Artist multi-item tag

[stefano_mbp]

As many of us know Artist tag is a multi item tag and Minimserver manages it in the right way.
But this “peculiarity” of Artist tag is not true for Alac (m4a) file type.
I came to Minimserver arriving from iTunes and Audirvana, iTunes is quite “superficial” but Audirvana simulate the multi item characteristic (JRiver does it as well) quite well.
Starting with Minimserver was a real chock when I realized that, according to the standards, there was no way to let Alac Artist tag to be managed as a multi item tag.
Therefore I have some hundreds Alac albums in which Artist tag is shown as:
Artist-a;;;Artist-b;;; .......
I can live with this of course but this is a big compromise, the alternative should be to transcode all Alac files to flac .... very tedious and time consuming, and lesson learned is never use Alac again ...
My question to Simon is:
can you have mercy on those of us who have this situation and realize a “trick” like Audirvana to simulate a multi item tag for Alac files? Maybe giving us the possibility to define which separator is to be used (ie “;;;” or “///“ or .... as different editors use different separators)?
Thank you for your attention
