Hi Hebreww,
Thank you for your message.
Please follow these steps first:
- Load an empty Cubase project
- Close all open apps
- Shut down and restart Cubasis
Once done, please check if Cubasis crashes when using the app on its own.
If things work as expected, keep up adding 3rd party instruments/effects plug-ins.
If you stumble on a problem, please let us know the exact steps how to reproduce it.
In addition, please have a look at our Cubasis 3 performance article, to check if it is of additional help:
Final question:
Did you recently update to iOS 14, and could the issues be related to using 3rd party AU plug-ins in the projects?
If you instead want to see a refund for your app purchase, please get in touch with Apple.
Please keep me updated.
Best,
Lars
