Storage and access to large audio directories on iSO.

I’m new to iOS and Cubasis so please excuse me if I’m asking a stupid question.
Given that iOS doesn’t give you access to the directrory structure, how and where would you put your sample library?
And how do you access it.
I haven’t bought Cubasis yet and can’t see the answer in the manual.
With Caustic I have to import from Audioshare where I save all my samples.

Cubasis allows you to import audio and MIDI files. There are several ways to exchange between the app (e.g. iTunes File Sharing, Wi-Fi etc.).

Please find more details about the available options in the Cubasis manual to be found right here:
