I thought I was making progress when I copied your Import Settings. When I did that, “Performed by” did appear under the track I was testing. But when I tried to remove “Test” by “Performed by”, it would not go away, nor could I edit it in mp3Tag. I still could not figure out what tag in mp3Tag Roon was reading to get the Performed by information.
Out of frustration, in mp3Tag and dbpoweramp I deleted any reference to a Personnel tag. When I did that, the “Performed by Test” info went away in Roon. I tried adding in the Personnel tag again in mp3Tag, but I’m back to square one where Roon will not display Performed by under the track when I enter the data in mp3Tag under Personnel despite my new Library import settings.
I believe the problem is I don’t know the exact steps to properly add the appropriate tag (is the correct tag PERSONNEL?) in mp3Tag. It’s odd that I had no trouble adding the ROONTRACKTAG in mp3Tag, but cannot seem to correctly add the PERSONNEL tag using the same steps.
The screenshot you posted I believe just shows how to make an existing tag field visible in the Tag Panel on the left of the screen. I don’t believe it actually adds the new tag to mp3Tag.
Would you do me a big favor and post the following…
Go to the top and click on View, then Customize Columns. Do you see PERSONNEL in the list? If so, click on it; what does it say beside Name, Value, and Field?
Also, Click on View again, then Extended Tags. Do you see PERSONNEL in the metadata list? If so, what does it say beside it?
