Which countries can I use NuCorder in?
NuCorder doesn’t restrict access to its recommended coverage area. However, the quality of a remote rehearsal depends on the distance between the musicians and the servers, as well as each participant’s internet connection.
The main servers are located in mainland France. Since October 10, 2026, we’ve also been deploying servers in different European cities to improve coverage, mainly on weekends.
In other countries, the service remains available on a best-effort basis, with no guarantee of results. It may work if the distance and connection conditions allow.
Recommended coverage area
Mainland France
Being close to the servers generally provides the most favorable conditions.
Belgium
Belgium is within the area that the current infrastructure can reasonably cover.
Luxembourg
Luxembourg is within the area that the current infrastructure can reasonably cover.
Andorra
Andorra is within the area that the current infrastructure can reasonably cover.
Great Britain
We’re deploying test servers in London on weekends to improve coverage.
Italy
We’re deploying test servers in Milan on weekends to improve coverage.
Germany
We’re deploying test servers in Frankfurt on weekends to improve coverage.
Switzerland
Switzerland is within the area that the current infrastructure can reasonably cover.
Important: Even if you’re in the coverage area, make sure to test NuCorder under real-world conditions. Quality also depends on your internet provider, how your data is routed across the internet, connection stability, and each musician’s setup.
Can I use NuCorder from another country?
Yes. NuCorder doesn’t block access from countries outside the recommended coverage area.
The service is available there on a best-effort basis: it will provide the best quality the available conditions allow, but results aren’t guaranteed. Musicians who are relatively close to the servers may have a satisfactory experience, while greater distances or an unfavorable network route can make playing remotely more difficult.
Your country alone isn’t enough to predict the quality of a session. The best way to find out whether NuCorder suits your situation is to try it with the people you want to play with.
Why does distance matter?
During a rehearsal, each participant connects to a NuCorder server. Each musician’s audio has to reach that server before it’s sent to the other participants. The longer this takes, the more noticeable the delay between musicians may become.
Quality depends in particular on:
The distance between each musician and the server hosting the session
The route the data takes across the internet
The stability of each connection
Whether an Ethernet cable is being used
Each participant’s computer, audio interface, and settings
A fast connection alone isn’t enough: stability and response time are essential too.
How can I test NuCorder from my country?
For a representative test:
Install NuCorderDesktop on each participant’s computer.
If possible, connect each computer to its modem or router with an Ethernet cable.
Create a private session and invite the musicians you usually play with.
Check that audio works in both directions, then play together for a few minutes.
The free plan lets you check your setups and test a private session for up to 30 minutes. After signing up, the getting-started process also lets you test on your own or with others, with no time limit.
