Cubasis remains silent on Android 13 when using an external audio interface (USB).
The cause is a bug in Android 13 that occurred when MIDI 2.0 support was introduced.
If you are using Cubase with an audio interface and your tablet or phone is running Android 12, we recommend not updating to Android 13 for now.
Cubasis 3.5.1 introduced a new option in the setup to disable MIDI I/O. This works around the audio problem, but MIDI hardware can no longer be used.
Google is working on a solution. For questions about the status of the bug fix in Android 13, please contact Google.
