Hi phooka,
might be true. However i have iPad Air with 64 GB with iOS 7. If i use Cubasis Version 1.6, it does work absolutely fine. Once i upgraded to 1.7 / 1.71 i had issues with Audio stuttering.
I could recover my Cubasis 1.6 from the recycle bin and don’t experience similar issues like with the 1.7 Version.
Could be a mixture of both? iOS issues and Cubasis issues?
