Hi Aviad,
Thanks for your message.
Of course, Cubasis allows to import WAV files (and other audio formats) via AudioPaste, iTunes library import, iCloud Drive, Dropbox etc.
Please find more details in the MediaBay/Import section of the in-app help which is available as a browser version for you to look at: MediaBay
In case, you’re interested to learn more about Cubasis’ workflow, please have a look at the available tutorials right here:
Hope that helps!
Best,
Lars
