Can I access my music from the SSD, inside my Nucleus without a subscription?

[RBM (René)]

Here’s a quote of Roon’s COO about what would happen in the unlikely event that Roon would go out of business:

What happens with the lifetime subscribers if the company folds or is sold?

Yah, I get it. So right now, the application obviously logs in to our cloud services, for both metadata and membership checking. In the unlikely event that we could not maintain those services, we would release one last build that would kill those dependencies, so you could continue to use the application without our infrastructure as a requirement. Obviously the functionality would be reduced, but it would work.

As for your music: RoonOS is Linux at its core, beit highly optimized for running Roon. Your music is shared though SMB – this will continue to be the case even is the Roonserver part is not running.
