Thanks you for your help.
By the second column I guess you're thinking of the artist/guest artist/performer/remixer options? That is unique to the artist splitter, and actually puts guest artist, performer, and remixer in their own special tags, not in the artist tag. About the closest you could come with a custom tag would be something like Artist (Instrument).
Yes, this is what I want to do, and as I supossed that`s only possible in the Artist tag.
I don't see why not. You will have to find a proper delimiter character and use the $Split function to achieve what you desire.
I've tried it with $ Split function, but not exactly what I'm looking for.
I'm using a custom tag (Musicians Credist List) for difrentes musicians involved in an album. Different values are separated by a semicolon (John Coltrane / Tenor Sax; Elvin Jones / Drums, ...). This splits the tag in different rows, one for each artis / instrument.
With the function $Split (<Musicians>, /, 2), I get "Tenor Sax; Elvin Jones / Drums, ...", because it can not distinguish the values separated by semicolons.
Anyway this is a good information, and I'm sure It will be useful sometime.
What I'm trying to achieve is to sort and search all musicians not only by his name but also by his instrument.
But you can not get everything
