I’m trying to create a script to copy ID3v2.4 frames that foobar2000 doesn’t read to TXXX frames, but I can’t figure out how to copy the list of performers with instruments. According to the tag mapping, the internal name for performers is
performer:instrument, but that only works if you specify the instrument (like
performer:piano). The script
$copy(_id3:TXXX:Performer,performer) doesn’t work.
In other tagging formats, you get a list of artist (instrument), artist (instrument), etc. How can I get that in an ID3v2.4 tag?
