Thank you for your message.
In regards to Cubasis 3, we’ve previously released an update which addressed 30+ user-reported problems. These detailed reports have been extremely helpful for us, in resolving the issues. At the end of this month, Cubasis 3.0.2 will be released, which will bring back Apple Pencil Support and the MiniSampler Edit functionality, alongside resolving further issues.
We are absolutely fine about your decision to stick with Cubasis 2, and there are no worries to do so.
However I’m not keen about your statement in regards to Cubasis 3, not having used the app yourself so far.
Please stay healthy
& best wishes,
