Roon has a huge following, especially as it’s being embedded within major manufacturers products: Marantz, Denon, Zidoo, Dune, etc. It’s continuously being updated, adding features, services, etc. It can also run on MANY NAS devices…
Did I say something inaccurate?
I believe I correctly surmised the way it works. The "Core" product can run from Windows, Mac, or the custom Roon hardware. This is the software that then integrates with the various hardware devices in your system (e.g. HEOS) as well as any of your music sources (e.g. Tidal). There are then a couple different apps / clients they provide to allow you to interact with Core - these apps are the ones that allow you to control playback, browse your catalog, etc.
I have a largeish HEOS implementation, so its interesting to me from that perspective. The lack of support for mainstream music streaming platforms (e.g. Apple, Spotify, Amazon) is a shortcoming in my view as I have Amazon Music Unlimited family plan.
To Will's point - and everyone knows how much Will and I see eye-to-eye (!!) - what are you envisioning using Roomie for with Roon? Do you envision that Roomie would be an additional means to control the "Core" software I described above?
It might be helpful to express your desires in the format "As a . . . I want . . . so that . . .".
As a Roon and Roomie user
I want to have Roomie be a control point for the Roon core software
So that I can further consolidate on Roomie as my universal remote and eliminate the need to use the Roon apps
