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.
