This way you can import or export many formats (wave, mp3, jpg, docs, Cubasis projects…) inside many apps like AudioShare, Cubasis,… (i.e. open-in). You have to use a iOS filehub-app to manage your files. These are ‚FileHub Plus‘ or ‚RAV Filehub‘.
There are some videos on YouTube like:
I hope, this solve your (and others) point.
