Hi Neroangelo,
Reading your reply it seems that you’ve reached the limit of drive space of your iPad device (that’s why Cubasis complaints here).
The following Apple link explains where to look how much storage is used on your iPad device (in order to decide what to delete to free disk space): How to check the storage on your iPhone and iPad - Apple Support
Regarding the Cubasis crashes:
Please make sure to provide me with the crash reports via PM in order to have them checked by our engineers.
Please follow this link to learn where to retrieve them: Steinberg Forums
Thanks
Lars
