hey Saphired,
while testing various Ipads with all sorts of settings, we’ve experienced some issues once your disk has not enough free space. Even if there’s 2 Gigs left, this could not be enough.
So first thing for you to do is, make sure to emty the trash bucket within the Mediabay of Cubasis. You can tap and hold the delete button to delete all files at once. In case this doesn’t change anything, make some more space on your disk.
If you’re still not able to complete your mixdown, we recommend to download a performance-measurement-tool and provide us with your disk-write and -read velocities in MByte/sec.
Hope that sorts it out for you!
kind regards
Ludwig
