Perhaps of use to others:
I am often travelling in places with bad/no wifi. I sill like to be able to play high res music from my iPad in those situations. I have a deep catalog of FLAC files on an external SSD. It turns out, however, that almost all apps won’t let you play anything more than a single song from an external drive. They all force you to import before playing, which is not tenable with large files. After a frustrating run of trying to find a solution, nPlayer seems to be one of the few to do it. Still not perfect, but the best I’ve found. *Anyone else have solutions?
