I have a bluesound vault. Do I have to have the app running on my computer to run the program. Or can I just run it on my iPad. If I run it from my iPad can I control everything from the bluesound app or from the iPad app?
You need the core (server) running on a Mac or pc or a Linux system or you can install with a nas package (Announcing Roon Server packages for QNAP and Synology). You then point roon to wherever your music is stored.
