trouble with Audirvana and multipl artist tag

[pask]

Skeptic, i'm very thankful for your help and the time you took to explain me the MP4/MA4 attribute tag.
It's much more clear for me now that the multi tagging issue I have doesn't come from Audirvana or Minimserver supported tag, but the apple lossless files. I've been a long time iTunes user, and this format was the only I used at that time for lossless files... damned.

Thanks Simon again for your support and the job done on Minimserver, awesome !

Well, I must now decide between using Audirvana on a Mac + the dedicated remote app on iPad for a much 'sophisticated' library browsing, or use Minimserver + Lumin App on my iPad and forget about the All Artists tag and only use 'one value' only tag (Artist, Composer, gendar etc.)

Or, convert all my M4P to FLAC

Thanks again to both of you
