your sessions remotely, then meet in the studio to finish the work.

Who is NuCorder for?

• 🎸 Bands: Rehearse together without travelling, at any time of day.

• 🎹 Remote musicians: Collaborate with artists in France or neighbouring countries.

• 🎓 Teachers & students: Give or take music lessons online with natural, low-latency sound.

• 🌐 Community: Find new musicians through the built-in social network.

How does it work?

The key to NuCorder is ultra-low latency. Unlike Zoom or Google Meet, designed for voice and video, NuCorder is optimised for real-time music — every millisecond counts when playing together.

The platform also includes a music social network: search for musicians by instrument or style, join open sessions, and maybe find the members of your next band.
