When two values in the tag/field Composer are separated with a semi-colon the second name disappears.
When separated with a forward slash or comma the result is “Isaac Albéniz/Fritz Kreisler [Arr.]” without it being separate (i.e. clickable) names like when you name two artists.
It seems like a glitch to me, because with Artists it works fine
The first screenshot indicates that the Artist tag contains two names and the Composer tag as well.
The second screenshot indicates that the two artists from the Artist tag are both displayed correctly in Audirvana, however the composer and textwriter in the Composer tag in Audirvana only display the first Audirvana
Then third screen shot indicates that I added the second composer name manually in the Audirvana Composer field and now all of a sudden it is displayed correctly.
The fourth screenshot indicates that the Composer tag of the file did not change
So I derive Audirvana is capable of displaying two names in the Composer field (if added manually), however Audirvana somewhere goes wrong in the reading and writing of the Composer tag in the Composer field.
I would appreciate any help in this respect since manually adding this information is nog do-able in a 60.000+ tracks database.
Meanwhile I found out that despite two names now being displayed in the Composer field, they are considered a single value (“Robert Schumann; Gustav Pfarrius”). In stead of two values (“Robert Schumann” + “Gustav Pfarrius”) meaning you cannot select these individually
