A number of my albums are simply not shown in Roon, but are accessible in JRiver Media Center. I have indicated which ones in yellow (this is just from my Shostakovich collection, but the problem is ubiquitous.
Have you made any edits to this content in Roon?
Is the album identified in Roon?
Is this content from local files, TIDAL, or Qobuz?
I assume that each folder represents a complete album and you haven’t created folders for individual works or collections of works?
I notice that you have a folder “Shostakovich Symphonies Nos. 2 & 15 - Liverpool - Petrenko”. This album is certainly known to Roon, so I’m not sure why it would not be identified. Perhaps Roon is being thrown off the scent by your metadata for that album?
The term “Watched Folder” in Roon means the root folder, which will have a hierarchy of sub-folders within it. Do you mean that you have just one Watched folder defined in Roon, something like \\nas-home\Musikk ?
Looking at your screenshots again, I see that you have a folder titled Stravinksky Capriccio Shostakovitch PC 1 Ogdon ASMF Marriner-FLAC-352k-24b
Is this the original Argo release that you have ripped, or is it disc 4 of the Decca re-release boxset that was released in 2011? Because that boxset is definitely known to Roon.
Sorry, but I’m sure it is a combination of the metadata and the fact that you seem to have rearranged the downloads by splitting each symphony into its own folder. If I look at the 11 CD release, the symphonies are arranged differently across the CDs.
Yes, that seems to be a likely explanation. So how do I get back to where Roon wants this to be? And can you recommend a good metadata editor so that I can manually re-edit the metadata of the missing cds to Roon’s liking?
Right, so it would appear that HDTT make their own organisation of material - they do not make a straight correlation with album releases.
So then you have major work ahead of you if you want to use this material in Roon. Roon recognises album releases. If it can’t make a match with a known album or box set, it will fall back to relying on the metadata in the files, and group files in a folder into an unidentified (by Roon) “album”. In this situation, you need to have very good metadata if Roon is to make connections with artists (performers), composers and compositions.
So for example in the Stravinsky/Shostakovich album, your current artist field has “Ogdon, Wilbraham, ASMF - Marriner”. Roon won’t recognise this, you would need to have “John Ogdon, John Wilbraham, Academy of St Martin in the fields, Neville Marriner” as the metadata for Roon to make the necessary connections in your database.
You asked for recommendations for a metadata editor. A simple, but good, editor that many in the forum use is Mp3tag. There’s also Songkong, which uses acoustic matching to identify files. That may produce better results for less work from you for your collection. The developer of SongKong is active on the forum.
